ORCHIDACE^ 



pala lateralia vix 1 mm. longa, subacuta, ovata, usque ad medium 

 connata, membranacea, pellucida. Sepalum dorsale simile. Petala 

 anguste elliptica vel oblonga, obtusa vel subacuta, obscure den- 

 ticulata, .5 mm. longa. Labellum trilobatum, apice bilobulatum, 

 mucrone obtuso interjecto, lobulis angustatis, setaceis, e basi la- 

 belli usque ad lobulum terminalem 1 mm. longum, inter apices 

 loborum lateralium 1 mm. latum ; lobi laterales basilares, trian- 

 gulares vel subquadrati, margine plerumque inaequali. Columna 

 minuta. 



Closely allied to Oberonia neglecta Schltr. from which it dif- 

 fers in the apical lobe of the labellum, in the proportionately 

 shorter lateral lobes and in the slightly larger flowers. In habit 

 O. lineaiifolia is very similar to O. neglecta Schltr. from Borneo 

 and to O. potamophila Schltr. from Sumatra. 



The terminal portion of the labellum resembles very closely 

 the labellum of O. Mannii Hook. f. as illustrated in Icones Plan- 

 tarum t. 2003, f. 2. When one bears in mind the great range of 

 variation that is characteristic of the very delicate lip-lobes in the 

 microscopically small flowers of the alliance to which O. lineaii- 

 folia and O. neglecta belong, it may well be asked if they do not 

 represent the same species. I originally identified my material 

 as conspecific with O. neglecta. Material was submitted to Dr. 

 Schlechter for comparison with his type specimen. On his assur- 

 ance that my material did not agree with O. neglecta and rely- 

 ing on a sketch and analysis of the flower of the type, it was 

 decided to propose a new species. (Plate 114.)
