PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 119 
Machaerium madeirense Pittier, sp. nov. 
A tree, the branchlets terete, at first densely ferruginous-pubescent. 
Leaves 5 or 7-foliolate, the rachis puberulous, angular or terete, 4.5 to 8 cm. 
long. Leaflets coriaceous, the petiolules brownish-pubescent, thick, 4 to 6 mm. 
long, the blades ovate, broadly rounded or rounded-cuneate at the base, obtusely 
acuminate, 2 to 10 cm. long, 1.5 to 4.5 em. broad, glabrous above, paler and 
minutely puberulous beneath. Stipules caducous, not seen. 
Inflorescences terminal, paniculate, 15 to 20 em. long, the rachis ferruginous- 
pubescent, the branchlets of the first order of peduncles 1.5 to 3 cm, long, 5 to 
10-flowered. Bracts and bractlets caducous. Flowers short-pedicellate, the 
other details not known. 
Legume 5.5 to 8 cm. long, short-stipitate (the stipe about 3 mm. long), sparsely 
ferruginous-pubescent all over, the seminal part small, 1 to 1.5 cm, long, 0.5 cm. 
broad, ovate, straight, the wing membranous, cultrate, obtuse, prominulous- 
reticulate, 11 to 12 mm, broad. 
Type in the John Donnell Smith Herbarium, collected at the falls of the 
Madeira River, Brazil, in fruit, October, 1886, by H. H. Rusby (no. 1323). 
Related perhaps to Machaerium acuminatui, but obviously distinguished from 
it by the pedicellate flowers and small pods. 
Machaerium milleflorum Pittier, sp. nov. FiGcure 56. 
A shrub or small tree, scarcely armed, the young branchlets terete, fer- 
ruginous-tomentose. 
Leaves 21 to 27-foliolate, the rachis slender, 9 to 12 cm, long, ferruginous-to- 
mentose. Leaflets membranous, the petiolules ferruginous-hairy, 1 mm, long or 
less, the blades ovate-oblong, the terminal one obovate, 
oblique, rounded at the base, rounded, often emarginate, 
sometimes acute and mucronulate at the apex, 1 to 3 
em. long, 0.6 to 1.2 cm. broad, dark green and sparsely 
pilosulous above, sparsely villous or pilosulous beneath, 
the costa and margin more densely ferruginous-hairy ; 
veins somewhat distant, irregular, profusely anasto- 
mosed, the principal ones running into the marginal 
nerve. Stipules rather small, indurate-spinescent, acute-

like), 10 to 12 cm. long; peduncles cymoid, fasciculate at 
the nodes, slender, many-flowered, 1 to 3 cm. long. Bracts indurate-spinescent,

about 1 mm. long, 1 to 1.5 mm. broad. Calyx campanulate, 3 to 3.5 mm. long, 
striate, purple, glabrous or minutely pilosulous, the teeth obtuse, about equal in 
length, but the vexillar ones broad. Petals pink (?) ; standard densely fulvous- 
hairy without, not reflexed, the claw obliquely inserted, about 1 mm. long, the 
blade orbicular, rounded or subtruncate at the base, deeply emarginate at the 
apex, the lobes rounded, about 5.5 mm. long, 6.5 mm, broad; wings broadly ob-
