 Rh Australia; the richest in species are Myrtaceæ, especially the curious and beautiful tribe of Chamælaucieæ, Fabaceæ or Leguminosæ, Rutaceæ, Lasiopetaleæ, Droseraceæ, Pittosporaceæ, Compositæ, Epacridaceæ, Goodeniaceæ, Styidiaceæ, Proteaceæ, Hæmodoraceæ, and Orchidaceæ; concerning each of which it is necessary to offer some special observations.

.

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 Chamælaucieæ 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. flavescens, Cunn., C. aurea, 1 (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, 2 a most beautiful plant, with hispid

 (1) aurea (Tab. III. B); strigoso-pubescens, foliis inbricatis oblongis obtusis ciliatis, bracteis margine membranaceis mucronatis tubo calycis brevioribus, aristis petalis duplò longioribus, floribus icosandris.

 (2) Calytrix sapphirina; hispido-pilosa, foliis linearibus petiolatis carinatis, caputulis sphæricis, foliis floralibus villosis, bracteis lineari-lanceolatis acuminatis margine membranaceis tubo calycis gracili brevioribus, aristis tenuissimis petalis duplò longioribus, floribus icosandris.

 (3) Calytrix breviseta; glaberrima, foliis linearibus semiteretibus obtusis mucronulatis, bracteis obovatis apiculatis tubo calycis æqualibus, aristis petalis paulò brevioribus, floribus icosandris axillaribus.—Flowers pale lilac,

 (4) Calytrix variabilis; glaberrima, foliis linearibus tetragonis obtusis minutè papillosis imbricatis nunc lineari-oblongis distractis subverticillatis, bracteis obovatis apiculatis calycis tubi longitudine, aristis ciliatis petalis paulò longioribus, floribus icosandris axillaribus.—Flowers lilac.

 (5) Calytrix simplex; ramulis pubescentibus, foliis linearibus obtusis glabris carinatis, bracteis lanceolatis acuminatis pubescentibus calycis tubo duplò brevioribus, aristis petalis paulò longioribus, floribus icosandris axillaribus.—Flowers lilac.

 (6) Calytrix glutinosa; glaberrima, foliis linearibus semiteretibus obtusis imbricatis, bracteis lanceolatis acuminatis glutinosis tubo calycis paulò brevioribus ultra medium connatis, aristis petalis duplò longioribus, floribus icosandris corymbosis.—Flowers apparently yellow, tinged with purple.
