However, their popularity has not waned, sustained by their gloriously colorful, large, trumpet-shaped flowers. During Bob Schick's time as a volunteer at the Huntington 128 named cultivars were introduced. Since that time, we have strived to maintain the bona fide selections and have devoted a web page on the Huntington site in hopes of conserving them in cultivation. This is to avoid confusion with similar selections like the Harry Johnson hybrids and many newer selections that have been stimulated in part by Bob's work. We have been assisted in our efforts to conserve the original introductions by Adam Rettig, a nurseryman in Fallbrook, CA. Adam has been diligent in maintaining Bob's legacy of \u003cem\u003eEchinopsis  \u003c\/em\u003eselections. This includes propagation of prior selections as well as some that Bob named but have yet to be introduced. 'Asahi' is the first of the latter group.

Flowers open after dark the first night but can remain fully open for two days making these both nocturnal, like most epiphyllums, and diurnal, increasing their chances of being pollinated by nocturnal moths or diurnal bees among other pollinators.

These clearly function for mechanical protection from herbivores but, research has shown, can also help with absorption of condensed dew to help keep the plants hydrated during dry spells. The stout, jointed stems (joints to 20 cm long and 6 cm in diameter) clump to form a low shrub 0.5 m tall (to 1.5 m). They bristle with beige central spines to 8 cm long but these are sparse enough that the tuberculate stems are obvious, and one can appreciate the beautiful bluish color of the mature epidermis.

The beige stigmas are divided into 9 to 13 linear lobes and emerge from a bed of stamens at the base of the flower.

The plant occasionally reseeded itself in our shade house for a few years after ISI distribution. In 2009, Karen Zimmerman spied this unusual vegetative form in a seedling among our epiphytic cacti that occupy one side of the shade house. It had rosettes of leaves twisted counterclockwise resembling a pinwheel. This is due to the usually oblique shape of the leaves with the right margin longer, curved, and falcate. The shorter margin is notched below the middle giving the leaf blade a shape like the blade of a medieval halberd, a battle axe with a spike. The pinwheel is a gentler allusion and though the leaves are quite thick and immobile one can almost imagine them spinning in the winds of time. Occasionally leaves are straighter with hook-like notches on both sides of the leaf. Like the parent species, the leaves are gray green but with only scattered, minute teeth along the margins.

Instead of being mostly horizontal, these are decurved, that is, they arch and bend over, bearing the shorter racemes on the pendent portion.

Not only can the sunbirds perch atop the arched peduncle to reach most of the flowers in the basal portion of the raceme, but they may also perch on the sterile portion at the apex of the raceme to reach the more distal flowers.

These leaves provide one of the prime examples of the windowed leaf adaptation (along with various mesembs like \u003cem\u003eFenestraria \u003c\/em\u003eand the more succulent-leaved Peruvian \u003cem\u003ePeperomia \u003c\/em\u003especies. See ISI 2026-25) whereby the bulk of the plant body can stay protected from herbivores and desiccation underground while light can enter the translucent \"windows\" of the truncate leaf tip to be used for photosynthesis. The largely subterranean nature of the plants also provides a degree of crypsis, further protection from herbivores. Perhaps this explains why this now so popular subject of succulent collections was not described to science until the late date of 1910. The species is native to the Western Cape Province of South Africa where some natural variation can be observed. This variation has been exploited by breeders, initially in Japan, but now worldwide, to enhance various characteristics including size of the translucent, windowed leaf tip, texture of the leaf surface, and the degree of lineation or markings in the windows that add to its camouflage. The selection offered here is named to allude to these markings which ornament the large leaf tips that otherwise look like globs of jelly. The mysterious Nazca lines of Peru, created by ancient peoples for spiritual expression, are the inspiration for the cultivar name. The selection can be propagated vegetatively by division or root cuttings, but this can be an excruciatingly slow process. In nature, these fleshy roots not only store water but can be contractile, pulling the plant down into the sheltering soil. Should some persistent herbivore manage to dig deep enough to eat the entire rosette, the fleshy roots have the potential to resprout and grow new rosettes.

It was first introduced to cultivation by Dr. Erich Werdermann in 1933 and described by von Poellnitz in 1937. Werdermann (1892-1959) was a German botanist dedicated to the study of succulents, publishing extensively and becoming curator of the Berlin-Dahlem Botanical Garden from 1951 to 1958. But in 1933, he spent several months studying the collections at the Huntington, bookended by collecting trips to the SW US and Mexico. The \u003cem\u003ePachyphytum \u003c\/em\u003ethat bears his name was found on the earlier of those expeditions. The type collection was apparently the only one in cultivation for several decades until Reid Moran set out to re-collect it in 1966. He wrote a detailed description of the plant and the story of its re-collection in this Journal (39 (4): 154 -158, 1967). The species is somewhat variable in leaf shape and size but generally has oblong leaves with a rounded apex, somewhat flattened and widest in the middle. Our plant has leaves about 5 cm long with a lavender blush to its beige or grayish color. The flowers are borne in nodding cincinni pollinated by hummingbirds attracted by the red interior of the pendent flowers. As the fruits mature, the flowers turn upward and the persistent sepals dry and become thin, spreading, white and petal-like subtending the five alternating carpels which split open to release their fine, windborne seed. This morphology and these adaptations for pollination and seed dispersal are typical of cliff-dwelling Crassulaceae. We offer rooted cuttings of HBG 128859, a plant received from Myron Kimnach (2011.27).

Based on recent DNA analysis of three regions of the plastid genome, Paton et al. (Botanical Journal of the Linnaean Society, Vol. 188 (4): 355-376 (2018)) have found several formerly monotypic genera to belong to a single clade. However, \u003cem\u003ePerrierastrum\u003c\/em\u003e is distinctive and easily recognized among these with its pinnately divided, fleshy leaves that have earned it the common name of Madagascar mountain fern shrub. I'm not sure that name is any more convenient than the botanical name. In any case, the authors consider this species to now be one of six species, endemic to Madagascar, placed in the genus \u003cem\u003eCapitanopsis\u003c\/em\u003e, first published in 1916 for \u003cem\u003eC. cloiselii\u003c\/em\u003e S. Moore. Also distinctive are the inflorescences which contrast with the pinnately divided foliar leaves in having leafy, green but simple, ovate inflorescence bracts. The white flowers are zygomorphic and fairly typical of the Plectranthinae tribe of the Lamiaceae or mint family. Unlike many mints, the stems are not square in cross section. Nor is the foliage particularly aromatic. The plant will, indeed, grow into a somewhat gangly shrub about a meter tall and wide. A little pinching of the meristems will help keep it more compact. Until now, there was only one clone in cultivation, a plant collected October 23, 1995, by John Lavranos (30014), 15 km W of Ambalavao Madagascar, where it grew atop a granite dome. The generic name \u003cem\u003ePerrierastrum\u003c\/em\u003e would, at first glance, seem to commemorate Perrier de la Bâthie (1873 -1958), French botanist who lived and worked in Madagascar from 1896-1933. However, in this case it is derived from the Simaroubaceous genus \u003cem\u003ePerriera\u003c\/em\u003e, a tree from the wetter tropics of Madagascar, plus the diminutive suffix -astrum. The genus\u003cem\u003e Perriera\u003c\/em\u003e also commemorates Perrier de la Bâthie, incidentally. The epithet \u003cem\u003eoreophilum\u003c\/em\u003e refers to the plant's montane habitat (\u003cem\u003eoreo\u003c\/em\u003e = mountain, \u003cem\u003ephilum\u003c\/em\u003e = loving). \u003cspan data-olk-copy-source=\"MessageBody\"\u003eWe offer rooted cuts of HBG 148327 (not 82734 as published in the C\u0026amp;SJ — that is the Lavranos collection), propagated by Joe Stead\u003c\/span\u003e of Orange Coast College, Costa Mesa, CA.

In March 2018, we planted several in the lower Desert Garden. They thrived in our comparable climate, and we eagerly awaited their first flowering. In June of 2023, the first of these produced an inflorescence and we anticipated the yellow to chartreuse flowers described and illustrated for the species. When the first flowers opened a few days later, I was puzzled by the flower color, which was not at all what was expected but, rather, a pale, ghostly blue like that of some of the highly sought after high-Andean species. None of the other plants in the garden flowered that year nor have they since then. Following flowering, I checked for seeds in case the plant was self-fertile, but no capsules developed. The question was whether this was an unusual color variant of \u003cem\u003eP. gilmartinii\u003c\/em\u003e or a hybrid with the sympatric \u003cem\u003eP. alpestris\u003c\/em\u003e subsp. \u003cem\u003ezoellneri\u003c\/em\u003e Zizka, J.V.Schneid \u0026amp; Novoa which has emerald-green flowers. Every child painter learns that blue mixed with yellow makes green but was it possible that a yellow-flowered Puya crossed with a green-flowered one makes blue? This appears to be the case but will await DNA analysis someday to confirm.

Dick Wright, also a noted Echeveria hybridizer, created the hybrid by crossing \u003cem\u003eSedum morganianum\u003c\/em\u003e E.Walther (2n = 70) with \u003cem\u003eEcheveria derenbergii\u003c\/em\u003e J.A.Purpus (2n = 27). The discrepancy in chromosome numbers explains why the Sedum parent, the common \"donkey's tail\", seems to dominate in the hybrid such that it is commonly known as the super donkey's tail and is often confused with the parent species. It does resemble a robust \u003cem\u003eS. morganianum\u003c\/em\u003e and will produce pendent stems covered with overlapping, lanceolate, acute leaves, but these stems will only arch over the edge of a pot by a few inches while \u003cem\u003eS. morganianum\u003c\/em\u003e can form curtains of straight, hanging branches to 3' (a meter) or more.

A. Purpus in 1907 on the hills near San Luis Atolotitlán, in southern Puebla and was described by J. N. Rose in 1909. As he was impressed by its thick, succulent, cylindrical leaves he called it \u003cem\u003eS. allantoides\u003c\/em\u003e (Greek \u003cem\u003eallanto \u003c\/em\u003e= sausage). The flowers of the new species were greenish white, sometimes tinged with pink. However, the occurrence of \u003cem\u003eS. allantoides\u003c\/em\u003e is not limited to San Luis Atolotitlán. Its distribution area includes southern Puebla and northern Oaxaca, and subsequent findings show that this is a rather variable species. Leaves can be sausage-like or more flattened and rounded and flowers can have red spots on the inside of white petals, thus reminding one of the flowers of the genus \u003cem\u003eGraptopetalum\u003c\/em\u003e. Such a form was collected by Dudley Gold in 1954 and described by Matuda as \u003cem\u003eGraptopetalum goldii\u003c\/em\u003e. He obviously overlooked the fact that the plant differed in crucial characteristics from species of the genus \u003cem\u003eGraptopetalum\u003c\/em\u003e (the indication of the type locality as \"near Ixmiquilpan, Hidalgo\" is also in error). It was recombined in the genus \u003cem\u003eSedum\u003c\/em\u003e by V. V. Byalt in 2012, and for the sake of completeness, Sedum Society Newsletter 3, 1987 contains a description of \"Sedum allantoides form 'Goldii'\". To treat it as a cultivar is hardly merited as this is not the only clone with this leaf morphology. The cylindrical leaf form has inspired the evocative, though gruesome, common name in Spanish of dedos muertos, meaning dead man's fingers. I have never seen such fingers and am happy to leave that to the imagination. Another species with similar flowers is\u003cem\u003e Sedum alexanderi\u003c\/em\u003e which has larger, flattened discoid leaves.

Meanwhile we acquired another Bruyns collection that we distributed as ISI 2009-28. These were grown by C\u0026amp;J nursery from seed collected in the hills around Robertson. We distributed divisions of multiple clones, a few of which persist, but this has proven to be a rather finicky stapeliad prone to rot. The Shoal Creek plant, meanwhile, filled a pan in the Desert Conservatory and became a wonderfully floriferous display specimen. When the Conservatory was under renovation starting in April 2022, the entire collection was relocated to a shade house with the expectation that renovation would be complete by the following October. Renovations dragged on and we found ourselves inadvertently conducting a grand experiment into the tolerances of a diverse collection of succulents for our Mediterranean climate including winter rains and cool winter temperatures. It turned out to be quite instructive as to what preferred shade house conditions and what didn't. The Shoal Creek Stapelia turned out to be fine in the shade house, flowering as well or better in outdoor conditions with more ventilation and UV light.
