Pachypodium rosulatum subsp. cactipes (K.Schum.) Lüthy

DESCRIPTION:  Shrub-like up to 1 m high, diameter up to 1.50 m, with a squat pachycaul trunk (inflated base). Caudex: Spineless, strongly succulent to subglobose and (at least apically) spiny that turns silver grey as it ages. After the plant first flowers, it begins to branch until it forms a head of short, thick, tapered branches with groups of leaves sprouting from the tips of the branches. Young stems more or less erect. Leaves: The leaves, which fall in the dry season, form a rosette on the top of branches. They are deciduous, very dark green above, white below, margins revolute. Spines: Weak, needle-like, reddish, conical on the upper half of the plant. Flowers: Open-faced, canary yellow, at the end of long pedunculate inflorescences, with rather short and wide tubes and hairy ovary. Corolla pale yellow outside, bright yellow inside.
