Tliis species has always been confused with A. bicuspidafum J. J. S. 

 (Appendiculd callnsa Bl., A^rostophyllum stipulatum Schltr. p. p.). It dif- 

 fers iii the sinaller leaves, smaller white flowers, the form of tlie calliis 

 of the lip aiid coliimii arms, the quadrate stigma, etc. 



It is certainly very near to what Griffith describcd aiid figured as 

 Appendiciila callosa and Appendiciila stipulaici, but as I hâve not seen spé- 

 cimens, Griffith 's figures show some différences and it seeins that Grif- 

 fith 's name includes two species (see my leniark under Agrostophyllum 

 bicuspidatum J. J. S. in Bull. Jard. Bot. Buit. ined,), 1 thought it préférable 

 to publish tlie plant as a new species. 



Description from severai cultivated plants. 



The forms witii a nearly white lip and those with the centre of the 

 lip spotted purple are native from Banka.
