 keep the leaves of a 1 ' healthy colour, liquid manure 

 must be given when the pots are full of roots.

CALANDRINIA. 



A genus (ord. Portulaceje) 

 comprising a large number of 

 species of half-hardy, annual, 

 biennial, or perennial herba- 

 ceous plants, distinguished by 

 succulent stems and leaves, and 

 in many cases large, showy, red 

 or purple flowers. The greater 

 number of species belong to 

 America, the remainder to Aus- 

 tralia. The few species in cul- 

 tivation are treated as annuals 

 or biennials. Propagation is 

 effected by means of seeds 

 sown in well drained pots of 

 sandy soil in early spring, the 

 pots being stood in a warm 

 greenhouse. When the seed- 

 lings are large enough to handle 

 they should be thinned to five 

 in each pot, potting all on 

 together when necessary. By 

 this means better plants may 

 often be grown than when 

 pricking off is done in the 

 ordinary way. At all times 

 plenty of sunlight is essential. 

 About the end of May they 

 may be transferred to a sunny 

 border or rockery out of doors. 

 Seeds may also be sown in open 

 borders about the end of April. 

 Plants grown in the latter 

 manner flower as the earlier 

 ones stop.

CALANTHE. 



Description. Handsome terrestrial Orchids (ord. 

 Orchidacese), found in the Malay Peninsula, 

 Borneo, Japan, and other countries. The species 

 are evergreen or deciduous, and characterised by 

 large, broad, many-ribbed or plaited leaves ; thick, 



fleshy pseudo-bulbs ; and long- spikes of showy 

 flowers, distinguished by the lip being attached to 

 the column, and by eight thick, waxy pollen 

 masses adhering to a separate gland. The flowers 

 last for several weeks, either on the plant, or cut 

 and placed in water. In most places they are 

 considered to be amongst the easiest of Orchids 

 to grow. 



Propagation may be effected by division of the 

 pseudo-bulbs, or by cutting them in pieces and 

 placing them in sand, severing the sucker-like 

 shoots as they appear, and treating them as cuttings. 



Soil. A compost of turfy loam, leaf mould, and 

 sphagnum, with an addition of silver sand and dry

cow manure, suits them admirably. The drainage 

 must be good, as during the growing season 

 abundant supplies of fresh water are necessary ; 

 the evergreen section require plenty of water in 

 winter as well. 



Other Cultural Points. Repotting should be 

 done in February and March, the bulbs being 

 placed singly or several together in 5", 6", or 7" 

 pots. The bulbs should be placed on the top of 

 the soil, taking care not to bury the young shoots 

 which are pushing from the base. No water will
