(Continued.) 

 Helipterum Battii. 



Herbaceous, weak, papillular- and somewhat lanuginous- 

 pubescent ; leaves distant, of thin texture, from lanceolar- to 

 narrow-linear, almost flat or crisped, the floral leaves much ab- 

 breviated ; headlets of flowers small, nearly all spicately arranged, 

 singly approaching each other or some in pairs ; involucre almost 

 semiellipsoid, rayless, the constituting bracts not numerous, all 

 sessile, the lowest broad-lanceolar and largely greenish, the next 

 more scarious ; flowers few ; tube of the corofla very thin till 

 suddenly dilating ; anthers somewhat exserted ; stigmas slender, 

 with much thickened terminations ; achenes densely silky, some 

 of the inner imperfectly developed ; pappus-bristlets white, 12-14, 

 gradually less conspicuously plumous at their upper portion. 



Between Dundas-Hills and Lake-Lefroy; J. D. Batt. 



Probably not tall. Leaves seldom above one inch long, the 

 lower narrowed into a conspicuous petiole, the upper floral leaves 

 bract-like. Headlets hardly half an inch long ; the upper part of 

 their corollas emerging. Fertile achenes fully half as long as the 

 pappus. 



AUied to H. Charsleyse, but the involucral bracts are acute or 

 even acuminate and partially green-coloured, the corollas are more 

 widened towards their summit, and the pappus is pure-white. 

 The involucre brings this species near the Ixiolaenas.
