FROM UPPER BURMA AND THE SHAN STATES. 79 
receptaculum parvum, nudum; ligule 5-dentate.  Achenia 
minuta, fusiformia, glabra, leviter pauci-costata, apice constricta ; 
pappi setz albæ, molles, fere obsolete, scaberule, quam achenia 
duplo longiores. 
Shan hills at 4000 feet. 
This very closely resembles C. glauca, Hook. f. (Fl. Brit. Ind. iii. 
p. 394), nct of Torrey and Gray, a native of North-west India, 
described as an annual, though some of the specimens seem to 
indicate a plant of longer duration. ©. chloroclada differs in the 
hairy involuere and relatively much shorter achenes, constricted 
at the top, and having fewer, less conspicuous ribs. 
Lactuca polycephala, Benth.; Fl. Brit. Ind. ii. p. 410.— 
Shan hills plateau at 5000 feet. 
Afghanistan to Khasia and Burma. 
Lactuca gracilis, DC.; Fl. Brit. Ind. ii. p. 410.—Shan hills 
at 4000 to 5000 feet. 
Nepal to Central China. 
Lactuca sagittarioides, Clarke; Fl. Brit. Ind. iii. p. 410.— 
Shan hills at 5000 feet. 
Western Himalaya to Upper Burma. 
Lactuca alatipes, Coll. et Hemsl., n. sp. 
Herba robusta, glabrescens, caulibus crassiusculis lævibus. 
Folia caulina inferiora membranacea, longissime petiolata, petiolo 
alato, trilobata, usque ad 14 poll. longa, lobo terminali amplo 
sagitto-hastato obscure multilobato simul remote calloso-den- 
ticulato, lobis lateralibus terminali distantibus parvis vix polli- 
caribus rotundatis. Capitula laxe paniculata (ramulis peduncu- 
lisque squamoso-bracteatis gracilibus), erecta, circiter 9-flora ; 
involucri calyculati bracteæ circiter 9, uniseriate, glabræ, lineari- 
oblong, semipollicares, obtuse.  Achænia rubescentia, angusta, 
valde compressa, faciebus prominenter 4-5-costatis, ceterum 
lævia vel minutissime setulosa, longe gradatimque rostrata, 
circiter 3 lineas longa; pappi sete numerosissimæ, albæ, molles, 
minutissime setulosæ, achænia triente longiores. 
Shan hills terai at 3000 feet. 
Apparently a very distinct species similar to Z. hastata, DC.
