Names
THYLACHIUM paradoxum Gilg [family CAPPARACEAE], in E.J. 53: 264 (1915) & in V.E. 3(1): 255, fig. 168 (1915); T.T.C.L.: 121 (1949); DeWolf in Kirkia 2: 197 (1961). Types: Tanganyika, “ opposite Zanzibar I.”, Kirk (K, syn.!) & Lindi District, Kränzlin in Amani H. 2973 (B, syn. !, EA, isosyn.!) & Koerner in Amani H. 2228 (B, syn.!, EA, isosyn.!)
Information
Shrub to about 6 dm. high, glabrous. Branches densely beset with white lenticels. Leaves 1-foliolate; petiole 8–30 cm. long, terete, deeply striate longitudinally; blade oblong to oblong-lanceolate, 9–50 mm. long, 2–4.5 mm. wide, acute or acuminate with a mucronulate apex, coriaceous, with the margin somewhat revolute; midrib impressed above, prominent beneath. Inflorescence a short 5–7-flowered corymbose raceme; pedicels bracteate, 7–8 mm. long. Buds about 1 cm. in diameter prior to rupture. Stamens spreading, wavy, ± 3 cm. long; anthers 2.5–3 mm. long. Ovary ovoid-oblong, 3 mm. long, 2 mm. across, longitudinally striate. Fruits cylindrical, up to 15 cm. long, 7 cm. across, longitudinally 8-ribbed. Fig. 14/5, 6, p. 84.
Range
DISTR. T?6, 8 not known elsewhere
Altitude range
probably below 200 m.
Distribution
TANGANYIKA Lindi District 1944, Gillman 1527 ! & 1 Apr. 1939, Wallace L8 !
Notes
Since all the localized collections definitely come from Lindi District, there may be some doubt as to the accuracy of Kirk’s locality “ opposite Zanzibar Island ” (see Kirkia 2: 197 (1961)). This species differs from T. angustifolium Boj., of Madagascar, in its 1-foliolate, not 3-foliolate, leaves with a very long petiole and short leaflets. The flowers of T. paradoxum seem to be slightly larger and are apparently borne in terminal or pseudo-terminal inflorescences, never on leafless lateral ones. It is known from only five gatherings, three of them made before 1915, but it was collected sterile in 1939 and again in 1944. It would be very interesting to rediscover this plant and investigate, by breeding experiments, its relationship with T. africanum, of which it seems to be an extreme narrow-leaved variant.
