and veins pubescent on both faces and very prominent on the inferior one, 
the blades of the basal pair 4.5 to 8 cm. long, 2 to 3.5 cm. broad, those of the 
terminal pair 11.5 to 15 cm. long, 4 to 6 cm. broad. 
Floral spikes single in the axils of the upper leaves, the peduncles ferru- 
ginous-hairy, striate, 1 to 1.5 cm. long, the heads few-flowered; bractlets 
linear-lanceolate, acute, striate, sparsely pubescent, about equaling the calyx 
(9 to 12 mm. long), persistent; flowers sessile; calyx tubular, 10.3 to 12 (11.1) 
mm. long, the tube sparsely covered with a fulvous, appressed pubescence 
mixed with numerous short, purplish hairs, the teeth triangular, acute, 2 to 
3.5 mm. long, densely hairy; corolla tubular, broadening toward the apex, 
silky-villous, 28 to 31 (29.5) mm. long, the lobes triangular, acute, 2 to 3 mm. 
long; staminal tube long-exserted, the filaments purple; ovary 4-sulcate. 
Legume not known. 
Type in the U. 8. National Herbarium, no, 865489, collected at Turrialba, 
Costa Rica, altitude 570 meters, in pastures, flowers, November, 1893, by A. 
Tonduz (Inst. Fis. Geogr. Costa Rica, no. 8391). 
A species conspicuous for the short, almost exalate rachis of the leaves, 
the relatively small leaflets, etc. The calyx has short, very hairy teeth, a 
feature which does not seem to occur in the other species of the group. 
Inga bdiolleyana is dedicated to the memory of the late Prof. Paul Biolley, a 
Swiss naturalist, actively interested during his life in the investigation of the 
flora of Costa Rica. 
Inga jimeneziana Pittier, sp. nov. 
A tree with rounded crown; branchlets angulate, covered with large lenticels, 
the younger parts ferruginous-hairy. 
Rachis of the leaves narrowly winged, sparsely ferruginous-hairy or glab- 
rescent, 5 to 15 cm. long, the petiolar part nude or marginate, 2.5 to 5.5 em, 
long; stipules ovate-lanceolate, subcordate at the base, acute, 1.2 to 2 cm. long, 
0.6 to 0.8 cm. broad, pubescent without, coriaceous, persistent; leaflets 2 or 
8-jugate, rarely 4-jugate, membranous, subsessile (the petiolules not over 1 mm. 
long) ; glands small, mostly long-stipitate ; leaflet blades broadly ovate to ovate- 
elliptic, broadly rounded or subacute at the base, more or less abruptly 
acuminate at the apex, sparsely hairy or glabrescent and lustrous above, with 
the subprominent costa and veins more or less fulvous-hairy, paler and reticulate 
beneath, the costa, veins, and venules more or less fulvous-hairy; leaflets of 
the basal pair 7 to 13.5 cm. long, 3 to 6.5 cm. broad, those of the terminal pair 
14 to 21 em. long, 6.5 to 11 em. broad. 
Floral spikes single or geminate and subpaniculate in the axils of the upper 
leaves, the peduncles 1.5 to 4 cm. long, fulvous-hairy, striate, the flower heads 
elongate; bractlets lanceolate to linear, acute, 1 to 1.5 em. long, pubescent 
without, persistent; flowers sessile; calyx tubular, striate, fulvous-pubescent, 
11 to 13.2 (12) mm. long, the teeth narrow and subulate, 3.5 to 7 mm. long; 
corolla tube narrow, shortly broadened at the apex, white, villous, 31.7 to 82.5 
(32.1) mm, long, the lobes broadly triangular, acute, 2.5 to 3.5 mm. long; 
staminal tube equaling the corolla or shorter, the filaments deep purple, the 
stamens 8 to 8.5 cm. long; style truncate, longer than the stamens. 
Legume sessile, subcuneate at the base, cuspidate at the apex, glabrous, 11.5 
to 30 cm. long, the valves almost flat or slightly depressed, 3 cm. broad, the 
margin concave, bisuleate, 1.5 cm. broad.
