According to Hennedy's Flora, Cochlearia anglica, 

 Linn., is frequent about Bowling, Dumbarton, &c. I 

 am doubtful whether this species really occurs any- 

 where in the Clyde district. There is a large form of 

 Cochlearia officinalis found in the localities cited by 

 Hennedy; but I have failed to find any specimens 

 that agree with anglica as figured and described, or 

 with plants I have received from English stations. 

 This is the only Crucifer given as indigenous 

 by Hennedy, and occurring within the limits of 

 Hopkirk's district, not recorded in the Flora Glottiana. 



His variety groenlandica, of Cochlearia officinalis, 

 is most probably danica. Thlaspi arvense was then 

 very rare hereabouts, and it still is so. Its plenti- 

 fulness in some parts of the East country contrasts 

 very markedly with its almost entire absence from 

 our Western cornfields. Both Lepidiuin campestre 

 and L. Smithii are recognised by him under the 

 names Thlaspi cainpestre and Thlaspi hirsutum. 



Cardamine hnpatiens is still found "on rocks on 

 the banks of the river above the Falls of Clyde." 

 Though very rare in the district, it seems to be a 

 native. 



In a note to Cardamine pi^atensis, he says : " The 

 leaves fall off and take root in the earth, by which 

 singular mode it very frequently propagates itself." 



SisynibriuDi ainphihiuvi (now usually known by 

 the generic name of Nasturtium or Armoracia) he 

 states to occur occasionally, and gives several stations. 

 Hooker describes this plant in his Flora Scotica, 

 quoting the same stations for the GlasgoAV district. 

 The localities mentioned are : " Banks of the Clyde, 

 frequent. In the marsh beyond Fossil. In Bardowie 

 Loch, near the house." Fatrick also records this 

 plant; but Fossil Marsh is dropped from the list of 

 stations, and he says nothing about its being frequent. 

 He states: "Banks of the Clyde at Bogs. Bardowie 

 Loch, near the house." Hennedy says : " I have 

 never been enabled to find this plant in any of tliese 

 stations, nor in the district." It does not now
