BOTANICAL REPORT 1880. II5 



Brassica Cheiranthus Vill.\ A few perennial plants with 

 well established roots, occurred on a grassy embankment by 

 the bridge over the railway a short distance west of Wetherby 

 workhouse, in company with Lotus tenuis Kit. An alien, and 

 a somewhat surprising one, since the species is a plant of 

 maritime sands. It must have been introduced, perhaps 

 with ballast (or Sarnian grass seed?); but precisely how, I 

 have no evidence. F. A. Lees. M.W. York. 



Hesperis matronalis Z.f Casual. On the sandy islet in the 

 Wharfe just below Boston Spa bridge. J. Emmet ! 



M.W. York. 

 Drosera obovata Bab. 



Leckby Carr, near Topcliffe. W. Whitwell. N.W. York. 



Silene puberula Jord. This scabrid-leaved variety of the 

 Common Catchfly is almost as common as the type on the 

 limestone about Wetherby. J. Jackson. M.W. York. 



Stellaria aquatica Scop. Damp hedge-bank in lane leading 

 from Ox-close House to Cowthorpe. F. A. L. M.W. York. 

 There is so great a resemblance in facies between this 

 species and S. nemonim, that all the Yorkshire records are 

 not to be trusted. The lowest leaves in both are stalked, the 

 stem of both is more or less pubescent-glandulous above, the 

 petals in both are cleft and longer than the sepals, and the 

 capsule in seed exceeds the calyx. Perhaps the readiest 

 method of distinguishing the two in the field is the compara- 

 tive difference in the length and stoutness of the flower 

 peduncles. In S. aquatica they are stout, viscous with glands, 

 straight for ^ths of their length and then rather abruptly 

 curved just under the capsule: in S. nemorum they are slender, 

 almost capillary and either straight or gently curving from 

 their slenderness through their whole length. In flower 

 S. aquatica has five styles : 6". nemorinn only three : in fruit 

 the capsule of the Water Stitchwort opens by five valves and 

 the diffuse much-branched dichotomous cyme is very brittle, 

 easily disarticulating at the nodes.
