on banks of rivers; pretty common in Scotland, less frequent in Eng- ‘3 
land; root is creeping; plant grows a yard high or more, 7 : 
‘acta grassy and flat, rough, cutting on the edges” and keel. Pani- - 
_ cle consists of innumerable little dark green, ovate spikes ; gluines ‘ 
obtuse with more or less of a small point: stigma 3-fid; seed len-— 
ticular, whitish, smooth with six or eight rough bristles. We have 
many Scirpi which are unknown in Europe. Sir J. E. Smith only 
names three which are unknown here, viz. S. setaceus, holoschemus 
and sylvaticus. 
Mr. T. also exhibited a specimen of the Andromeda mariana from 
the same locality; also the rarest of our American plants, Lygodium 
palmatum. A curious variety of Linaria vulgaris (the Pelorta of 
Lin.) was exhibited ; the corolla appears in the form of a cone, teI- 
minated above by a prominent border of five divisions, and below 
producing five spurs instead of one; so that according to Nuttall we 
have the ringent flower restored to its natural symmetry and regularity, 
this being the original condition of the flower, an opinion, however 
which is not substantiated.
