8. BASEONEMA, Schlechter & Rendle in Journ. Bot. 1896, 97. 
Calyx-lobes 5. Corolla 5-lobed almost to the base, reflexed ; lobes 
linear-oblong. Corona none. Stamens 5, inserted at the base of the 
corolla-lobes and alternating with them ; tilaments free, broadly dilated, 
thick, fleshy and contiguous at the base, filiform above; anthers erect, 
linear-oblong, acute, adnate in their lower part to the dilated apex ot 
the style and connivent over it in an obtuse cone, cohering at their 
tips, glabrous. Within the stamens and alternating with them are 5 
minute free rounded lobules. Style rather slender in the lower part, 
abruptly dilated into a stout fleshy conical mass at the apex, obtuse, 
Shorter than the anthers. Pollen granular. Follicles not seen.— 
Apparently a shrub. Leaves opposite, petiolate. Flowers small, in 
dichotomous or trichotomous cymes. 
Endemic, monotypic. 
This genus only differs from Tacazzea in being entirely destitute of a corona; in 
all other characters it is identical with that genus. 
1, B. Gregorii, Schlechter d: Rendle in Journ. Bot. 1896, 97, &. 356, 
fig. B. Apparently a woody plant, with long straight branches, sub- 
glabrous or slightly puberulous ; internodes up to 5 in. long. Leaves 
opposite, spreading ; petiole 34-5 lin. long ; blade 1}-2} in. in length 
and breadth, nearly circular, very shortly and obtusely apiculate, cordate 
at the base, very shortly velvety-pubescent on both sides, but more 
Sparsely above. Cymes pedunculate, dichotomous or trichotomous, 
glabrous ; peduncle 6-13 lin. long; branches 2-33 in. long, spreading, 
several-flowered ; pedicels }-1 in. long, rather slender, glabrous, 
except at the apex, which is rather densely pubescent and thickened 
under the calyx ; bracts about }—? lin. long, narrowly oblong, obtuse, 
densely pubescent with short spreading hairs. Sepals 4-2 lin. long, 
4-4 lin. broad, ovate, obtuse, densely pubescent, recurved. Corolla 
reflexed, lobed almost to the base; lobes 34-3 lin. long, 14-1} lin. 
broad, linear-oblong, obtuse, narrowly reflexed along the margins, 
tomentose on the back, glabrous, on the inner face minutely ciliate on 
One margin. Corona none. Filaments of the stamens 1 lin. long, 
dilated at their basal third into a broad semicircular fleshy mass, above 
which they are filiform; anthers about 1} lin. long, linear-oblong, 
acute, adhering to the dilated apex of the style, connate at the tips.—
