4tli. To H. vernicosum of Lindb., by Wils. MS. ; auct.

5th. To H. Kneiffii, small form, which Dr. Schimper has 

 recently shown to be the plant to which Hedwig originally 

 gave the name of H. aduncum. 



Limnobium engyrium, Schr. Next L.palustre, but distin- 

 guished by the very large fulvous alar cells of the leaves, 

 and the shorter, wide, annulated capsule. Colour, a fine 

 brown or red. Bocky streams : North Wales, Devonshire, 

 Killarney. This, according to D. Schimper, maybe distinct 

 from the continental plant, and, as such, is named by him

 forms, but not more so than those from North America,

 a much smaller, less robust plant ; stems slightly pinnate, 

 leaves less strongly nerved aud striated. Prostrate in deep

 uncum, Hook . and Tayl. olim) . Stems irregularly branched, 

 capsule short, cernuous, leaves like those oiH. commutatum.

 but distinguished by the large pellucid alar cells of the 

 leaves and small phyllidia. Beigate Heath, Surrey, June 

 1864, female plant only, Mr. Mitten. See Seeman^s 

 Journal of Botany, July 1864.
