320 Notes on Indian Botany. 



Tribe VIII. Cichorace^:. 

 Sub-tribe. Scorzonere^e. Receptacle epaleaceous ; pappus 

 paleolate, paleola rough or plumose. 



93. Tragopogon, (Tourn. D. C. 7-1 12). Capitula many 

 flowered ; flowers of the ray often radiant : achaenia with a 

 lateral areola, more or less muricated, long beaked : pappus 

 plumose, five of the saeta longer and naked at the apex. 

 Biennials or perennials : roots thick lactescent : stems herba- 

 ceous erect: capitula terminal: involucrum 1-series : recepta- 

 cle epaliaceous foviolate. 



Sub-tribe. Lactuce,e. Receptacle epaleaceous or rarely 

 paleaceous : pappus hair-like, fug aceous, soft, silvery white. 



94. Picris, (Juss. D. C. 7-128). Capitula many flowered: 

 achaenia terete, attenuated at both ends, rugulose with a ter- 

 minal areola, beak none or short : pappus of the disk plumose 

 2-series, exterior shortest. Herbaceous plants : capitula 

 peduncled : involucrum 2-series : receptacle naked. 



95. Lactuca, (Tourn. D. C. 7-133). Capitula few or many 

 flowered : achaenia compressed, wingless, abruptly terminating 

 in a filiform beak. Herbaceous : capitula paniculate : involu- 

 crum cylindrical, calyculately imbricated, 2-4-series : recep- 

 tacle naked. [The essential distinction of this genus is the 

 filiform beak of the achaenia, which is most marked in the 

 common garden lettuce, but does not exist in either 

 L. glabra or L. Heyneana, the only two Indian species I have 

 examined. The former of these seems to associate better 

 with Microrhynchus ; the latter with Brachyramphus.] 



96. Ixeris, (Cass. D. C. 7-151). Capitula many flowered : 

 achaenia oblong, acutely 10-costate beaked : pappus pilose
