App. I. Other ligneous or suffi'uticose Cnicidcece. 

 Those who wish to include in their collections all die '^^ " ^ 

 hardy plants of Cruciaceae, cultivated in the gardens, 

 which are botanically considered as ligneous, will find 

 them enumerated in our Hortus Britannicus. The 

 principal are, Cheiranthus Ckehi, and several varieties, 

 more especially C. C. fruticulosus, the wild wallflower; 

 Vesicaria utriculata ; ^lyssum argenteum, A. saxatile 

 (7%. 61.), and A. gemonense ; /beris sempervirens 

 l^g. 62.), /. saxatilis, and /. corifolia; iepidium subulatum and L. sufFru- 

 ticosum. (Sisymbrium il/illefolium, from the Canaries, might also, it is 

 possible, stand out ; and it is 

 very interesting, from its finely 

 cut leaves, a character which 

 is comparatively rare in cru- 

 ciaceous plants. All the lig- 

 neous plants of this order are 

 particularly adapted for rock- 

 work ; and, like all low-grow- 

 ing woody plants, even when 

 grown in a common border, 

 each ought to be elevated on 

 a small mound or hillock of 

 stones, of such a size as that, 

 the plant after three or four 

 years' growth, might hang 

 down over it on every side, so 

 as completely to conceal the 

 stones.
