Diplotaxis teriuifolia, DC. Locally common on the north and north- 

 western coast. Abundant on Vazon Green.

 Lepidium latifolium, L. Rare ; plentiful where it occurs. Approach to 

 Cobo. Western end of Vazon Green. Les Goubais (IX.) 



L. FUderale, L. Very rare. Quarry heap near Vale Castle, and roadside 

 beyond, sparingly. 



L. sativum, L. Very rare. On the shore at the south side of Grand Havre. 



L. Smithii, Hook. Rather common. 



L. Draba, L. Rare. North side of Bordeaux Harbour. Hedge -bank beyond 



Les Videclins (VIII.) Coast north of Richmond Hill. Lane by Les 



Hunguets (II.) 



Thlaspi arvense, L. In cult, fields, rare. Noted in II., VI., VII., IX. 



andX. 



Teesdalia nudieaulis, R.Br. On the cliffs from Fermain to Petit Bot, 



frequent . Talbots Valley, a few specimens. 

 CPambe maritima, L. Very rare. Portinfer, in fair quantity. Lihou 



Island, one plant. 



Cakile maritima, Scop. All along the coast from Rocquaine to Belgrave 

 Bay, but not very common. 



Raphanus Raphanistrum, L. Frequent in VIIL, IX. and X. 

 R. maritimus, 8m. Common all round the coast.

V. arvensis, Murr. Common in cult, fields. 



V. nana, DC. Rare. On the sandhills near the Great Cromlech, L'Ancresse. 



All round Rousse Martello Tower. 

 Polygala vulgaris, L. This species with the next, taken as an aggregate, 



is quite common. Fairly typical eu-vulgaris is occasionally to be met 



with, but the great bulk of the forms can scarcely be assigned with 



confidence to either. 

 P. OXyptera, Reich. Very common at Pleinmont. Petit Bot cliffs. 



Corbiere. L'Eree. Not quite typical, the capsule being usually shorter 



though broader than the wings. 

 Frankenia lseviS, L. Very rare. In two sandy fields at Grandes Rocques 



(the locality indicated to me by Mr. Derrick) . I believe I am correct in 



naming this plant, but I have not seen it in flower. It was found in the 



island, however, by Professor Babington. 

 Saponaria Officinalis, L. Overrunning a low hedge in the lane from Cobo 



to Ozanne's Tower ; probably an old garden escape.
