Names
XYSMALOBIUM Holubii Scott-Elliot [family ASCLEPIADACEAE], in Journ. Bot. 1890, 365 (excluding the Angola plant and description of corona). —K. Schum. in Engl. & Prantl, Pflanzenfam. iv. ii. 232.
Information
Stem 12–18 in. high, with two pubescent lines in the upper part, glabrous below. Leaves sessile or nearly so, 3 1/2–5 in. long, 1–1 1/2 lin. broad, linear, acute, glabrous. Umbels lateral and terminal, the lower pedunculate, the upper sessile or subsessile, hemispherical or subglobose, more than 20-flowered; flowers small; peduncles 1 1/2–5 lin. long, pubescent or with hairy lines like the stem; bracts 2 lin. long, attenuate, acute, subglabrous; pedicels 3–4 lin. long, tapering from the base, puberulous. Sepals reflexed, 1 lin. long, lanceolate acute, concave, glabrous. Corolla closely reflexed; lobes 2 lin. long, 1/2 lin. broad, oblong, acute, glabrous. Coronal-lobes minute, 1/2 lin. long, resembling a small tongue protruding from the hollow at the base of the anthers and directed downwards, narrowly oblong, obtuse, channelled down the face, adnate to the staminal-column, quite free from each other, with no alternating tooth between them. Staminal-column 1/10 in. long; anther-appendages ovate, subacute, inflexed over the apex of the style.
Distribution
Rhodesia Mozamb. Dist. Leshumo Valley, South of the River Zambesi, Holub!
Notes
The preceding species from Angola was confused with this in the original description, and the corona described from the Angolan plant instead of from Holub's specimen; however, it appears best to retain the name for the plant for which it was intended. This species and X. decipiens N. E. Br. are allied to the South African X. involucratum, Decne.
