PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 471 
The present species belongs to the group of Machaerium seemanni, on account 
of its sessile flowers and other characters, but it differs in its pubescence, the 
number, shape, and size of its leaflets, and its rather long-stipitate and broader 
pods. 
4, Machaerium seemanni Benth. in Seem. Bot. Voy. Herald 110. 1853. 
Machaerium campylocarpum Donn, Smith, Bot. Gaz. 44: 109. 1907. 
An unarmed spreading shrub; branchlets terete, striate, at first ferruginous- 
pubescent. 
Leaves 7 to 11-foliolate, the rachis slender, 5.5 to 9 cm. long, terete, sparsely 
ferruginous-hairy; leaflets coriaceous, the petiolules about 2 mm. long, ferru- 
ginous-hairy, the blades ovate or ovate-lanceolate, rounded or subemarginate at 
the base, short-obtuse or acute-acuminate at the apex, 1.5 to 5 em. long, 0.7 to 
2 em. broad, glabrous, lustrous and dark green above, paler beneath, more or 
less villous or pilosulous, especially along the costa, and finely reticulate; 
stipules caducous, wanting. 
Inflorescences axillary or terminal, racemose, the rachis (or peduncle) not 
over 2 em. long, ferruginous-pubescent ; bracts and bractlets persistent, shorter 
than broad, truncate, conchoid, minutely pubescent; flowers sessile, about 7 
mm. long; bractlets suborbicular (broader than long), ferruginous-pubescent, 
1 to 1.5 mm. long; calyx persistent, campanulate, 8 to 3.5 mm: long, densely 
ferruginous-hairy, the teeth inconspicuous; petals persistent, purple ; standard 
orbicular, ferruginous-sericeous, the claw very short, the blade orbicular, sub- 
emarginate at the base, bilobulate at the apex, about 5.5 mm. long and 7 mm. 
broad; wings elongate, the claw 1.5 to 2 mm. long, the blade auriculate, obo- 
vate, densely villous-barbate without, 5.5 mm. long, 2.3 mm. broad; carinal 
petals faleate, the claw as in the wings, the blade broad, straight on the vexillar 
margin, densely villous-barbate on the carinal half without, about 5 mm. long 
and 3 mm. broad; stamens monadelphous, the filaments villous; ovary pubes- 
cent, 1-ovulate. 
Legume 5 to 6 cm. long, short-stipitate (the stipe 4 to 5 mm. long), at first 
minutely pubescent, the seminal part arcuate, 2 em. long and 7 to 9 mm. broad, 
the wing obtuse or subacute, 1.5 to 1.7 cm. broad, the vexillar margin thin 
and arcuate, the carinal margin almost straight and thick. 
Type from El Boquete de Chiriqui, Panama (Seemann 1681). 
SPECIMENS EXAMINED: 
Covems1a: Foothills of Santa Marta, altitude about 700 meters, flowers, 
June, 1900, Herbert H. Smith 2088. 
Panama: Arid hills near Las Cruces de Churué, between Aguadulce and 
Ol4, Province of Coclé, fruits, December 9, 1911, Pittier 5094. Cerro 
Vaca, eastern Chiriquf, altitude 900 meters, fruits, December 26, 1911, 
Pittier 5310. 
Costa Rica: Hacienda Jiménez, Pefias Blancas, Diquis Valley, altitude 
600 meters, flowers and fruits, February 7, 1898, Pittter (Inst. Fis. 
Geogr. Costa Rica, no. 12163). 
The first diagnosis of this species, described from Chiriquf, does not mention 
the fruit. In his Synopsis of Dalbergiae, published seven years later, Bentham 
completed his first description with that of a pod of a Venezuelan specimen, 
Fendler 1685, representing a very closely related but certainly distinct 
species. This resulted in Capt. John Donnell Smith’s redescribing the shrub 
as a new species. My specimens from Panama agree perfectly with the 
original diagnosis and I have been able to convince myself by direct comparison 
that they are absolutely identical with the type of Machaerium campylocarpum 
Donn. Smith.
