PLANT NOTES FOR 1929. 21
by Major Bates Van de "\Veyer, in which the ripe fruits separate from
the receptacle, are dull red in colour, and have the flavour of Raspberry.
It is not a sub-erect species. The stems root at the tips, but
I can see no evidence 'in the leaf or stem of idaeus. G. C. DRUCE.
Mr W. "\VATSON says :-" The completely septenate leaf and the
felted drupelets point unmistakably to the presence of idaeus. R.
idaeus has felted carpels, but none of the blackberries have; I think the
other parent is ulmifolius not caesius. Vide the long panicle and strong
based prickles. This hybrid has not, I think, been reported previously,
either in this country or abroad. Usually R. idaeus is out of flower
when B. ulmifolius begins to flower."
185/47. R. ULM.IFOLIUS Scho;tt, var. CONi'RACTIFOLIUS (Sudre). So
named by W. WATSON. Hunsbury Hill, Northants, September 1929,
U. C. DRUCE; Bromley, Kent, "\V. WATSON.
185/ R. MACROSTACHYS P. J. M., t-este W. WATSON. Sussex, a,s
ERICETORUM. Not the real ericetortlrh LeHlVre (the bramble which
Rogers published as R. Radula, sub-sp. anglicanus), nor is it the
Bramble which Rogers issued as R. Lejeunii, var. ericetorum Lef. It
is, I think, pretty certainly R. macrostachys P. J. M., which Focke says
he received from Rogers as anglicanus. It agrees splendidly with
P. J. M.'s own description, and with Sudre's description. It is not,
of course, B. fuscus, var. macrostachys Rogers. VV. WATSON.
185/72. R. LASIOCLADOS, var. ANGUSTIFOLIUS x PYRAMIDALIS, teste
W. WATSON. A very beautiful plant growing with the parents near
Bagley Wood, Berks, G. C. DRUCE.
Var. ANGUSTIFOLIUS x VESTITUS, teste W. WATSON. Bagley Wood,
Berks, G. C. DRUCE.
185/73. R. EGREGIU8 Focke. Boars Hill, Berks, G. C. DRUCE. Det.

Salmon in Journ. Bot., 13, 1929.
190/7. A. TENUIS Buser. Boxwood, Herts, June 12, 1911, J. E.
LITTLE. This was probably a mixed gathering since Mr C. E. Salmon
says his specimen is not tenuis, but M. J aquet, having again examined
my specimen, agrees that it is tenuis.
190/8(2). A. ACUMINATIDENS Buser in Bull. Herb. Boiss., ser. 2, ii.,
624-6, 1902. By the Spey at Aviemore, Easterness, Miss 1. M. ROPER.
Spe C. E. Salmon in Journ. Bot., 14, 1929.
190/8(;3). A. CONTHOVEHSA Buser et Jaquet. Cave Hill, Belfast,
dIrs WEDGWOOD. "Identical with my Fribourg specimens determined
by Buser and myself after his controversy with me."-F. JAQUET.
