Notes

Brenan (in Kew Bull. 1956: 148 (1956)) considered that a number of specimens from Kenya and Tanganyika represented flowering material of this species and one of his reasons for doing so was that their flowers, which are unusually small for this genus, match the dried-up calyces on the two syntypes of C.clavata, especially in size. A careful re-examination of these reveals, however, that none of these calyx-segments on the synltypes is complete to the apex and therefore their original length is uncertain. It is at least as likely that flowering material is represented by a specimen which has since come to light collected only 60 km. from the type locality at Inhamitanga, in the Manica e Sofala Province of Mozambique (Simão 1202 (K; LM; SRGH), 27.xi.1946). This has bisexual flowers (corresponding male-flowered specimens still remain to be collected). If this be the case the Kenya and Tanganyika material represents a different and probably undescribed species. After re-examination of the situation both Brenan and myself consider that there is room for doubt as to which is the true flowering material of C. clavata and it is very desirable that more good material should be collected in the type locality. A short diagnosis of the flowers of Simão 1202 follows: calyx rotate-campanulate, deeply lobed; tube 1·5–2 mm. long, stellate-puberulous outside, glabrous within; lobes 5 × 2·5 mm., oblong-ovate, apex acute, densely stellate-pubescent outside, with globose papillae within, with c. 7 parallel nerves. Carpels 4–5, densely stellate-tomentose, 2-ovulate; styles c. 1 mm. long, tomentose; stigmas 1 × 1 mm., spreading, papillose; surrounded at the base by 8 sessile anthers. A specimen in bud from Nyasaland (S: Chikwawa, Likabula R., Jackson 1707 (FHO)) also probably belongs here.
