ARBORETUM ET FRUTICETUM BRIT AN NI CUM. 



One of the handsomest of 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. In its native country it grows in rich vegetable 

 soil, among rocks, or in woods, where it forms a' thick and rich undergrowth. 

 According 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 

 clusters 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.) Layers and seeds.

Spec. Char. y fyc. Leaves of 

 5 6 pairs, with an odd 

 one, the lower pair distant 

 from the petiole; leaflets 

 ovate, acuminated, and re- 

 motely spiny-toothed,some- 

 what 3 5-nerved, with 12 

 or 14 teeth on each side. 

 Racemes elongated. Fila-

 Mill.} An evergreen un- 

 dershrub. North-west of 

 N. America, on the river 

 Columbia, in shady pine 

 woods. Height 2 ft. to 3 ft. 

 Introd. in 1822. Flowers 

 yellow ; October to March. Berries roundish, glaucous purple, or deep 

 blue ; ripe in July. 



According to Torrey and Gray, the stem is so low, that it often scarcely 

 rises from the ground, and, indeed, is much shorter than the leaves, which 

 are 1 ft. to 2 ft. in length. Racemes spi- 

 cate, often 6 in. to 8 in. long. Flowers 

 larger than in M. yiquifolium. The pe- 

 tioles of the leaves, Dr. Lindley says, 

 "are jointed at every pair of leaflets, 

 in the manner of a bamboo stem." 

 The plant is hardy, and will thrive in 

 a shady border of peat soil. One of 

 the handsomest of undershrubs.
