Rosa DEsEGLISEI 
Boreau, Flore du Centre de la France, iii. p. 224 (1857). 
‘A low shrub, with diffuse flexuous branches. Prickles small, 
with elongate discoid bases, arched or falcate. Petioles villous- 
tomentose, prickles or unarm arrow, 
villous beneath, fringed with some glands at the tip. Leaflets 5, 
small, pale green, villous above and more so beneath, oval acute, or 
scent, pinnate, with foliaceous appendages, short. Styles short, 
hispid. Disc a little conical. Fruit small, ovoid or roundish. 
Flowers small, light rose.” 
: église, in “Essai Monographique,” p. 128, gives an almost 
identical description, but says that the sepals are first reflexed, 
then erect, but deciduous. Also that it differs from R. dwmetorum 
in its oval acute leaflets, glandular and villous peduncles, pubescent 
sepals, and smaller roundish fruit. 
The peculiarity of this species is that its peduncles, though 
sometimes weakly glandular, are almost always more or less 
airy, which character only exists exceptionally in most other 
es 
T have not seen a specimen named by Boreau, and the majority 
of those placed in the R. Deseglisei cover by Déséglise exhibit 
such great variations, and have been labelled by their collectors 
with such a variety of names, that it is impossible to generalize 
e 
on three sheets are small, on two medium, and on one large; they 
are fairly regularly elliptical, and only subacute, rather rounded at 
the base; they are simply serrate, and very thinly hairy above,
