NOTES ON JERSEY PLANTS 17 



Ranunculus flabellatus Desf. Quite a respectable patch — not 

 yet in flower — found in a new station more than tw T o miles from 

 the St. Aubin's locality, where it was also observed, and additional 

 to those mentioned in Journ. Bot. 1910, 188. 



Barbarea intermedia Bor. Eoadsides south-east of St. Ouen's 

 Pond and north-west of Becquet Servais. 



Cerastium tetrandrum Curt. var. nov. dunense. On the Quenvais 

 sandhills (and on the Vazon Bay shore, Guernsey) a remarkable 

 Cerastium attracted notice. It was robust, prostrate, very glan- 

 dular (often with grains of sand adhering), its leaves large and 

 fleshy, and the branching (and often purple colouring) reminding 

 one strongly of Euphorbia Peplis. 



I cannot find any recorded descriptions that may apply to this 

 sand-form, and after comparing a series of specimens with ex- 

 amples of the type, further distinguishing characters came to 

 light ; hence I venture to suggest that it may be convenient 

 to name it var. dunense, with the following diagnosis : — Planta 

 prostrata, glandulosissima, rami et folia crasso-carnosi, calyx et 

 capsula grandiores et latiores quam in typo, capsula tertia parte 

 usque ad dimidium sepalis longior et perspicue curvata. 



Specimens in Herb. Mus. Brit, labelled " S. Aubin's Bay, 

 Jersey, 24 April, 1871, H. Trimen " are apparently identical with 

 the above, but the collector's decision (Journ. Bot. 1871, 199) that 

 they should be placed under C. pumilum Curt, is not a sound one, 

 I think, nor will they match the G. pedunculatum Bab. or C. atro- 

 virens Bab. (Mag. Zool. & Bot. ii. 200, 317, 1838). 



Examples distributed by F. Schultz, Herb. Norm. Cent. 7, 

 620, seem exactly the var. dunense ; these came, as one might 

 expect, from the nearest French coast to Jersey, in the Manche 

 Department. 



C. semidecandrum L. var. *congestum Gren. Abundant on the 

 sandhills, St. Aubin's Bay. 



This is described by Grenier as follows in Monog. Cerast. 

 184] , 29 : — " Pedunculis brevissimis, floribusque abbreviatis, con- 

 gesto-umbellatis, numerosis, densis, calicibus globosis, capsulaque 

 calicem vix excedente." 



This description seems to fit the Jersey plant, which was quite 

 noticeable by its crowded heads of flowers, remarkably short 

 peduncles and short capsules, well retaining these characters in a 

 large series gathered. It is quite glandular, and grains of sand 

 are usually to be found adhering to the upper parts. Rouy & 

 Foucaud (Fl. France, iii. 1896, 219) do not mention this name 

 congestum as a synonym for any of the six varieties given under 

 G. semidecandrum, and none of the descriptions of these seems to 

 suit the Jersey form. 



Sagina ciliata Fr. Portelet Bay. 



Spergula arvensis L. var. nana Linton. West Mount ; Por- 

 telet Bay. 



Montia chondrosperma Fenzl. Near First Tower. 



Trifolium suffocatum L. Portelet Bay. 



Anthyllis maritima Schw. Portelet Bay. Apparently quite
