Type in the U. 8. National Herbarium, no. 1,135,663, collected in the 
wooded ravine of the Rio Ataco, among mountains back of Ahuachapdan, 
Department of Ahuachapdn, Salvador, altitude 800 to 1000 meters, January 
10, 1922, by Paul C. Standley (no. 19783). 
‘ADDITIONAL SPECIMENS EXAMINED: Satvapor: Along stream, vicinity of 
Ahuachapan, January 14, 1922, Standley 19964. In forest, Sierra de Apaneca, 
region of Finca Colima, Department of Ahuachapdn, January 17 to 19, 1922,

This shrub bears the vernacular names “‘canilla,” ‘“‘tatascamillo,” and 
“vara de zope.”’ Unfortunately all three collections are too mature to show 
the character of the flowers well. A single imperfect ray adhering to one of 
the heads was yellow, nearly linear, and appeared to be scarcely longer than 
the style branches. All the flowers are probably yellow. The species is 
very similar in general appearance to Perymeniwm strigillosum (Robins. & 
Greenm.) Greenm.

ciliate; leaf blades of the stem leaves ovate or oblong-ovate, 2.5to7 cm. long, 1.2
