310 ARBORETUM AND FRUTICETUM. _ PART III. 
Spec. Char., §c. Leaves in 4 pairs of 
leaflets with an odd one, thelow- 
er pairdistant from the base of the 
petiole ; leaflets ovate, approxi- 
mate, cordate at the base, one- 
nerved, spiny-toothed, with 9 or 6 
teeth oneach side. Racemes erect, 
and much crowded. Filaments bi- 
dentate. (Don’s Mill., adapted.) 
One of the handsomest of hardy 
evergreen shrubs, attaining the 
height of 6 ft. in 6 years, quite 
hardy, producing a profusion of ¢ 
bunches of yellow flowers during § 
April and May. It is a native of 
the north-west coast of America, 
tom New Albion to Nootka 
Sound, growing in rich vegetable 
soil among rocks, or in woods, ’ 
where it forms a thick and rich under-growth. It was introduced into 
England in 1823, and is to be found in all good collections: Accord- 
ing to Dr. Lindley, it is “ perhaps the handsomest hardy evergreen we 
yet possess. Its foliage is of a rich, deep, shining green, becoming purple 
in the winter; it bears fruit in some abundance, which consists of clus- 
ters of roundish black berries, having their surface covered with a rich 
violet bloom. It most resembles M. fascicularis, from which its large shining 
leaves at once distinguish it.” (Penny Cyc., iv. p.262.) This species is pro- 
pagated very slowly by layers, and, for some years, plants were sold im the 
nurseries at ten guineas each. Lately, however, a number of ripe seeds 
have been produced in England, or imported from America through the 
Hudson’s Bay Company; and from these, many young plants have been 
raised, in the Epsom and other nurseries; so that small plants may now be 
obtained for 5s. each, and in a few years they will, no doubt, not cost half 
that sum. In Prince’s Catalogue for 1825, the price is stated as 25 dollars 
(45/. 5s.) each.

the lower pair distant from 
the petiole; leaflets ovate, 
acuminated, and remotely 
spiny-toothed, somewhat 
3—5-nerved, with 12 or 14 
teeth on each side; ra- 
cemes elongated; filaments 
bidentate. (Don’s Mill., i. 
p- 118.) An evergreen un- 
dershrub, in its native 
habitats seldom exceeding 
the height of 3 ft., and 
producing its yellow flow- 
ers in October, succeed- 
ed by roundish fruit, of 
a glaucous-purple colour, 
and having an_ insipid 
taste. The plant is found in 
shady pine woods, on the
