naming provisionally semiglaber, n. var., and distinguish by the follow- 
ing characters ; — Stem usually (piite glabrous. Mature leaves nearly 
naked beneath. Panicle usually broader and less straggling than in 
the type, with much less hairy rachis, larger flowers, and more ascending 
fruiting sepals. Prickles usually at least as densely crowded, and very 
unequal, but not quite so patent, and with fewer very long ones inter- 
mixed. Mr. Linton’s Aran Mawddwy plant differs from this variety 
in being considerably more hairy, and from both type and variety by 
its larger, more coarsely toothed leaves, and by the presence of some 
more or less falcate prickles among the patent and slightly declining 
ones. On the whole, however, it seems nearer to R. Marshalli than 
to R. Koehler ir—WL M. R. . 
Rubiis Marshalli^ Locke and Rogers, W. M. Rogers. Clearing on 
hillside at the base of the debris on the north side of the Penrhyn 
Slate Quarries, near Bethesda, North-east Carnarvonshire, 27th 
September, 1895. — Chari.es Bailey. “The form described above 
as semiglaber, n. var.” — W. M. R.

Jno. E. Griffith. “ Placed under R. hirtus^ I think, by Dr. Locke, 
and I am not prepared to question the determination (or suggestion ?) ; 
but it is, of course, very strongly armed even for the stronger forms 
of that most variable species, while in some particulars it recalls our 
A^ cognatus and forms of R. hystrix.’’^ — W. M. R. 
R. hirtus, K . and K.,a form. Near Treffos, Anglesey, August, 1895. 
Jno. E. Griffith. “ The glabrous angular (sometimes even sulcate) 
stem and deeply incised serrate leaves take this, I think, from 
R, hirtus and connect it with R. Durotrigum, R. P. Murray. 'Phe 
stem, no doubt, is often more sulcate here than in the Dorset 
Durotrigum, and perhaps usually more densely aciculate and with 
rather fewer gland-tipped organs ; the leaves are mostly smaller, 
narrower, and hairier beneath, and the panicle more leafy upwards ; 
but all the more marked features (and they are very striking) are 
common to the two plants, and the differences may well be due to 
locality, the exposed ground in Anglesey being exceedingly unlike the 
woodland habitat of the Dorset plant. R. Durotrigum has hitherto 
been found only in Dorset.” — W. M. R. 
R. hirtus, W. & K., var. rubiginosus, P. J. MuelL, near Glasinfryn, 
Bangor, Carnarvonshire, August, 1895. — J^o. E. Griffith. 
“ Named by Dr. Locke ; but these specimens are exceptionally 
weak and uncharacteristic, especially in some of the stem pieces.” —

intermediate between it and vscc. ferox, Weihe.” — W. M. R.
