doubt that every possible intermediate could be found connecting

Lamium maculatum L. var. l^vigatum L. Eoadside, Leigh 

 Woods, Bristol, N. Somerset, v.-c. 6, April 15, 1911. The type is 

 rather frequent about Bristol, but this variety is decidedly rare. — 

 Ida M. Eopee. This may very possibly be a native ; I have never 

 heard of the unspotted plant being cultivated in Britain. It was 

 the only one which I observed near Marburg, Hesse, in 1880. 

 Eouy divides L. maculatum L. into three "races " (Fl. de France, 

 xi. 298) : L. rugosum Ait. (L. maculatum auct. mult., Smith, English 

 Botany) ; L. hirsutum Lam. ; and L. rubrum Wallr. (L. Icevigatum 

 All., L. pro parte), which is apparently Miss Eoper's plant : — 

 " Feuilles irregulierement incisees-dentees, ovales-cordees, a lon- 

 gueur egalant envers leur largeur a la base, acuminees; verticilles 

 6-10-flores ; plante de 2-4 dec, a feuilles assez petites, ordinaire- 

 ment maculees de blanc ou de noir, rarement vertes." I grow the 

 plant commonly called L. maculatum, and its leaves are always 

 blotched with white. Koch (Synopsis, ed. ii. 649) says that 

 L. Icevigatum L. (Sp. Plant. 808), according to Bentham — who 

 examined the Linnean Herbarium for this [L. Icevigatum Eeichb.] 

 and L. maculatum — does not differ [from the type] ; but so many 

 of the Linnean specimens are badly dried and scrappy that I do 

 not believe that his opinion carries much weight. The aggregate 

 species is common in France, especially westwards, and occurs 

 in Spain, Portugal, Belgium, Holland, &c. ; so there is no prima 

 facie reason why it should not be indigenous in England. —

Polygonum , var. vel hybr. nov. ad Angl. Trodden cindery 



ground, Poole, Dorset, v.-c. 9, Oct. 5 and 9, 1911. Dr. Moss, who 

 was with me when we found this little novelty, will shortly de- 

 scribe it. Having the small fruit of P. microspermum Jordan, it 

 seemed to me at first allied to that plant. By the leaves and 

 habit it is nearer P. arenastrum, with which it was associated. — 

 E. F. Linton. A small form of Boreau's plant. — A. B. I think 

 that this pretty little plant is rightly placed as a variety, or form, 

 of P. arenastrum. I have two gatherings tending towards it, in 

 their small fruit and foliage, though they are more luxuriant and 

 less extreme, found near Hothfield, E. Kent, in September, 1891, 

 and on the sandy coast near Dunster, S. Somerset (with P. Baii 

 Bab.), in September, 1906.— E. S. M. The relationship of this 

 plant to P. calcatum Lindman, Bot. Notiser, 139 (1904), has to be 

 considered. Last September I found this species (new to the 

 British Isles) on Arthur's Seat, near Edinburgh. It has a fruit which 

 is sub-bifacial and not trigonous, and which has convex and not 

 concave faces. Professor Lindman, after seeing my specimens, 

 writes : " Your plant is indeed P. calcatum." — C. E. M. 



Poa nemoralis L., var. Perranarworthal, W. Cornwall, v.-c. 1, 

 June 6, 1911. — F. H. Davey. Eather weak type, I believe. — 

 E. S. M. This does not seem to agree with any British variety in 

 our books. — A. B. P. nemoralis L., var. vulgaris Gaud., forma
