NOTES. — ENGLER & BREHMER (1917) cited seven different collections in their protologue of Trichoscypha abut . One of these, Zenker 3554, the best distributed collection, has been designated as the lectotype.

Trichoscypha oddonii is very closely related to T. acuminata and it may be questioned if these two taxa should be maintained at the species level or wether they might better be treated as varieties. The separation is now based on their leaf characteristics only, as the flowers do not offer reliable elements for specific distinction. In T. acuminata e.g., the disc is quite often hairy, but in T. oddonii the presence of a glabrous disc is not a constant character as a hairy disc has been observed in McPherson 13799, whose leaves at least are clearly T. oddonii . In Cameroun, Equatorial Guinea, and Gabon Amvout or Amvut is the vernacular name for both species ( WILKS & ISSEMBÉ 2000: 94). The local population distinguishes the two based on the tast of their fruits: in T. oddonii they are said to be slightly more acid. Additional fieldwork is needed to determine whether the species can be maintained as distinct.
