A TRIBE OF LEGUMINOSA. 28 
usually five leaflets ; the name was therefore very inappropriate, 
and the species, а very common one, is so well known under 
Willdenow's and Roxburgh's name of uliginosa, that I have pre- 
ferred the latter, although not of so old a date. 
Pongamia was established by Ventenat for the Robinia mitis of 
Linnæus, or Galedupa indica of Lamarck, the name of Galedupa, 
although older, being suppressed, as the plant proved not to be 
the Caju- Galedupa of Rumphius, as was at first supposed. Several 
species have since been added, but they all belong either to Derris 
or to Millettia, and Pongamia glabra again remains alone, unless it 
be united with Lonchocarpus and Derris, in which case Loureiro’s 
name, being the oldest, would have to be adopted for the whole 
group, and Lonchocarpus and Pongamia would be reduced to 
sections. 
_Piscidia is a Linnean genus consisting of a single species, re- 
markable for the four broad longitudinal wings of the pod, which 
are lateral expansions of the sutures. Linnæus did, indeed, distin- 
guish two species, one with continuous wings, the other with the 
Wings here and there interrupted between the seeds; but these 
interruptions have since been shown to be owing only to the 
accidental abortion of ovules, and consequent non-development of 
the corresponding portions of the pod, and to be very inconstant 
inthe same specimens. In flower it is sometimes difficult to dis 
stinguish the plant from some specimens of Lonchocarpus guate- 
malensis. The plants, since referred to Piscidia, are chiefly species 
of Sesbania, in which the pods are similarly four-winged. 
Millera of Linneus was again founded on a single species on 
account of its remarkable pod, which, in its more perfect state, 
resembles a string of large beads. Not uncommon in Cayenne, it 
à given rise to much confusion in synonymy. Aublet, not having 
identified it with Linnzus' character, published it under the name 
of Ooublandia ; and again (having a loose fruit, reduced by abortion 
to à single seed, and which then is nearly globular), he figured 
ìt as the pod of his Deguelia, his flowering specimens of Deguelia 
being those of of my Derris guianensis (Lonchocarpus pterocarpus, 
DC. Miquel, having at first seen specimens in flower only, struck 
With their close resemblance to those of Sphinctolobium virgilioides, 
Vog., described them as a new Sphinctolobium, till the receipt of 
iting specimens enabled him to recognize Linnsus' Müllera, and 
he was then led to conclude that even Vogel's Sphinctolobiums might 
reduceable to ега. Their fruits are, however, all flat, and 
Miillera may be kept up for those species of which the thick fruit
