ROSA CANINA VAR. CONCINNA 83 
(f. collina Lloyd) are obvious aber hybrids, having the charac- 
teristic aciculate armature of that group. 
R. collina “ Jacq.,” as = ene by Mr. Baker in Seemann 
Journ. Bot. iii. p. 52, has been shown to be BR. lewcochroa Deir is 
see Journ. Bot. 1877, p: 316. 
. Kosinciana auct. angl. is certainly not Besser’s species, the 
latter having glabrous leaflets, and being allied to R. andegavensis 
Bast. There is so much variation in British ee labelled 
i. Kosinciana that I am unable to say what it is 
Rosa CANINA var. CONCINNA 
Baker in Monograph of British Roses, p. 233 ae 
“Prickles very much hooked. Leaflets very small, the ter- 
minal one 8-9 ag long, flat, broad, obovate, thinly ceca i 
when young, hairy all over beneath ; the teeth simple, 5 i ae 
open ; her petioles pubescent, but scarcely at all setose; the calyx- 
tube s: broad, ovate ; the styles slightly stern thinly 
hairy. wrTho representation of the Continental obtusifolia in this 
group” [i. e. Series Heristate, with aciculate peduncles] . 
I have not seen a specimen of this collected or named by 
Baker, the only one I have seen at all being one of Briggs, from 
Honicknowle, near Plymouth. It has rather large, moderately 
stout, much hooked prickles; leaflets large, very broad, rounded 
or narrowed below, ne genoa hairy — sides, or = on above 
Some peduncles quite gland anlar’ setose, others only otigtly 
Fruit small, ovoid. Styles protruded, loose, subglabrous. Sepals 
much pinnate, glabrous or slightly hairy on bac his specimen, 
it will be seen, agrees very well with Mr. Baker’s description, 
except for its large leaflets; if they were ‘very small” it would 
certainly run near R. obtusifolia Desy. with hispid peduncles. 
No foreign author mentions it, and the nearest Continental 
colours of those of var. concinna not being stated.
