var. albertii
CACTUSPEDIA       

 


Echinocereus reichembachii var. albertii (Black Lace Cactus)
This cactus has large, pretty pink flowers with a very dark center. It's rarity makes it particularly desirable to collectors.
 

Description: Single or branching when old.
Stem: Cylindrical, deep green in color, 3 to 15 cm long, 3 to 5 cm thick;
Ribs: 10 to 13; tuberculate;
Areoles: elliptic, 1.5 mm long, almost touching;
Spines: dark; cental spines 0, or 1, 2 to 3 mm long, purple-
black in color, perpendicular to the stem, or turning slightly upward;
The radial spines and white with dark purple tips spines, number 14 to 20, straight, closely pectinate, 3 to 6 mm long;

Blooming season: Budding and anthesis occur intermittently through the spring and summer.
Fruit: green
Remarks:
The taxonomic and geographic boundaries among the segregate species or infraspecific taxa of Echinocereus reichenbachii remain nebulous and controversial. In no place do pure populations exist sympatrically, and all taxa appear completely interfertile.  
E. reichenbachii var. albertii
is intermediate between E. reichenbachii var. reichenbachii, with a more northern distribution, and E. reichenbachii var. fitchii, with a more southern distribution in the Rio Grande Valley. E. melanocentrus is an invalid name of uncertain application, perhaps referable to E. reichenbachii var. albertii.
 

Cultivation: It is sensitive to overwatering (rot prone) needs a very good drainage to avoid rotting,  but requires more moisture than true desert cacti to grow and produce flowers, Keep drier and cool in winter. Need full sun. It is very cold resistant  from -10 to -25 C (depending on clones) or less for short periods of time. It is a fine plant for a rock garden or container, contrasts well with agaves, yuccas, and low-growing flowering plants.
Propagation:
Seeds, also can be grown from cutting as it slowly branches  from the base;

Family: Cactaceae (Cactus Family)

Scientific name:  Echinocereus reichenbachii var albertii L. Benson

Type: The type specimen (Albert and Benson 1955) is on deposit at Pomona College (POM 317080).

Common Names include: Black lace cactus

Synonyms:

  • Echinocereus reichenbachii subsp. fitchii (Britton & Rose) N. P. Taylor

Origin:  Known populations of the black lace cactus are in Kleberg, Jim Wells, and Refugio counties of south Texas.

Conservation status: Listed in CITES appendix 2.
Currently less than 4000 plants are known in the wild, with several populations being destroyed. The black lace cactus is endangered because its rangeland habitat has been cleared or planted to crops.

Habitat: It is found in in open unshaded grassy areas, and or under heavy brush on south Texas rangeland invaded by mesquite and other shrubs. The local topography is fairly flat, with water standing after heavy rains. The elevation varies from 3 to 60 meter. The climate is semi-arid. Black lace cactus occurs on somewhat saline clay and silt sheets (composed of clay, fine silt sand and gravel)
