Notes
Robson (F.Z. 2: 236 (1963)) states “the number of carpels in our area [F.Z.] is apparently always 5. In a closely related species of fringing forest and rain-forest margins in Morogoro District, Tanzania, however, it varies from 6–10 and specimens of O. macrocalyx from that area sometimes have 6–8”. Vollesen in Opera Bot. 59: 25 (1980) mentions O. sp. nov. aff. O. macrocalyx which differs in habit and in the larger number of carpels but is otherwise very close. He cites Carmichael 147, Burtt 5405, MRC 537 and Vollesen MRC 4062. I have been unable to sort out this variable assemblage and am treating all as O. macrocalyx. Dr. Wadhwa during preliminary studies had reached the same conclusion. Doubt remains and field studies on correlation of habit and carpel number with habitat are needed.The K 7 indication above is based on Luke & Mbinda 5847 from Kwale District: Shimoni collected in coral rag forest at 10 m on 11 May 1999. It is a tree to 5 m with rather thinner leaves with rather more rounded base and more slender pedicels; the bright red fruiting sepals are up to 3 x 1.5 cm. Further flowering material is needed to confirm its identity (see also after O. insculpta).
