Mountains in the north of England, and especially Scotland. On 
Brandon mountain, Ireland. 7). 6 — 8 — One of the most elegant 
of our native plants. Flowers in interrupted spikes of small terminal 
or lateral corymbs. Stam. 4. Our /9. is said to have been found 
wild in the Clova mountains by Mr. G. Don, and in Glen Sannox, in 
the Isle of Arran, both in Scotland: it has been for long a well- 
known denizen of our gardens, under the name of A. bybrida ; but 
although it retains all its characters in cultivation (proving it to be a 
permanent variety), it appears to us to differ too little from the 
usual form of the species, to be admitted as distinct: in this genus, 
and even this order, the leaflets are not jointed with the petiole, and 
consequently, according to the view of De Candolle, do not form a 
compound leaf, but merely portions of a simple one : in a. therefore 
the leaves are only divided to the base : in /8. to near the base : there 
is no other difference. The fig. in E. Bat. seems to belong to the var. fl. 
3. A. arvensis Sm. ( field L., or Parsley Piert ) ; leaves trifid 
pubescent, lobes cuneate deeply cut, flowers sessile axillary. 
E. B. t. 1011. Aphanes. L. 
Fields and gravelly soils, and on wall-tops, where there is any 
covering of soil. Q. 5 — 8. — Stems branched, leafy, 4 — 8 inches long, 
frequently prostrate. Leaves alternate; stipules large. Stam. varying 
in number from 1 — 4. Germens 1 or 2. 
** Style nearly terminal. Ovule suspended. 
11. Sanguisorba Linn. Burnet. 
Flowers collected into a head, usually perfect. Cal. 4-lobed, 
superior, coloured, with 2 — 4 scales or bracteas at the base. 
Pet. 0. Stam. 4. Stigmas capitate, papillose. Achenes 1 — 2. 
Named from sanguis, blood, and sorbeo , to take up, or absorb ; 
from the supposed vulnerary properties of the plant. 
1. S. officinalis L. {great B.) ; glabrous, stamens about as long 
as the perianth. — a. spikes ovate. E.B.t. 1312. — /3. spikes 
cylindrical. S. media Sm. 
Low moist meadows and pastures, on a calcareous soil ; chiefly in 
the north of England ; more rare in the Lowlands of Scotland /3. 
West of Scotland. If.. 6 — 8 Stem 1 — 2 ft. high, branching upward. 
Leaves pinnate ; leafl. ovate, somewhat cordate at the base. Heads 
of flowers much crowded, dark purple. Limb of the perianth in 4 
ovate segments, its tube enveloping the germen and having at its base 
4 ciliated scales or bracteas ( calyx of many authors). Achene 1, rarely 
2. We have not seen the var. (}. : it cannot be S. media L. as sup- 
posed by Smith, that being a N. American plant with long stamens 
and a mere var. of S. Canadensis. 
12. Poterium Linn. Salad-Burnet. 
Flowers collected into a head, monoecious or polygamous; 
upper ones fertile. Cal. with 3 or 4 bracteas at the base. Pet.
