# Edwards's Botanical Register/Appendix to the first twenty-three volumes/A sketch of the vegetation of the Swan River Colony/Lasiopetaleae

Lasiopetaleæ.
The abundance of these plants must be taken as one of the most characteristic features of the Swan River Flora, not fewer than four genera and fourteen species of this very small group being already known as its inhabitants. Of these the greater part belong to the genus Thomasia$^{79}$ and are of little
$^{(79)}$ Thomasia stipulacea; glabra sed pilis ferrugineis stellatis bispida, foliis cordatis subhastatis angulatis obtusis sinuatis margine recurvis, stipulis magnis foliaceis petiolatis cordatis subtrilobis latioribus quam longis, racemis secundis foliis longioribus, calyce basi hispido, staminibus 5 sterilibus subulatis, petalis 0.
$^{(80)}$ Thomasia paniculata; foliis cordatis lanceolatis subhastatis pilosis subtus stellato-bispidis, stipulis foliaceis semicordatis rotundatis, racemis flexuosis multifloris foliis longioribus hispidissimis, staminibus 5, petalis 0, stylo glabro.
$^{(81)}$ Thomasia pauciflora; foliis cordatis lanceolatis subhastatis pilosis subtus stellato-bispidis nunc glabrescentibus, stipulis oblongis foliaceis semicordatis obtusis, pedunculis hispidis apice subtrifloris foliorum longitudine, staminibus 5, petalis 0, stylo basi tomentoso.—Priori affinis, sed habitu omnino diversa, et stylo racemis floribusque duplò minoribus facillimè distinguenda.
$^{82)}$ Thomasia glutinosa; foliis cordatis hastato-trilobis supra pilosis subtus stellato-tomentosis, stipulis nullis?, racemis subterminalibus erectis multifloris glutinosis pilorum fasciculis sparsè stellatis, antheris 5 rostratis, petalis 0, stylo tenui filiformi glabro basi piloso.—Flowers bright pink, large and showy.
$^{83)}$ Thomasia canescens; foliis cordatis ovatis obtusis trilobis hastatisve supra glabratis subtus ramulisque incano-tomentosis, stipulis nullis?, racemis subterminalibus erectis multifloris incanis, calycibus basi villosis, antheris 5 rostratis, petalis 0, stylo tenui filiformi glabro.—An præcedentis var. sed flores duplò minores.
(84) Thomasia grandiflora; foliis cordatis ovatis obtusis integris demùm glabris, bracteis ovatis ovalibusque obtusis integris trilobisque petiolatis, pedunculis
​interest, with the exception of T. stipulacea, paniculata, glutinosa, and grandiflora, all of which bear fine showy flowers, and deserve a place in a conservatory. Of the other genera, Corethrostylis bracteata, Endl. a downy shrub with heart-shaped leaves, is now cultivated in Baron Hugel's garden at Vienna; it bears a profusion of graceful forked racemes of crimson flowers, growing from the axils of crimson bracts, and is one of the most beautiful plants of the Colony. Sarotes ledifolia$^{85}$ is a stiff-branched shrub, with very large flowers apparently of a light blue, and small leaves not unlike those of Ledum angustifolium, but whorled in threes; like the last genus it is remarkable for having a style covered with clusters of long hairs, so as to look like a bottle-brush. Leucothamnus montanus$^{86}$ is a large bush, of rare occurrence on the mountains, with fine campanulate white flowers, at the base of which grow three leafy hispid bracts; its leaves are heart-shaped, coarsely toothed, and about the size of those of Thomasia solanacea.
Of other plants allied to Malvaceæ, there appears to be very few. A species of Rulingia is in Mr. Drummond's collection, and there are five or six fine species of Hibiscus, of which H. lilacinus of the Botanical Register, tab. 2009, is one of the handsomest. An Hibiscus, with peltate leaves, was found by Frazer growing luxuriantly on the beach; but I have seen nothing which answers to this description.
terminalibus tomentosis apice subfloris, calycibus utrinque tomentosis margine undulatis glabris, staminibus 5, stylo setaceo basi piloso.—Flowers very large, an inch in diameter.
$^{(85)}$ Sarotes. Calyx membranaceus pentagonus. Petala 5, cucullata. Stamina 5, antherarum apice elongate bilobo. Ovarium 5-loculare, loculis dispermis, ovulis superpositis; stylus supra basin scopæformis.
Sarotes ledifolia. Folia linearia, margine revoluta, obtusa, ramulisque incana, fasciculis pilorum nullis conspicuis; ternatim verticillata, forte stipulis in folia omnino mutatis. Pedunculi stellato-tomentosi, apice pauciflori corymbosi. Flores maximi cœrulescentes.
$^{(86)}$ Leucothamnus. Calyx campanulatus, bracteis 3 foliaceis basi adnatls. Petala 0. Stamina 10, altè perigyna, ad basin libera; quinque sterilibus membranaceis; antheræ fertilium cordatæ, obtusæ, longitudlnallter dehiscentes. Ovarium conicum, fundo stamineo calycis semi-immersum, ventricosum, 3-loculare; ovulis cuique loculo duobus, erectis, collateralibus; stylus setaceus glaberrimus.
Leucothamnus montanus. Frutex incano-tomentosus. Folia subrotundo-ovata, cordata, inæqualiter dentata; majora 3 pollices longa. Stipulæ semicordatæ. Pedunculi oppositifolii, apice racemosi. Calyces unciam in diametro metientes, extus hirsuti, intus tomentosi, albi, striis 5 discoloribus.
