250 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES, 
the panicle ; the panicle thin, few flowered, colourless. Glumes 
very unequally-flowered. Lower palea acuminate, obtuse, 5-ribbed. 
In this plant the leaves are about as long as the panicle, and in such 
florets as I have examined I find that although i -flowered the glumes 
are coloured with violet, and the lower palea has three nerves, a 
character which Lindley gives for M. cctrulea. — G. Claridge 
Druce. 
M. cxrulea^ Moench. ( = varia^ Schrank.) var. robusta, Prahl. 
(‘Krit. FI. Schleswig-Holstein,’ II. 257, 1890,) ‘ B. E. C.’ Report, 
1904, p. 38. Two years ago I was unable to forward more than two 
or three examples to the Club of this very interesting grass, lately 
pronounced to be Prahl’s plant by Prof. Hackel. It forms large, 
spongy, somewhat solitary tussocks in one place only, towards the 
S.W. margin of Bomere Pool, Salop ; in a lordship unfortunately 
quite lately devastated by fire, which has killed many plants ; 
Lastrea spinulosa, Presl., occurs with it.” — J. CosMO Melvill. “ I 
have known this plant for many years in south-west Surrey, where 
it occurs plentifully in boggy alder-beds, &c., on peaty soil ; but I 
doubt its deserving to rank as a good variety.”— E. S. Marshall. 
Poa annua, L., var. supina, Gaud. Mountain borders of Brecon 
and Caermarthen, July 1906. N. C. R, — A, Ley. “No ; Gaudin’s 
variety has the spikelets beautifully tinged with violet-purple. This 
only tends somewhat towards it”. — E, S. Marshall. 
P. bulbosa, L., forma vivipara. Near Barry, Glamorgan, v.-c. 
41, 26th June 1906. First discovery in Wales ; hitherto known 
from South Devon, Wight, Sussex E, and W., Kent PI., Suffolk E., 
Norfolk E. : this is therefore a considerable extension of range. 
The locality is a pebbly shore, with mud among the pebbles. In 
considerable quantity and in company with large quantities of 
Trifolium striatum, &c. — H. J. Riddelsdell. 
P.glauca, Sm. Origin Carnedd Dafydd, Cam. Cult., 23rd 
June 1906. — A. Ley. “This appears to be a different plant from 
the specimen sent by Rev. A. Ley through the Club in 1890, The 
older name is P. caesia, Sm.” — G. C. Druce. 
P. nemoralis, L., var. . Ref. Nd. 2995. Linn of Corrie- 
mulzie, Braemar, v.-c. 92, S. Aberdeen, 20th July 1906, This was 
gathered by Mr. J. F, Hanbury and myself in 1886 ; and was then 
referred to var. Parnellii, Hook and Arn. I think, however, that it 
is more probably weak, shade-grown var. divaricata, Syme, which is 
the prevalent form of rocky stream-sides in the district. Foliage 
rather glaucous. — Edward S. Marshall. “ 1 think this is var, 
stihuniflora, Reichb. Professor Hackel named a plant which I 
gathered in this locality, 1882, P. Parnellii, Bab., but subsequently
