PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 79 
34. Lonchocarpus guatemalensis Benth. Journ. Proc. Linn. Soc. Bot. 4: Suppl. 
87. 1860. FIGuReE 29. 
A deciduous tree, the branchlets grayish, glabrous, covered with numerous subor- 
bicular lenticels. 
Leaves 5 or 7-foliolate, at maturity entirely glabrous, the rachis terete (not canalicu- 
late), 4.5 to 9.5 cm. long. Leaflets coriaceous, sparsely pellucid-punctate, the petio- 
lules canaliculate, 4 to 6.5 mm. long, the blades ovate-oblong (the terminal one often 
obovate), subcuneate at the base, shortly obtuse-acuminate at the apex, 4 to 10 cm. 
long, 2 to 5.2 cm. broad, dark green and sublustrous above, paler beneath, the costa 
prominent. Stipules not seen. 
Racemes axillary on foliate or defoliate nodes, solitary, geminate, 3 to 5-fasciculate, 
or forming small branched panicles, the rachis more or less grayish-pubescent, 6 to 14 
cm. long. Flowers preceding the new leaves or appear- 
ing at about the same time. Peduncles and pedicels 
grayish-pubescent, the former very short (2 mm. long or 
less), the latter about 4 mm. long; bracts and bractlets 
ovate-acute, very small, grayish-pubescent without, gla- 
brous within, the latter slightly remote from the calyx. 
Calyx cupulate, subturbinate at the base, 4.5 to 5 mm. 
long, densely grayish-pubescent, the margin (distinctly 
5-toothed in the bud) sinuate, slightly 5-lobulate. 
Petals pinkish or purplish, densely yellow-dotted, the 
carinal ones cohering; standard orbicular, more or less 
oblique, elobate but callous-plicate at the base, emargi- 
nate at the apex, the claw 3.5 mm. long, the blade 9.5 
mm. long, 11 mm. broad, densely silky-pubescent with-

late on the vexillar side, pubescent along the carinal , 
side without, the claw nearly 5 mm. long, the blade 7 to 7.5 mm. long, 3.7 mm. 
broad. Vexillar stamen free at the base, the margins of the openings in the 
staminal tube callous-thickened. Ovary sessile, linear, densely grayish-hairy, about 
7 mm. long, 7-ovulate; style arcuate, hairy at the base; stigma subcapitellate. 
Fruit not known. 
Type (in flower) collected in Guatemala by Friedrichsthal. 
The above description is from J. D. Smith’s no. 7852, collected at Cubilquitz, Alta 
Verapaz, Guatemala, at an altitude of 350 meters by H. von Tiirckheim, in April, 
1901. Bentham cites also Jurgensen 159 from southern Mexico. To this species I 
refer further Kerber 420, from Mexico; Tonduz (Inst. Fis. Geogr. Costa. Rica, no. 
13860), collected at Nicoya, Costa Rica; and sheet no. 48928 of the U. 8. National 
Herbarium, collected by C. Wright in Nicaragua. 
Bentham places this species at the head of his section Neuroscaphi and describes 
the vexillar suture as concave and 3.2 mm. broad. On the other hand, the tree just 
described, most of whose characters agree with those ascribed to L. guatemalensis, has 
the pellucid-punctate leaves of the species of the section Punctati and the yellow- 
spotted petals of some of them. It would so be intermediate between the true Loncho- 
carpi and the group forming the genus Neuroscapha Tulasne. I do not know, how- 
ever, whether the immature legume described by Bentham really belongs to the type 
specimen, and in the negative case, either a confusion or a misplacing of species has 
been made. The fruits are indispensable to elucidate the point. 
Lonchocarpus guatemalensis differs from the species of the section Punctati in 
the absence of basal lobules on the standard and in the more developed auricles
