but ilowers of a briglit golden yellow. C. hi'cicteata^^* has 

 smaller heads, subtended by a leafy bract, and they are 

 covered with a coarse, rigid weol ; it is very near another 

 plant which answers to Brown's definition of C. aculcata, 

 from which it differs in the margins of the leaves being 

 closely serrulated, in its stem not being furnished with short 

 smooth shining scales, and in its smaller flowers subtended 

 by a leafy bract. C. dealbata"^^^ is much like the two latter, 

 but its flowers are almost gyrate rather than ca}3itate, and the 

 leaves are hoary. The remainder consist of C. setigera, 

 R. Br., and C. caricma,'^'^^ both small inconspicuous species, 

 with C. cBinula,'^*^'' which forms sedgy tufts of leaves over- 

 topping the yellow hairy heads of flowers. 



Nearly allied to Conostylis are two genera hitherto un- 

 described. The first, which may be called Blancoa^^^^ has a 

 large tubular perianth with an erect limb, and plaits between 

 the segments, included subsessile anthers, and a bony three- 

 valved capsule which is nearly superior, and bears the pla- 

 centae on the dissepiments ; this is a fine show-y plant, with
