A TRIBE OF LEGUMINOS RE. | 71 
plus minus sericeum. Legumen 1}-pollicare, minus incurvum quam 
їп D. lunato. 
Hab. Frequent in North Brazil, also British Guiana, Robt. Schomburgk, 
2nd coll. n. 766, Rich. Schomburgk, n. 1495. 
Closely resembles some forms of Macherium leiophyllum ; but the pod 
18 not at all winged. Spruce's specimens, numbered 2552, from the Rio 
Uaupés, have broader leaflets ; and having no pods, it is impossible to say 
whether the plant should be referred as a variety to the Drepanocarpus 
eristacastrensis, or to the Macherium leiophyllum. 
7. D.? rronposus (Mart., Benth. in Ann. Mus. Vind. ii. p. 96, et in 
Mart. Fl. Bras. Leg. ined.), stipulis (parvis) indurato-spinescentibus, 
foliolis sub-7 ovatis oblongisve breviter acuminatis submembranaceis 
reticulato-penniveniis, panicula terminali brevi fusco-pubescente, sta- 
minibus monadelphis. 
Hab. North Brazil, Martius. 
Very near the last species and the Macherium leiophyllum, differing 
from. both in the spinescent stipules. The fruit is unknown; and it 
remains, therefore, uncertain to which genus it should be referred. 
8. D. tnunpatus (Mart., Benth. in Ann. Mus. Vind. ii. p. 96, et in 
Mart. Fl. Bras. Leg. ined.), inermis, foliolis 5-9 (rarius 3) ovatis 
acuminatis coriaceis nitidis tenuissime reticulato-penniveniis, racemis 
axillaribus brevibus confertis, vexillo dense tomentoso, staminibus 
monadelphis.— Frutex volubilis. Foliola glabra, 1-3-pollicaria. Racemi 
fasciculati, vix pollicares. Flores sessiles, 3—4 lin. longi. Legumen 
D. lunati, nisi tomento brevissimo at denso rufescens. 
Hab. Tropical America, North Brazil, and Mattogrosso, Surinam, Wull- 
schnagel, n. 835 ; Cayenne, Martin and others; British Guiana, Rob. 
Schomburgk, lst coll. n. 520, 2nd coll. n. 845, or in some herbaria, 
814, Rich. Schomburgk, n. 1454 ; Venezuela, on the Casiquiare, 
Spruce, n. 3178. 
Doubtful Species. 
D. dubius, H. B. et K., and D. cyathiformis, DC., are not sufficiently 
described to be recognizable. 
D. falcatus, Miq., from Surinam, has, according to specimens trans- 
mitted by him, so exactly the foliage of Drepanocarpus lunatus, with 
detached fruits of Dalbergia inundata, that, unless he has seen specimens 
with the fruits attached, we cannot but conclude there must have been 
some mismatching. 
In Coulter’s Mexican collection there is a flowering specimen with 
numerous small rigid leaves, from Bolaiios, which appears to me to be 
an undescribed Drepanocarpus or Macherium; but without further 
materials, I feel unwilling to attempt to publish it.
