Description

C.pubescens can be identified by the globular petal appendages of its flowers. Those of Crassula pubescens subsp. pubescens are oval Crassula pubescens var pubescens - flowers detail 3 - Copy.jpg

A small (up to 40 cm), shrubby perennial, with delicate, erect stems and pubescent (velvety) leaves that are 1-3 cm long.

The peduncle emerges above the leaves of the rosette. The peduncle is 3-15 cm long, with one or two bract-pairs (not 15-40 cm long with 2-5 bract pairs like those of Crassula subacaulis ). The tips of its 2-3mm long petals are roughly twice as long as they are broad, and have rounded appendages (not beaked/rostrate like those of Crassula atropurpurea ).

Subspecies

Crassula pubescens subsp. pubescens has erect branches, pubescent (velvety) leaves and petal appendages that are elongated-oval Crassula pubescens var pubescens - Robertson - Copy.jpg

This species is variable, and several subspecies exist, which differ in their core features:

C. pubescens is closely related to the similar species Crassula subaphylla (which has longer petals - 3,5-4,5 mm), Crassula cultrata , Crassula cotyledonis , Crassula atropurpurea and Crassula nudicaulis . [1]

C.pubescens is much smaller than Crassula cultrata (which has a distinguishing spike inflorescence and leaves that are usually longer than 3 cm).

Distribution

It occurs from the Cedarberg area in the west, throughout the Little Karoo, into the Eastern Cape Province. It is recorded from the Worcester and De Doorns areas, from Napkys, Riversdale, Gouritz, Montagu, Laingsburg, Ladismith, Vanwyksdorp, Uniondale and Mossel Bay. [2]

Cadaba aphylla is one of some 30 species in the genus Cadaba. It grows as a straggly, perennial shrub or small tree, virgate, much-branched, dark green, often with purple bloom, and usually leafless, and may reach 2 m in height. Its branches are somewhat succulent and frequently spine-tipped. Leaves of some 10 x 2 mm are found on seedlings and young branchlets. Its deep red flowers in axillary clusters have prominently exserted stamens, making this a colourful plant in summer. Fruits are some 90 mm in length, green at first, turning a rusty brown when mature, and covered in sticky hairs. A sticky orange pulp covers the small black seeds. This species may occur in dry bushveld or semidesert conditions from tropical Africa to Namibia, Zimbabwe, Botswana, and South Africa.

Sepals 4, yellow or reddish-purple, 1–1.7 x 0.7–1 cm., the lowest rather larger than the remainder, connate at the base into a very shallow receptacle c. 1 mm. in depth, broadly elliptic, obtuse at the apex, with capitate, glandular hairs densely or sparsely scattered on both sides. Petals 0. Androgynophore 2.5–3 mm. long, glabrous, shallowly declinate with a hooded nectary at its base c. 4 mm. broad. Stamens 8; filaments 1 cm. long; anthers 2.3 x 0.75 mm., oblong.
