Xerophyte

Habit

It is a slow-growing, spherical, perennial succulent, either solitary or forming groups of about 10 or more stems.

Central Spines

Central spines are usually not formed. Rarely are one or two available.

Seeds

Brown, shining, broader at apex than below.

Description

Coryphantha pseudoradiansSN|10262]]SN|10263]], usually without central spines, is a local or morphological form of Coryphantha pallidaSN|10263]]SN|10262]] that characteristically has 3 central spines. This two taxa are linked one to each other by plants with central spine variable in number from 0 to 3 found in Tejupan. The otherwise identical features of C. pseudoradians and C. pallida, namely size and form of stems, radial spines, flowers, fruit, etc., prove, that is impossible to differentiate between these taxa.

Tubercles

Close set, short, thick and rhomboid at the base in 13 rows, , up to 10 mm long. Axils at first woolly, becoming bare.

Flowers

Pale lemon yellow very large, often 6-7 cm long and in diameter.

Stem

Globose to obovate, short and thick, closely set, glaucous-grey-green, 8-12 cm in diameter.

Radial Spines

13-20, slightly bent, flattened against the stem surface, yellowish to brownish, up to 1 centimetre.

Fruits

Greenish brown, to 20 mm long.
