Salvin Biol. Centr.-Am. 5 (1882) t.64) leaves no doubt 
that the collections which I have been able to examine 
are referable to this species. 
Inasmuch as no description of the habit of Uroskinnera 
hirtiflora in the wild state has been published, the follow- 
ing notes may be of interest. Unlike the two Guatemalan 
species, U.hirtiflora is a silvicolous shrub, inhabiting the 
deepest, darkest parts of the rain-forests on steep moun- 
tains. The plant, standing six to eight feet high, is com- 
pletely sheltered by the tall trees so that little direct 
sunlight reaches it. Nevertheless, its leaves are very 
heavily villous-sericeous above and below. It exhibits a 
predilection for well-drained, calcareous terrain which is 
not overgrown with the usual tangle of vines and herb- 
aceous elements. It is usually not present in abundance. 
The flowers of Uroshkinnera hirtiflora are rose-purple 
in all their parts. There is no white on the corolla as re- 
ported for U.spectabilis and U. Watsonn. 
In the original description of Uroshinnera hirtiflora, 
Hemsley did not comment upon the habit of the plant, 
but in an extended description (Biol. Centr.-Am., l.c.), 
he stated that the genus Uroskinnera consisted of ‘‘two 
herbaceous species’’. This is erroneous. The plants from 
which my four collections of U. hirtifora were taken 
were large, rather woody shrubs ranging in height from 
six to eight feet. Furthermore, Hemsley’s figure of U. 
hirtiflora indicates by the thickness of the terminal 
branches and the stoutness of the petioles and size of the 
leaves that the specimens which he studied were portions 
of a shrub. 
Probably because of Hemsley’s statement that the 
plant was herbaceous, Standley did not include Uroshin- 
nera hirtiflora in his Trees and shrubs of Mexico (Con- 
trib. U.S. Nat. Herb. 23 (1920-1926) ). Furthermore, 
in their Flora sinéptica Mexicana (ed. 2 (1910) 161),
