the type in any particular save habit. --J as. W. White. Very 
luxuriant. I have found a plant with an inflorescence about as 
branched among the Kew specimens. According to Hackel this 
grass has cleistogamous flowers {Botanische Zeitsclirift, 1902, p. 474). 
Dr. Stapf points out to me that this species should be merged into 
Danthonia^ the structure of the glumes being essentially the same 
as in that genus. This is evident on comparing it with the 
European D. provincialise which differs in having awned pales, 
but this does not constitute a generic distinction. The American 
and Australian species of Triodia are totally different. I therefore 
suggest that the name Danthonia decumbens, DC., ‘ FI. France,’ 
III. 34 (1805), be revived. — A. B. Jackson. 
Sesleria ccenclea, Ard., var. luteo-alba, Opiz. I do not know 
that this beautiful grass has been noticed near Grassington before. 
It was fairly abundant in tufts on a steep slope with a northern 
aspect, 750 ft. above sea-level, this last June. Sesleria ccerulea, 
Ard., is always very abundant over a large area, and at different 
altitudes. — John Cryer. 
Koeleria crisiafa, Pers., var. . Groby Pool, 7th August 
1907. This form is far more robust than our general Leicestershire 
forms ; is it one of the forms which have recently been differen- 
tiated ? — W. Bell. This is, I consider, the K. cristata, of British 
authors, now called K. gracilis , Pers., subsp. britannica, Domin.— - 
E. S. M. K. gracilis, Pers. — E. Hackel. 
Koeleria, sp. Smallmouth Sands, Weymouth, v.-c. 9, i6th 
June 1907. — H. J. Riddelsdell. I cannot venture an opinion. 
It may be K. glauca, DC., var. albescens (DC.). I don’t think 
it britannica. — E. S. M. K. gracilis, Pers. — E. Hackel. 
K. albescens, DC. Plentiful on the Quenvais, Jersey, where 
I first discovered it in 1877. June 1907. — G. Claridge Druce. 
K. sciatica, DC., var. albescens (DC.), of the ‘ Lon. Cat.’ Ed. X. — 
H. j. R. 
K. I albescens, DC. Smallmouth Sands, Weymouth, v.-c. 9. 
i8tli and 20th June 1907. — H. J. Riddelsdell. K. albescens, DC. 
— E. Hackel. K. glauca, DC., var. albescens (DC.), of the ‘ Lon. 
Cat.’ Ed. X.— H. J. R. 
Poa Imlbosa, L., f. vivipara. Shore near Barry, v.-c. 41, i8th 
May 1907. Earlier and better specimens of the plant distributed 
last year. — H. J. Riddelsdell. 
P. nemoralis, L., variety. Plant green, erect, wiry ; frnit- 
panicle spreading. Exposed mountain rocks. Black Mountain ; 
Brecon and Hereford ; September 1907. This form is abundant on
