NEW OR NOTABLE SPECIES OF ARCYTOPHYLLUM. 
The genus Arcytophyllum, a member of the Rubiaceae, is repre- 
sented by some 20 species, confined chiefly to the high mountains of 
northern South America. Several species are contained in the recent 
collections of Mr. Pittier in Colombia and Venezuela, two of which 
are undescribed. The species found in Costa Rica and Panama was 
given a manuscript name several years ago by Dr. Schumann, but 
this has never been formally published. A diagnosis of it is given in 
the present paper. There are included also transfers of 4 species 
previously published under other generic names.

First found by Bonpland on the Silla de Caracas, Venezuela, and collected by Otto 
Kuntze at the same locality in 1874. The species was collected by Mr. H. Pittier 
(no. 6237) in the upper belt of Pico de Naiguaté, State of Miranda, Venezuela, on the 
southern slope at an altitude of 2,400 to 2,765 meters, in May, 1913. Here, too, appar-
