" Foliis membranaceis lato-linearibus inaequali-obtusis, spicis 

 elongatis flexuosis densifloris, labelli limbo ovato concavo." — 

 Blume, I. c. 



The specimens which I refer to P. densi flora are robust, with 

 oblong leaves about 2 dm. long by 2.5-3 cm. wide. Peduncle 

 exceeding 3 dm. long, and with the raceme longer than the leaves. 

 Flowers numerous in slender, strict racemes. Bracts conspicuous, 

 linear, about 5 mm. long, exceeding the flowers. Labellam about 

 1 mm. long, 1.5 mm. wide, shortly clawed. In well-developed 

 specimens the persistent bases of the distichous equitant leaves 

 form a semicircle. 



For an explanation of nomenclatorial discrepancies, reference 

 should be made to the note accompanying P. Myosurus below.
