(Continued from ijage 60'2 of Volume XX.) 



We now finally arrive at the species comprised in Tribe IV, 

 O'phrydece, of which the general characters were given on p. 433 

 (Vol. XVI). 



In the Flora of British India all the Bombay plants comprised 

 in this Tribe have been aggregated under the generic title of 

 Habenaria. Dr. T. Cooke, in his recently published Flora of 

 Bombay, has, however, subdivided them into three genera, and as 

 his work will probably be the text book for many years to come, 

 it may be most expedient for us to follow his example. 



The characters of his three genera are shortly, terrestrial, tuber- 

 ous herbs, leaves membranous or fleshy. 



* tSepals subequal and more or less conni- 

 vent ; petals equal to or shorter than the 



sepafe 29. Peristylus. 



** Sepals unequal, the lateral more or less 

 spreading. Stigmas sessile or subsessile, 



confluent or more or less distinct 30. Platanthera. 



Stigmas more or less distinctly stalked, 

 very rarely confluent 31. Habenaria. 



29. Peristylus. 



Terrestrial. Flotvers in spiTiSS terminating the leafy stems, 

 ■sepals and petals subequal, often connivent, lip continuous with the 

 column, produced at the base into a short spur, cohmm short ; anther 

 ■cells parallel; apex inferior, short and adnate to the base of the 

 column ; pollinia granular with short caudicles and exserted naked 

 glands ; staminodes lateral, auriculate ; stigma sessile ; rostellmn ser- 

 rulate or tooth-like, situated between the anther cells.
