50 CRUCIFERAE 



5. Loddon. Sonning railway cutting, Tufnail. Bracknell, Ascot. 

 Bagsliot. Loddon Bridge. Wokingham. Finchampstead. 

 Virginia Water and Windsor Great Park. Binfield. High 

 Standing Hill. Cranbourn Park. Warren Eow. 



This plant is much commoner in the Loddon district on the Bag- 

 shot Sands than on the other formations, but it is generally distributed 

 in suitable localities. 



Var. UMBROSA (Gren. & Godr. Fl. Fr. i. no as a var. of C. sylvatica , 

 is a large shade-grown branching form with the leaves much angled 

 or cut, which when out of flower bears a good deal of superficial-" 

 resemblance to the shade-form (var. umbrosa) of C. amara, with which 

 it grew in Aldermaston Soak. Some flowerless specimens of the latter 

 form were accidentally distributed for the former bj'' the author 

 through the Bot.Exch. Club in 1888. I have also seen it at Tilehurst, 

 Padworth, &c. 



C. flexuosa, which is placed as .synonymous with C. hirsuia in Index 

 Kewensis, occurs in all the bordering counties. 



[C. iMPATiENS, Linn. Sp. PL 655 (1753). Syme, E. B. i. 161, t. 112. 



Error. This plant is included in Mr. Pamplin's list of Streatley plants, 

 which appeared in the Phyt. v. (1854) 154? but he probably mistook C. flexuosa 

 for it, since he mentions neither C. liii^suta nor flexuosa. 



The true C. impatiens occurs in Surrey only of the counties bordering upon 

 Berks.]
