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

Stylidiaceæ.
The abundance of this singular order at Swan River is most remarkable. Judging from the specimens hitherto received they must be among the most common plants; indeed this Colony seems to produce a greater proportion of species than any other country yet examined. In Brown's prodromus forty-six species only are named for all New Holland, if ten are added for those of other countries, we shall have only fifty-six; but I possess from Swan River alone at least forty well marked species, and there are some of Baron Hugel's with which I am unacquainted. By far the larger part of these are plants that it would be desirable to introduce into cultivation; for, independently of the singular irritability of their column, they have in most cases beautiful gaily coloured flowers, the abundance of which compensates for their smallness; and from what we know of the very few yet in gardens, no difficulty has to be anticipated in their cultivation. Their tints are by no means confined to pink, as it would seem from those already seen in a living
$^{(121)}$ Stylidium (I. A.) leptostachyum; scapo simplici glaberrimo discolore, foliis obovatis acutis longè petiolatis, racemo simplici elongato, rachi ovariis pedicellisque glandulosis.—Flowers small, apparently white. Stem 1½ to 2 feet high, very slender, deep purple.
$^{(122)}$ Stylidium (I. A.) scabridum; scapo glanduloso-piloso decurnbente foliis linearibus reduplicatis pubescenti-scabris æquali, racemo laxo subcorymboso glanduloso-hirsuto.
$^{(123)}$ Stylidium (I. A.) caricifolium; scapo stricto glanduloso-piloso foliis lineari-ensiformibus reduplicatis pubescenti-scabris longiore, racemo sub-ramoso, rachi ovariis pedunculisque glandulosis.—Near the last, but the flowers are much larger, and the rachis &e. destitute of the shagginess of that species.
$^{(124)}$ Stylidium (I. C.) saxifragoides; foliis lineari-lanceolatis apice piliferis margine scabriusculis, scapo glabro, racemo subramoso, rachi ovario corollâque glanduloso-pilosis.
$^{(125)}$ Stylidium (I. C.) striatum; foliis obovato-lanceolatis acutissimis flabellatim venosis glabris, scapo glaberrimo glauco foliis quibusdum lincaribus prope medium approximatis et quasi verticillatis, racemo simplici, floribus eglandulosis.—Perhaps this plant should be rather stationed in Brown's section I.D., for the small leaves of the scape are almost verticillate; the leaves however are remarkably different from those of any other species. The scape is 1½ foot high; the flowers seem to be white.
$^{(126)}$ Stylidium (I. C.) bicolor; foliis linearibus mucronatis margine scabris, scapo glaberrimo aphyllo, racemo laxo subramoso, ovario rachi corollâque glandulosis.—Flowers apparently white, with a deep purple spot in the middle of the lobes of the corolla.
$^{(127)}$ Stylidium (I. C.) ciliatum; foliis linearibus ciliatis apice piliferis, scapo floribusque pilis luteis glandulosis vestitis, rachi villosissimâ, paniculâ pyramidatâ.—Flowers apparently white.
​state in Europe; for although that colour is predominant, yet we have yellow, yellow spotted with brown, and many shades of purple. Of already published species the following will be found the most striking; S. hirsutum, R. Br., whose flowers are as large as those of Lobelia heterophylla, S. pilosum, Lab., S. crassifolium, R. Br., which has a stem two feet high and S. Brunonianum, Benth., a glaucous species with verticillate leaves, and interrupted racemes of beautiful violet flowers. Of the numerous kinds hitherto undescribed, those whose characters are given below are plants exceedingly well worth cultivation.
$^{(128)}$ Stylidium (I. C.) hispidum; foliis linearibus hispidis incurvis apice piliferis, scapo glaberrimo, racemo subramoso corymboso, rachi floribusque glanduloso-tomentosis, sepalis ovatis obtusis.—Flowers white.
$^{(129)}$ Stylidium (I. D.)compressum; scapo compresso articulis 3 verticillato-foliatis, foliis radicalibus linearibus obtusis, racemo cylindraceo glauco simplici, rachi subglandulosâ, floribus glaberrimis.—Flowers bright rose-colour.
$^{(130)}$ Stylidium (I. D.) diuroides; scapo 1-articulato glabro; foliis verticillatis superioribusque sparsis; radicalibus filiformibus obtusis, racemo simplici pyramidato subglanduloso, calycis foliolis basi planis.—Flowers bright yellow, with the purple marking of Diuris maculata.
$^{(131)}$ Stylidium (I. D.) nudum; caule elongato imbricato, foliis spathulatis acutis margine denticulatis, scapo aphyllo, racemo cylindraceo simplici glandulis nigris vestito.
$^{(132)}$ Stylidium (I. D.) caulescens; caule elongato imbricato, scapo extra medium verticillo 1, foliis caulinis spathulatis acuminatis margine denticulatis scapi linearibus, racemo cylindraceo simplici glandulis lutescentibus densè pubescente.—A beautiful pink-flowered caulescent plant, nearly related to the last species, from which it differs not only in the characters above given, but also in the spike being longer and more slender, the ovaries much longer, and the whole inflorescence, instead of being glaucous, covered rather thickly with small glands upon yellow hairs.
$^{(133)}$ Stylidium (H. A.) pychnostachyum; scapo villis acutis piloso, foliis radicatibus spathulatis apiculatis ciliatis, paniculâ densâ cylindraceâ glanduloso-tomentosâ, rachi villosâ, calycibus obtusis.
$^{(134)}$ Stylidium (H. A.) canaliculatum; undique glaberrimum scapo folioso, foliis lincaribus acutis subcanaliculatis, paniculâ pyramidatâ, pedicellis glandulosis.—Flowers small, pale yellow.
$^{(135)}$ Stylidium (Centridium) androsaceum; foliis radicalibus membranaceis ovato-subortundis petiolatis subglandulosis, scapo glabro subglanduloso, cymâ simplici brachiatâ basi diphyllâ, pedunculis pubescenti-glandulosis, ovario glanduloso-scabro, corollæ calcaratæ tubo brevissimo laciniis posticis bidentatis auticis majoribus inæqualiter bilobis, labello parum minore.—A nearly leafless plant, about six inches high, with the aspect of an annual Androsace. It is nearly related to to [sic] S. calcaratum of Brown, and with it, and perhaps S. stipitatum Benth., forms a section of Stylidium, much more distinct from those called Tolypangium and Nitrangium by Endlicher than they are from each other.
