sheath of the spike black, spreading, campanulate, its teeth 
long, acuminate, aristate. 
Teeth rigid, harsh, rounded or truncate at the apex, each having a 
median furrow on the back, the continuation of the intermedi- 
ate furrows of the sheath ; surmounted by loose, flaccid, mem- 
branous, silky, elongate, pointed awns, which are usually whitish, 
but occasionally black towards the apex of the stem; on the 
lower sheaths these awns appear evanescent, from their extreme 
fragility. 
Spike sessile, black, composed of 35 (more or less) black, roundish 
scales, on which the striation of the stem is indistinctly conti-

seen it form the entire covering of a wall most luxuriantly ; and dug 
up a single root, from the bank at the foot of it, on which I counted

Staffordshire Locality for Potamogeton flabellatus, Bab. 
“To the localities already recorded for this pond-weed, may be 
added the river, and ditches which drain into it, at Stafford. The 
plant has been known to me, as a doubtful form, for several years. 
Although most abundant and luxuriant in growth, it flowers very spar-
