 in front of it, plentifully.

 spreading in fruit ascending and patent, spikelets linear of about 

 four flowers, florets free, outer glume of the corolla obsoletely 

 5-nerved with a minute point, root fibrous. Poa, Br. Fl. p. 536.

In muddy salt-marshes about the edges of drains and ditches. FL July — Oc- 

 tober. 1(. ? 



E. Med. — On the ooze of the ditch on the Dover, at the end of Mocklon street, 

 just by Harris yard, sparingly. On marsh-meadows behind the Dover, with P. 

 distans and P. procumbens, but not observed plentifully, 1844. [On the sea-wall 

 between Salterns and Sea View, constantly, Dr. Bell-Salter, Edrs.] 



W. Med. — Newtown marshes. Abundant in the first meadow, or that nearest 

 the sea, at Freshwater gate. Freshwater, W. Borrer, Esq. (Bab. in E. B.) 



Mr. Babington's description of this grass is so excellent and complete that I 

 gladly avail myself of his remarks, observing at the same time that in so doing I 

 do not adopt the species implicitly as distinct from P. distans or even P. mari- 

 tima, but rather confess myself sceptical on the subject, seeing how strongly it 

 partakes of the characters of both those grasses, and, as Mr. Borrer observes, of 

 P. procumbens also. 



Root fibrous or occasionally very slightly creeping. Culms 1 or several, nearly 

 erect, ascending or spreading, often so near the ground as to appear prostrate, 

 from 6 to 18 inches or more in length, straight, rigid, round or slightly com- 

 pressed, smooth and shining, in drier situations often with a tinge of purple, ge- 

 niculate at one or two of the lower joints, naked for a considerable distance 

 beneath the panicle. Leaves linear, flat, roughish above and along the margins ; 

 those on the upper portion of the stem few, short, distant, on very long, loose and 

 furrowed sheaths. Ligide fhort, broad and truncate, slightly torn or sometimes 

 bifid. Panicle of se\ era! distant, alternate, half-whorled sets of slightly compound 

 branches, that are at first erect, afterwards patent or spreading at various angles, 

 rigid, angular and scabrous, with a yellow glandular tumidity in the axil of each 

 branch on its upper side. Spikelets small, ovate or ovato-lanceolate rather than 

 linear (nor are they so drawn in the ' Supplement to English Botany,' the figure 

 in which, though small, is excellent), 3 — 6 flowered, usually more or less tinged 

 with purple, falling away from the calyx when beginning to dry or soon after 

 gathering. Calyx much shorter than the florets, its glumes veij unequal, smooth, 

 membranaceous and concave ; exterior and smaller one with a single strongly 

 marked central rib, often scarcely extending to the acute apex ; interior and 

 larger glume 3-ribbed, the middle rib reaching to the obtuse summit, the two 

 lateral terminating about ^rd below it. Palece smooth. 



Named by Mr. Babington after its discoverer and our mutual friend, Wm. 

 Borrer, Esq., one of the most acute botanists of the present day.
