Monographs Details: Clidemia japurensis DC.

Discussion:Examination of the holotype (M) of Leandra heterobasis (DC.) Cogn. has revealed no difference from the C. naevula element of C. japurensis; the Martius collection has definitely predominantly 5-merous non-secund flowers and the shorter dense glandular pubescence of C. japurensis as defined by Gleason. Since the types of neither C. japurensis nor C. naevida have been personally studied, the necessary varietal combination will not be made at present; also the correct generic disposition of this widespread but anomalous species is still unsettled. Incidentally, after study of the Martius holotype (M) of Leandra intermedia (DC.) Cogn., an excellent match for that rare species is de la Cruz 2702 (US), from British Guiana; both the holotype and the recent collection are unfortunately fruiting only, but both have predominantly 5-inerous fruit with an apically sparsely glandular-puberulous ovary.
