This is very closely related to C. atrovirens, Pax and more 
ceevae _ the form of C. atrovirens which has been distinguished 
er the name C. inaequilaterum. As a rule the leaves 
differ metals: in shape and are much more sparingly pubescent 
but in some of the gatherings the leaves of the two much resemble 
each other. ‘The female flowers of C. atrovirens and C. oleraceum 
are not distinguishable but the fruit of C. oleraceum is smaller and 
more deeply depressed between the cocci than is the case in 
C. atrovirens while the seeds in our plant are more deeply reti- 
culated than those of its near ally. CC. Barteri Hook. f. 
africanum, Muell.-Arg.), to which this species has hitherto been 
referred, differs in having a much shorter style with subglobose and 
papillose stigmas and in having a shallow urceolate hypogynous 
disk, slightly 5-lobed in fruit. Its leaves also are smaller and are 
thinly membranous even when quite mature. We are indebted to 
the kindness of Dr. Engler and of Dr. De Wildeman for an 
opportunity of studying the extensive series of specimens of this 
species which are preserved in the Berlin and the Brussels herbaria. 
From the field notes accompanying many of the specimens collected 
in the Congo State it would appear that throughout the area in 
which it occurs the leaves of this plant are generally used as a 
vegetable. In monographing the genus Claoxylon it will be found 
desirable to transfer the section Athroandra to the allied genus 
Erythrococca, Benth.
