on one side than on the other, nerves ad reticulations obsolete. 
Panicles terminal, about 20 cm long, the branches rather few, 
densely brownish-pubescent with short hairs, densely many- 
flowered. Flowers not seen. Pedicels in fruit pubescent, 3 to 
4 mm long; persistent calyx sparingly rusty-pubescent, inequi- 
lateral, 3 to 4 mm in diameter. Pods glabrous, about 5 cm long, 
1.4 cm wide, the basal seed-bearing portion somewhat turgid, 
nearly black when dry, very obscurely reticulate, subrhomboid- 
ovate in outline, about 1.5 cm long and 1.2 cm wide, the wing 
brown, shining, the upper side slightly curved, the style subper- 
sistent as a long slender apiculus up to 1.5 cm long, falling 
and leaving a very short apiculus, the wing broadly rounded at the 
apex, slightly narrowed above.

(original number 12) October 29, 1914. 
A species manifestly allied to Pterolobium densiflontm Prain of the 
Malay Peninsula and P. microphyllum Miq. of Java. From the former it 
is distinguished by its shorter pinnae; rather fewer leaflets, which are 
smaller in size; its shorter inflorescence; and its rather wider wing, which 
is distinctly curved along the upper margin and not narrowly rounded at the 
apex. From Miquel’s species it is distinguished by its fewer pinnae and 
leaflets, larger leaflets, and pubescent pedicels. 
SPATHOLOBUS Hasskarl 
SPATHOLOBUS OBLONG I FOLI US sp. nov. 
Frutex scandens partibus junioribus inflorescentiisque exceptis 
glaber ; foliolis oblongis, usque ad 22 cm longis, acuminatis, basi 
acutis, nervis utrinque 9, prominentibus, adscendentibus, rhachi- 
bus haud productis ; paniculis axillaribus, dense tomentosis, sup- 
pyramidatis, pedunculatis, circiter 20 cm longis, floribus circiter 
8 mm longis, in ramulis ultimis racemose dispositis; fructibus 
junioribus dense adpresse tomentosis. 
Scandent, glabrous or nearly so except the younger parts and 
the densely tomentose inflorescences. Branches terete, lenticel- 
late. Petioles glabrous, 5.5 to 7 cm long, not produced beyond 
the lateral leaflets, the stipels linear, about 3 mm long; leaflets 
oblong, subequally narrowed to the acute base and the rather 
prominently acuminate apex, pale or brownish and shining when 
dry, 18 to 20 cm long, 5 to 6.5 cm wide, coriaceous, the terminal 
one equilateral, the others more or less inequilateral, their petio- 
lules black when dry, 8 to 10 mm long ; lateral nerves 9 on each 
side of the midrib, prominent, ascending. Panicles axillary, 
about 20 cm long, peduncled, subpyramidal, the rachis and 
branches rather densely tomentose with spreading ferruginous 
hairs, these in age becoming rather pale. Flowers racemosely
