2. B, trisecta, Benth. A perfectly glabrous often glaucous undershruh 

 or almost a shrub, 1 to several ft. high. Leaves numerous, often clustered, 

 linear-filiform, sometimes rather thick, divided into 3 (rarely 2 or 5) unequal 

 linear-filiform segments, the whole leaf seldom above 1 in. long, except m 

 very luxuriant specimens. Flowers white, scented. Sepals 1 to \\ lines 

 long. Petals obovate, spreading. Fruiting raceme 4 to 6 in. long or rarely 

 more, with slightly spreading pedicels of :^ to ^ in. Pod sessile on the pe- 

 dicel, usually narrow-linear, 4 to 6 lines long, but sometimes verj^ short, 

 straight or curved, the stigma sessile or nearly so ; valves convex, with a 

 slender longitudinal nerve. Seeds numerous, small, oblong-ovoid, those 

 which T have soaked scarcely emitting anv mucus. — Sisymbrium trisectum^ F- |

Var. Iraaliycarpa. These specimens, collected in M'Douall Stuart's Expedition, are i^ 

 fruit only; the habit and foliage are precisely those of the common form gathered with them, 

 but the pods are shortly oblong and very turgid, about 2 lines long ; they may possibly be 

 accidentally abnormal. 



3. B. nasturtioides^ Benlh. A glabrous annual, the central scape 

 erect and leafless, the lateral branches decumbent at the base and leafy, fro"^ 

 2 or 3 in. to nearly 1 ft. long. Leaves usually pinnately divided into a few 

 linear rather thick segments, the radical ones often 2 in. long, the others 

 much smaller. Flowers yellow, rather small. Fruiting racemes loose, 3 to 

 6 in. long, ^-ith slender pedicels. Pod narrow, 4 to 7 lines long, nearly 

 straight and scarcely contracted at the base ; stigma sessile or nearly so; 

 valves slightly convex, the longitudinal nerve very slender and sometimes 

 qiu'te inconspicuous. Seeds small, ovate, emitting a considerable nnicus
