(not Miss) Cookson, as having been once named Potamogeton grammeus by 

 me. 1 am sorry that lie has not received any intimation of my ultimate 

 views concerning- it : views fmnided chiefly upon tlie examination of speci- 

 mens most kindly sent by him. The plant in question has not the rhom- 

 boidal sepals of P. gramineus, but possesses the transversely oval ones of 

 P. conipressus. It has also the longer and rather clavate peduncles of the 

 latter plant. The difficulty concerning its name arose from its leaves 

 generally not having more than one vein upon eacli side of the midrib. 

 But a careful examination of the copious supply of specimens sent by Mr. 

 Green, has shown that some of the leaves have the five veins (two on each 

 side of the midrib) usually found in those of P. comprenms. The veins are 

 aU, except the midrib, very faintly marked in these specimens. The plant 

 is therefore the P. conipressus of Smith, and almost certainly of Linnaeus. 

 Closely as P. compressus is allied in technical charactei's to P.pusillus, spe- 

 cimens of it are far more likely to be mistaken for P. gramineus.

"Botanizing in the Channel Islands." 



A short paper with this title appeared in the ' Phytologist ' of October 

 last year. The list of plants found contained two or three species on which 

 I wish to make some remarks and corrections. 



Delphinium Consolida : the Larkspur met with was the Delphinium ^Jacis, 

 and the D. Consolida of English authors, but not the true D. Consolida. 

 Papaver somniferum : perhaps not so, but a nearly allied species ; further 

 observation is required. (Enothera biennis .• the (Enothera referred to I 

 found near the windmill in St. Aubin's Bay, and although certainly not 

 the ordinary form I referred it as a variety to (E. biennis ; Mr. Baker, 

 however, suggests that it may be the (Enothera suaveolens, Desf. Juncus 

 compressus: not compressus, but one of two very distinct forms of/, ccenosus, 

 which grow together in the Vale, Gruernsey. Herniarin ciliata, Chenopodium 

 vmrale, and Festuca vniglumis, and the true Viola canhia {Viola flavicornis, 

 Sm.), may be added to the list. Alfred M. Norman.

Camelina sativa. 



On the 10th July, 1860, I foimd Camelina sativa growing in tolerable 

 abundance in a field of barley, on Pursdon Estate, in the parish of Egg 

 Buckland, a few miles from Plymouth, and 1 enclose a specimen then and 

 there obtained. As this plant is not named in the recently published ' Flora 

 of Devon,' perhaps you may consider this communication worth insertion 

 in a future number of the ' Phytologist.' I can add the following Devonian 

 localities to those given by the Eev. T. F. Eavenshaw : — Silene anglica: 

 field near Maristowe House. Lotus corniculatus, var. tenuifolius : hedge- 

 bank between Plymouth and Yealmpton. Lathyrus Aphaca .• amongst 

 Furze by the roadside between the villages of Knackersknowle and Ta- 

 merton Foliot. Pyrus torminalis : Fancy Wood. Carduus acanthoides : 

 pasture near Yealmpton. Centunculus minimus : Koborough Down. Gym- 

 nadenia Conopsea : Koborough Down. T. E. A. Briggs.
