Melampy 



ramis 



ovato-lanceolatisve acuminatis glaberrimis, floralibus subsimilibus 



scaberulis, racemis laxis, floribus pedicellatis puberulis, calycis den- 



tibus tubo subajquilongis corollae tubo angusto multoties breviori- 



bus, capsula ovato-lanceolata acuminata. (Tab. VIII.) 



Hab. In apricis montibus Khasize, alt. 5-6000 ped.— (Fl. September.) 



The occurrence of a genuine species of Melampyrum in Eastern 



Bengal, and at a moderate elevation above the sea, would of itself be 



a sufficiently remarkable fact, but is rendered in the present case all 



the more so, from the genus not appearing elsewhere in any part of 



India; it has neither been detected in Afghanistan or Tibet, where 



European genera prevail, nor hitherto in China, where all the other 



temperate Khasian forms, which are not European or Himalayan, are 



found. Several species inhabit the Caucasus, which is the eastern 



limit of the genus in Central Asia ; and one. M. cristatum* inhabits the 



M. 



America. The M. 



small 



half 



of a leaden blue when dry. The structure of the calyx, corolla, sta- 

 mens, ovary, curious ovules, and seeds, is precisely in all points as in 

 the European species. It is a very local plant in the Khasia, but most 

 abundant where found.

Throughout the province of Guzerat there grows a singular-lookin 

 Cissus, which I have not seen in any other part of India, and which,
