First Description by Kimnach & Uhl in Cactus and Succulent Journal US 55(1): 27-30. 1983 :

 

Plant papillose in all parts except androecium and gynoecium.

 

Roots fibrous.

 

Stems to 8 cm long or more, 8 - 12 mm thick, nearly lacking papillae.

 

Rosettes proliferous, to 18 or more, rather diffuse, 5 - 10 cm wide, 2 - 3 cm high, with 15 - 25 leaves.

 

Leaves obovate-oblanceolate, subobtuse, mucronate, 2.5 - 3.5 cm long, the mucro acute, 1 - 3 mm long, often curved to one side, the shoulders of the leaf-apex often unequal, 10 - 16 mm wide at the widest part (ca 3/4 above base), 8 - 10 mm wide at base, ca 5 mm thick at widest part, ca 3 mm thick near base, ± concave in apical third, flat to somewhat convex below, the lower surface obtusely keeled, more acutely keeled toward apex, the epidermis green, somewhat reddened along margins and at apex, the papillae minute and hemispherical on upper and lower leaf-surfaces, forming oblong, obtuse cilia in several parallel rows along margins, largest near leaf-apex, colorless to red.

 

Flowering stems to five or more, suberect, equilaterally racemose or often with the lower flowers in two's 10 - 12 cm long, the peduncle 6 - 8 cm long, the lower 1 - 3 cm without leaves, 4 - 7 mm thick, moderately papillose, strongly reddened, the leaves 12 - 18, their points of attachment ca 5 - 7 mm apart, ascending, more rarely spreading, shaped like the rosette-leaves, 1.5 - 2.5 cm long, 10 - 13 mm wide, green, rather loosely attached and with a gibbous to divergent, semi-clasping, obtuse or sometimes sub-acute basal spur; inflorescence densely sub-capitate in bud or in early flowering, later 4 - 9 cm long, 7 - 20 - flowered, branches 2 - 6, ascending, 4 - 25 mm long, 2 - 3 mm thick, smooth and shiny, nearly epapillose, reddened, each branch with 1 - 3 bracteoles that are 8 - 14 mm long, 3 - 7 mm wide, 2 - 3 mm thick, papillose, ciliate, green.

 

Flowers : Sepals united at base for 1.5 - 2 mm, ascending, ovate-elliptical, acute, somewhat unequal, 5 - 8 mm long, 2 - 3 mm wide, 1.5 - 2 mm thick, heavily papillose, ciliate, green, or often reddish, becoming thickened (to 4 mm) after flowers dry, corolla campanulate-globose, 8 - 10 mm long, 6 - 8 mm thick, the limb 5 - 8 mm wide, the petals united at base for less than 1 mm, ovate-elliptical, acute, subapiculate with the apices recurving slightly in some clones, sub-erect in others, 2.5 - 3.5 mm wide, more or less distinctly keeled on back, reddish orange and heavily papillose on outer surface, yellow and epapillose within, gibbously swollen inside near base on each side ......
