Nearest to G. parvifiorum, Wall., but with a much smaller calyx with diminutive 

 teeth and a much narrower corolla. G. parvijlorum, though stated by Bentham, 

 Miquel, and Hooker to occur in Penang, has never been met with in our area. 

 The specimens on which the statement is based were collected by Wallich, who in 

 1828 issued them as the types (Lith. Cat. n. 2159-1) of his own species G. crinitum, 

 to which they most undoubtedly belong. A year later Wallich referred these same 

 specimens (as n. 21o8-c) to his own G. pannjiorum ; this quite erroneous afterthought 

 has been accepted by the three authors referred to. 



2. GoMPHOsTEMMA CRINITUM, Wall. Cat. 2159 (1828). A coarse 

 perennial herb, 3 to 4 ft. high. Steins stout, erect, sulcate, M^oody,
