15. B. membranacea, DC. Prodr. v. 4.40; puliescent, tall, slender, 

 znuch branclied, leaves and heads and flowers as in B. virens but more or less 

 softly pubescent, and the branches of the panicle glandular and with spreading 

 Imirs. B. hymenophyUa, DC. I. c. 440. Conyza membranacea and hymeno-

This may be a pubescent and glandular form of B. virens. The prevalent forms 

 may be approximately limited as follows. 



Vae. 1. typioa ; tall, pubescent, much branched, leaves large membranous, heads 

 many panicled. 



Var. 2. mv/ralis ; glandnlar-hairy, stem usually simple slender, leaves elliptic- 

 ovate or lanceolate toothed or serrulate very membranous, invol. bracts rigid coloured 

 like those of a Vernmia. B. muxalis, DC. Prodr. v. 440 ; Oals. ^ Gibs. Bomb. Fl. 

 126. Conyza muralis. Ham. in Wall. Cat. 3077. — Though in extreme forms the heads 

 of this look so different from those of membranacea, they are connected by numerous 

 intermediates. 



Vae. 3. gracilis; heads snbsolitary or racemose on the long slender branches. B. 

 gracilis, DC. Frodr. v. 443. Conyza gracilis. Herb. Heyne in Wall. Cat. 3064. 

 Taong-Dong in Ava, Wallich. Madras, Herb. G. Thomson. — This approaches B. 

 glomerata in habit, and may be referable to it, but the receptacle is glabrous. 



Vae. 4. Gardneri; glabrous or puberulous, erect, bright green, corymbosely or 

 paniculately branched and glandulai', lower leaves 2-4 in. lyrate or runcinate-toothed, 

 upper lanceolate sinuate-toothed, heads J in. diam. on slender peduncles, invol. bracts 

 puberulous. B. hymenophylla. Herb. Wt. {Kew Distrib. 1577). B. glandulosa, 

 Thwaites Enum. — Nilgherry Mts., Wight, Gardner ; Ceylon, Walker, &c. 



Vae. 5. viscomla, covered with lax spreading long simple and glandular hairs, 

 heads few at the ends of the few long branches of the panicle. B. viscosula, DC. 

 Prod/r. V. 441. B. lactucaefolia, var. nudipes, Kurz in Journ. As. Soc. 1877, ii. 187. 

 — Prome, Wallich; Pegu, Gomez, Kurz; Rangoon, Maclelland. 



Yas. 6. subsimplex ; anther-cells without tails, their bases connate with the fila- 

 ments. B. paucifolia and subsimplex, DC. Prodr. v. 441. Conyza subsimplex, Wall. 

 Cat. 3003. C. spiridens, Miq. Fl. Ind. Bat. ii. 44, excl. syn. — This is technically a 

 Laggera, but I agree with Kurz in regarding it as a sexual form of membranacea, 

 from which it differs solely by the anthers ; it represents closely both the larger and 

 smaller forms of memjbranacea, and is widely distributed. 



16. B. ILingrilf Clarke mss. ; pubescent and glandular above, stem strict 

 «rect simple glabrate below, leaves 3-6 in. lower petioled runoinate or lyrate and 

 unequally toothed rather membranous, heads ^ in. all peduncled in open panicles 

 with many divaricate bracteate branches, invol. bracts linear rigid green puberu- 

 lous, recept. glabrous deeply pitted, achenes 10-ribbed puberulous. 



Maewae ; Mt. Aboo, King. 



This again is closely allied to B. virens, and has similar habit and foliage, but the 

 panicle is more robust and branched, and the invol. bracts are rigid like those of a 

 Vernonia. 



17. B. Jacquemontii, Hook. f. ; villous with spreading soft hairs, 

 stem stout erect simple below, leaves 3-5 in. lower petioled obovate-lanceo- 

 late coarsely irregularly serrate upper sessile toothed or lacerate, heads ^ in. all 

 peduncled in open panicles with divaricating branches and pedicels, invol. bracts 

 numerous subulate-lanceolate rigid coloured puberulous, recept. pubescent, 

 achenes 8-10-ribbed finely silky. B. obovata ? Clarke Camp. Ind. 72 (not 

 of DC.)

A lajTge coarse species, with the paniculate inflorescence sometimes 18 in. across, 

 jellow flowers and coloured invol. scales like those of a Vernonia.
