Cruciferce.] 
Xiepidium monoplocoid.es, F. 3T. in Transact. Phil. Soc. Viet. i. 35. 
Slightly rough with depressed papilla?; stem-leaves linear, entire, their base without appendages flowers 
minute, (ipetalous, tetrundvous; pedicels flat, rather stout, not much shorter than the fruit; silicic orbicular, 
acutely bidentate, quite surrounded by a broad upwards bent margin; terminal sinus extremely nairow, 
including deeply the style; seeds ovate-orbicular, strongly compressed, surrounded by a very narrow border; 
moistened testa very gelatinous; cotyledons undivided. 
In the Midlee Scrub near the Murray River, towards its junction with the Mumunbidgee. 
An erect or ascendent herb, producing several branched or simple stems from its probably annual root, 
from a very few inches to at least 1 foot high. Root slender, flexuose, hut at times stout. Leaves j-1 inch 
long, §-l line broad, radical ones unknown, being very perishable. Pedicels spreading, yet not horizontal. 
Sepals oval and oblong, i line long. Stamens minute. Filaments from a broad base subulate. Anthers 
yellow, cordate-roundish. Silicle rigidulous, l|-2 lines long and broad, slightly turgid over the space of its 
cavity; the two terminal teeth forming a short acumen; the sinus extending to near one-fourth the length 
of the valves, but being by the lateral contact of the valve-teeth generally fully closed up. Funicles very short. 
Septum narrow-lanceolate. Seeds about f line long, brown, smooth. Testa when moistened forming a 
transparent pearl of tenacious gelatine. Cotyledons semi-cylindrical, without lateral inflexion, but turning 
upwards to the radicle, thus their lower portion becoming longitudinally bent. Radicle and cotyledons 
equally' high, hut the latter considerably longer than the former. 
In flower during 1 the earliest part of the spring*. 
Xiepidium phlebopetalum. —Monoploca phlebopetala, F. JL in Linn^a, lb52, 369. 
Herbaceous; leaves linear, carnident, undivided, without basal appendages ,* pedicels racemose, as long 
as or shorter than the fruit; petals not much longer than the spreading sepals, oblong; stamens 6; anthers 
purple; silicle large, very compressed, ovate-orbicular, to one-fifth of its length acutely' hilohed, winged 
towards the apex; style capillary, free, often exserted; seeds ovate, compressed; moistened testa very- 
gelatinous; cotyledons undivided. 
In barren localities on the Murray. Also in South Australia on the Rocky Creek, and in New South 
Wales on the Darling. 
A seemingly perennial herb, a span or less high. Root flexuose, cylindrical. Stems rigidulous, simple 
or branched, often many from each root, cylindrical, slightly scabrous. Leaves J-l inch long, f-lj line 
broad, rather blunt, one-nerved. Flowers several or many in an at first corymbose, soon lengthened terminal 
raceme, which, however, never exceeds the length of a few inches. Pedicels somewhat flattened and angular, 
often scabrous, U-2h lines long, as well as the silicle spreading. Sepals oblong, greenish, with white 
margin, hardly more than 1 line or 1J line long. Petals oblong, white, tinged with purple, attenuated at 
the base, not much longer than the calyx, veined; their midnerve evanescent towards the apex. Stamens, 
at least the longer ones, reaching the height of the calyx. Filaments capillary-linear. Anthers J line long, 
oblono-, with cordate base. Pollen-grains ellipsoid, bursting longitudinally. Germen slightly scabrous. 
Style D capillan', nearly 1 line long. Pair of stigmas very minute. Silicle about 21 fines long, by the faint 
inflexion of its margin above slightly concave, imperfectly scabrous at the margin; the lobes rather acute, 
about § fine long, forming a narrow terminal sinus. Replum thick. Septum narrow-lanceolate. Funicles 
very short, subulate. Seeds brown, smooth, about H line long, surrounded by a narrow margin, when 
thrown into water evolving a copious opaque homogenous gelatine. Cotyledons somewhat longer than 
the radicle, their sutural fine extending around the basis of the seed, rendering the lower part of the 
exterior cotyledon semicircular and that of the inner cotyledon simply plicate. 
In flower during* the early part of the spring. 
This species approaches evidently not only to the following, hut also to Lepidium rotundum (Cand. 
Syst. ii. 537), Monoploca rotunda (Bunge, in Lehm. PI. Preiss. i. 260).
