The genus Phzoneuron, founded by Gilg on a tropical 
W. African plant closely allied to Dicellandra, has, together 
with other allied Melastomacee from the same region, been 
studied by Dr. Stapf, with the result that the generic 
characters of the first-named genus must be modified, and 
both enlarged by characters afforded by their seeds. In 
anticipation of a paper on the subject which he proposes 
to publish, he has given me the following diagnoses of 
both genera, with a list of the species appertaiing to 
each:— 
DicEtuanpRa, Hk. f. Stem 4-angled. Calyx 5-toothed. Stamens in 2 
sets differing in oe and size; lenat appendages of connective mag 
pointed. Seeds obovoid, a pendaged at the upper posticous end ; sve ~ 
brittle, granular anticously above; raphe hollow walls, thin. FE ak 
ovoid, placed beneath the granular portion of the testa. D. Barteri, Hk. f, 
Fernando Po. 5 Il alik 
Paxonevron, Gilg. Stem terete. Calyx entire. ie oral Pacey e, rie 
nearly so; basal appendages of connective short, tips thicken aa 8 
cuneiform ; testa smooth; rhaphe large, spongy OF. corky. moryo 8u 
cylindric, occupying the whole anticous side of the seed.
