to the var. f/labra. Its hybrid origin is already shown by the uni- 

 versally abortive fruit. — A. H. Wolley-Dod. " I quite agree in 

 this naming. The tendency to reflexed sepals in some of the fruits 

 points to R. canina rather than /t. (jlauca as the second parent. 

 The glabrous leaves, with here and there compound serrations, and 

 a few glands on the petiole, suggest li. damalis as the canina form." 

 E. F. Linton. 



R. DUMETORUM Thuill. Glcbc hedges, Knighton, Radnor, 8th 

 August, 1899. M. Crepin writes of this : "I do not think that this 

 form belongs to the coriifoUa group, although its sepals are ascending. 

 Its styles are not woolly as in E. corii/olia, and, besides, its general 

 facies is not that of the latter. Perhaps one should see in this form 

 a variety of U. canina of a group near B. dumetorim, with teeth often 

 a little glandular. R. implexa has the leaflets glabrous, excepting 

 the midrib." I had suggested the alternative names, R. coriifoUa 

 Fr. or R. implexa Gren., to M. Crepin, on account of the (usually) 

 strongly ascending sepals, but his comment on this character in 

 many examples is often " sepales redresses accidentellement," so 

 it appears that that character is not to be relied on. — A. H.

Myosotis versicolor Reichb. ? var. pallida Brebisson. This 

 variety is common on dry banks in Jersey, April and May, 1899, 

 and is very consistent in colour, though variable in habit. The 

 points of distinction are — {a) foliage a yellower green ; [b) calyx 

 never tinged with purple ; [c) flowers pure white, never yellow, 

 never shading off into, or turning, blue. It appears to differ from 

 M. Balhisiana Jord., the flowers of which are yellow, and from 

 M, duhia Arrondeau, the flowers of which are white, but turn blue. 

 In Brebisson's Flore de Normcnidie two other varieties are given : 

 (1) var. pallida, flowers white or very slightly yellow; (2) var. 

 ehmyata, " stems weak, little branched, elongate. Flowers yellowish, 

 then reddish, very small." The Jersey plant seems to correspond 

 with var. pallida. In Joiirn. Bot. 1893, p. 266, a " white variety 

 with paler foHage " is mentioned as found in the Scilly Islands. — 

 L. V. Lester. " Is this variety of J\L versicolor more than an 

 albino form which would have, in addition to white flowers, foliage 

 of a paler hue ? " — E. F. Linton. 



PoA TRiviALis L. var. glabra Doll, Rhein. Fl., p. 92. In Bloxham 

 Grove, near Banbury, Oxfordshire, June, 1899. This plant is con- 

 tained in the British Museum Herbarium under the name of P.pra- 

 tensis, coll. A. French, 1878, but the specimens there suggested to 

 me, at a cursory view, a form of P. nemoralis, but the ligule did not 

 agree. French evidently saw that it was abnormal, and he remarks 

 that it was the prevailing grass in the Grove. This grove is a 

 circular spinney, planted probably in an old stonepit ; but the trees 

 have gone from the centre, and it is now open to cattle, who evi- 

 dently make it a resting-place, since the grass was so trampled down 

 as to render it impossible to obtain good specimens. Prof. Hackel 

 agrees with me in referring them to this variety of P. trivialis. — 

 G. Claridge Bruce.
