50 VIII. CKUCIFEE^. [Bramra. 



1. B. (Sinapis) nigra (black), B,ms. Black mustard. Annual, hairy or quite 

 glabrous, especially in the upper parts, the lower leaves and stems generally 

 slightly hispid. Stems 2ft. or more high. Leaves mostly deeply divided, with 

 one large terminal ovate or oblong lobe and a few small lateral ones, the upper 

 leaves often small and entire. Flowers rather small. Pods on short pedicels, 

 closely pressed against the axis of the long slender racemes, glabrous, seldom 

 more than ^in. long, with a. slender style, slightly conical at the base, the valves 

 marked with a strong midrib. 



Hab.: Europe. A stray weed from cultivation plots in southern Queensland. 



9. CAPSELLA, Mcench. 

 (A diminutive of capsula, a capsule.) , 



(Microlepidium, P. v. M.) 

 Sepals spreading, equal at the base. Petals short. Pod ovoid or oblong, 

 laterally compressed or nearly terete, the valves very turgid or boat-shaped, 

 keeled, the septum thin ; style short or stigma sessile. Seeds several, in 2 rows, 

 not bordered, on free funicles ; cotyledons incumbent or rarely aecumbent.— 

 Small or weak annuals. Eadical leaves rosulate, entire or lobed. Eacemes 

 slender, with small white flowers. 



A small genus dispersed over the temperate regions of both the northern and southern 

 hemispheres. Two of the following species are exclusively Australian. The genus is nearly 

 allied to Blennodia, but the pod is shorter and more compressed laterally, the septum being 

 usually narrower than the transverse diameter. — Benth. 



plant little branched J to IJft. Leaves pinuatifid. Pods euneate- 

 triangular, with numerous seeds \. G. bursa-pastoris. 



Plant dwarf, beset with short hairs. Leaves linear, blunt, entire. Pod 



ellipsoid turgid. Seeds generally 4 in each cell 2. C. Andmana. 



Plant only a few inches high. Leaves divided into linear-lanceolate 

 lobes. Pod rhomboid-rotund, about 4-seeded . 3. C. humistrata. 



1. C. *bursa-pastoris (shepherd's purse), Mcench. Stems erect, from a few 

 inches to 1ft. or more high, rather rough and often hairy with a few oblong or 

 lanceolate entire or toothed leaves clasping the stem with projecting auricles. 

 Eadical leaves spreading on the ground, pinnatifid, with a large ovate or triangular 

 lobe or sometimes entire. Eoot tapering often to a great depth. Flowers scarcely 

 1 line in diameter. Pods in a long loose raceme, usually triangular-truncate at 

 the top, with the angles slightly rounded and narrowed at the base, sometimes 

 notched at the top and almost oboordate ; pedicels slender, style short, valves 

 smooth. Seeds many, 10 to 12 in each cell, oblong punctate. — Thlaspi bursa- 

 pastons, Linn. 



Hab.: Become naturalised near townships. 



2. C. Andraeana (after H. Andrs), F. v. M.; Wing's Sou. Sc. Bee, Mar. 

 1885. Annual, dwarf, erect. Stem as well as branches, flower-stalks, and 

 stalklets beset with short papillular hair. Leaves short, linear, blunt, entire, 

 glabrous ; racemes short. Flowers minute, sepals soon spreading, petals white or 

 yellowish, not or little longer than the sepals ; filaments partly dilated at the 

 base ; anthers yellowish, cordate-roundish ; stigma sessile. Pod small, ellipsoid, 

 or globular-ovate, turgid, glabrous, not divided nor dilated at the summit, on a 

 stalklet of usually the same length ; valves subtilely 1 -nerved, not keeled nor 

 much compressed ; septum lanceolar. Seeds generally 4 in each cell, ovate- 

 roundish, compressed, brown-yellowish, margined by indurated through mois- 

 ture much-expanding mucus. 



Hab.: Southern localities. 



In some respects allied to G.pilulosa, in others to C, huviistrata, — F, v. M., l.c,
