Sepals nearly equal ; the posterior erect, concave ; 

 the lateral ones spreading, free. Petals narrow, cohering 

 with the dorsal sepal into a galea. Labellum very shortly 

 adnate to the base of the column, erect, cymbiform or 

 saccate in its lower half, two calli or spurs within the sac 

 near the base, contracted beyond the sac, and then 

 dilated into a shortly- clawed or sessile entire two- winged 

 terminal lobe. Column very short, two-wdnged or keeled 

 in front ; stigmatic lobes two, lateral. Anther erect or 

 inclined forward with contiguous cells ; polhnia two, 

 pyriform, attached by an oblong or elliptical gland to the 

 erect rostellum with often an intermediate apiDendage or 

 linear caudicle. Pollen coarsely granular (sectile). Capsule 

 small erect, ovoid or nearly globular. 



Slender terrestrial herbs, with a creej)ing rhizome. 

 Leaves with petioles expanding at their bases into loose 

 membranous sheaths. Flowers small, sessile on a dense 

 or lax spike. 



Distribution. — Species approximately 60, mostly 

 Indian or Malayan with a few tropical African species 

 and one endemic in S. Africa. Several species have also 

 been recorded from the PhiHppines ( Adenostylis) and 

 Formosa, likewise from New Guinea, Bismarck Archipelago, 

 Samoa and Fiji. No member of the genus has hitherto 

 been recorded from Austraha. The genus Zeuxine, as 

 defined by Bentham and Hooker f . in the Genera Plantarum, 

 absorbs Adenostylis Bl. (1825), but there seems to be a 

 tendency of late, on the part of certain botanists, to 

 re-establish Blume's genus. 



Hooker in a note on the genus (Flora British India, 

 vi. 106) states : — " The appendage between the gland of 

 the pollinia and the pollinia itself is a very curious organ, 

 and its real nature has not yet been ascertained, whether
