Euphorbia decidua P.R.O.Bally & L.C.Leach

국표에 없다.

Origin and Habitat: Angola, Zimbabwe, Zambia, Malawi and Zaire.
Habitat: Grows in deep sand and cracks among granite rocks.
Specially protected in Zimbabwe. The species will disapper as a result of agricultural development and building (Lilongwe, Malawi). A seedling showing the characteristic leaf-bearing juvenile stage is possibly confused with a seedling of Haemanthus sp.

Synonyms:

Description: It is a dwarf and very slow growing spiny perennial succulent with a large 'turnip-like' woody tuberous root.
Stem: Subterranean (in habitat) or usually above ground in cultivation, much reduced, merging imperceptibly with the root and forming a spherical to conical woody caudex 5-10 cm in diameter and 5-20 cm tall. The small central apex on the enlarged woodstock produce in spring numerous thin deciduous branchlets to form a small clump up to 30 cm in diameter. The branchlets are green erect, 7–20 cm long, 3-5 angled, about 5-6 mm in diameter;
Spines: 3–4 mm long, widely divergent, with expanded bases.
Leaves: In juvenile stage the thick, subterranean stem bears broad apical, ovate, sessile, deciduous leaves 12- 22 mm long. But at maturity the plant produces only a small showing of deciduous green spiny stems. (Production of independant, sometimes floating leaves from the base of the spiny branches seems to be of somewhat sporadic occurrence.)
Flowers: Pale green with a red centre.
