Polypogon monspeliensis (L.) Desf. Annual Beardgrass.
Foulness Island, 09.
The last Essex record for this grass was by C. Parsons of North
Shoebury Hall, c. 1839, who had many records from Foulness
Island. His sheet is not marked but it is quite possible that it
came from the same area.
Vulpia membranacea (L.) Dum. Dune Fescue.
St. Osyth Beach, 11; railway sidings, Parkeston, 23.
V. myuros (L.) C. C. Gmel. Rat's-tail Fescue.
Abundant at North Weald Station, 40; Cutlers Green, 52,
53. S.T.J., J.-W.
Sasa senanensis Bamboo.
Determined by J. E. Lousley. I put in this record as it
was seen in flower last year in several places, the two confirmed
records being Warley Place, 59, and Mount Quarter, Gaynes
Park, 40. This is unusual as Dr Hubbard tells us in his Pelican
Book on Grasses that different species have a definite life
cycle; they only flower and produce seed at periods ranging
from 15 to 120 years, then the whole plant dies.
Hypericaceae
Hypericum androsaemum L. Tutsan.
