2.5 to 4 mm. long, obtuse or acutish, appressed-pilose outside, soon deciduous; 
leaves opposite, the petioles stout, 5 to 9 mm. long, densely short-pilose, the 
blades mostly oval, sometimes oblong-oval or obovate-oval, 4 to 8.5 cm. long, 
2.5 to 4.5 em. wide, rounded at the base, broadly rounded at the apex, chartace- 
ous, green above, densely short-pilose or pilose-scaberulous, ‘the venation 
prominulous but more or less embedded, paler beneath, densely velutinous- 
pilosulous, the costa and lateral véins prominent, the latter 8 to 10 on each 
side, subarcuate, ascending at an angle of 50° or more, the intermediate veins 
prominulous, laxly reticulate, the margin recurved; cymes subcapitate, 3 to 5- 
flowered, the peduncles very stout, 3 to 10 mm. long, densely short-pilose, the 
flowers sessile, the bractlets subulate, 3 to 4 mm. long, persistent; fruit globose, 
about 8 mm. in diameter, 3 or 4-celled, minutely tomentulose. 
Type in the U. 8. National Herbarium, no. 796186, collected on mountain 
ridges near Gualin, Guatemala, altitude 185 meters, June 15, 1909, by CG. C. 
Deam (no. 6271). 
A very distinct plant, of the group of Guettarda elliptica Swartz. Guettarda 
dichotoma Mart. & Gal., described from Veracruz, may be a near relative, 
but it is an imperfectly known species. 
Guettarda filipes Standl., sp. nov. 
Branches blackish or reddish brown, lenticellate, the branchlets slender, 
densely pilose, the internodes elongate; stipules triangular-lanceolate, filiform- 
acuminate, about 5 mm, long, deciduous; leaves opposite, the petioles slender, 
3 to 8 mm. long, short-pilose, the blades ovate, elliptic, or oblong-elliptic, 3 to 
5.5 em, long, 1.2 to 2.5 em. wide, rounded to acutish at the base, short-acuminate 
at the apex, membranaceous, green above, densely short-pilose, at least when 
young, the venation plane, paler beneath, densely pilose with short, whitish, 
mostly spreading hairs, the costa and lateral veins prominulous, the latter 
about 7 on each side, subarcuate, the intermediate veins mostly obsolete, the 
margin plane; cymes lax, few-flowered, the peduncles subfiliform, 1.3 to 3.5 
cm. long, pilose, the branches short, slender, the flowers partly sessile and 
partly on slender pedicels 1 to 8 mm. long, the bractlets ljpear, equaling or 
much longer than the calyx; calyx appressed-pilose, the limb 1.5 mm. long, 
shallowly bilobate; corolla minutely sericeous outside, the tube slender, 6 to 
7 mm. long, the lobes rounded, 1 to 1.5 mm, long, glabrous within; ovary 
2-celled. 
Type in the U, 8. National Herbarium, no, 302475, collected near Huasemote, 
Durango, Mexico, August 15, 1897, by J. N. Rose (no. 3498). 
Related, although probably not very closely, to G. deamii, described above: 
distinguished by the 2-celled ovary, acuminate leaves, and partly pedicellate 
flowers. 
DESCRIPTIONS OF NEW SPECIES OF SEVERAL FAMILIES, WITH 
MISCELLANEOUS NOTES. 
All the new species described below are Mexican plants. Of 
greatest interest is the Covssapoa, obtained in Oaxaca by Doctor 
Reko, for not only is the species an unusually distinct one but it adds 
another genus to the long list of known Mexican trees. Another 
genus, Tonduzia, also may be reported from Mexico as the result of 
Doctor Reko’s explorations. The two new species of Platanus 
described here are noteworthy additions to one of our smallest genera 
of North American trees,
