SCHOMBURGK'S GUIANA PLANTS. 63 
of being thin and membranous, as described by Kunth from 
the Lonchocarpus Domingensis and latifolius. The L. sericeus 
belongs to Sphinctolobium, and perhaps some other species 
published as Lonchocarpus. In both genera the fruit is in- 
dehiscent, which I have ascertained since I published the three 
species in the former part of this enumeration, and in this 
respect they would both belong to Dalbergiee ; whilst on the 
other hand the complete monadelphous stamens, and -the 
alæ adherent to the wings, connect them with the frutescent 
Tephrosie and other Galegee. 
I had overlooked in my memoir the Semeionotis of Schott 
(Linnea, Litibl. v. VI. p. 55.) which he says is allied to 
Dalbergia and Nissolia. But his character is so imperfect, 
that the genus must yet remain among the doubtful ones. 
The Lonchocarpus pterocarpus, (DC. Prod. II. p. 260), isa 
distinct genus, in which the fruit is membranous as in Platy- 
miscium and Miscolobium, but with the addition of a wing 
along the vexillary suture. I believe it to be the same plant 
to which M. Riedel of Rio Janeiro has given the ms. name 
of Phyllocarpus. 
In a fine set of near 200 Leguminose, gathered by M. P. 
Claussen in the neighbourhood of Caxociras do Campos, near 
the Rio Francisco in the province of Minas Geraes, and com- 
municated to me by Baron B. Delessert, is a second species 
of the curious genus, Cyclolobium, which enables me to com- 
plete, as follows, the generic character. _
