44 CRUCiFEE.E. [Capsella- 



Lepidium sativum, L. (Common Cress) occurs occasionally in fields and along 

 hedges, but is scarcely naturalized, nor is its native country known I believe with 

 certainty, though stated to be indigenous to the Levant. 



XVIII. Capsella, De Cand. Shepherd's Purse. 



" Potich laterally compressed, ohcordato-cuneate (or elliptical) ; 

 the valves navicular, without wings ; cells many-seeded." — Br. Fl. 



1. C. Bursa- Pastoris, DC. Comnwn Shepherd's Purse. 

 " Pubescent or hairy, stem-leaves sessile lanceolato-sagittate, 

 pouch ohcordato-cuneate." — Br. Fl. p. 36. E. B. t. 1845. 



In waste and cultivated ground and in every soil and situation ; one of the com- 

 monest of weeds. /■;. March— November. 0. r . i 



The root when newly pulled up emits an odour like the smoke of pit-coal, 

 whence this plant might with more propriety have been called Fumitory {Fumus 

 terrce) than the herb to which the name has been from time immemorial assigned, 

 (Fumaria).* 



** Pouch evaluate indehiscent. 



XIX. CoEONOPUs, Haller. Wart-cress. 



" Fruit broader than long, 2-celled, without valves or wings ; 

 cells 1-seeded." Cotyledons long, linear, curved. — Br. Fl.

 nent." — E. B. t. 1660. Senebiera Coronopus, DC. : Br. Fl. 

 p. 38. 



In waste places, at the foot of walls and by waysides in and about towns, also 

 on dry short pasture, very common in most parts of the island. Fl. May — Sep- 

 tember. 0. 



Very abundant in the Spencer road, on the Dover, and generally about 



Ryde. 



t2. C.didyma,Sm. Lesser Wart-cress. " Fruit emarginate of 

 2 wrinkled lobes, style very short." Senebiera, Br. Fl. p. 38.

 duced. i^Z. July — October. 0. 



E. Med. — At E. Cowes in several places. First found at the N. end of the Rope- 

 walk there,f by Miss G. Kilderhee, and near the Medina Hotel !!! I have since 

 found it, though sparingly, in a dry ditch by the shore nearly opposite Miss 

 Sheddon's house at Statwood, as also on waste ground thereabouts. 



* There are other plants possessed of odours analogous to those of sub- 

 stances quite foreign to their composition, as Psoralea bituminosa, which exhales 

 a. strong smell of coal-tar. 



f The plant is now destroyed at this station by recent building.
