NOVELTIES IN THE ORCHID FLORA 
OF THE GUAYANA HIGHLANDS II* 
BY 
CHARLES SCHWEINFURTH 
THE following paper is the last and concluding article 
treating the new species and other novelties which have 
recently appeared during my work on the Guayana 
Highlands. These novelties consist of seven new species 
(including a genus now first recorded for the New 
World), one new variety, two new combinations, two 
new names and one new form. There are included also 
the description and citation of two orchids which are 
highly variable and have not previously been reported 
from the area under investigation. Of both species, the 
accompanying detailed drawings are the first careful il- 
lustrations that have appeared. 
As in the former paper (Bot. Mus. Leafl. Harvard 
Univ. 19, no. 9 (1961) 195-214), the order of genera 
follows the system proposed by Dr. Rudolph Schlechter 
in Notizblatt der Botanischen Gartens und Museums, 
Berlin-Dahlem 9, no. 88 (1926) 563-591. 
Spiranthes callifera C. Schweinfurth sp. nov. 
Herba terrestris, mediocris, circiter 38 cm. alta. Radices 
numerosae, fasciculatae. Folia septem ut videtur, plan- 
* All of these investigations were made possible by a grant from 
the National Science Foundation.
