500 FLORA NIGRITIANA. 
Thonn. Beskr. p. 253.—Senegal to Benin, and over most 
"Tropical regions. 
5. Euphorbia Aypericifolia, Linn.—E. glaucophylla, Poir. Dict. 
Suppl. 2. p. 613?—Cape Palmas, Ansell; St. Thomas, 
Don; a species nearly as common as the last, in Tropical 
countries. 
Two other species of Euphorbia from Guinea, E. lateriflora 
and E. drupifera, are published by Schumacher and Thonning ; 
and two are quoted from Sierra Leone, E. toxicaria, Afz., and 
E. grandifolia, Haw. One or two of the above may be that

by the natives. 
The Anthostema, of Jussieu, is only known from Senegal ;

Brown, as explaining the structure of Euphorbia. 3 
1. Dalechampia ipomweefolia, Benth.; folis cordatis integris 
trilobisve membranaceis subtus ad costas petiolis caulibusque 
pilosulis, stipulis lineari-lanceolatis, involucri foliolis inte- 
gris acuminatis subglabris, stylis apice clavatis.—On the 
Quorra, Vogel. 
Caules scandentes, striatuli, pilis brevibus mollibus plus minus 
vestiti. Stipule anguste, fere semipollicares. Petioli 1-2- 
pollicares, przesertim apice hirsuti. Folia 2}-3} poll. longa, 
2-24 poll. lata, apice acuminata, margine irregulariter sinuato- 
dentata, basi auriculis rotundatis cordata, preter venas fere 
glabra, ad petiolum 5-nervia et in pagina superiore glandulis 
2 linearibus munita, pleraque indivisa, nonnulla irregulariter 
triloba. Pedunculi graciles, folio paullo breviores. Involucri 
foliola membranacea, non colorata, late cordato-ovata, venis 
vix prominulis, basi bistipulata. Flores in capitulo unico 
Juniore vix aperti nec rite examinare potui; stamina tamen et 
styli omnino Dalechampie vidi. 
In the form of the leaves this plant approaches the D. hetero- 
phylla, Poir., from Guiana; but independently of some diffe- 
rences in the flowers, which I was unable very accurately to
