ERAGROSTIS POJSOIDES. Fal. de Beauv. 
In a new made road at Birkenhead, Chester, Mr. F. M. Webb. 
POA DISSITIFLORA. Bdm. ^ SchuUes. 
The Rev. W. W. Newbould identifies a Poa from Ben Lawers 
contained in Smith's Herbarium with P. dissitiflora, Horn. ^' Schultes, 
on the authority of authentic specimens from Greenland, collected by 
Hornemann, contained in the Kew Herbarium. From a misapprehen- 
sion on my part, I believed that Mr. Kewbould had identified the 
plant figured in English Botany by Smith as Poa glauca with P. dis- 
sitiflora, but in a subsequent letter Mr. Newbould explains that this is 
not the fact, so that the name " dissitiflora " on PI. MDCCLXVI. 
will be found in the Errata to this volume corrected into " eu-glauca." 
Being unable at present to visit the Kew Herbarium, I can offer no 
opinion on the subject, though, from what Mr. Newbould writes, 
P. dissitiflora must be either the plant I have called P. Balfourii, 3. 
amhigua^ or P. nemoralis, 8. glaucantha. Romer & Schultes' descrip- 
tion is insufficient to decide the point. 
POA SUDETICA. Bdnle. 
"Kew Grounds, Dr. Hooker, and Warwick, Mr. Kirk." Comp. 
" Cyb. Brit." p. 594. I have gathered it also in Battersea Fields in 
1853, on mud dredged from the Thames; and, in the same year, in 
the grounds of Chelsea Hospital. 
BROMUS TECTORTJM. Linn. 
In waste places near towns and on ballast ; but scarcely established, 
except at Gloucester Docks. Professor Thiselton-Dyer tells me he 
has met with it on St. Vincent's Rocks, Bristol. The secund panicle 
and horizontal spikelets at once distinguish it from B. Madritensis. 
BROMUS UNIOLOIDES. WiUd. 
Round a partly drained pond in Warwick Old Park, and in a 
potatoe-field at Woodcourt, Warwickshire, Mr. H. Bromwich ; also 
in a field at Newton in Cleveland, Yorkshire, 1854, Mr. W. Mudd. 
BROMUS PATULUS. MeH. S,- Koch 
In waste places near towns and on ballast; apparently established 
at Gloucester Docks. In 1853 it was plentiful on the mud taken 
from the Thames and laid on Battersea Fields. Prof. Thi>elton-Dyer
