flowers had the usual appearance, except that the stamens were changed into 

 petals ; and on opening the ovarium of the highest blossom no ovules were disco- 

 verable amongst the mass of petaloid laminse with which the cavity; was filled. 

 Ihe lowermost pedicellate pods had doubtless been at first surrounded by the 

 regular floral envelopes, but from some cause had not emitted them at the sutures 

 like the rest. From their verticillate arrangement it is evident that these petaloid 

 expansions were not transformed seeds, but simply a development of the common 

 axis within the ovary into an abortive whorl of floral organs, besides which there 

 were evident rudiments both of stamens and germen in the centre of the bundle. 



2. G. hirsuta, L. Hairy Bitter-cress. "Leaves all pinnate 

 ■without auricles, radical leaflets roundish-angled or toothed petio- 

 late, stem-leaflets narrower nearly sessile, petals oblong, stigma 

 blunt, pods erect." — Br. Fl. p. 27. 



On hedgebanks, walls, rocks, in woods and moist shady places, abundantly. 

 Fl. March— August. Q. 



From 3 inches to a foot high, according to the wetness of the situation. The 

 whole plant, especially the root, has an extremely strong pungent smell of Horse- 

 radish, and might if cultivated furnish an excellent salad-herb and antiscorbutic. 

 Not uncommonly the plant is quite smooth except a fringe of hairs aloijg ihe 

 edge of the leaves.

" Pod 4-sided or 3-edged. Stigma nearly sessile ; the lobes 

 elliptical, connivent. Calyx erect." — Br. Fl . 



1. H. matronalis, L. Common Dame's Violet. " Stem erect, 

 leaves ovato-lanceolate toothed, limb of the petals obovate, pods 

 erect torulose, their margins not thickened." — Br. Fl. p. 33. H. 

 inodora, L. : E. B. t. 731. 



In meadows and pastures, very rare and probably the outcast of gardens. Fl. 

 May— July. 2^. 



E. Med. — Near Bonchurch, sparingly, Mr. D. Turner in B. T. W. I have 

 not succeeded in finding the plant at the above station, but my friend Mr. Cuilis 

 has gathered specimens there within these few years, from wlieuce his drawing in 

 Br. Entom. was taken. 



VIII. Sisymbrium, Linn. Hedge Mustard. 



" Pod rounded or 6-angular ; valves convex or 8-angled 3-nerved 

 (rarely with the lateral nerves inconspicuous or wanting). Hypo- 

 gynous glands none between the longer filaments. Seeds smooth, 

 their stalks slender. Stigma entire. Calyx spreading, equal at 

 the base."— Sr. Fl. 



1. S. officinale, Scop. Common Hedge Mustard. " Pods subu- 

 late pubescent close-pressed to the main stalk, leaves rimcinate 

 hairy, stem hispid." — Br. Fl. p. 34. Erysimum, L. : E. B. t. 735. 



In waste places, by waysides and along hedges, very^common. Fl. June, July.
