Xerophyte

Habit

Plants solitary.

Central Spines

1-3(-4), rigid, to 20 mm long (or more) somewhat curved upward, grey or, especially in young plants, two coloured.

Description

Coryphantha georgiiSN|10211]]SN|10210]] is a small rare species with pale creamy-yellow to pure white flowers.

Roots

Taproot.

Juvenile Spines

Juvenile specimens have only 6 horizontally radiating radials, upper radials and central spines often with a sudden change of colour from brown to a chalky-white tip.

Tubercles

Loosely arranged in 5/8, 8/13 or 13/21 series, large, somewhat bulgy, conical, rounded and not keeled below, to 12 mm long, axils with wool and large orange-red nectar glands.

Flowers

Cream or white with pale green throats, 2-4 cm long and in diameter.

Stem

Flattened globose to clavate, to 4 (or more) cm high and 7 cm in diameter, covered by spines, with woolly stem tips. Epidermis dark glossy green. The more clavate forms, which were described by Backeberg in 1942 as Coryphantha villarensisSN|10210]]SN|10211]], grow throughout the whole range of distribution, mainly in the shade, especially under bushes. Globular and clavate forms are only the result of the micro-location (more or less sun).

Radial Spines

8-9, needle-like, all the same length, greyish white with dark tips, to 12 mm long. Lower ones regularly and horizontally disposed, upper ones very close or bundled.
