and on a shorter and thicker stalk. This latter is the more 
frequent variety, or rather series of varieties, filling up the interval 
between the sour Crab and the Garden Apples; and no doubt it is 
often produced directly from the latter, if not always so. I have 
seen the acerba certainly in Surrey and Cheshire, and very 
probably in other counties, without making special notes of it. 
In English Botany we are told that it is “not unfrequent, and 
generally distributed in the south and midland counties of 
ee but that it has never been seen in Scotland by the 
ditor. 
Pyrus (Aria) eu-Aria, Syme in E. B. 38. 
Provinces 123-5. (Teesdale. Scotland.) 
Syn. 365. This segregate unfortunately has been labelled “ scan- 
dica” by some botanists, and thus the recorded localities of the 
two have become confused in books. 
Pyrus (Aria) rupicola, Syme in E. B. 8. 
Provinces 1 - - - - - 78-1011--14---18, 
Syn. 365. Devon to Sutherland; Eng. bot. This is the Aria of 
many botanists; and really I do not see how to distinguish it 
satisfactorily from the eu-Aria. 
Pyrus (Aria) scandica, KE. B. 3. P. intermedia, Ehrh. 
Provinces 128-5-7--1011. Partly errors? Arran? 
Syn. 865. Cyb. iii. 348. Bot. Gaz. iii. 34. The line of separa- 
tion between this segregate and Aria or eu-Aria, on the one side,— 
between this and pinnatifida or fennica, on the other side, is traced 
differently by botanists. Specimens from Arran have very usually 
been labelled as pinnatifida or fennica; but Dr. Boswell Syme 
informs me, while these pages are going through the press, that 
the Arran species is scandica not fennica. 
Pyrus (Avia) pinnatifida, Sm. P. fennica, Bab. man. 
Provinces 123-5--8----- 14 16. Partly alien. 
Syn. 867. Cyb. iii. 347. Wild in Arran, subject to the recently 
formed opinion of Dr. Syme that it is scandica, not fennica, which 
occurs there. Mr. Borrer held it wild also in North Hants, 
between Farnham and Farnborough; where it was observed 
sparingly along with Aria and Aucuparia, both more plentifully. 
A specimen in my herbarium was picked by Mr. James Macnab 
in Darenth Wood, Kent; and this I cannot separate from Arran 
examples distributed by Professor Balfour and Mr. Bell through 
the Botanical Society of Edinburgh. For the present I must 
dissent from the changed opinion of Dr. Syme, by regarding the 
Arran pinnatifida (Sm.) as the same species with specimens sent 
me from Sweden labelled hybrida and fennica; not the same with 
others also sent me thence labelled as scandica. Both these 
apparent species differ evidently from ew-Aria and rupicola of 
Syme, by their venation and tomentum.
