64. viii. crucifeiue (olivee). [Sisymbrium. 



2. S. Pumilio, Oliv. A low, often rather tufted annual, more or less 

 hispid below. Leaves chiefly radical and rosulate, spathulate- or linear-lan- 

 ceolate, entire or broadly toothed. Flowers minute. Siliquas narrow-linear, 

 more or less spreading.— Cardamine pusilla, Hochst. in PI. Schimp. Abyss. 



Nile Land. Abyssinia, mountain summits, Schimper ! 



I have not snen satisfactory specimens of this plant, which may prove a form of some 

 other species. The specific name I am obliged to change under Sisymbrium, as it is already 

 occupied. 



3. S. falcatum, Fount. Recherches Cracif. 135. Tufted and branched 

 at the base. Stems about 6 in. tall, erect or ascending. Leaves all or nearly 

 all radical, pinnatifid, with the terminal lobe usually larger, lateral lobes ob- 

 tuse or acute, sparsely pubescent or nearly glabrous, narrowed into rather 

 long linear petioles. Flowers rather large. Siliquas narrow-linear, spreading 

 or ascending, longer than the pedicels. — Braya falcata, Hochst. in PL Schimp.

I follow Dr. Hooker in referring this plant to Sisymbrium ; M. Fournier refers it witfl 

 doubt. 



4. S. erysimoides, Deaf. ; DC. Syst. Veg. ii. 482. A glabrous an- 

 nual of 1-3 ft., simple or branched. Leaves lyrate-pinnatisect or, at least 

 the upper, with the lobes confluent more or less and ovate-lanceolate, va- 

 riously toothed. Racemes elongate, many-flowered. Pedicels of fruit about 

 1 line. Siliquas divergent, rigid, linear-subulate ; valves 3-nerved ; beak 

 short.

A wide-spread plant in the Mediterranean region. I have not seen Abyssinian speci- 

 mens myself. 



5. S. Irio, Linn.; DC. Syst. Veg. ii. 467 (var. maximum). An erect 

 more or less branched herb with a smooth stem, glabrous or, in the African- 

 plant, sparsely pilose, at least below. Radical leaves oblanceolate, pinnati- 

 partite, with spreading, rather acute segments or subruncinate. Cauline 

 leaves narrow-lanceolate, the teeth or segments towards the base usually 

 larger and deeper, usually shortly petiolate. Racemes elongate, l ea ^ sS * 

 Plowers small. Siliquas "elongate, very narrow-linear, rather flaccid at firs^ 

 and subtorulose, spreading, l±-2 in. or more in length, on pedicels of ft 

 in. Seeds oblong, under a lens very minutely granulate.— & maximum, 

 Hochst., Fourn. Recherches Crucif. 72'. 



Nile Land. Abyssinia, Schimper ! . . 



Widely spread in Southern Europe and Western Asia, extending eastward to the Pu n J a ' 

 westward to the Canaries. Specimens from the latter islands closely resemble the AbJ 

 sinian plant. Is not S. capense, Thunb., referable to the same species ? 



6. S. abyssinicum, Fount. Recherches Crucif. 71. Annual,/ 1 * 

 sparse," spreading, rigid hairs, attaining 2-3 ft. Leaves sessile, runcinaW. 

 glaucescent, thinly hairy. Pedicels ascending, about equalling the flowers, 

 at length 6-7 lines. Siliqua torulose, rigid, compressed, 2 in. long, rostrate; 

 valves 3-nerved.
