216 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Legume densely ferruginous-pubescent, subterete, more or less stipitate, 
cuspidate at the apex, 10 to 15 cm. long, about 1 cm. broad, the valves narrow 
between the broad, obscurely sulcate margins. 
Founded upon material from Jalapa, State of Veracruz, Mexico, Linden 671, 
of which I have seen no specimens.

NOTES ON OLD SPECIES WITH DESCRIPTIONS OF NEW SUBSPECIES. 
The species of the section form three distinct groups, the types of 
which are respectively Jnga vera Willd., J. edulis Mart., and I. spuria 
Humb. & Bonpl. 
GROUP OF INGA VERA. 
Although Willdenow gives South America as the origin of Inga vera, this 
species seems to be exclusively Antillean, with few related species and subspecies. 
Among the numerous specimens of continental origin attributed to [. vera not 
one has been found that could safely be acknowledged as belonging to this 
species. Inga uraguensis, of the I. spuria group, may represent the nearest 
approach, but it is itself very variable, most of its forms leaning to the I. spuria 
type, with fruits very distinct from those of the West Indian tree. 
The typical J. vera, as described by Willdenow, has glabrous leaves, a char- 
acter which we find to belong only to a few specimens collected in Haiti 
and Jamaica. In other specimens from the same islands the rachis of the 
leaves is distinctly ferruginous-puberulous or pubescent, and the pubescence 
of the calyx, also rusty-colored, is perhaps a little more dense. But all other 
details agree with the corresponding ones in the glabrous form, from which 
these specimens could hardly be separated. This latter facies of the species I 
consider to be Inga vera typica. There are two forms so distinct as to deserve 
subspecific rank. 
Inga vera lamprophylla Pittier, subsp. nov. 
Inga lamprophylla Wright, in herb. 
Young growth, rachis of the leaves, and floral peduncles densely ferruginous- 
pubescent; leaflets, narrow and ending in a long, acute acumen, lustrous above 
and light green or rusty-colored beneath. As these leaflets are not so broad as 
in the typical form, they seem to be farther apart. Moreover, the calyx is 
always stipitate, and often conspicuously so, with the teeth varying in length 
and breadth and the pubescence also ferruginous. 
Type in the U. S. National Herbarium, no. 865550, collected in Haiti, January 
to March, 1871, by Charles Wright (no. 68). 
This subspecies has been collected again by Nash (no. 337) in Haiti and by 
Britton and Cowell (no. 402) in Porto Rico. Specimens intermediate between
