Brazil and the territory southward, with the exception of C. noterophilum 
Bur. & Schum., reported from French Guiana. 
WXPLANATION OF PLATHW 106.—Fruit of Clytostoma isthmicum. Natural size. 
Lundia puberula Pittier, sp. nov. 
A vine, the young branchlets puberulous, sparsely covered with elliptic, brown- 
ish lenticels. 
Leaves conjugate; petioles and petiolules terete, puberulous, the former 2 to 
2.5 cm. long, the latter canaliculate, 1.5 to 2 em. long; leaflet blades ovate- 
acuminate at the apex, oblique, rounded-emarginate at the base, 6 to 9 cm. long, 
2.5 to 5 cm. broad, reticulate, glabrous, and almost lustrous above, paler be- 
neath, finely reticulate, the costa and veins puberulous and barbulate in the 
axils. 
Inflorescence paniculate, terminal, many-flowered, the rachis puberulous; 
bracts narrow, acute, pubescent, about 1 mm. long; flowers clustered at the ends 
of the peduncles, these 0.8 to 2.5 cm. long; bractlets linear, pubescent, about 2 
mm. long, caducous; pedicels minutely puberulous, 4 to 5 mm. long; calyx 
tubular, truncate, about 5 mm. long, minutely puberulous without, sometimes 
split laterally; corolla about 3.5 em. long, pinkish purple, pubescent without, - 
glabrous within, the narrow basal tube 1 cm. long, the lobes rounded-obtuse ; 
stamens inserted at the upper end of the basal tube, included, the filaments 9.5 
and 14.5 mm. long, the anther cells divaricate, subfalcate, long-ciliate, 2.3 to 
2.8 mm. long; staminode obsolete; disc none; pistil about 2.8 cm. long, the ovary 
ovoid-oblong, 2 mm. long, minutely white-tomentose, the style smooth, the 
stigma lobes narrow. 
Fruit not known. 
Type in the U. S. National Herbarium, no. 715745, collected at La Palma, 
southern Darién, Panama, flowers, January 26, 1912, by H. Pittier (no. 5499). 
The species is apparently common in old clearings. 
This belongs in the section Eulundia Schum., near Lundia obliqua Sond., 
from which it differs in its conjugate leaflets, glabrous on the upper face, 
eglandular at the base, its many-flowered panicles, its anther cells closely 
ciliate along the line of dehiscence, ete. 
Jacaranda caucana Pittier, sp. nov. 
A middle-sized, deciduous tree, the trunk erect, the crown elongate; young 
branchlets minutely puberulous. 
Leaves unequally twice pinnate, the main rachis 8.5 to 20 cm. long, narrowly 
canaliculate, minutely hairy, the rachis of the pinne 1.5 to 5 em, long, semi- 
terete, broadly canaliculate, minutely hairy; leaflets 7 to 20-jugate, suboppo- 
site or alternate, sessile, ovate-oblong, rounded and very oblique at the base, 
subacute at the apex, sparsely villous above, paler and more densely villous or 
subtomentose beneath, the 4 pairs of veins strongly impressed on the upper face 
of the blade, slightly prominent on the lower face, the margin revolute; ter- 
minal leaflet 7 to 10 mm. long, 8 mm. broad; lateral leaflets 4 to 6 mm. long, 
1.5 to 2 mm. broad. 
Panicles terminal, their main branches about 15 em. long, the rachis and 
pedicels minutely puberulous; branchlets dichotomous; bractlets very small, 
triangular-acute; pedicels 2 to 4 mm. long; calyx broadly cupuliform, about 8 
mm. long, minutely pubescent, distinctly 5-toothed; corolla funnelform-cam- 
panulate, subzygomorphic, about 4 cm. long, blue, glabrous without except for 
sparse white hairs near the apex, hairy within on the veins and glandular-hairy 
at the insertion of the stamens, the tube swollen at the base and then con- 
tracted and curved, the lobes broad and rounded: stamens equally inserted in
