rachis, including petiolar part, 1 to 4 cm. long, narrowly winged and auricu- 

 late at least under the terminal leaflet ; leaflet blades ovate or ovate-elliptic, 

 rounded or cuneate at the base, obtusely short-acuminate, subcoriaceous, 

 lustrous, the terminal leaflet o to 10 cm. long, the primary veins numerous, 

 parallel, and conspicuous. 



Racemes axillary or terminal, the short slender glabrous peduncles with 

 2 to 4 flowers; pedicels filiform, 1 to 1..5 cm. long; bracts small, setaceous; 

 bracteoles very small or none; buds quite glabrous, subglobose, hardly 4 mm. 

 in diameter; petal orbicular, unguiculate, a little longer than the calyx; 

 stamens IS to 20, almost all equal, twice longer than the calyx, the anthers 

 ovate; ovary stipitate, narrow, glabrous, 5- or 6-ovulate, attenuate to a short 

 style, the stipe a little shorter than the calyx. 



Legume short-stipitate, obliquely ovoid, long-acuminate, 4 to 5 cm. long, 

 thick and carnose; seed oblique-ovoid, the aril lacerate, the raphe very 

 prominent. 

 Type IvOCALITy: Near the source of the Galibi River, French Guiana. 



This species was collected on Tobago Island by Seemann (no. 1687), but I 

 have seen no specimens of it. 



4. Swartzia trifolia Pittier, sp. nov. 



Small tree, 4 to 5 meters high, the trunk 8 to 12 cm. in diameter, the 

 branchlets, leaves, and inflorescences entirely glabrous, the bark dark red 

 and smooth. 



Leaves usually 3-foliolate, seldom 5-foliolate, coriaceous; stipules setaceous, 

 stiff, about 4 mm. long; rachis 2 to 5 cm. long, terete, winged-auriculate, the 

 wings broader at the auricles; leaflets subsessile, the blades lanceolate, more 

 or less oblique and rounded at the base, obtusely short-acuminate at the apex, 

 the lateral ones 4. .5 to 7 cm. long, 2 to 2. .3 cm. broad, the terminal one 5.5 to 

 9 cm. long, 2 to .3.5 cm. broad, the primary veins about 16, anastomosing 

 along the margin, the venation conspicuous on both sides. 



Flowers not known. 



Fruiting pedicel about 1 cm. long; stipe 8 mm. long; fruit glabrous, 1-seeded, 

 ovoid, acuminate, 3.5 cm. long, 1.5 cm. broad between the sutures; seed 

 ovoid-subreniform, 2.5 cm. long, brown and lustrous. 



Type in the U. S. National Herbarium, no. 677726, collected on the savanna 

 of La Tortuga, between El Boquete and Caldera, Panama, at an altitude of 

 about 400 meters, in fruit, March 21, 1911, by H. Pittier (no. 3343). 



This species is so well characterized by its peculiarly shaped leaves and 

 narrow leaflets that even in the absence of the flowers I do not hesitate to 

 describe it as new. 



5. Swartzia myrtifolia J. E. Sm. in Rees' Cycl. 34: Swartzia no. 5. 1819. 



Small tree, the slender branchlets as well as the leaves and inflorescences 

 glabrous or slightly pubescent. 



Leaves 3-foliolate or sometimes 1-foliolate; stipules subulate, 3 to 4 mm. 

 long; rachis slender, marginate and more or less distinctly auriculate below 

 the insertion of the leaflets, 2.5 to 5 cm. long; leaflets subsessile, the blades 

 ovate or ovate-oblong, rounded or cuneate at the base, obtusely short-acum- 

 inate at the apex, subcoriaceous, nitidulous, the primary veins numerous and 

 prominent on both sides; lateral leaflets 6.5 to 8 cm. long, 3 to 4 cm. broad; 

 terminal leaflet 6.5 to 14.5 cm. long, 5 to 7 cm. broad.
