NEW SPECIES, 
Inga goldmanii Pittier, sp. nov. 
A tree 6 to 10 meters high, usually with depressed, spreading crown; branch- 
lets angulate, the younger growth densely rufous-hairy. 
Rachis of the leaves rufous-hairy, winged, 9 to 25 cm. long, the wings 0.8 to 
2 cm. broad, sparsely hairy, the petiolar part (also winged) 2 to 4 cm. long; 
stipules cordate, obtuse, about 1.5 em. long and 1.2 cm, broad, minutely hairy ; 
leaflets 83 or 4-jugate, coriaceous, subsessile; glands sessile, with a supernumer- 
ary one on the costa of each leaflet in the leaves of the seedlings, distinctly 
stipitate, occurring only on the main rachis in the adult leaves; leaflet blades 
oblique, ovate or oblong, rounded and subemarginate at the base, obtuse or acute 
at the apex, sparsely villous and sublustrous above, with the veins and hairy 
costa deeply impressed, dull and glabrous beneath excepting the sparsely hairy 
and strongly prominent venation, the blades of the lower pair 7 to 12 cm. long, 
5 to 6 cm. broad, those of the terminal pair 17 to 20 cm. long, 9 to 11 cm. broad. 
Inflorescences axillary, long-pedunculate, the peduncles densely rufous-hairy ; 
flowers sessile; calyx 14 mm. long. densely fulvous-pubescent without, glabrous 
within; corolla tubular, densely fulvous-tomentose without, glabrous within, 25 
mm. long, the lobes 8 mm. long, narrow, acute; staminal tube included ; pistil 
about 5.5 em. long, the ovary glabrous, the style capillary and searcely thickened 
at the apex. 
Legume flat or spirally twisted, sessile, long-stipitate (the stipe angular, about 
2 cm. long), rounded or subacute at the apex, 20 cm. long or more, 3.5 to 4.8 
cm. broad, densely rufous-hispid, the margin rounded, deeply suleate on the 
sutural line,

Supposed to be very closely related to Inga lindeniana Benth., from Mexico, 
which I have not seen, but the leaflets are oftener 4-jugate, are coriaceous and 
not membranous, and are not hirsute above and velvety beneath. In the 
original description of the Mexican species the calyx is stated to be 5 lines 
(10.6 mm.) long; that is to say, a little shorter than in our species, while in 
the Revision of 1875 the scale has been extended (“5 to 8 lines”), probably so 
as to include the Panama specimens cited. The calyx of J, lindeniana, how- 
ever, is striate and pilosulous, thus a decided departure from that of J. gold- 
manti. Lastly, the pods of the former species are stated to be 1 to 14 inches or 
5 to 6.5 cm. broad, while in the latter they do not exceed 4.5 em. Of the Panama 
specimens cited by Bentham the one collected by Duchassaing is the type of 
the very distinct J. mucuna ; the other may belong under J. goldmanii. 
An interesting feature of J. goldmanii is the presence of supernumerary 
glands or nectaries on the leaflets of the leaves taken from very young trees. 
These extrafloral nectaries are situated on the costa, at a distance of about 2 
cm. from the one on the rachis. It may be mentioned here that the nature and 
functtons of these glandular formations. as especially connected with the genus 
Inga, have never been investigated,
