WILSON's OBSERVATIONS, 259 
of its prismatic stem, and slender straight deflexed prickles ; 
but never found out of woods or shady situations ; and as R. 
affinis is not to be found in woods, I cannot help suspecting 
them to be varieties, depending solely upon their situation, 
and not permanent when removed. I have seen both in 
plenty, growing only a few yards from each other. 
64. Rubus glandulosus ; an intelligible variety, character- 
ized by its glandular calyx, and flower-stalks, the latter plen- 
tifully supplied, in general, with straight spreading prickles 
just below the calyx, which is generally prickly. 
65. Rubus nitidus ; probably a state of affinis, depending 
on situation for its characters; frequent on stony barren dry 
ground, or where the soil is peaty, while on the adjoining 
hedges, in richer ground, more plentifully supplied with 
moisture, R. affinis is almost sure to be found. 
66. Rubus swberectus ; a good species, already well under- 
stood—grows in Cheshire. 
67. Rubus ideus.—June, 1827. The prickles on the 
flower-stalk are a little bent, as mentioned in Lng. 77. ; but 
those of the calyx are straight. 
68. Rubus corylifolius, The broad segments of the calyx 
seem to be most commonly wide spreading in the half-ripe 
- fruit, as well as in the flower. 
69. Rubus cesius. However easy it may be in general to 
recognise this plant, some states either of this or of coryli- 
Jolius are found which make it somewhat doubtful whether 
they do not pass into each other; but for the present I 
should propose to keep them distinct as varieties. The 
convergent, bristly, calyx is the best mark. 
10. Potentilla verna, Ormeshead, May 17, 1826, 1828, I 
do not find the leaves rigid or coriaceous, nor, in general, 
' very distinctly furrowed along the ribs and veins—neither 
can I perceive the interior segments of the calyx to be three- 
ribbed. The leaves are sometimes hairy on the upper surface. 
The large specimens found in Llandudno Bay (very little 
above high water mark) have confirmed my previous suspi- 
cion that it is not specifically distinct from P. alpestris.
