ARBORETUM ET FRUTICETUM BRITANNICUM. 



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.,\s. p. 262.) Layers and seeds.

 Introd. in 1822. Flowers 

 yellow ; October to March 

 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. Eacemes spi- 

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

 larger than in M. yJquifolium. 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 siiady border of peat soil. One of 

 the handsomest of undershiubs.
