Description
Flowers are gigantic intense hot pink-purple, abundant and scented, 5-7 cm long. Echinocereus reichenbachii is cold-hardy and endures severe frost as long as it is kept dry. Family: Cactaceae (Cactus Family) Scientific name: Echinocereus reichenbachii ssp. reichenbachii (Terscheck ex Walpers) Haage Jr. ex Britton & Rose Origin: Southwestern USA (Colorado, Kansas, New Mexico, Oklahoma, Texas), northeastern Mexico (Coahuila,Nuevo León, Tamaulipas) Habitat: Chihuahuan Desert, desert scrub, grasslands, oak-juniper woodlands at an altitude of 0-1500 m; It thrives in a variety of sites and soils often found growing out of cracks in solid rock. Conservation status: Listed in CITES appendix 2. Common English Names include: The popular name of Echinocereus reichenbachii is Lace hedgehog cactus or simply Lace Cactus (due to the look of the spines). Other names are: Black Lace Cactus, Classen's Cactus, Merry Widow Cactus, Purple Candle Cactus. Etymology: Named after Mrs. Reichenbach.

| Description: Solitary or slowly branching cylindrical shaped cactus with up to 12 branches. It is one of the smaller Echinocereus species.
The Echinocereus reichenbachii species group (E. reichenbachii, E. chisosensis, E. rigidissimus, E. pseudopectinatus, and a number of Mexican species) has unusually thin, bristlelike spines clothing the flowers and fruits as well as conspicuous, cobwebby tomentum of unusually long areolar hairs. The persistent, dry, white features of the flower tube are an essential distinction contrasting with the otherwise similar E. pectinatus species group (E. pectinatus, E. dasyacanthus, and possibly E. bonkerae), regardless of the spectacular, colorful floral displays. |
NOTE: The taxonomic and geographic boundaries among the segregate species or numerous proposed infraspecific taxa of Echinocereus reichenbachii remain nebulous and controversial. In no place do pure populations exist sympatrically, and all taxa appear completely interfertile. Typical E. reichenbachii is endemic to Mexico, near Saltillo, Coahuila. The common plants of E. reichenbachii in Texas, usually lacking central spines, are weakly distinguished from typical E. reichenbachii and are the basis for E. reichenbachii subsp. caespitosus. Oklahoma populations with unusually long bristlelike spines were named E. baileyi Rose [E. reichenbachii subsp. baileyi]. They intergrade, however, with the nearby, short-spined populations of E. reichenbachii. Echinocereus reichenbachii var. albispinus pertains to intermediates between E. baileyi and E. reichenbachii subsp. caespitosus. The flowers of E. reichenbachii var. fitchii are among the largest in the species, and their exact color pattern may prove taxonomically significant. Echinocereus reichenbachii var. albertii is somewhat morphologically and geographically intermediate between var. caespitosus and var. fitchii, but with flowers more closely resembling var. fitchii; it is sometimes considered a synonym of var. fitchii or a variety of E. fitchii Britton & Rose. The name "Echinocereus melanocentrus" appears frequently in cactus literature but has not been validly published. | |
