STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 115 
the fruit does not have a mucilaginous coat, but he makes the same statement of Lo- 
pimia insignis Fenzl, which is a synonym of L. malacophylla. He could not be certain 
regarding this point from dried fruit alone. 
The only other species of this genus known at present is the type species, Lopimia 
malacophylla. It is characterized by its numerous (18 to 22) involucral bracts, L. 
dasy petala having usually only 12. These are much wider, too, in the latter species. 
There are other prominent differences besides, L. dasypetala having a less abundant 
pubescence and larger flowers. 
Lopimia malacophylia has a wide range in South America, extending from Colombia 
and Bolivia through most of Brazil. It is found also in Cuba and in southern Mexico. 
From the latter region Hemsley ! reports a single specimen collected by Jurgensen 
(no. 909). In the National Herbarium there is a second sheet, collected by E. W. 
Nelson (no. 2479) near Plunia, Oaxaca, altitude 900 to 1,440 meters, March 17, 1895. 
Seeds of this collection were brought to Washington, where the plants were grown in 
the greenhouse, flowering and fruiting in 1897. It may be that the plant in Mexico 
is introduced. 
FOUR NEW SPECIES OF MALACHE FROM PANAMA AND COSTA 
RICA. 
Many of the species of Malache (better known under the name 
Pavonia) are widely dispersed tropical weeds. Others, however, are 
local in their distribution. To the latter group belong four species 
of Panama and Costa Rica which appear to be without names. 
Malache fulva Standley, sp. nov. 
Stems stout, flexuous, densely pubescent with short stout white hairs, besides being 
densely hispid with long yellow hairs; stipules subulate, 5 to 8 mm. long, deciduous, 
hispid; leaf blades elliptic-oblong, esymmetrical, 7 to 14 cm, long, 26 to 55 mm. wide, 
abruptly short-acuminate, rounded at the base, coarsely crenate or crenate-dentate, 
pinnately veined, abundantly hispid on both surfaces, some of the hairs sometimes 
branched; petioles stout, 9 mm. long or less, densely hispid, the uppermost leaves 
nearly sessile; peduncles solitary in the axils or in a terminal few-flowered corymb, 
20 to 75 mm. long, stout, abundantly hispid; involucral bracts about 10, linear-subu- 
late, 15 to 20 mm. long, hispid with yellow bristles; calyx 4 mm. long, puberulent, 
shallowly lobed, the lobes broad and rounded; flowers not seen; fruit hemispheric, 
scarcely lobed; carpels 5, glabrous, with prominent dorsal and lateral nerves and less 
prominent transverse ones, each carpel with 3 slender spinose processes at the apex, 
these spreading, about 1 cm. long, retrorsely barbed at the apex; seeds brown, pube- 
rulent. 
Type in the U. 8. National Herbarium, no. 578479, collected in cultivated fields at 
the Hacienda de Chirripé, Costa Rica, altitude 100 meters, March, 1900, by H. Pittier 
(Inst. Fis. Geogr. Costa Rica, no. 16080). An additional specimen examined is from 
the Hacienda de Zent, Costa Rica ( Tonduz 388). 
A member of the subgenus Typhalaea, but not closely related to any described 
species of the group. The leaves are similar in size and outline to those of M. typha- 
laea and M. rosea, but the inflorescence and fruit are very different. Malache fulva 
may be distinguished at once from all the Mexican and Central American species by 
the abundant yellow, hispid pubescence.
