BY J. H. MAIDEN AND E. BETCHE. 151 



the Flora of N. S. Wales, we name the plant in honour of Mr. 

 Camfield, overseer of the Garden Palace grounds, its discoverer 

 in the Port Jackson district, in recognition of the zeal and 

 abilit}^ displayed by him in recent years as botanical collector and 

 observer. 



COMPOSITE. 



Helipterum microglossum, n.sp. 



A much branched woolly-white hei'b with a woolly base, 

 apparently not above 6 inches high. Leaves from linear to 

 lanceolate, sessile, the longest attaining about one inch in length. 

 Flower-heads shortly pedunculate or almost sessile, in terminal 

 crowded or corymbose clusters. Involucre nearly cylindrical, with 

 thin pale brown sparingly woolly bracts, the inner ones keeled 

 and with very short white rays. Flowers about 10 in the invo- 

 lucre, achenes silky-hairy, with about 20 pappus-bristles dis- 

 tinctly united at the base. 



Tarella, near Wilcannia, N.S.W., (W. Bauerlen, August, 1887). 



Allied to //. corymbiflorum, Schlecht., with which species F. v. 

 Mueller unites it as var. microglossum, but it differs in so many 

 essential points from the true II. cory mbijiorum, apparently 

 without any intermediate forms, that we are of opinion it should 

 rank as a species. The chief points of difference between the 

 two species are : 



H. CORYMBIFLORUM. 



Habit : erect, rather tall, with a corymbose inflorescence. 

 Involucres turbinate, with straw-coloured bracts, the inner ones 

 with rays attaining 3 lines in length. Flower's about 20 in the 

 head. 



H. MICROGLOSSUM. 



Habit : spreading, rather small, with a compact and leafy, 

 scarcely corymbose inflorescence. Involucres cylindrical, with 

 brown bracts, the inner ones with rays scarcely ^ line in length. 

 Flowers about 10 in the head.
