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) Calytrix 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.

spreading heath-like leaves, and round heads of very deep violet; all the others are pretty, and worthy of cultivation, although not so strikingly beautiful as those just mentioned. Still more remarkable than these is the magnificent Chysorrhoë nitens (Tab. I.), whose yellow flowers of metallic lustre form masses of golden stars some feet in diameter; this plant, which I described some years since (Companion to Botanical Magazine, vol. ii, p. 357), is a small bush, and certainly one of the most interesting species that could be introduced; by Dr. Endlicher it is reduced to the genus Verticordia, but I think the character assigned to it in the work alluded to is sufficient to define the genus; a comparison of Tab I. and Tab. II. A. will sufficiently explain in what the difference consists between Chrysorrhoë and Verticordia. To the former of these genera there is a new species to add, not less beautiful than the original, but with obovate serrated leaves, on which account it may be called Chrysorrhoë serrata.8 The Verticordias are bushes with small, usually heathy, very fragrant, leaves, and corymbs or racemes of white, pink, or yellow flowers; several species have been already described, among which V. insignis, Endl. (Tab. II. A) is one of the commonest and prettiest; to these I have to add V. heliantha,9 a lovely plant with corymbs of large deep yellow feathery flowers; V. acerosa,10 a species resembling the last in habit, but with acerose leaves and smaller paler flowers, which change in drying to a bright deep green; and two species11 with pretty white or blush ones. Of the genus

Lhotskya, there are two species, one, L. acutifolia,13 with an abundance of pale axillary yellow flowers, and the other L. violacea,14 with bright lilac flowers in heads. In addition to these the Colony produces three species of a curious little genus, with inconspicuous flowers, closely related to Genetyllis, which, from the exquisite sweetness of its foliage, I propose to call Hedaroma.15 The leaves, or rather the half-ripe fruits, of those plants preserve their fragrance so well that they might be worth collecting for the use of the perfumer; and if so they would furnish a new and most agreeable article of luxury to Europe, and a small aid to the natural resources of the Colony.

Among the Myrtaceae with polyadelphous stamens there are many remarkable species. Mr. Frazer frequently men-

B); foliis ovato-oblongis subtus glandulosis: involucrantibus latioribus coloratis, filamentis sterilibus truncatis, stylo apice barbato.—It is possible that this may be the Genetyllis citriodora, Endl. but that plant is described as having from 4 to 5 ovules, while H. latifolium has certainly only 2.

tions the beauty of the species of Melaleuca, of which there is a great variety, some of which are handsomer than any yet in our gardens. Melaleuca seriata,18 parviceps19, and trichophylla,20 are bushes, every twig of which is terminated by hemispherical heads of a brilliant pink; M. callistemonea21 has all the beauty of a red-stamened Callistemon; M. striata, Lab., and Hugelii, Endl., and viminea,22 a species near M. armillaris, have spikes of white; M. spinosa23 forms a spiny bush, with oval spreading leaves and slender spikes of yellow; and M. Radula24 is a shrub with long linear leaves, rough with tubercles, among which are scattered a few fine lilac (?) flowers, with a large capitate stigma, and stamens disunited almost to the base of their phalanges; this latter species seems to form a passage from the genus Melaleuca to that of Metrosideros. Amongst the specimens sent home by Mr.

(18) Melaleuca seriata; foliis alternis linearibus obtusis subtus glandulis 2-seriatis ramulisque glabris, capitulis densis hemisphæricis, phalangibus oligandris: unguibus petalorum longitudine, calycibus glabris, rachi lanatâ.—Flowers rich rose-colour.

Drummond occur a few twigs of a plant with narrow lanceolate leaves, and cone-like spikes of yellow (?) flowers, which bears to Melaleuca the same relation as Beaufortia to Calothamnus; that is to say, it differs in having the fruit only three-seeded instead of many-seeded; to this plant, which is more curious than beautiful, the name of Conothamnis trinervis26 may be given. Of the splendid genus Calothamnus there are four species; of which C. sanguinea, Lab., and C. eriocarpa,28 are remarkable for the abortion of a part of their stamens, and the combination of the remainder into an irregular sheath slit on one side; C. purpurea, Endl., rivals the crimson Callistemons in appearance; while the C. lateralis27 has long terete leaves and rows of flowers, so imbedded in long lines on one side of the branches, that only the tips of the calyx and the long blood-red stamens can be seen beyond the bark in which the inflorescence takes its rise; in this case the inflorescence is so peculiar as to deserve to become the subject of special enquiry. To these forms have to be added some shrubs which constitute a group not perhaps distinct from Beaufortia,29 but distinguished from that genus, as represented by B. decussata, by their capitate inflorescence, and by having the dehiscence of their anthers lateral rather than vertical. Of these bushes, all of which are extremely

Beaufortia (Schizopleura) Dampieri (Beaufortia Dampieri, A. Cunn.)

pretty one, B. purpurea,30 figured in this sketch (Tab. III. A), has globose heads of deep purple flowers; and another, B. macrostemon,31 has them of what seems to be a rich scarlet, with a tasselled appearance, owing to the great length of the phalanges of stamens.

Of the Myrtaceæ with distinct stamens the species of known genera are numerous, but not in general so handsome as those already mentioned. There is one species of Callistemon,32 with rich crimson stamens, which is perhaps the finest of the genus. Frazer speaks of two Metrosideros, growing on the beach, the fragrance of which exceeded any thing "he ever experienced;" and there are several Bæckeas, Leptospermums, and similar plants. Of the latter, however, the only interesting species are Agonis33 linearifolia and flexuosa, DC., bushes with knots of white flowers; Hypocalymna robusta, Endl., which has clustered flowers, the colour and size of Peach blossoms; and a Pericalymma or two, which probably will prove pretty plants. Of unpublished genera there are two, one of which, Salisia pulchella,34 has large

(30) Beaufortia (Schizopleura purpurea; (Tab. III. A) foliis rameis imbricatis lineari-lanceolatis carinatis obtusis basi 3-nerviis, floralibus cordato-ovatis trinerviis marginatis, phalangibus hexandris basi pubescentibus, capitulis globosis.

(31) Beaufortia (Schizopleura) macrostemon; foliis linearibus obtusis planis vel lanceolatis trinerviis marginatis patentibus ramulisque pilosis, phalangibus elongatis 3–4-andris basi villosis.

(32) Callistemon phœniceum; foliis lineari-lanceolatis coriaceis mucronatis basi angustatis marginatis aveniis cortâ obsoletâ, calycibus glabris.—Flowers very rich deep crimson.

(33) This name, published by DeCandolle in 1828, was altered by Dr. Brown in 1830 to Billottia, the designation given by Colla, under a mistake, to some of the species of Calothamnus. As the change is apparently altogether arbitrary, I make no scruple about restoring the nomenclature of De Candolle.

(34) Salisia. Calyx omninò superus, campanulatus, 5-dentatus. Petala 5, membranacea, colorata. Stamina 00, æqualia, annulo inserta; antheræ oblongæ, biloculares, dorsifixæ. Ovarium 6-loculare, omninò inferum; loculis polyspermis, per rimas totidem in fundo calycis elevatas sub anthesi etiam dehiscentibus; stigma subcapitatum.—Flores corymbosi aut racemosi.

Salisia pulchella. Ramuli pubescentes. Folia alterna, obovata, plana, acuta, coriacea, obsoletè trinervia, pubescentia. Flores speciosi, in racemis corymbisque laxè ordinati. Calyx hemisphæricus, 2½ lineas latus, tomentosus, dentibus ovatis acutis. Petala subrotunda, concava, amænè rosea, ciliolata, 2½ lineas longa. Stamina 6 lineas longa, et ultra, numerosa. Calycis

deep purple flowers, with long stamens, and must be a most striking object; it is probably rare, as I have only seen two or three small fragments; it is characterized by having, at the bottom of its superior hemispherical calyx, six elevated clefts, which appear as if they were the united sides of so many inflexed valves, between which there is a passage directly into the cavities where the ovules lie; I am not however sure that this is the real nature of the structure. The other has the structure of a Melaleuca, in a slight degree, but the stamens are irregularly polyadelphous, or altogether distinct, the anthers are fixed by their base and not their back, and the flowers grow singly at the ends of the branches, where they are covered with imbricated bracts. Of this genus, which may be called Eremæa35 (ερεμαιος, lonely), there are three species, of which the only pretty kind is E. fimbriata; E. pilosa is probably the plant named Metrosideros pauciflora by Endlicher.

Of Eucalypti there must be many species, but I have no materials sufficient to ascertain what they are; the barren hills on the bank of the river at Point Frazer are said to produce the magnificent Eucalyptus calophylla, but as that plant is not defined I am not sure whether I possess it or not.

tubus intus glaber, in fundo rimis 6 ovarii loculorum dehiscentibus stellatis elevatis interruptus.

(35) Eremæa. Calyx 5-dentatus, semiinferus, campanulatus. Petala 5.

(38) Eremæa fimbriata; ramulis pubescentibus, foliis oblongis concavis obtusis imbricatis pilis longis fimbriatis subtrinerviis reticulato-rugosis, bracteis calycibusque tomentosis, staminibus petalis 3-plò longioribus.—Flowers rich purple.
