ROSA GRENTERII 63 
linear, with foliaceous tips, pinnate, glandular on back. The 
same number in the British collection has its leaflets plainly but 
thinly glandular beneath; the fruit is aciculate on the whole 
upper half or two-thirds.

Déséglise, Essai Monogr. p. 128 (1861). 
“Shrub with slender prickles, compressed at base, long, 
straight. Petioles tomentose, glandular, prickly beneath. Leat- 
lets 5-7, oval elliptical, obtuse or acute, firm, greenish, softly villous 
above, greyish tomentose beneath with shining villosity, nerved, 
doubly dentate, with ciliate glandular teeth, the lateral petioluled, 
the terminal rounded at base. Stipules glabrous above, tomentose 
beneath. Auricles acute, diverging. Peduncles short, solitary or 
in a small corymb, hispid, with bracts at base pubescent above, 
tomentose and scattered glandular beneath, longer than the 
peduncles. Calyx-tube swbglobular, hispid with small setaceous 
spines ending in a gland. Sepals glandular, tomentose on edges, 
lanceolate, spatulate at apex, entire or two with 1 or 2 short lobes, 
reflexed in flower, then erect, persistent. Styles short, villous. 
Flowers small, rose, yellowish in middle (I have not seen them 
in its smaller oval elliptical not oblong lanceolate leaflets, with 
stronger more shining villosity; calyx-tube hispid with fine sete, 
Which are less numerous and half shorter; fruit smaller, red, 
variety of R pom) era, yeu thevery v 
merated by Déséglise, with the exception of the shining villosity, are 
those which distinguish mollis therefrom, moreover the specime 
have seen of R. Grenierii recall R. mollis rather than FR. pomt- 
fera. It is chiefly for this reason, and on account of the existence 
of several other intermediates, that I decided to unite mollis and 
pomifera in one group. Crépin, in Bull. Soc. Roy. Bot. Belg. xxl. 
p. 104, says R. Grenierii is simply a series of forms between the 
two, often with fine subfoliar glands, a feature not confirmed by 
unequal prickles and subentire sepals. Perhaps broader stipules, 
with deltoid auricles, rather smaller more finely serrate leaflets, 
and less deep rose flowers are features which may assist in its 
diagnosis. It occasionally runs into forms with rather narrowly 
elliptical leaflets, narrowed at each end.
