specimens have only male flowers and Hiern knew only flowers . = 
sex. But Giircke, who has treated Rhaphidanthe as, so far, a 
typic genus, has attributed to the solitary species, R. obi sinjolia, 
fruits of an oblong-ovoid shape, 15 cm. long. This circumstance 
indicates that Giircke had access to fruiting specimens obtained by 
some collector other than Mann, and the nena! is that these 
fruiting specimens were some collected by Soyaux on the Sibange 
Estate in the Munda district, about 50 miles to the wiih of the locality 
in which Mann’s plant was found; these Soyaux distributed as his 
n. 238. The example of Soyaux, 238, at Kew has been written up 
‘an Rhaphidanthe Hiern MSS ?° and a fruiting twig of this songee 
is here figured (figs. B, 5-9).« The plant of Soyaux is so like that 
Mann that there can be no doubt as to their being congeneric. There 
is, however, considerable doubt as to their being conspecific; the 
leaves of = csibenge plant are much smaller and are uniformly sparingly 
hairy beneath. The characteristic papillae which impart a uniformly 
glaucous specs to the underside of the leaves in Mann’s specimens 
are, in the plant of Soyaux, confined to certain patches of epidermal 
cells ; they are absent from relatively wide areas along the nerves 
and veins, which therefore show up more distinctly. The conclusion 
to which the facts point is that Soyaux n. 238 represents a — 
species, closely allied to R. obliquifolia, based on Mann n. 1800, w 
ay be known as R. Soyauxii, and may be described as follows : _ 
R. Soyauxii, Stapf; species nova R. obliquifoliae aflinis, sed foliis 
minoribus pro longitudine latioribus subtus undique parce pilosis, 
papillis epidermatis ad areas quasdam inter venulas sitas repressis 
facillime distinguenda. 
Arbuscula 2 m. alta, omnino habitu R. obliquifoliae, ramis indumento 
eodem ac in R. obliquifolia. Folia valde obliqua, elliptica, basi eee 
apice rotundata, minute mucronulata, 1-1-5 cm. longa, 0-7-0-8 
lata, tenuiter coriacea, exsiccando supra nigro-fusca, glabra, infra 
paulo pallidiora, praeter nervos venulasque leviter pruinosa, undique 
pilis sparsis adpressis conspersa, costa et interdum nervis lateralibus 
basalibus supra levissime impressis ; petiolus vix 1 mm. longus. 
8 ignoti. i i i 
apiculati, circiter 2 cm. longi, 1 cm. diametro, an 3-loculares, pericarpio 
exsiccato crustaceo verruculoso praeter apicem summum subtomen- 
tosum pilis parce consperso. Semina ellipsoidea, uno latere explanata, 
12 mm. longa, 7 mm. lata, testa tenui atro-brunnea in latere convexa 
endosperma amplum, subosseum, album. Embryo rectus, semine 
paulo brevior ; cotyledones foliaceae, ovatae, quam radic ul 
longiores
