quantity in hedges and thickets in the neighbourhood of Plymouth, and 
as the stations are upon both sides of Taraar, they are consequently 
botli in Devonshire and Cornwall. The following description is taken 
entirely from his specimens and notes ;— 
Jiosa (Series CaniNjE — Section Hispit).e) colllna, Jacq. Austr. tab. 
197. A shrub, six to ten feet high, with arching shoots and the habit 
and appearance of R,ca?ihia, Prickles uniform, uucinatCj moderately 
robust below, measuring about three-eighths of an inch from base to point 
upon the full-grown stems. Leaves similar in size to those of jS. canlna^ 
firm in texture, full green and quite glabrous above, paler beneath and 
hairy on the veins, the serrations moderately sharp and open, simple or 
sometimes a little unequal, the terminal leaflet typically ovate, the petiole 
haiiy and aciculate, but only slightly setose." Stipules naked or very 
sligbtly hairy on the back, faintly setoso-ciliated. Peduncles rather thickly 
beset with strong setas, the calyx-tube gracefully ovate-urceolate, naked 
or just setose at the base. Sepals fully piunate, naked on the back, very 
slightly setoso-ciliated, reflexed after the whitish petals fall, deciduous 
before the ovate-urceolate fruit changes colour, which near l^lymouth 
is early in September. Styles glabrous or very nearly so. 
The plant appears to be widely difl'used over the Continent, as there 
are records of its occurrence from Piedmont northward to Scandinavia, 
and from Prance eastward to the Caucasus. There is an original ex- 
ample from Jacquin in the Linn^an herbarium, which I have examined. 
This has more hairy styles and a shorter and more prickly calyx-tube 
than the English specimens. I have seen it from various stations 
in Savoy, Switzerland, France, and Germany. It is the coU'ma of 
Gmeliu, Persoon, Eau, Trattinick, Eeichenbach, Allioni, Willdenow, 
Pries, Boreau, and Dcseglise; the canina^ var, colUna, of Lindley, Se- 
ringfi, Koch, Grenier and Godron, Keuter, Kapiu, and numerous other 
authors. M. Dcscglise describes his typical plant as furnished with 
, 'woolly styles, but notes that specimens from Angers have glabrous 
'Styles, in combination with leaves a little doubly serrated. Fries as- 
signs to it cernuous mature fruit, but in our plant the peduncles, which 
in the specimens I have seen vary in number from one to eight in a 
cluster, are always erect. Deseglise says that the midrib of the leaves 
beneath is furnished sparingly with glands. This I do not see in our 
specimens, which have also a less setose petiole than the Continental 
examples I have s^eu, including that oF Jacquia. I have not seen
