Two distinct species mixed together have been distributed by Drége and are 
present in E, Meyer's Herbarium under the name B. circinatum, both are probably 
included in the original description, but I take as the type the larger and more 
puberulous plant, because it is the one to which E. Meyer’s label is affixed and of 
which he has dissected a flower, although I can find nothing circinate about the 
latter. This plant I have dissected side by side with Dichelia brachylepis, 
Schlechter, and find them to be identical. The other (B. commixtum, N. E. Br.) 
appears to be a smaller plant and is more glabrous, with darker flowers and a 
different corona. 
32. B. undulatum (N. E. Br.); stem erect, 8-10 in. high, 
branching, puberulous, remotely leafy ; leaves much shorter than 
the internodes, very shortly petiolate, 3-6 lin. long, 14-3 lin. broad 
above the middle, cuneate-ovate, obtuse, with undulate margins ; 
flowers 2-4 together at the nodes ; pedicels scarcely as long as the 
calyx, hairy; sepals 1 lin. long, linear-lanceolate, acute, pilose ; 
corolla cage-like, with the lobes connate at the tips; tube 1} lin. 
long, 1 lin. in diam. at the mouth, campanulate, glabrous ; lobes 
erect, 7 lin. long, linear-filiform, dilated at the apex, sparsely ciliate ; 
outer corona-lobes erect, deeply bifid, with linear subacute segments, 
glabrous ; inner corona-lobes slightly exceeding the outer corona, 
ovate at the base, narrowed to an obtuse apex, incumbent upon the 
backs of the anthers. Dichzlia undulata, Schlechter in Engl. Jahrb.

lin. broad, spathulately or cuneately elliptic, oblong or obovate, 
tapering into a short petiole at the base, obtuse or rounded at the 
apex, much undulated on the margins, glabrous above, minutely 
puberulous with curved hairs beneath ; flowers in pairs or occasion-
