Hitherto, this beautiful epiphytic shrub has been 
known apparently from only three collections, all of 
which were cited in the original description. According 
to the citations, these collections were made in 1842 by 
Liebmann in the Chinantla of northeastern Oaxaca very 
close to the locality of Schultes & Reko 724.

Apparently, this rare shrub has not hitherto been col- 
lected in the State of Oaxaca. The type collection was 
made in Vera Cruz. 
Ruellia stemonacanthoides (Oerst.) Hemsley in 
Godman & Salvin Biol. Centr.-Am. Bot. 2 (1882) 507. 
Mexico: District of Choapam, near Rio Chiquito, long. 96°02’, 
lat. 17°38’, alt. about 150 m., May 2, 1939, Schultes & Reko 739; Ta- 
basco, June 19-25, 1939, Matuda 3472. 
Schultes & Reko 739 and Matuda 3472 are apparently 
the first Mexican collections of Ruellia stemonacanthoides 
from outside of the Yucatan Peninsula. According to 
Leonard (in Bot. Maya Area: Misc. Pap. 10 (1986) 206), 
this species is known from Campeche, British Honduras, 
Guatemala, and Costa Rica. It is very infrequent in 
northeastern Oaxaca.
