Genus Rosa in Warwickshire..
The Caninæ, which Mr. Baker considers to be only varieties of one species, are divided into three series, and each of these series into several varieties, by means of their fruit characters, the margination and clothing of their leaves, &c. My space is too limited to allow all these details ta be noticed, and I can only refer the student who wishes to make a special study of the genus to Mr. Baker's excellent monograph, or to Dr. Hooker's "Student's Flora of the British Islands."
In all cases in which I have seen and collected specimens in the stations cited I have indicated it by this sign (†); where I only posses or have seen dried specimens, thus {‡). The initials A. B. and H. B. alter a locality indicate that the plants have been found in these stations by the Rev. A. Bloxam or Mr. H. Bromwich, as the case may be; in all other cases the localities given are from my own note book.
Rosa Spinosissima, (L.) Local. Arrow, near Alcester †, Billesley †, Hazeler †, Oakley †, H. B., near Warwick.
Var. b, a form with aciculute fruit and peduncles is rare. Chesterton Wood ‡ ‡;, H. B., Little Alne †.
R. involuta var. Sarini, (Woods.} Rare. Oakley ‡, H. B., Chesterton Wood ‡, H. B.
