588 ‘NOTES ON MIMOSE. 
I. Bourgoni sed longius pedunculate. Corolla vix 2 lim 
longa.— Brasil, at Gongo-soco, Riedel. 
31. I. marginata (Willd. Spec. 4. p. 1015), ramis foliisque 
glabris, petiolo sub foliis anguste et longiuscule alato, foliolis 
bijugis elliptico-oblongis acuminatis nitidis, spicis elongatis 
laxis, calyce corolla pluries breviore, tubo stamineo subex- 
serto, * legumine lineari nodoso."—Mimosa fagifolia Linn. 
Spec. p. 1498.—Foliola suprema 3-4-pollicaria. Spice tri- 
pollicares. Bracteæ minute, ovate, cuspidatæ.—Caraccas, 
Bredemeyer, British Guiana, Schomburgk, 2nd. Coll. n. 918 
(1443).—The consistence of the leaves and inflorescence of 
this plant bring it much nearer to I. laurina than to I. Bour- 
goni to which it is usually referred, it is also near I. semia- 
lata; but the wings of the petiole are longer and narrower, 
the leaves shorter and firmer, the bracts shorter and broader, 
and the pod (which I have not seen) is very differently 
described. Kunth’s I. marginata, considered by De Candolle 
as distinct, is said by others to be the true I. marginata, 
Wilid., but as neither flowers nor fruit have been seen, it 
cannot at any rate be admitted as a separate species.
