ovulatis; stylo brevi, filiformi; stigmate subcapitato. Drape succose, receptaculo subcarnoso v. spongioso 
baccatim congestee. 
One Bramble alone has hitherto been found in New Zealand, and it is, perhaps, the largest species of a genus 
which abounds in the North Temperate zone, and in the mountains of the Tropics, but is comparatively very rare in 
the southern hemisphere. The R. australis climbs the loftiest trees, often with Lygodium, presenting an impervious 
screen of round usually unarmed stems, and prickly leaves and panicles.—The leaves are extremely variable in size 
and form, ternate, quinate, or pinnate; the leaflets broadly ovate or linear-lanceolate, sharp, coriaceous, shining 
above, smooth or pubescent or even tomentose below, serrate, generally cordate at the base, 2-5 inches long, the 
petioles and midrib below usually bearing recurved prickles. Panicles branching, very many-flowered, terminal or 
axillary, 3-8 inches long, smooth or downy, unarmed or prickly. Flowers small, unisexual, whitish, $ inch across; 
pedicels pubescent. Caly« flat, downy, rarely smooth, five-lobed. Petals five to seven, rounded. Stamens very 
numerous, in one series, as long as the petals, usually absent in the female flowers, as are ovaries in the male. 
Ovaries numerous, twenty to thirty, seated on a spongy receptacle, with short styles and subcapitate stigmas. 
Fruit a small berry, smaller than a wild raspberry, formed of the numerous carpels, which become one-seeded drupes 
when ripe; it is then yellowish, and of a sweetish but austere taste. (Named from the Celtic rub, the root of rw- 
bella, red, from the colour of the fruit; and according to others, from reub, also Celtic, to tear, from the prickly stems.)

This again is a very large European genus, of herbaceous or half-shrubby plants; especially abounding in the 
mountainous districts of the northern temperate and sub-tropical regions, but almost unknown in the southern, except 
through the present plant, the common Silver-weed of England, which is quite a cosmopolite, extending from the lati- 
tude of 75° north to 56° south; varying, however, considerably in size. It forms a stemless herbaceous plant, giving 
off long runners from the root, and numerous pinnated leaves, which, as also the stems, are covered with long, shining, 
silky, often shaggy hair underneath, or on both surfaces. Leaves 3—6 inches long, unequally pinnate, with often 
small, tooth-like, scattered pinnules betwen the larger, which are in five to twenty pair, ovate, oblong or rounded, 
3-1 inch long, deeply cut. Scapes about as long as the leaves, erect, one-flowered, villous. Calyx very silky
