The P ro te a c e a form perhaps th e most remarkable feature o f the Australian Flora, every species and
almost every genus found in that con tin en t and Tasmama b e in g absolutely confined to th e se countries, as
IS th e case w ith S ty lid ie a , wbich th ey outnumber many times. Upwards o f 6 5 0 Australian and Tasmanian
species are described in Meisner’s exc ellent aud careful revision o f tb e Order (published in D e Candolle’s
‘ Prodromus’ wh ilst th ese sh ee ts were passing th rou gh th e p ress), whicb is more than double th e number
known to Mr. Brown at the period o f th e publication o f b is ‘ Prodromus.’ The se be lon g to 2 5 genera, all
bu t three {Persoonia, L om a tia , and G re v illea ) o f whicb are peculiar to Australia and Tasmania, 8 are confined
to S outh-western Austraba, 4 to South-eastern, and 3 to Tasmania. Of the 6 5 0 species, upwards o f
1 9 0 are South-eastern, and 4 0 0 South-western, none, I believe, b e in g common to both quarters; there are
also b etween 3 0 and 4 0 tropical species, some o f those o f tb e north-west coast especially b e in g very sin gular
forms o f G re v illea , etc. T his aggregation o f th e most peculiar forms o f the Australian vegetation in
the S outh-weste rn quarter I have often found occasion to n otice, th ou gh it is n o t exhibited in so str ik in g
a degree by any other Order, nor perhaps is it paralleled by any similar fa ct in geographical distribution
that tbe globe presents.
T h e extra-Australian P ro te a c e a are for th e m ost part South African, whence nearly 2 8 0 have been
brought, all b e lo n g in g to genera differing from tbe Australian. Upwards o f 5 0 American species are
known, th e majority trop ica l; and 1 8 Asiatic, natives o f tbe Malayan peninsula and islands, Ceylon, and
tb e Eastern Himalaya. A very few Polynesian species have been found, and many n o doubt ex ist in N ew
Caledonia and th e n e ighbour ing groups. N o species o f the Order enters th e north temperate zone, except
in th e warm lower hills and valleys o f tb e Himalaya, and in the island o f Japan, whicb presents so many
anomalies in geographical distribution.

In consequence o f my having described young specimens o t this plant in the ' Journal ot Botany,’ in which
the leaves were not well developed, and the peduncles had not attained their full length, Meisner has separated the
Tasmanian specimens as a variety; they however differ in no respect from Australian ones o f C. taxifolium ot the
same age.— A smaU, erect shrnb, with few, slender, erect, pubescent branches, and crowded, hnear, ascending,
erect, or patent leaves, abont an ineh long. Leaves acummate, with one nerve, puhescent with silky appressed

long, each coiynihose at the apex, many-flowered. Flowers snhcapitate, white, about J inch long. jBracts ovate,
