NOTES RESPECTING SOME PLYMOUTH PLANTS. 267 



sharply pointed, the peduncles longer, and the calyx tube narrower. 

 The petals are sometimes of a bright pink, but generally of a lighter 

 tint, which is occasionally mottled with a deeper colour ; very rarely 

 they are quite white. Sometimes the styles are so united as to form 

 a prominent column, whilst at others they are much shorter and only 

 partially agglutinated. I would put it with the Canince rather than 

 the Systylce group. 



Valerianella Auricula^ DC. I believe the comital census of this 

 would soon be raised if botanists would carefully look out for it inter- 

 mixed with V. dentata. It is not rare about Plymouth, though con- 

 siderably less abundant than the other, with which it is almost in- 

 variably associated, whether growing in fields, on banks, or, as is oc- 

 casionally the case, in dry spots by roadsides. 



Crepis taraxacifolia, Thuil, Spreading over great part of the 

 country at a very rapid rate, threatening to become quite a common 

 and noxious weed. It has this season again and again presented itself 

 to notice in unexpected spots to which it has recently spread. 



Crepis biennis, L. This still grows in considerable quantity on a 

 railway bank between Bickleigh Station and Shaugh Bridge, where I 

 first noticed it in 1868, and whence I have sent specimens to the Bot. 

 Ex, Club. Unlike the taraxacifolia, it is not extending over the 

 country, though maintaining its ground in plenty at the one spot. 

 When we look at the two plants together it seems remarkable that 

 they should have been so much confused, the flowers of biennis being so 

 much larger and handsomer than those of the_, other, which, except in 

 its rough foliage and the shape of its root-leaves, is really more like 

 that large form of C. vire?is, we often see among our sown grasses and 

 clovers. I believe both taraxacifolia and biennis to be recent intro- 

 ductions here. 



Linaria vulgaris, Mill. The curious form or variety Peloria grows 

 on a hedge bank at Hay, between Torpoint and Anthony, East Corn- 

 wall. 



Sclerochloa Borreri, Bab. On a damp slaty bank above a brackish 

 stream at Crabtree, growing sparingly with S. distans, June, 1875. 



Poa compressa, L. I am able to give a second Cornish station 

 {vide Joum. Bot., vol. ix,, p. 306) for this inconspicuous grass, from 

 having recently found a patch of it close to Heskyn Hill, near Tide- 

 ford. 



Nephrodium spinulosum, Desv. In plenty in a swamp in a large 

 wood by a tributary of the Seaton, between Treloy Earm and the 

 Hessenford and Seaton Eoad, East Cornwall, growing about immense 

 tussocks of Car ex paniculata, 1 875. But few Cornish stations for this 

 Fern are on record. 



All the places named above are in South Devon unless the contrary 

 is stated.
