A SYNOPSIS OF THE GENUS 
UROSKINNERA 
BY 
RicHArRD Evans SCHULTES 
For a number of years, the genus Uvroshinnera, a 
member of the Scrophulariaceae, has commanded the 
attention and interest of horticulturists because of its 
beauty and its rarity. 
Lindley described Uroskinnera in 1857, basing the 
genus on the Guatemalan U. spectabilis. For twenty-two 
years thereafter the genus was considered to be mono- 
typic. 
In 1879, however, Hemsley described a second species 
from southern Mexico, naming it Uroskinnera hirtiflora. 
Since that time Uroskinnera has been represented only 
by these two species, neither of which had been collected 
again until very recently. Since herbarium material was 
scanty, and there was but little information concerning 
the habit of the plants, the genus remained imperfectly 
understood. 
Several collections of Uroskinnera were made by the 
author in northeastern Oaxaca in 1939. These are refer- 
able to U.hirtiflora and apparently represent the first 
collections of this plant that have been made in a century, 
and appear to constitute the only material of the species 
in American herbaria. 
In 1989, Mr. Eizi Matuda collected an interesting
