EEPOETS. 121 



Salix Smithiana, WilU. (Silky-leaved Osier). This willow occurs low 

 down on the cliffs at Or eve de la Ville, and is a hybrid between S. caprea 

 and S. cinerea. 



Luzula multiflora, J acq. (Many headed Wood-rush). Little Sark, near 

 Vermandee ; a native. 



Carex arenaria, L. (Sand Sedge). A native. Very sparingly near Port 

 Gorey. Plentifully, but flowering \>ery sparingly at Les Petits Creux, on 

 western side of Little Sark. The occurrence of this sand-loving species 

 on the rocky Sark coast is curious. It is perhaps a relic of a time when 

 Sark possessed a sandy shore. 



Carex punctata, Gaud. (Dotted-fruited Sedge). Native. In fair plenty 

 along a rocky gully close to the bay Eouge Caneau in Little Sark. The 

 gulley descends exactly opposite a small pool of fresh water on the coast. 

 Very sparingly between Vermandee Bay and the Coupee. Very sparingly 

 on the cliff in the centre of Vermandee Bay. 



Carex flava, L. (Yellow Sedge). Growing in the gully near Eouge 

 Caneau mentioned above, I found a curious form of Flava, about which 

 the Eev. E S. Marshall writes me as follows: — "It must come under 

 aggregate 0. CEderi, Eeitz, and is perhaps nearest to var. (Edocarpa, And. 

 (G. flava, var. minor, Towns ), but I have nothing Cjuite like it; the pis- 

 tillate glumes are green (scarcely showing a trace of the usual reddish - 

 brown) and the fruit is extraordinarily patent. So I can only say : 

 G. CEderi, Eeitz, var. 



Aira CCespitosa, L., var. pallida, Kock (teste E. F. Linton). (Tufted Hair- 

 grass). An alien. Very sparingly in the grounds near the Seigneurie. 

 Probably introduced with the ornamental shrubs planted there. Not 

 recorded for Guernsey, which is curious, as it is common and native in 

 Normandy. 



Barbarea vulgaris, It. Br. (Yellow Eocket). Colonist. In a cultivated 

 field near the Seigneurie, also near Valette. Mr. Derrick had noted this 

 species previously in Sark, but had not recorded it. 



Two further additions to the Sark group, viz., Vic? a 

 septum, L., and Ophioglossum vulgatum, var. ambiguum, are 

 recorded in the Flora of Brechou. 



I may also mention Bromus madritensis, L., var. n'gidus, 

 Roth., is well scattered round the Sark coast, occurring plen- 

 tifully in some places. It also grows inland and at the Coupee. 



Vicia tetrasperma, rare in Guernsey, is rather frequent in 

 Sark hedge-banks, and seems quite a characteristic plant of the 

 island. 



Mr. Hurst has made excursions to Brechou, or Isle des 

 Marchands, and catalogued the plants he found there ; it forms 

 quite an interesting list of 205 species (see page 163).
