A stout branched shrub, succulent when near the sea. Leaves 1-1^ in., very 

 variable in breadth, from - in. Heads ^-^ in. diam., quite different from those of 

 the preceding species, both as to structure and arrangement. 



7. P. linearifolia, Clarke Comp. Ind. 95 ; annual, scaberulous, leaves 

 sessile very long linear rigid coriaceous margins recurved toothed, heads 

 clustered at the ends of the long branches of the corymb, outer invol. bracts 

 rounded. 



ASSAM, Masters. MISHMI at Jingsha, on the Karam in sandy places, banks of the 

 Lohit below the Dihong (and ? KHASIA MTS.), Griffith. 



Stem apparently 2-3 ft., simple below, slender or stout, sometimes as thick as the 

 little finger, corymbosely branched above. Leaves 5-8 by -^ in., sessile by a broad 

 base, midrib very stout, nerves very obscure. Corymb very scabrid, branches naked, 

 stiff, erecto- patent. Heads % in. diam. ; invol. bracts scaberulous. Achenes not seen ; 

 pappus snow-white. This is a very curious plant, clearly annual, and differing wholly 

 in habit from the preceding but agreeing in the heads and flowers. A ticket with 

 "Khasia" on it is amongst Griffith's specimens, but no other collector has found it 

 there, and the ticket is probably misplaced.

 been found hitherto within the British border, it is a viscid Siamese shrub, with 

 petioled linear coarsely toothed leaves and corymbs of small heads with broad ovate- 

 lanceolate invol. bracts. 



29. NANOTHAMNUS, Thorns. 



A small rigid woolly herb. Leaves alternate, acutely serrate. Heads small, 

 subsessile, subterminal and axillary, heterogamous, disciform ; outer fl. 1-4, $ , 

 (rarely 0), filiform, 2-3-toothed, fertile; d'isk-fl. $ , few, fertile, tube slender, 

 limb campanulate sub-2-lipped, outer lip 4-lobed, inner free to the base. 

 Involucre ovoid ; bracts oo -seriate, lanceolate, dry, inner sub-scarious, outer 

 shorter hispid ; receptacle flat, naked. Anther-bases sagittate, auricles mucro- 

 nate or shortly tailed. Style-arms of g filiform. Achenes obovoid, tip rounded, 

 ribs 5-8 slender ; pappus or a minutely 5-toothed crown. 



N. sericeus, Thorns, in Journ. Linn. Soc. ix. 342, t. 3 ; Clarke Comp.

The CONCAN, on dry hills, Dalzell, &c. 



Soot stout, fusiform, woody, annual ? Stems very many from the root, decumbent 

 or suberect and ascending, 6-8 in. long, pale, rigid. Leaves ^-2 in., lanceolate, sessile 

 or contracted into a petiole, rigid, pungent and with irregular pungent teeth, strongly 

 nerved and reticulate. Heads % in.; in dense clusters. This curious plant bears some
