FLORA NIGRITIANA. 499 
on the sandy shores from Senegal to Benin, Don, Vogel and 
others ; and extending south of the Line, Curror. 
The leaves are more frequently blunt than pointed: in every 
other respect, Thonning’s description is very accurate. 
3. Euphorbia (Anisophyllum) convolvuloides, Hochst. in Kotsch. 
Pl. Nub. Exs. n. 242; herbacea, stipulata, prostrata, ramis 
villosis, foliis oppositis sessilibus ovatis oblongisve basi valde 
obliquis crassiusculis supra viridibus parce pilosis subtus 
appresse tomentosis, floribus in capitula axillaria ` sessilia 
nune in ramulos breves foliatos abeuntia confertis, involucri 
dentibus exterioribus orbieulato-reniformibus parvis, capsula 
dense tomentosa, seminibus subtetragonis transverse rugosis. 
—Ün the Quorra, at Attah, Vogel; at the Confluence, 
Ansell, 
Habitu E. pilulifere accedit, foliorum consistentia et indumento 
facile distincta. ^ Folia 4-1 poll. longa, 3-4 lin. lata, margine 
interdum obscure denticulata, basi valde ineequalia et oblique 
truncata v. subcordata; pagina superior oculo nudo glabra 
videtur, sub lente pili appressi sparsi apparent, pagina in- 
ferior tomento arcte appresso canescit v. rubescit. Flores 
nune in capitulum densum subaphyllum dispositi, nune ad 
axillas foliorum plus minus evolutorum sessiles, spicas for- 
mant unilaterales foliatas ad axillam folii majoris. — nvolucra 
semilineam longa, dense tomentosa, dentibus exterioribus 
nune fere obsoletis v. quam glandulz interiores brevioribus, 
nune eas duplo triplove superantibus subpetaloideis albis v. 
rübentibus. Capsula quam in E. Chamesyce paullo major, 
obtusangula, tomento albido v. rubescente dense vestita. — 
lam not aware that Hochstetter's name has been otherwise 
Published than on Kotschy’s labels. In order, however, to 
avoid confusion, I adopt it ; although the fancied resemblance to 
a Convolvulus does not strike me. In Ansell’s specimens the 
flowers are all capitate ; in Kotschy's they are arranged in leafy, 
axillary spikes; in Vogel’s, both inflorescences may be seen on 
the same stem.
