differs in being essentially glabrous. The specimen is very immature, 
the corollas being barely formed. Until mature collections are avail- 
able, it cannot be determined definitely whether Schultes 6937 is only 
a glabrous form of Sanchezia thinophila or a new species. 
The type plant, Schultes states, was growing on a sandy beach at 
the mouth of the Rio Loretoyacu, hence the specific epithet thinophila 
(Gs [@mo-], beach, and $Aéw, loving).

Recently, a number of collections of this curious 
composite have been reported from eastern Colombia 
(Schultes in Bot. Mus. Leafl. Harvard Univ. 18 (1949) 
310, 14 (1949) 47). The two additional collections from 
the Comisaria del Vaupés indicate that Gongylolepis 
maroana is, indeed, one of the most widespread as well 
as dominant shrubs on the isolated quartzite areas in 
Amazonian Colombia. 
Cotomspia: Comisaria del Vaupés, Macaya River, Mount Chiribi- 
quete. ““Bush’’. July 24, 1943, Richard Evans Schultes 5742.—Comis-
