Uroskinnera spectabilis was described from two collec- 
tions from Guatemala (Skinner s.n. and Wendland s.n.), 
the exact localities of which were not given. These col- 
lections are preserved in the Herbarium at Kew. Accord- 
ing to Hemsley (in Godman & Salvin, Biol. Centr.-Am., 
Bot. 2 (1881-82) 447), who presumably examined the 
Skinner and Wendland material when he drew up the 
description of Uroskinnera hirtiflora, U. spectabilis is 
**not uncommon near Quirigua in the valley of the Mon- 
tagua, Guatemala.’’ This locality is in the east-central 
part of Guatemala where Steyermark rediscovered and 
collected the plant in 1940; Steyermark’s collection was 
made in the Departamento de Izabal. Apparently Uro- 
skinnera spectabilis is a localized endemic of this part of 
Guatemala. 
According to the field notes which accompany Steyer- 
mark 38571, Uroskinnera spectabilis inhabits ‘‘dry, pine 
slopes’? and is a “‘shrub 5 feet tall.’’ These notes indi- 
cate a different habitat than that of Uroskinnera hirtiflora 
which exhibits a predilection for the damp, shady rain- 
forests of Oaxaca. Uroskinnera Watsonii grows together 
with U. spectabilis in dry situations; thus, there appears 
to be a fundamental ecological difference between the
