Mespilus.'] XXVII. ROSACEiE : P03IEA5. 
E. B. t. 2367. — /?. incana; prickles strongly uncinate from a 
much lengthened base, peduncles hairy, leaflets hoary beneath, 
fruit large oblong. 
Highland valleys of Perthshire and Argyleshire. Northumberland 
and Durham. fl. sent from Scotland to Mr. Sabine, b . 6, 7. — 
We do not distinguish this from R. canina. 
|| Styles united in a column, mostly cxserted. 
18. R. sy stylo. Woods ( close-styled D.) ; prickles uniform 
uncinate, leaves simply serrate, their disk eglandulose, calyx- 
segments sparingly pinnate deciduous, styles united hairless, 
shoots assurgent. R. collina E. B. t. 1895. ( excl . syti .) 
Thickets, hedges, &c. Sussex, Essex, Middlesex, Berkshire, Kent. 
Niddrie; hills to the north of Milngavie ; and Fort Augustus; 
Scotland. Near Cork. b . 6, 7. — Mr. Bentham considers this to 
be a form of R. canina. 
19. R. arvensis Huds. (trailing D .) ; prickles uncinate, those 
of the ramuli feeble, leaves simply serrate deciduous (glauces- 
cent beneath), their disk eglandulose, calyx-segments sparingly 
pinnate deciduous, styles united hairless, shoots trailing. E. B. 
t. 188. 
Woods, hedges, thickets, &c. ; common in England, but rare in the 
mountainous districts. Lowlands of Scotland. Near Bray, Ireland, 
b . 6, 7. — This is distinguished from all the other British species 
by its trailing habit ; and from R. systyla, so far as we can see, by 
that character alone. It is frequently cultivated under the name of 
Ayrshire Rose ; but the true one (A. capreolata Neill) has, we believe, 
the column of styles slightly hairy and shining leaves, and is consi- 
dered by Sabine a deciduous var. of R. sempervirens, although it is 
more probably a hybrid between that species and R. arvensis. 
Sub-Ord. III. POME2E Lindl. Fruit consisting of several 
united carpels adhering by their back to the inside of the ca- 
lyx-tube and forming an inferior 1 — 5-celled pome , the cells

nate , simple or divided , with free stipules. Flowers in terminal 
cymes, white ov pink. (Gen. 15 — 18.) 
15. Mespilus Linn. Medlar. 
Cal. segments large, foliaceous. Pet. large, roundish. Disk 
large, secreting much honey. Styles 2 — 5, glabrous. Fruit tur- 
binate, with the upper ends of the cells, which are bony, ex- 
posed. — Named from pta-iKp, the Greek word for medlar. 
1. M. * Germunicu L. (common 31.) ; leaves lanceolate a little 
downy, flowers solitary nearly sessile terminal, styles 5. E. B.
