There are several white, tan, or black radial spines and a few brown, black, or reddish central spines on each areole.
22.
The areole was one of the unique features that cacti developed, possibly in adaptation to the ambient climate in the area in which they emerged.
23.
Each circular, hairy areole on the surface of the cactus has a few spines, the longest of which may exceed 2 centimeters in length.
24.
Areoles often have multicellular hairs ( trichomes ) that give the areole a hairy or woolly appearance, sometimes of a distinct color such as yellow or brown.
25.
Each areole has 1 10, round to angular or irregular, 0.1-1.6 mm apothecia that may be confluent when numerous.
26.
In markings and general appearance this species resembles to " Simplicia inflexalis " but with the notable difference that it does not bear a trace of an areole.
27.
Each areole has 3 to 7 main spines which are black to gray or white in color, those occurring near the base of the cactus body reaching up to 3 centimeters long.
28.
Spines are extremely variable, with anywhere from 1-8 per areole, and often absent from lower areoles; they are yellow to white, slightly flattened, and 1 6 cm long.
29.
The shape of the spines separates the varieties : var . " sneedii " has straight spines that spread from the areole and var . " leei " has curved spines.
30.
Vein 7 and 10 from short areole which is formed by the anastomosis of veins 8 and 9 . Hind wings with vein 3 from before end of cell and vein 5 from angle or from above it.
