REVISION OF SECTION TOMENTOSA OF THE GENUS ROSA. 41 
Host. PI. Austr. (1831) ii. p. 21, "Foliola ovata, serrata, villosa, 
facie saturata, dorso pallide viridia." 
Hooker, Br. FL (1835) p. 234, describes R. scabriuscula, Sm., as 
R. tomentosa, a very different species and much more common in Eng- 
land than R. tomentosa. 
Petermann, PL Lips. (1838) p. 364, "Poliola 5-7, ovali-oblonga, 
cinerascenti-virentia, villosiusculo-pubescentia." 
Gonnet, PL Elem. de la France (1 847), p. 478, " Leaves ash- 
coloured, pubescent, cottony on both sides." 
Kirschleger, FL d'Alsace (1852), i. p. 49, " This species is distin- 
guished from R. canina by the generally soft tomentose greyish leaves, 
and by the straight horizontal and longish prickles ; and from R. pomi- 
fera by its ovoid smaller (half the size), red, erect, somewhat hispid, 
cartilaginous fruits, and by the elliptic-oval, never elliptic-lanceolate 
leaflets." 
Cosson and Germain, FL des Env. de Paris (1861), p. 221, " Leaves 
more or less ash-coloured on both sides, sometimes a little glandulose 
below, 5-7 leaflets." 
Cariot, Et. des Fleurs (1865), ii. p. 190, cc Leaflets tomentose on both 
sides, without glands below. " 
I close my inquiry with these principal English, French, and German 
Floras. There is certainly confusion among English authors as to R. to- 
mentosa. Smith probably established his species on a somewhat rare 
English form; then R. scabriuscula, Sm., became confounded with 
R. tomentosa, and these two species are united under the same name 
in books, and mixed in herbaria. 
M. Grenier, FL du Jura (1864), p. 234, says that he retains the 
name R. tomentosa for this species, because the English specimens 
which he has are identical with the French plant. M. Grenier could 
not have examined n. 1662, collected by himself and distributed by 
the late M. Billot, because at that time he did not venture to say 
that the English specimens were the same as the French plant, seeing 
that the specimens collected at that time, at Besa 119011, are far from 
having, as M. Grenier says (I.e.) "leaves covered with minute glands 
below ;" n. 16C2 having the leaves only tomentose and without glands. 
M, Grenier may take this view, but he must permit us to inquire 
how far it corresponds with the descriptions. M. Grenier quotes also 
Eng. Bot. t. 990, for his R. tomentosa, but this, which is simply
