380 LXXVIII. COMPOSITE. (J. D. Hooker.) [Tricliolepis. 



tary, peduncled, homogamous ; flowers all $ similar, fertile, yellow red or 

 purple, regular or suboblique, tube slender, limb 5-cleft to the middle. Involucre. 

 ovoid or broader ; bracts GO -seriate, very narrow, usually witli long recurved 

 hair-points or mucronate, the outer shorter ; receptacle densely bristly. Fila- 

 ments papillose ; anther-bases sagittate, auricles connate, tails slender lacerate. 

 Style-arms slender. Achenes glabrous, oblong or obovoid, smooth, ribbed, basal 

 areole lateral, terminal areole small or broad; pappus bristles oo -seriate and 

 very unequal, serrulate barbellate or feathery, long and slender or short and 

 paleaceous, or 0. DISTRIB. Species 7, all Indian or Affghan. 



* Pappus hairs scabrid, connate, not or slightly flattened below ; corolla yellow. 



1. T. Karensiuxn, Kurz in Journ. As. 8oc. 1872, ii. 318, 1877, ii. 202 ; 

 tall, erect, woody, villous above with 1-3 heads, upper leaves 3-4 in. lanceolate 

 entire or denticulate puberulous or cottony beneath, heads 2 in. diam. very 

 large bracteate by the upper leaves, invol. bracts innumerable elongate-subulate 

 spreading and incurved rigid white, recept. bristles linear equalling the feathery 

 pappus, achenes oblong 4-5-ribbed smooth, pappus hairs barbellate connate at 

 the base, outer short. Clarke Comp. Ind. 238 (T. Karensis}. 



BIRMA ; Karen hills, O'Riley $ Mason. 



Much the largest Indian species. I have seen only a very imperfect specimen, 

 and have taken the characters chiefly from Clarke : the invol. bracts are quite acicular, 

 in very many series, the inner gradually longer, innermost H in., outermost in., 

 all rigid but not pungent, densely ciliate with spreading hairs. 



2. T. furcata, DC. Prodr. vi. 563; glabrous or puberulous, branched 

 from the base, branches elongate ending in a long-pedimcled head, leaves shortly 

 petioled elliptic or lanceolate acute or acuminate denticulate covered with raised 

 points or scaberulous above and beneath or pubescent beneath, heads 1^ in. 

 nodding ebracteate, invol. bracts acicular or filiform from a lanceolate base re- 

 curved ciliate tips black, recept. bristles shorter than the narrowly oblong ribbed 

 smooth achenes, pappus hairs scabrid connate at the base, outer shorter. Clarke 

 Comp. Ind. 238. T. nigrescens, Edgew. in Trans. Linn. Soc. xx. 77. Carduus 

 trichocephalus, Wall. Cat. 2901. 



TEMPERATE HIMALAYA; from Kashmir to Bhotan, alt. 5-10,000 ft. 



Stem 2-6 ft., slender. Leaves 26 by 1^2-^ in., smooth or scaberulous above. 

 Invol. bracts very spreading in fruit; corolla f-1 in , nearly straight, yellow; anther- 

 tails subentire. Achenes I in., pale, compressed ; pappus hairs very slender, soft, inner 

 1 in., white. I can detect no character whereby to separate T. nigrescens; the amount 

 of ciliation of the bracts varies greatly. 



3. T. Stewartei, Clarke mss. ; branches rigid leafy, leaves sessile lanceo- 

 late acuminate minutely toothed quite glabrous veins indistinct, heads shortly 

 peduncled 1 in. diam., invol. bracts acicular from an ovate woolly base pale, 

 recept. bristles longer than the achenes, pappus rigid. 



PUNJAB ; in the Jhelum valley, Stewart. 



Apparently a very distinct species, of which I have seen only tips of branches with 

 imperfect flowers. Leaves 1^ in., rather coriaceous. Invol. bracts yellowish when 

 dry, inner f in. long. Pappus ^ in, long, pale, brown. 



4. T. clong-ata, DC. Prodr. vi. 563; pubescent or scaberulous, stem and 

 branches strict, leaves sessile linear oblong-lanceolate elliptic or obovate acute 

 or obtuse toothed serrate or distantly runcinate, heads -1 in. diam., in vol. bracts 

 acicular from an ovate base ciliate tips black or not, recept. bristles longer than 

 the 6-angled smooth pale achenes, pappus hairs in manv rows short, inner flat- 

 tened below. Clarke Comp. Ind. 239. Carduus elongatus, Wall. Cat. 2900, 

 2909. T. lanuginosa, Klotzsch in Eeise Pr. Wald. Sot. 79, t. 81.
