when ripe. There is a dwarf variety called pygmcea, and a few other 

 species not so well known. Easily raised from seeds, and grows in any 

 poor soil. Suitable for railway embankments and such places. 



Comptonia (Myrica) asplenifolia (SWEET FERN). A distinct North 

 American shrub, 3-4 ft. high, having sweet-scented deciduous Fern-like 

 leaves and small flowers. It flourishes in moist peaty soil, and is increased 

 by layers, offsets, suckers, and seeds. 



Coriaria myrtifolia. A pretty South European shrub, 3-6 ft. high, 

 with Myrtle-like leaves and small greenish flowers, succeeded by fleshy 

 poisonous berries. C. terminates has drooping branches, laden with clear 

 golden berries in autumn; and C. japonica has bright- red fruits. In- 

 creased by seeds, layers, and suckers. 



Cornus (CORNEL, DOGWOOD). There are several more or less orna- 

 mental shrubs belonging to this genus. C. alba, 10 ft., has creamy-white 

 flowers and white fruits. The variety Spdthi is a fine foliage plant, the 

 leaves being bronzy in spring, changing to green with an irregular golden 

 border in summer. C. capitata (perhaps still better known as Benthamia 

 fragifera) is the "Strawberry Tree" of Northern India and China. It 

 grows 40 ft. high in favoured spots, and has clusters of white flowers 

 succeeded by large globular red fruits composed of many hexagonal 

 drupes. C. florida is the " Flowering Dogwood " of the United States. 

 The greenish-yellow flowers have four large white bracts. C. Kousa 

 (Benthamia japonica), from Japan, is a beautiful shrub, with large white 

 bracts. C. Mas (or Mascula) is the Cornelian Cherry, 10-15 ft., with 

 yellow flowers from February to April. It is very largely grown, and 

 has several varieties, including variegata, with green and silvery foliage; 

 elegantissima, creamy white tinged red; and aurea tricolor, with white, 

 red, and yellow shades. C. sanguinea, the Common Dogwood of Britain, 

 is remarkable for the deep vinous red of its stems so conspicuous in winter. 

 Its creamy-white flowers are succeeded by small black berries. There are 

 several varieties, including a variegated one. 



Coronilla Emerus (SCORPION SENNA). An elegant somewhat hairy 

 South European shrub, 3-6 ft. high, with pinnate leaves and clusters of 

 yellow pea-like flowers. Increased by seeds or cuttings. 



Corylus (HAZEL). The Common British Hazel or Filbert (C. Avellana) 

 grows to a height of 20 ft. or more, and is highly valued. It has several 

 varieties, including purpurea, with rich -purple leaves; aurea, golden; 

 heterophylla or laciniata, deeply cut; and pendula, weeping. The com- 

 mon kind is easily raised from seeds, and the varieties are grafted on it, 

 or are layered. C. Columa, 30-60 ft., from Asia Minor, grows well in 

 parts of the British Islands. It has whitish flaky bark, and roundish 

 heart-shaped leaves. 



Cotoneaster. A genus of very ornamental shrubs, some being ever- 

 green, others deciduous, but all useful for garden or rockwork decoration, 

 or for forming game coverts. The flowers in all cases are white and 

 Hawthorn-like, and bright-red or crimson fruits appear in autumn and
