510 24, ROSACEA. 
Poterium (muricatum) platylophium, Jord. 
Provinces 123-5. “Som. Wight. Warw.” And elsewhere. 
Syn. 355.* Not clear to me, apart from the next. 
Poterium (muricatwm) stenolophium, Jord. 
Provinces - 84. “Newmarket, Cambr.” ‘St. Margaret's, Kent.” 
Syn. 355.* “There is so much difference between the fruits of 
the two forms, that very probably they ought to be separated 
as sub-species”; Eng. bot. iii, 135. But a specimen from St. 
Margaret’s, given to me labelled “ stenolophium” by Dr. Syme 
himself, has the “denticulated” wings attributed to platylophium 
in Eng. bot. 
Alchemilla (vulgaris) montana, “ Willd.” 
Provinces --845--8910--131415. Midx. to Aberdeen. 
Syn. 356. Eng. bot. iii. 188. Glot. flo. 25. Among the specimens 
of A. vulgaris, promiscuously in my British herbarium, I find 
those with the “petioles and under-side of leaves pilose” are more 
numerous than are those with the same parts “ sub-glabrous”; 
and so far it would seem that the alternative variety “ genuina” 
may be the less usual form. 
Alchemilla conjuncta, Bab. 
Provinces - 7-12-15 16. See pages 469—70 of this volume. 
Ambiguity. Cyb. i. 868. iii. 423. Eng. bot. ni. 139. 
Mespilus germanica, Linn. 
Provinces 12345---9 10. 
Alien? Cyb. i. 864. iii. 424. Some reliable botanists hold this 
tree to be truly native in England. 
Crategus (Oxyacantha) oxyacanthoides, Thuil. 
Provinces - - 3 - - ---- 10(11---15). And elsewhere. 
Syn. 860. Usually this has not been well distinguished in books ; 
the aggregate name “ Oayacantha” being set against the segregate 
name monogyna or ertocarpa. Tn Surrey this appears equally wild 
with the latter or type variety; but it is less frequent, and 
certainly less sown. 
Pyrus (communis) Achras, ‘‘ Boreau,” E. B. 3. 
Province -- 8. And elsewhere? 
Syn. 862. In English Botany this is separated as a sub-species 
from the commoner variety there named Pyraster. The evidence 
for it, as a tree really wild in England, is most unsatisfactory. 
Pyrus (Malus) acerba, DC. 
Provinces - 23-5---9. [Scotland ?] 
Syn. 863. Two chief varieties of Crab-Apple are found in hedge- 
rows and copses. The true or austere Crab has nearly glabrous 
leaves, with small very sour fruit on slender pedicels. The wilding 
Apple has the under-side of the leaves and other surfaces clothed 
with cottony pubescence; its fruit is usually larger and less sour,
