Viburnum. ] XXXIX, CAPRIFOLIACEA. 209 
Several exotic species of both sections are much cultivated. 
1. L. Periclymenum, Linn. (fig. 466). Common H., Woodbine.—-A 
woody climber, scrambling over bushes and trees to a considerable 
height. Leaves ovate or oblong, glabrous above, usually slightly downy 
or hairy underneath ; the lower ones contracted at the base or stalked, 
the upper ones rounded and closely sessile, but not united. Flowers 
several together, closely sessile in terminal heads, which are always 
stalked above the last leaves. Corolla about 14 inches long. Berries 
small and red. 
In woods, thickets, and hedges, in western and central Europe, from 
southern Scandinavia to the Mediterranean, but not extending to the 
Russian frontier. Common throughout Britain. Jl. summer and 
autumn. 
2, L. Caprifolium, Linn. (fig. 467). Perfoliate H—Very much like 
L. Periclymenum, but quite glabrous ; the leaves broader, the uppermost 
pairs in the flowering branches united at the base, and the heads of 
flowers closely sessile within a pair of leaves united into a single broadly 
rounded perfoliate leaf; or the flowers are sometimes separated into 
two tiers, with a perfoliate leaf under each. 
In hedges and woods in central and south-eastern Europe, and per- 
haps western Asia, but often confounded with the two common southern 
species, L. implexa and L. etrusca. Not truly wild in Britain, but long 
since cultivated for ornament, and almost naturalised in some counties 
in England and the south of Scotland. Fl. spring and early summer. 
3. L. Xylosteum, Linn. (fig. 468). ly H.—An erect, much 
branched shrub, 3 or 4 feet high, of a pale green, and downy in all its 
parts. Leaves ovate, entire, and stalked, about 14 inches long. Flowers 
of a pale-yellowish white, downy and scentless, only 4 or 5 lines lone, 
hanging 2 together from short, axillary peduncles, with 2 small narrow 
bracts close under them. Berries bright scarlet, with 2 or 3 seeds in 
each. 
In thickets and hedges, almost all over Europe and Russian Asia, 
extending northward to the Arctic Circle. Dispersed over various 
parts of Britain, generally as an escape from cultivation, but believed 
to be really indigenous in some parts of south-eastern England. It is 
very common in our shrubberies. Fl. early summer. 
V. LINNZAA. LINNAGA. 
Calyx with a border of 5 teeth. Corolla campanulate, 5-lobed, 
narrowed at the base into a short tube. Stamens 4. 
A genus of a single species, dedicated to the great master of natural 
science, with whom it was an especial favourite. : 
1, L. borealis, Gronov. (fig. 469). Zinnwa.—A slender evergreen, 
creeping and trailing along the ground to the length of a foot or more. 
Leaves opposite, small, broadly ovate or obovate, and slightly toothed 
at the top. Flowering branches short and erect, with 2 or 3 pairs of 
leaves, and terminated by a long slender peduncle branched near the 
top into 2 pedicels, each bearing an elegant, gracefully drooping, and 
fragrant flower of a pale pink or white colour, above 5 lines long. 
Ovary globular and very hairy, the rest of the plant more or less
