 Russian botanist, who has communicated many observations 

 upon cruciferous plants to De Candolle.) D. C. syst. 2. p. 576. 

 prod. 1. p. 212.

 Cult. The seeds of these plants only require to be sown in 

 the open ground. A light sandy soil suits them best.

 Silique 2-jointed, 2-celled. (f. 47. c.) Style compressed, beak- 

 formed. Seeds 4, pendulous, oblong, solitary in the cells. An 

 herb with a hard woody stem. Radical leaves oblong, tapering 

 to the base, velvety with soft starry down. Floral leaves situated 

 under the pedicels, and therefore the racemes are leafy. Flowers

 Caudex woody. Flowers crowded. Sepals linear, villous on 

 the outside. Stigma acute, somewhat 2-lobed.

Cult. This plant will answer well for ornamenting rock-work, 

 or to be planted in pots and placed among other alpine plants ; 

 those cultivated by the latter mode should be planted in a mix- 

 ture of sand loam and peat, and the pots should be well drained 

 with potsherds. Cuttings planted under a hand-glass in the same 

 kind of soil will root freely, but if the plant ripen seeds, this 

 will be unnecessary. 



LXXXII. STERl'GMA (from or;piy/*a, sterigma, a fork ; 

 because the larger stamens are connected at the base, and forked 

 at the top, f. 50. a.) D. C. syst. 2. p. 579. prod. 1. p. 212.

LIN. SYST. Tetradynamia, Siliquosa. Larger stamens joined 

 to the middle (f. 50. a.). Silique roundish, at length separating 

 into many joints. Erect perennial herbs, clothed with soft starry 

 wool. Roots hard, suffrutescent. Leaves alternate, oblong, 

 tapering to the base, sometimes entire, sometimes sinuated or pin- 

 natifid. Racemes elongating as they become old ; pedicels fili- 

 form, bractless. Calyx covered with soft down. Flowers of a 

 deep yellow. Siliques covered with short dense down, often 

 interspersed with longer stiff glanduliferous hairs. 



1 S. TOMENTOSUM (D. C. syst. 2. p. 579.) leaves all sinuately- 

 pinnatifid. $ . H. Native of muddy fields towards the Caspian 

 Sea, and about the Irtish. Frequent in rubbish about towns and 



villages on the Lower Volga ; also in vineyards about Astracan, 

 more rare in the Kuman desert. Cheiranthus Caspicus, Lam.

 121. Sterigmostemon incanum, Bieb. fl. taur. suppl. p. 444. 

 Leaves less woolly than those of the two preceding species, and 

 the pods are shorter, thicker, arched, and more torulose.

Cult. These plants are well 

 adapted for ornamenting rock- 

 work, but a few plants of each 

 should be kept in pots, so that they 

 may be placed in a frame during 

 winter, and planted out in the beginning of summer in the border 

 or on the rock-work ; in fact they require the same treatment as 

 other alpine plants. They can only be increased by seeds.

 Cotyledons incumbent, folded together or plaited lengthwise 

 through their middle, and enwrapping the radical in the recess 

 (f. 45. j. f.}. Style generally enlarged, with a cell and seed at 

 its base. Seeds generally globose, never margined.
