Amesiella Schltr. ex Garay, gen. nov. 
Type: Angraecum philippinense Ames 
Etymology: In honor of Prof. Oakes Ames (1874- 
1950), founder of the Orchid Herbarium of Oakes Ames 
of Harvard University. 
The Philippine orchid flora is well known today be- 
cause of the works of Oakes Ames. According to the 
correspondence preserved in the archives of the Orchid 
Herbarium, Schlechter planned to describe A mesiella, 
based on Angraecum philippinense, but his untimely 
death prevented him from doing so. However, A mesiella 
was published post mortem as a nomen in Notizblatt des 
Botanischen Gartens und Museums zu Berlin-Dahlem 
9; 591, no. 567, 1926. With great satisfaction I correct 
this long-overdue recognition.
