 curious and beautiful tribe of ChamcBlauciecBy Fahacem or

 of which it is necessary to offer some special observations. 



Myrtaceje. 



Of this extensive order, of which the Australian forms 

 are so numerous and very peculiar, the Colony contains a 

 large number of species, among which the Chamcelauciece are 

 extremely interesting. These chiefly consist of bushes, with 

 small heath-like leaves, and white, yellow, or purple flowers, 

 of great brilliancy, more or less collected into heads. 

 Although scarcely noticed in the reports of either Brown or 

 Frazer, they form a most striking object in the vegetation. 

 Of the genus Calytrix alone there are ten species in my 

 collection ; the three most remarkable of which are C.jiaves- 

 cens, Cunn., C. aurea,^ (Tab. III. B), with oval imbricated 

 leaves and heads of the brightest yellow flowers, whose sepals 

 end in awns, at first yellow but afterwards olive-green; 

 and C. sapphirina,^ a most beautiful plant, with hispid

(2) Calytrix sapphirina ; hispido-pilosa, foliis linearibus petiolatis carinatis, 



capitulis spha3ricis, foliis floralibus villosis, bracteis lineari-lanceolatis acii-
