Stenopetalum velutinum— p. 49. 
Extends to the upper tributaries of the Darling- River. 
In summing- up the Cruciferous plants of Australia (conf. p. 51) we have to add the Western Australian 
Geococcus pusillus (Harvey, in Hook. Kew Misc. vii. 52), also Lepidium strong-ylophyllum and Thlaspi 
ochranthum from the Darling- Desert, the two latter as yet imperfectly known.

Xonidium Vernonii.—Herbaceous, glabrous, stem simple or not much branched, angular; leaves 
all alternate , lanceolate- or broad- or narrow-linear, entire; stipules extremely minute, clavate-filiform; 
peduncles axillary, one-jlowered, about as long as the pedicel, many times shorter than the flower, bibracteolate 
at the summit; sepals semilanceolate, acuminate; paired petals blunt , scarcely longer than the calyx, the 
upper ones one-nerved, all several times shorter than the blue orbicular or broad-ovate unguiculate labellum ; 
anterior filaments with a globular gland; anthers terminated with two exceedingly minute teeth. 
On barren plains and ridges near the Genoa River; also near Twofold Bay, and according to Mr. W. 
Woolls and Mr. W. Vernon likewise to be found near Port Jackson. 
Root perennial, cylindrical, pallid, finally divided into flexuose branches. Stems generally numerous, 
sometimes few or one, especially upwards as well as the branches remarkably angular, occasionally somewhat 
scabrous, already flowering- during the first year of growth. Leaves §—1J inch long*, 2 lines broad, sessile, 
one-nerved, tapering* into the base and the apex, very faintly veined, flat or very slightly at the margin revo¬ 
lute ; rarely some cuneate-obovate; the lower ones early falling; the floral leaves sometimes much reduced 
in size. Stipules almost gland-like, only about \ line long. Flowers constituting- along the summit of the 
branches a short leafy raceme. Peduncles 1-2^ fines long, angular, persistent. Pedicels often arcuate, 
furrowed, deciduous. Bracteoles membranous, semilanceolate, finely one-nerved, about J fine long, persistent, 
glabrous. Sepals about 1J fine long, finely three-nerved, broader and narrower semilanceolate. Lower pair 
of petals quadrate-ovate, 1J-2 fines long, finely five-nerved; upper pair about 1 fine long-, nearly ovate. 
Labellum finely flabellate-veined, about J inch long-, tapering into an unguis and short saccate base, there 
bicarinulate and slightly bearded. Staminal glands greenish, smooth. Filaments extremely short, narrow, 
flat, glabrous. Terminal appendage of the anthers orange-colored, membranous, glabrous, semiovate; cells 
of the anthers elliptical; connective outside slightly dow’ny. Style glabrous, about § fine long, clavate- 
filiform, geniculate at the base. Stigma truncate. Ovary almost spherical, smooth. Fruit as yet unknown. 
Gingins’ short diagnosis of Pigea filiformis responds fully to the plant here described. But since all 
subsequent writers on these plants, except Don (Gen. Syst. of Diehl. Plant, i. 336), combine I. filiforme with
