Armerict plantaginea , Willd. Covering the sands in the 
western and southern parts of Jersey; exhibiting great 
variety in the breadth and vernation of the leaves. 
Atriplex arenaria, Woods. Plentiful St. Brelade’s Bay, 
J ersey. 
Orchis laxijlora, Lam. Marshy meadows to the south of 
St. Owen’s Pond, Jersey, with Spiranthes autumnalis. 
Allium sphcerocephalum, L. A few plants met with 
amongst old timber in St. Aubyn’s Bay. 
Scilla autumnalis, L. Very luxuriant at Noirmont 
Point, and Point La Frette, J ersey. The absence of bracts 
is often relied upon as a specific character, but I noticed 
many examples in Sark bearing these appendages. 
Alisma ranunculoides, L. var j3, repens, Sm. L’Ancrene 
Common, Guernsey, and St. Brelade’s, Jersey. 
Ruppia maritima, L. In salt-pans near the Yale 
Church, Guernsey. 
Oyperus longus, L. More plentiful in Guernsey than in 
the other islands. The farmers leave patches of this plant 
unmown in their meadows, in order that it may be gathered 
in the autumn for making into cordage ; the fishermen con- 
sider that ropes made from this plant wear much better 
in the sea than ordinary ropes. 
Cladium Mariscus, B, Br. St. Owen’s Pond, Jersey, 
growing with Scirpus Tabernoemontani and Scirpus pungens. 
It is remarkable that so conspicuous a plant has not hitherto 
been recorded as occurring in the islands. 
Polypogon monspeliensis, Desf. Road-sides, St. Samp- 
son’s, Guernsey. 
Lagurus ovatus, L. In the greatest profusion on the 
shores of L’Ancrene Bay, and Grande Havre, Guernsey.
