  Echinocereus chloranthus
var. cylindricus "corellii"
(Echinocereus viridiflorus var. corellii)
CACTUSPEDIA       

 


Echinocereus chloranthus v. cylindricus "corellii"
SB743 Marathon, Brewster County, Texas, USA
Nice plant with Shiny yellowish spines and brown yellowish flowers.
 

Description: Usually grows singly or forms two or more stems , but never forms large clusters or mounds.
Stems: as much as 7,5 cm in diameter and 15 (25) cm tall.
Spines: This species has short shiny yellowish spines but show a considerable variability in spine shape, some plants has only radials while other have a variable number of short centrals.
Flowers: Smaller than others in this genus about 2,5 cm long and 2,5 cm inch broad.
Brown yellowish, and grow well down on the sides, often forming a band around the middle. Blooms in March or April.
Fruit: The fruit is small about the size of a small grape, green at first and later turning a purplish red and spiny.
Remarks: E. chloranthus is part of the E. viridiflorus compless that comprises a large number of infraspecific taxa, differing in various combinations of flower color, spine color, number and thickness of central spines, and other characters, including floral scent. Wherever such taxa are sympatric they intergrade; all are freely interfertile in the greenhouse. Among them:

Recognized subspecies, varieties and forms:
  • E. viridiflorus var. viridiflorus: (Typical form) With small stems and relatively pure yellow flowers, extends from central New Mexico and the Texas Panhandle to South Dakota. (E. viridiflorus var. robustior) is a more robust form but not sufficiently differentiated and considered merely  a local variant of  E. viridiflorus v. viridiflorus.
  • E. viridiflorus var. chloranthus (E. chloranthus) with the most numerous central spines (five or more per areole), giving the plants a bristly appearance, are often considered a separate species.
  • E. viridiflorus var. russanthus (E. russanthus) : Plants with a bristly appearance usually with reddish or russet flowers. Yellow-spined plants may occur at high altitudes.
  • E. viridiflorus var. cylindricus (E. chloranthus var. Cylindricus) : The common morphotype at middle altitudes in Texas and southeastern New Mexico has 0-2(-3) central spines.
  • E. viridiflorus var. correllii  (E. chloranthus var. Cylindricus "corellii") A poorly defined, yellow-spined population near Marathon, Texas.
  • E. viridiflorus var. neocapillus (E. chloranthus var. neocapillus): Remarkable for its softly hairy, not sharply spiny, seedlings.
  • E. chloranthus subsp. rhyolithensis Bristly red-spined plants from New Mexico.
    NB: Echinocereus viridiflorus in the broad sense may prove paraphyletic with respect to E. davisii, but they are phenologically isolated, with E. davisii flowering earlier and thus appearing reproductively isolated in the wild.

 


 

 

The flowers are tiny greenish with rusty-red midlines, greenish-yellow anthers,
and have a very spiny calyx.
Flowering March June.

Cultivation: Rot easily it is sensitive to overwatering (rot prone) needs a very good drainage to avoid rotting, Keep drier and cool in winter. Need full sun. Cold resistant  above approx - 12C or less for short periods of time.

Propagation:
 It can be grown from seeds.
