GRIFFITHIANTHUS nomen novum 
Griffithia Maingay non Wight & Arnott. 
The generic name Griffithia of Maingay was not published 
until 1893, and then by King’ from Griffith’s manuscript, al- 
though characterized by Maingay many years earlier. The type 
of the genus is Polyalthia magnoliaeflora Maingay ex Hook. f. 
& Th.,’? published with the comment: “referred to a new ge- 
nus in Maingay’s MSS.” The specific name was altered from 
Maingay’s magnoliaepetala to magnoliaeflora. 
The generic designation Griffithia was used in 1834 by Wight 
and Arnott for a group of rubiaceous plants, and about 14 specific 
names have been published under Griffithia of Wight & Arnott 
by various authors. Although Griffithia W. & A. is now consid- 
ered to be a synonym of Randia, I maintain that the earlier 
use of the name by Wight & Arnott invalidates Griffithia of 
Maingay, and accordingly here propose a slight modification 
of Maingay’s generic name. 
The genus has three species in the Malay Peninsula and at 
least one in the Philippines.
