134 NOTES ON ENGLISH KUBI.
VI. Stems arciude-prostrate or quiU jjrostrate, hearhuj pHcJdcs, acicidi,
and f/landular settc of different sizes. Basal leajlets stalked.
A. Intermediate acicuH scattered.
42. E. MUTABiLis Geiiev.—Frequent around Plymoutli, where I
saw it with Mr. Briggs.
Cont. distrib. W. France.
43. E. Bloxamii Lees. — Frequent around Bournemouth, in
S. Hants, and Dorset. It is closely allied to R. thyrsijionis W. et N.,
and perhaps the two species may run together.
Coitt. distrib. According to Genevier, W. France.
44. E. EosACEus W. et N.—I have seen dried English specimens
only, but from different parts of the country.
Co7it. distrib. N.W. Germany, Belgium, France (following
French authors, I have seen no French specimens).
B. Prickles, acicidi, and seta; of every size mixed.
45. E. HYSTEix W. et N. — In dry specimens it is difficult to
trace the limits between this species and R. Koehleri. I have not
seen living plants of either species in England.
Cont. distrib. N.W. Germany (very local !).
46. E. Koehleri W. et N.—See U. lujstrix.
Cont. distrib. The typical plant occurs frequently in the central
part of Germany, from the Eussiau to the Belgian frontier.
Varieties or nearly-allied forms are spread over the whole of Central
Europe. A small variety is R. Reuteri Merc.
47. E. ^^KIDIs Kaltenb. R. jxdlidus of many English authors.—
It is easily distinguishable from the true R. paUidus by the abundant
intermediate aciculi on the stem and the rachis. Mr. Briggs
showed me a plant near li. viridis in the Common Wood, Bickleigh,
S. Devon.
Cont. distrib. W. Germany.
48. E. mRTUs W. K. (aggregate). — In S. Devon I have seen
several forms of this group. It would be a useless attempt to
arrange these English plants under one or the other continental
subspecies or varieties.
Cont. distrib. of th© hirtus group. Western, Central, and Southern
Europe ; Asia Minor.
VII. Stems arcuate-2nostrate or quite jy^'ostrate, armed in a various
maJiJier. Basal leaflets nearly sessile.
A. Prickles, acicidi, and setce unequal and very abimdant.
49. E. DivERsiFOLius Lindl. — Seen at different places in
S. Hants and Dorset, near Bournemouth ; Fursdon, S. Devon.
Eesembles R. Koehleri, but I think it is nearer the Corylifolian
group. The R. dumetorinn ferox W. is not quite the same, but
I think my R. myriacanthus will fall under R. diversifolius.
Cont. distrib. N.W. Germany (/i. myriacanthus).
