1 BLENNODIA canescens

LOC In arenosis depressis

DESC Suffruticosa, sesquipedalis, caule ramisque teretibus Folia vix pollicaria paucidentata Racemi multiflori, erecti, ebracteati Flores albicantes Calyx incano-pubescens Petaloruiores Stamina 6, tetradynaustato

OBS This plant has entirely the habit, and in many important points the structure of Matthiola, near which in a strictly naturalincu of its seeds Thethe whole surface of the testa, each containing a spiral fibre, which seems to be distinct from the membrane of the tube A structure essentially sienerally in several faenera of Cruciferae it may exist, I have not ascertained; it is not found, however, in those species of Matthiola which I have exaenus, proximum Gossypio, affine etiaerrimum Calyx 5-dentatus, sinubus rotundatis Petala cuneatoobovata, basi inaequilatera Columna stamata distincta linearia PericarpiaSelaber; foliis petiolatis obovatis integerrimis; floribus pedunculatis solitariis

2 STURTIA Gossypioides

LOC ”In the beds of the creeks on the Barrier Range”--D Sturt

DESC Suffrutex orgyalis glaber Folia ramorum alterna, diametro unciali, trinervia; petiolo folium subaequanti, basi in stipulam subscariosam adnatam dilatato Pedunculi vel potius rami floriferi suboppositifolii nec vere axillares uniflori, juxta apicem folio nano petiolato stipulis 2 distinctis stipato instructi Involucrum foliaceuricantibus glandulosis conspersis Calyx dentibus acutis, sinubus rotundatis Petala sesquipollicaria, uti calycis tubus glanduloso-punctata glandulis nigricantibus seine barbatis Columna staminum e basi nuda super ad apicem usque antherifera: antheris reniformibus, loculis apice confluentibus Pollen hispidum

OBS Sturtia is no doubt very nearly related to Gossypium, from which it differs in the entire and distinct leaves of its foliaceous involucrum, in the sharp teeth and broad rounded sinuses of the calyx, and possibly also in its fruit and seeds, which are, however, at present unknown They agree in the texture and relands of the calyx, and in the structure of the columna staminum Senra, which like Sturtia, has the foliola of its three-leaved involucru its calyx 5-fid with sharp sinuses, in the absence of glands, in the reduced number of stamina, and in its dispermous ovaria

3 TRIBULUS (Hystrix) lanatus, foliis 8-10-jugis, fructibus undique tectis spinis subulatis longitudine inaequalibus: itudinem cocci superantibus

LOC ”In collinis arenosis Lat 26 degrees” D Sturt

DESC Herba diffusa, sericea, incana Foliuni Calyxaestivatione leviter iiora Stamina decem, antheris linearibus

OBS I A species nearly related to T Hystrix, found on the west coast of Australia, or on souished by the following character Tribulus (occidentalis) sericeolanatus, foliis suboctojugis, coccis undique dense aritudine invicem aequalibus These two species differ from all others in the uniform shape of the spines, which equally cover the whole external surface of the fruit

OBS II The Auishable fro ten monosperlands subtending the 5 filainally separated as a genus by Scopoli, under the name of Kallstroemia, which has been recently adopted by Endlicher

Another tribe exists in the intratropical part of the Australian continent, to which, nearly 40 years ago, in the Banksian Herbariueneric nauished by the following characters
