Names
Hyalosepalum tenerum Miers Troupin [family MENISPERMACEAE], in Bull. Jard. Bot. Brux. 19: 431 (1949). Type as above. Tinospora tenera Miers [family MENISPERMACEAE], Contr. Bot. 3: 37 (1871). — Troupin, F.T.E.A. Menisperm.: 20 (1956). TAB. 21 fig. D. Type: Mozambique, lower Shire Valley, Kirk (K). Desmonema tenerum Miers Diels [family MENISPERMACEAE], in Engl., Pflanzenr. IV, 94: 154 (1910). — Brenan, T.T.C.L.: 327 (1949). Type as above.
Information
Liane with yellow-brown glabrous branchlets. Leaf-lamina 4–7 x 2.5–6 cm., broadly ovate to suborbicular, cordate or obtuse at the base, acuminate, apiculate and sometimes mucronulate at the apex, glabrous on both sides, papery, pale green, nerves 5, palmate, petiole 2–3.5 cm. long, glabrous. Male inflorescences 10–35 cm. long; pedicels 2–3 mm. long. Male flowers with oblong-obovate outer sepals 0.5–1 x 0.4–3.7 mm.; inner sepals 1–1.5 mm. long, obovate-spathulate; petals 1–1.5 mm. long, keeled; stamens 6, their filaments 1–1.5 mm. long, connate to half-way up. Female inflorescences, female flowers and fruits unknown.
Habitat
Lowland rain-forests.
Altitude range
Lowland 100 0 inferred from lowland
Distribution
Mozambique M Lourenco Marques, fl. 9.xii.1897, Schlechter 11675 (BM; K).Mozambique MS Chizombero, fr. 14.iii.1948, Garcia in Mendonça 608 (BM; LISC).Mozambique T Lower Shire Valley, fl. 3.i.1862, Kirk (K).Mozambique Z Quelimane, Stuhlmann 742 (B).Zambia S Mapanza E. fl. 6.xii.1953, Robinson 390 (K).
Distribution (external)
Tanganyika Transvaal
Notes
Chase 1381, (S. Rhodesia (E), Hot Springs, Melsetter, fr. 29.xii.1948) may also belong to this species. The leaves of this specimen are truncate or only very slightly cordate, and so resemble T. tenera rather than T. caffra. However, male flowers will have to be obtained before T. tenera can be recorded with certainty from S. Rhodesia.
