15 mm. long; staminodium linear-clavate, glandular- 
lepidote, 6-8 mm. long. Style elongate, about 2.8 em. 
long; stigma deeply bifid, the lobes unequal, strongly 
diverging. Ovary subglobose, glabrous. Ovules numer- 
ous, very small. 
SPECIMENS EXAMINED: 
Guatemala: Eastern portion of Vera Paz and Chiquimula, 1885, 
Sereno Watson 474c (Tyre in Herb. Gray); ““Dept. Izabal, between 
Milla 49.5 and ridge 6 miles from Izabal, Montafia del Mico, alt. 65- 
600 m.,’’ April 1, 1940, Julian R. Steyermark 38541 (Coryrrs in Herb. 
Field Mus. No. 1035330; Econ. Herb. Oakes Ames No. 1581). 
Uroskinnera Watsoni, according to field notes accom- 
panying Steyermark 38541, grows in ‘‘grassy places on 
dry slopes’’. It inhabits the same kind of land as Uro- 
skinnera spectabilis with which it is often found. 
Steyermark’s field notes further state of Uroskinnera 
Watson that it isa “‘shrub 2-8 ft. tall. Leaves thickish, 
soft, membranaceous, rich light green above, pale green- 
ish-white beneath. Corolla lilac to deep-orchid, the ven- 
tral half white.’’ 
There is a very striking agreement in size and in diag- 
nostic characters between Watson’s type collection (from 
the eastern part of Vera Paz or Chiquimula) and Stey- 
ermark’s cotype collection (from Izabal). 
On account of its smaller size and its narrower leaves, 
Uroskinnera Watsoniiis vegetatively the most distinctive 
species of the genus. 
Uroshkinnera Watsoni is most closely related to U. 
spectabilis. These two species are similar in having char- 
taceous leaves which are hispidulous above and sericeous 
below, in having a short crowded inflorescence of rose- 
purple flowers, the corollas of which are externally gla- 
brous and internally glandular-lepidote on the lobes; in 
having a 4-dentate, hirsute calyx; in having a glandular- 
lepidote staminodium and in having adeeply bifid stigma.
