PITTIER—-PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 239 
reflexed at the apex, about 3.5 mm. long, the anthers cordate; disc annular, 
pulvinate, densely hairy; ovary ovoid-oblong, about 2.5 mm. long, substipitate, 
smooth, minutely ferruginous-pubescent; style thick, shorter than the stamens, 
hairy except at the apex. 
Type in the U. S. National Herbarium, no. 715696, collected near Remedios, 
eastern Chiriqui, Panama, among remnants of forest, flowers, December 30, 
1911, by H. Pittier (no. 5467). 
This species is supposed to belong to the section Dipterae and does not seem 
ever to have been described. It may correspond to the Guatemalan tree called 
Terminalia excelsa by Liebmann, but not further characterized. This latter 
name, however, could not stand for this species, since it has been used subse- 
quently by Glaziou to designate a Brazilian tree. 
Terminalia hayesii Pittier, sp. nov. 
A tree (?), the ultimate branchlets ferruginous-pubescent. Leaves mem- 
branous, clustered at the ends of the branchlets, eglandular, the petioles shal- 
low-canaliculate above, ferruginous-pubescent, thicker at the base, 5 to T mm, 
long, the blades obovate-oblong, long-cuneate at the base, abruptly short-acu- 
minate at the apex, 6.5 to 11 cm. long, 2.3 to 3.7 cm. broad, dark green and 
sparsely pubescent above, paler, reticulate, and ferruginous-pubescent on the 
costa beneath, ciliate on the margin at the base. Floral spikes densely flowered, 
growing from the base of the new shoots, the rachis 6 to 12 cm. long, villous- 
tomentose; flowers sessile; calyx sessile on the ovary, cupuliform, 5-lobulate, 
grayish-villous without and within, the limb about 1.5 mm. high, the lobes 
triangular, subacute, reflexed, 0.7 to 0.8 mm, long; stamens 10, glabrous, about 
3 mm. long, the anthers ovate; disc inconspicuous, densely villous-tomentose ; 
ovary ovoid, sessile, 1 mm. long, densely long villous tomentose; style shorter 
than the stamens, villous except at the apex. 
Type in the U. S. National Herbarium, no. 202835, collected in Panama by 
Sutton Hayes in 1859-60. 
The American species of the genus Terminalia have been so imperfectly 
described that it is often difficult to distinguish them. The one just described 
may be either the 7. obovata or T. buceras indicated in Biologia Centrali- 
Americana as collected by Hayes, but in neither case would the specimens 
justify the identification. These latter are characterized mainly by the short, 
densely villous ovary and by the relatively broad limb of the equally villous, 
cupuliform calyx, with reflexed lobes. 
THE MEXICAN AND CENTRAL AMERICAN SPECIES OF COMBRETUM, 
SECTION MICROPETALAE. 
The section Micropetalae Engl. & Diels, of the genus Combretum, 
includes about 17 South and Middle American species, characterized 
within the genus by their large flowers, brilliantly colored in several 
hues of red and yellow. The best known South American species is 
probably (. loeflingti Eichl., extending from southern Brazil to 
Colombia. The Central American -collections have been referred 
generally to C. farinosum H. B. K., but an examination of the speci- 
mens under that name in the United States National Herbarium 
shows this species to be exclusively Mexican, the Central American 
forms representing 3 old species, another described by Capt. John 
Donnell Smith as a variety of C. farinosum, and 4 new types.
