Lees ; sporadic. With this I also gathered Beta 

 inaritinia, Eschscholtzia californica, Gilla capitata (on 

 bank of R. Calder, Horbury, as well), and a species 

 of Composit(z — name uncertain. On submitting them 

 to Mr. J. G. Baker, F.R.S., Kew, he said ' these 

 weeds are all Californian, introduced no doubt with 

 wheat.' 

 77. Nasturtium syivestre Br. Yellow Cress. Canal-banks, 

 Thornhill Lees. 



84. Barbarea praecox Br. American Cress. Rail-bank 

 by Thornhill Junction Station. A garden escape 

 (F. A. Lees). 



149. Teesdalia nudicaulis Br. Near Mirfield ; H. Baines 

 .... ' Sought here in vain, 1870.' Probably extinct 

 there now. Vide 'The Flora of West Yorks.,' p. 148. 



179. Polygala depressa Wend, (sub-sp.). All the Milk- 

 wort in this district has hitherto been put down as 

 P. vulgaris. During a walk Ave had together here, 

 in search of more Rubiis podophyllus in August, 1887, 

 my attention was drawn to the matter by Mr. F. K. 

 Lees, the Recorder for the Botanical Record Club, 

 and on the examination of a series of local gatherings, 

 it was found that our form must be changed to P. 

 depressa., the one usually occurring on heaths. It 

 only grows on dry meadow banks in the higher parts 

 of this district, and in all specimens examined, the 

 plants have the flexuous stems, spathulate lower leaves 

 and short bracts, characteristic oi depressa. The type, 

 P. vulgaris, with ascending stems, straight branches, 

 narrow leaves and longer bracts, seems to occur farther 

 down the Calder Valley, about Wakefield. In 1888 

 I gathered true P. vulgaris, with white flowers, at 

 Birkenshaw, therefore No. 177 will remain in my Flora 

 with the changed locality.
