MR. G. BENTHAM ON THE GENERA SWEETIA AND GLYCINE. 263 
9. S. PANAMENSIS, sp.n. Glabra vel tenuissime puberula, foliolis 5-11 
ovatis vel ovali-oblongis rigidulis nitidis tenuiter venulosis, racemis 
laxiuseulis puberulis, legumine tenui glabro.—Foliola 1-2-pollicaria. 
Hab. Paraiso station, Panama railroad, Sutton, Hayes. 
This species has the foliage nearly of S. nitens, with the fruit of 
S. elegans. 
10. S. GARDNERI, sp. n. Glaberrima, foliolis 3 ovatis vel emer 
oblongis breviter acuminatis tenuiter coriaceis nitidis venosissimis, 
racemis laxis breviter paniculatjs.—Foliola nunc 1}-2-pollicaria, nune 
duplo fere majora. Racemi numerosi, panicula tamen foliis brevior. 
Alabastra ut in speciebus 2 pracedentibus fere globosa, calyce basi 
brevissime tantum attenuato. Petala inter se subzequalia. Legumen 
ignotum. 
Hab. Prov. Pernambuco, Gardner, n. 962. 
Leptolobium tenuifolium, Vog. in Linnea, xi. 391, which I have 
not seen, appears to me to be very doubtful. It is described as 
differing from the others in its membranous leaves and broader 
petals, It was gathered by Sello between Campos and Victoria. 
Leptolobium ? leiocarpum, Vog. in Linnea, xi. 393, described from 
fruiting specimens only, and therefore left doubtful, proves to be 
the fruiting state of Apuleia precoa, Mart. 
Leptolobium ? punctatum, Benth. in Linnza, xxii. 526, described 
from indifferent specimens in flower only, is Myrocarpus fron- 
dosus, Allem., a distinct genus, but of which the position in the 
system, either next Sweetia in Sophorex, or as an anomalous 
Cesalpiniea, is as yet doubtful. The flowers are too fully out to 
ascertain the estivation, especially as the petals are exceedingly 
narrow linear. : 
The genus Leptolobium or Leptocyamus, which I had proposed, 
is reducible to Glycine, Linn., as now most conveniently limited. 
Up to the time of DeCandolle's ‘ Prodromus, the genera Glycine 
aud Dolichos had become receptacles for all Phaseolee which had 
no very striking character to distinguish them. DeCandolle, in 
reforming the order, eliminated most of the anomalous species 
Which had been referred to Glycine for want of a better place, and 
established a somewhat better-characterized group of small-flow- 
ered slender Phaseolew, distinguished from Galactia chiefly by the 
calyx. He still retained, however, two distinct types, afterwards 
well separated by Arnott (in Wight and Arn. Fl. Penins. Ind. 
Or.)—one with the alternate stamens abortive and a remarkably
