CLE'THRA. (From klethra, the Greek 

 name of the Alder , alluding to a sup- 

 posed resemblance between their leaves. 

 Nat. brd., Heathworts [Ericaceae]. Linn., 

 W-Decandria, \-Monogynia. Allied to 

 Andromeda). Cuttings of half ripe 

 shoots of the tenderer species, in April, 

 under a bell-glass, and in sand. The 

 North American species are hardy enough 

 for our shrubberies; are propagated by 

 layers in autumn, or by firm cuttings in 

 sand, under a hand-light, in summer; 

 for all, peat is necessary.

CLEYE'RA. (Named after Dr. Cleyer, 

 a Dutch botanist. Nat. ord., Tlwads 

 [Ternstroniiaceae]. Linn., \S-Polyan- 

 dria, \-Monogynici). Greenhouse ever- 

 green shrub. Cuttings of half ripe 

 shoots, in sand, under a bell-glass; sandy 

 fibry peat. Summer temp., 60 to 70 ; 

 \*dnter 45 to 50. 



C.Japo'nica (Japan). 5. Yellowish white. 

 Japan. 1820. 



CLI'ANTHUS. (From Meios, glory, and 

 anthos, a flower. Nat. ord., I#gwminotM 

 Plants [Fabaceaj]. Linn., \l-Uiadel- 



phirt, 4-Dccandria. Allied to Sutherlan- 

 dia). The Parrot Beak plant and the 

 Glory Pea of New Zealand. Half-hardy 

 evergreen shrubs. Cuttings, in sandy 

 soil, under a glass, easily ; peat and 

 loam, with a little sand or charcoal. 

 Young plants are best grown rapidly, 

 old plants are so subject to red spider ; 

 do well in pots, planted out in a conser- 

 vatory, or against a wall where a little 

 protection can be given in winter.

 puni'ceus (crimson corolla). 3. Crimson. 



May. New Zealand. 1832. 



CLIDA'NTHUS. (From clidcios, delicate, 

 and anthos, a flower. Nat. ord., Ama- 

 rt/ttids [Amaryllidacere]. Linn., 6-Hcx- 

 andria, \-Monog t/nia. Allied to Pancra- 

 tium). This bulb increases so rapidly 

 by offsets, and splitting of the old bulb, 

 that it is difficult to keep bulbs of a size 

 to flower. It grows vigorously in a 

 border of fertile loam in front of a green- 

 house, in summer, but is so impatient of 

 wet that it requires to be taken up in 

 the autumn, without destroying the roots, 

 and kept dry till April in a pot of sand 

 or light soil. It looks like a yellow 

 Narcissus. 



C. fra' grans (fragrant). Yellow. Buenos 



Ayres. 1820. 



CLIMATE controls the growth of plants 

 most imperatively, and in the cultivation 

 of his fruits, flowers, and culinary vege- 

 tables, it forms the first object of the 

 gardener's inquiry. He must first know 

 the climate of which any given plant is 

 native ; and secondly, the soil which it 

 affects, before he can cultivate it suc- 

 cessfully How all-influential is climate 

 appears from the fact, that different 

 countries, though in the same degrees of 

 latitude, have often a totally different 

 Flora on soils similar in constitution. 



Now, the reason for these differences 

 is, that the countries thus contrasted differ 

 in climate that is, they differ in the in- 

 tensity and duration of the light and heat 

 they enjoy they differ in the contrast 

 of their day and night temperatures they 

 differ in the relative length of the day 

 and night they differ in the length of 

 their summer and winter, or, which is 

 synonymous, in the relative lengths of 

 their periods of vegetable activity and
