Column short, with a warty, elliptical staminode on each 

 side; anther-tubes horizontal not quite as long as caudioles 

 but at least as the narrow rostellum lying between them; 

 stigmatic processes fleshy, oblong-lanceolate, extending for- 

 ward on either side of the orifice to the spur; pollinia com- 

 posed of numerous packets of sectile pollen; caudicles 

 extremely long + 2'5-3 mm., transparent, passing downwards 

 and forwards, guarded below by the anther-tubes beyond 

 which their tips project; glands approximate and quite 

 exposed. 



This species falls under Kranzlin's Section "Medusae- 

 formes" and approaches H. ternatea, Reich, f., the habitat of 

 which is given as the Sunda Islands ; in the Island of Ternate. 



Cryptostylis erythroglossa, Hayata. 



Root a creeping rhizome. Plant glabrous, stem slender. 

 Leaves 2 (one broken off in specimen), petiolate, elliptic- ovate, 

 acuminate, 11 cm. long by 4 cm. in its widest part (without 

 the petiole) ; petiole slender, + 5 cm. Bracts clasping, narrow 

 acuminate; 15-30 mm. long. 



Flowers inverted, green white and red, rather large, + 

 40 m.m. diameter. Lateral sepals green, spreading linear, 

 acute, +15 mm. ; dorsal sepal green, linear, spreading, same 

 width as lateral sepals, length not determined (owing to 

 damage to specimen). Lateral petals green, spreading, filiform, 

 much shorter and narrower than sepals, + 8 mm. Labellum 

 ovate-lanceolate, +15 mm. long and + 5 mm. broad in 

 widest part, white with reddish base, spotted, multi-nerved, 

 margins entire, acute ; base sessile, obtuse, clasping the anther,
