Corylus 



CORTADERIA. 



The Spanish name for the Pampas Grass, gener- 

 ally known by the name of Gynerium argenteum, 

 and its conveners. They are described in this 

 work under Gynerium. According to some author- 

 ities, Cortaderia argentea is the correct name of 

 Gynerium argenteuni. 



CORTUSA. (BEAR'S EAR SAXICLE.) 



Pretty little perennials (ord. Primuluccie) for the 

 rock garden, but requiring winter protection from 

 damp. They are increased by division of the 

 roots, or by seeds sown in a frame in spring, and 

 grow in a soil composed of loam, peat, and sand. 

 The species cultivated are Matthioli, 1', April, red ; 

 grandill.ira, a variety of .Matthioli, H', April, purple,' 

 very fine ; and pubens, 0", May, magenta purple. 



CORYANTHES. 



A genus of Orchids allied to Stanhopea (ord. 

 Orohidaoese) remarkable for the strange form of 

 their flowers. Propagated by division of the pieces, 

 and offsets. Fibrous Orchid peat and sphagnum in 

 equal proportions, with the addition of finely broken 

 crocks, make a suitable compost. The various 

 species must be grown in Teak baskets under the 

 warmest treatment given to Orchids, with plenty 

 of atmospheric moisture, as well as water at the 

 roots in summer, and a little less in winter.

CORYCIUM. 



Terrestrial greenhouse Orchids (nrrl. Orchidacens), 

 the cultivation of which has not yet been thoroughly 

 mastered, the plants dying after a time. Increase 

 by imported tubers. Soil, three parts fibrous peat, 

 one part loam, with plenty of sand.

CORYDALIS. (FUMITORY.) 



Desirable hardy perennial or annual plants (ord. 

 Funiariacese), with prettily shaped flowers, and of 

 great value for borders and rockwork. Propagated 

 by seeds in the case of the perennials and annuals ; 

 by division after flowering for the herbaceous; and 

 by offsets for those with tuberous roots. They 

 generally prefer a rather moist and peaty soil, but 

 some will even thrive on a damp wall. Lutea is 

 one of the best for a wall. 



Principal Species :

CORYLOPSIS. 



Hard}' shrubs or small trees (ord. HamamelidesE), 

 much benefited by the shelter of a wall in all but 

 the more favoured parts of the country. Flowers 

 in advance of the leaves. Propagated by cuttings 

 of half-mature wood in summer, in gentle heat; 

 also by seeds when obtainable ; and by lavrr- in 

 autumn. Any ordinary garden soil, well drained.
