THE CABBAGE FAMILY. 119 



Parsley-family; but in that the leaf-stalks are hollow, and the leaflets serrated, 

 whereas in the water-cress, the stalks are solid, and the leaflets entire. Brook- 

 lime, a pungent plant, often found and gathered with water-cresses, and which 

 may be eaten with safety, has simple and undivided leaves, growing in opposite 

 pairs, and the flowers, in their season, of a brilliant azure. 



18. Land Yellow-cress — (^Nasturtium terrestre.) 

 In waste places, especially where water has stood, common. Very 

 abundant about Disley. Fl. June — September. Annual. 



Curtis, ii. 3-41 ; E. B. xxv. 1747 (as Sisymbrium terrestre). 



19. Water Yellow-cress — (Nasturtium ampMbium. 

 Pondsides between Old Trafford and Stretford, rare. Ponds behind 

 the Art-Treasures building site. Fl. July, August. 



E. B. xxvi. 1840 (as Sisymbrium dmpMbium). 

 The leaves of the submerged branches often become deeply pectinated, as hap- 

 pens with those of the water snow-cups, and with many other semi-amphibious 

 plants where ihe structure of the leaves is favourable to it. 



20. Hedge-mustard — {Sisymbrium officinale.) 

 Roadsides, and on dry, parched hedgebanks, everywhere, loving 

 drouth and dust, which latter it seems to have a peculiar aptitude for 

 collecting. Fl. June, July. 



Curtis, ii. 342 ; E. B. xi. 735 (both as Erysimum officinale). 



A singular plant, readily distinguished by its pyramidal figure ; long, rigid, 

 outstretched, horizontal branches, leafless at the end ; little terminal clusters of 

 minute flowers, and pods in a line with the stem. 



21. Worm-seed — {Erysimum cheiranthoides.) 

 Fields and hedgebanks near the Mersey, between Rixton and 

 Carrington, and between Barton and Irlam ; in the latter place as 

 plentiful a few years ago as if handfuls of seed had been thrown 

 broadcast, but now much reduced in quantity. Found also on the 

 edge of Chat Moss, at Astley, and near Ladywell Brow, Worsley. 

 (J. E.) Fl. July, August. Annual. 



E. B. xiv. 943 ; Baxter i. 62. 



22. Garlic White-cress — Allidria officinalis.) 

 Hedgebanks, shady lanes, and waste places, everywhere. Fl. May, 

 June. Annual. 



Curtis, i. 121 ; E. B. xii. 796.
