A NEW SPECIES OF BAUHINIA FROM PANAMA. 
Bauhinia ligulata Pittier, sp. nov. 
Section Pauletia. A large, unarmed tree, up to 40 meters high and 80 cm, in 
trunk diameter. Bark brownish, rimose. Trunk straight, the limbs short, 
forming an elongate crown. Wood very hard. 
Leaves petiolate, the petioles 2 cm. long, slender, deeply sulcate; blades 
coriaceous, 4 to 10 cm. long, 4 to 7.5 cm. broad, ovate, slightly emarginate at 
the base, bicuspidate at the apex with two short, subacute tips (sinus seldom 
over 12 mm. deep), smooth and almost shining above, grayish and minutely 
pubescent beneath; veins 13, the basal pair marginal, very salient beneath. 
Stipules ovate-elliptic, very small, scarious, caducous. 
Inflorescences terminal, or of axillary, multiflorous, spiciform racemes at the 
ends of the branchlets. Buds claviform, ferruginous-pubescent, 2 to 2.5 cm. long 
just before anthesis. Flowers pedicellate, medium-sized, the bracts very small, 
caducous, the pedicels 2 to 6 mm. long, ferruginous-pubescent. Receptacle 
obconical, short-stipitate, about 7 mm. long. Calyx lobes 5, narrow, about 14 
mm. long, more or less adnate, curled and reflexed in the later stages of anthesis. 
Petals 5, ovate-elliptic, attenuate at the base and short-unguiculate, acute at 
the tip, 3 cm. long, 6 mm. broad, slightly curled and sinuate on the margin, of a 
beautiful lilac color with the rib and pinnate veins dark purple. Stamens 10, 
all fertile, 5 long and 5 short, free to the base, entirely glabrous; filaments of 
long stamens about 25 mm. long, incurved, thicker at base; anthers ovate- 
elliptic, more or less open at the base, about 5 mm. long. Pistil glabrous, adnate 
at the base to the tube of the receptacle, then surrounded by two spathaceous 
ligules, these inserted on the receptacle inside the stamens, acute at the apex, 
hairy on the margin, 6 to 7 mm. long; ovary stipitate, 5 or 6-ovulate; style 
thick, the stigma papillose, depressed in the center, somewhat 8 or 5-lobed. 
Fruit not known. 
Type in the U. S. National Herbarium, no. 679475, collected in the forests 
around Puerto Obaldfa, San Blas Coast, Panama, near sea level, in flower, 
September 2, 1911, by H. Pittier (no. 4834). 
This remarkable species is probably the largest representative of the genus. 
The individual felled to obtain specimens measured 31 meters from foot to top 
and 68 em. in trunk diameter, and a few of the other trees around this were 
much larger. It belongs to the group Pauletia with ovate or broadly elliptic 
petals, but differs from all the other species of the section by its short bicus- 
pidate leaves and the form and size of the petals, and by the spathaceous envel- 
opes at the base of the pistil, a character apparently not noticed heretofore in 
any other species of the genus. 
FABACEAE. 
A NEW SPECIES OF ATELEIA FROM COLOMBIA. 
Ateleia herbert-smithii Pittier, sp. nov. Figure 51. 
A tree, the young branchlets rather thick, knotty, lenticellate, at first minutely 
fulvous-pubescent, later glabrate. 
Leaves 7 or 9-foliate, the rachis slender, terete, attenuate from the base, 
glabrous, 10 to 18 cm. long; stipules wanting or early caducous. Leaflets 
alternate, membranous; petiolules minutely pubescent, 4 to 8 mm. long; blades 
ovate, inequilateral, broad, subcordate, truncate, or abruptly acutate at the 
base, attenuate-acuminate and rounded-obtuse at the apex, 4 to 9.5 cm. long,
