A clump of a few hundred stems, in two discrete groups that may be separate plants, was found in stabilized, sandy soil approximately 20 meters from the Pacific Ocean growing amongst Simmondsia chinensis (Jojoba) and Cylindropuntia cholla. Despite the proximity to the ocean, the view here is hardly scenic, with the huge San Pedro Electric Generation Plant loom- ing less than two kilome- ters to the east. This specimen of Cochemiea halei had several withered floral remains, fresh fruits, and only a single open flower on the 8th of June, 2007. This plant appeared quite healthy and active- ly growing, but no other individuals were found in the immediate vicinity. Sand dwellers, such as Abronia sp (Sand Verbena) and Probos- cidea parviflora grew here along with succu- lents Stenocereus eruca (the Creeping Devil), Ferocactus townsendianus, and the following taxa that are ubiquitous throughout the peninsula: Pachycereus pringlei, Stenocereus gummosus, Mammillaria dio- ica, Fouquieria diguetii, Bursera microphylla, and B. hindsiana. The foggy Pacific contributed to most plants being cov- ered in lichens, but not Cochemiea halei. v 2007 VOLUME 79 NUMBER 6 275.

Plantings dating back to 1908 and still thriving give the garden much of its character. Their bright festive panicles of white blossoms add a cheery background and accent to the symphony of spring color in the lower Desert Garden. According to the latest authorities there are 45 yucca species and 14 varieties and they are placed in the agave family. Most of the species are found in the Southwest, northern and central Mexico and Baja California. But the genus is more widespread with species found along the Atlantic seaboard, the Great Plains, into Canada, and south as far as Guatemala. Yucca blossoms, with the exception of at least one species (the rose-tinged Yucca endlichiana) are mostly creamy white.

Creeping Devil Cactus Stenocereus eruca Also known as: Caterpillar Cactus, Casa de Ratas Machaerocereus eruca Rating: 0.0 ( 0 votes) This description is for Creeping Devil Cactus (Stenocereus eruca): To the eye, stenocereus eruca looks as though it has simply collapsed to the ground, but in fact, it is one of the very few species of ground hugging cacti. Commonly known as the creeping devil cactus, it is far from being a friendly plant. It has large, sharp dagger-like spines that make walking over them extremely difficult, and smaller, needle-like spines to cloak its dark green stem beneath. It flowers in spring, producing narrow, trumpet- shaped blossoms at night, usually pink or white. A lover of sandy, well-drained soil, it is an interesting choice for garden groundcover, but the required hot climate reduces its suitable locations to just a few.

Wynne | 48 pages | 01 Oct 1997 | McGraw-Hill Education - Europe | 9780070579347 | English | New York, NY, United States Cactus Desert PDF Book Finding Water in the Desert Water is a basic need for any living organism. Who knew a cactus could be whimsical? The seeds pass through their digestive systems and are deposited in their droppings. You'll only find these in Baja, Mexico in the desert. Development takes many forms. The bunny ear or angel wing cactus is a popular choice for its cute shape. In the genus Pereskia , the branches are covered with leaves, so the species of this genus may not be recognized as cacti. This brings about the question of how the plant can carry out photosynthesis without leaves. However, cacti are very difficult to preserve in this way; they have evolved to resist drying and their bodies do not easily compress. There are over species of this plant scattered in deserts all over the globe. They have persistent leaves, and when older, bark-covered stems. Thus, Stenocereus eruca has stems growing along the ground, rooting at intervals. Some studies have shown that the pectin contained in the Prickly Pear pulp lowers levels of "bad" cholesterol while leaving "good" cholesterol levels unchanged. Although spines have a high surface area-to-volume ratio, at maturity they contain little or no water, being composed of fibers made up of dead cells. The cactus family is one of the most easily recognized plant families in the world. The plant is a native of Africa, America, Australian, and Europe, and many different species exist in the desert environment.

In this work we contribute to the knowledge of the reproduc- tive phenology of Stenocereus stellatus (Pfeiffer,Riccobono), a columnar cactus that produces fruits of high commercial perspectives known as “pitayas”. This kind of pitayas are produced for local commercialization in back orchards in some regions of the Mexican dry tropics. These fruits are produced only in the apical part of the cactus “arms”. Our results show that fruit development of pita- yas is highly associated to the rainy season of the year. This behavior is different from the reproductive strategy of other columnar cactus species that produce other kinds of pitaya in the same ecological region. Key words: Columnar cacti, pitaya fruit, phenology, water stress. 1 Centro de Desarrollo de Productos Bioticos IPN, Km 7.5 Carretera Yautepec-Jojutla, Morelos, México. 2 Instituto de Investigaciones Químico-Biológicas, Universidad Michoacana de San Nicolás de Hidalgo, Edificio B3 Ciudad Universitaria, Morelia, Mich.

Flowers of some other cacti are subtended by modestly large photosynthetic leaves. Many specimens of the organ pipe cactus, Stenocereus thurberi, seem to have all these traits: large short-shoots with indeterminate growth and fleshy photosynthetic leaves. Short-shoots in organ pipe cactus grow new photosyn- thetic leaves at their apical meristem and sometimes flower, branch, and form discrete areoles with new spines. However, unlike short-shoots in Neoraimondia, spherical short-shoots of Stenocereus thurberi seem to retain chlorenchyma and lack extensive cork development.

Observations on Distribution and Habitat Characteristics of the Endangered Mexican Endemic Cacti Stenocereus Emca
Journal of Arid Environments (1995) 29: 55-62 Observations on distribution and habitat characteristics of the endangered Mexican endemic cacti Stenocereus emca Jorge Cancino, Heidi Romero-Schmidt, Alfredo Ortega-Rubio & J. L. León de La Luz Centro de Investigaciones Biológicas de Baja California Sur. A .C, Apdo. Postal No. 128. La Paz, 23000, BCS. México (Received 29 January 1993, accepted 13 Apn'l1993) Six 100 x 100 m quadrants were established in the arid area where Stenocereus eruca has been recorded, al1 individuals were counted and measured and the main habitat characteristics recorded. A new distribution record is reported, but these observations indicate that the original range is threatened. It is recommended that the establishment of a reserve in the northern part of the range where habitat characteristics promote locally abundant populations and thus implement a genetic reservoir in order to guarantee the conservation of this unique endemic cacti. Keywords: Baja California Sur; cacti; chirinola; conservation; arid México; Stenocereus eruca Introduction Stenocereus eruca (Brandegee) Gibson & Horak is an unique succulent plant species, one of the more curious cacti of the world (Gibson & Nobel, 1986). It is the only cactus of arid México which does not grow erect; instead, its almost unbranched stem is totally flattened and horizontaily creeps over the soil (Fig. 1) with only the apex raised for a few centimeters above the soil surface. The mode of propagation of S. eruca is mainly vegetative: each stem develops a few ramifications which eventuaily form new individuals by the separation from the original stem by lengthening followed by tissular death of the link section.
