glabrous, have their axils 14 in. apart, and bear at their summits a terminal raceme; 
leaves 14 in. long, 9 lines broad, on hirsute petioles 1 line long, opposite upon the short 
secondary branchlets, which are 6 lines apart ; raceme spreading, consisting of 3 branches, 
nearly 3 in. long, all issuing from the base, where they are bare for 1 in., bearing upwards 
at intervals of 6 lines lateral branchlets 8 lines long, bare for half that length, which bear 
upwards a mass of approximate flowers more or less spreading, and all hirsutulous; 
pedicels 1 line long; sepals $ line long; corolla 2 lines long, with an extremely short 
tube ; follicles said to be more than 1 foot long.

In Antillis : v. s. in herb. Mus. Brit. Hispaniola (Swartz). 
This specimen agrees with Poiret's description: its leaves are opposite, obovate, sub- 
euneately narrowed towards the base, rounded, mucronate at the shortly narrowed 
summit, of a laurel-like texture, very dark green above, glabrous, rigidly coriaceous, 
suleate along the midrib and 5 pairs of divergent slender yellow nerves, nitid, with a 
thick corrugulate parenchyma, pale yellow and opake beneath, granular and sparsely 
puberulous, with prominent midrib and nerves, the veins wholly immersed, 14-14 in. 
long, 9-10 lines broad, on slender channelled petioles 3 lines long; panicles axillary, 
longer than the leaves, puberulous, much branched, branches 6 lines long, again sub- 
divided, with very numerous small flowers on bracteolate pedicels 1 line long; sepals 
subobtusely ovate, puberulous, + line long; corolla in bud 2 lines long, shortly puberu- 
lous; tube very short; rest as in the preceding species. 
15. ForsTERONIA ROTUNDIUSCULA, nob. In Brasilia: v. s. in herb. Mus. Brit. in fructu (Sellow). 
A species very near the preceding: branches slender, terete, glabrous, dichotomous, 
axils about 1 in. apart; leaves orbicular, sometimes plicate, slightly cordate at the 
base, suddenly constricted at the apex into a short acute acumen, fuscous green above, 
finely rugulose, with immersed very fine nerves, paler and brownish beneath, opake, 
obsoletely puberulous, with prominulent fine nerves, 14 in. long, 11 in. broad, on slender 
petioles 1 line long ; inflorescence axillary; fructiferous peduncle 9 lines long; glabrous 
follicles 2, terete, 5 in. long, 1 line broad, much arched and conjoined at the apex ; seeds . 
many, linear-oblong, 4 lines long, compressed, striated dorsally, with a white longitudinal 
raphe along the ventral face; coma reddish, sericeous, 6 lines long, suberect, and 
eaducous. 
LASEGUEA. 
A very good genus, established in 1844 by Prof. De Candolle, well illustrated by 
Delessert in his *Ieones, and by Dr. Müller in the * Flora Brasiliensis, as well as by 
Velloz in the * Flora Fluminensis.’ Its several species have frequently (perhaps always ?) 
knotty tuberose roots, from which spring one or more simple, stoutish, erect, sub- 
herbaceous stems, with axils not very remote; the leaves are opposite, ovate or oblong, 
often cordate, on stoutish petioles; raceme lateral or subterminal, forming an elongated
