4. Position in Hackel’s scheme of the three forms 
under investigation. 
The first form 1 have investigated, which is dark-green in colour, 
and which occurred as a weed in Professor Trow’s garden, agrees 
with (3. grandiflora and compares well with herbarium specimens 
of this in the British Museum. The second form is yellow-green 
and was found near Chepstow. While possessing the large spikelets 
of grandiflora it agrees fairly closely in other respects with 
y. glaticescens. Herbarium specimens so named at South Ken¬ 
sington are rathermore glaucous and have smooth rachides. The 
third form is glaucous-green and came from the Barry pebble-ridge. 
It undoubtedly falls under var. genuina, but does not correspond 
with any of the sub-varieties described. One specimen only at the 
South Kensington Museum appears to agree with it (No. 1570, 
Festuca 504 s Sp. 6 rubra). This was collected by Augustin Ley, 
June 25th, 1879, from “banks just above tidal mud under Wynd 
Cliff, Mon., Alluvial.” The position and locality further suggest an 
agreement, but the specimen, if this is the case, is not a typical 
one, since it has a creeping habit. This might, however, be a fault 
easily committed by a collector unacquainted with the special habit 
of the plant. It is described as follows: “ Festuca repens=F. rubra 
sp. pl.=F. cambrica Huds.” “ A variety of duriuscula ” (Rev. Hugh 
Davies). “ Doubtless under this as a super sp. . . . Another form 
of F. rubra" (A. Bennett).
