Hapalochilus xanthophaeus (Schltr.) Garay & Kittr., comb. 



nov. 



Basionym: Bulbophyllum xanthophaeum Schltr. in Fedde, 

 Rep. Beih. 1:729, 1913. 



Hymenorchis serrulata (Halle) Garay, comb. nov. 



Basionym: Saccolabium serrulatum Halle in Bull. Mus. Nat. 

 Hist. Nat. Paris ser. 3, Sect. B, Adans. 4: 410, 1981. 



The excellent illustrations by Dr. Halle leaves no doubt that 

 it is a new member of the genus Hymenorchis Schltr. The serrate 

 leaves, the structure of the pollinia and the delicate white flowers 

 among others are the characters upon which Schlechter based his 

 genus. The species are basically native to New Guinea with the 

 exception of H. javanica (T. & B.) Schltr. and H. Vanover-

Pleurothallis jalapensis (Krzl.) Garay, comb. nov. 



Basionym: Masdevallia jalapensis Krzl. in Fedde, Rep. Beih. 

 34: 117, 1925. 



It is a mystery why Kraenzlin called this species a Masdeval- 

 lia. It belongs to a small group of closely related species, but 

 readily identifiable by the long acuminate, appressed bracts. The 

 following species comprise this natural group: P. Liebmanniana 

 Krzl., P. cobanensis Schltr., P. multirostris Rchb.f. and P. 

 racemiflora (Sw.) Lindl. 



Sarcoglyphys potamophila (Schltr.) Garay & Kittr., comb. nov. 

 Basionym: Sarcanthus potamophilus Schltr. in Fedde, Rep. 3: 

 279, 1907. 



Syn.: Cleisostoma potamophilum (Schltr.) Garay in Bot. 

 Mus. Leafl. 23: 173, 1972. 



At the time when the genus Sarcoglyphys was established, the 

 highly elevated anther bed has been overlooked in Schlechter's 

 drawing. The genus is new to Borneo.
