The Culture of Greenhouse Orchids 



spike is well started ; but it must not be allowed 

 to shriyel. Water once a month is a good general 

 rule. If too much wetted at this time, it will not

 growth when an inch or two inches high. It must 

 be looked for ; the plant wants abundance of water 

 then. In these respects citrosmum is exceptional ; 

 also it loves the sun, asking only a slight shade. 

 March to May. Mexico. 1840. Zs. Qd. 



i'oradinci (Mr. Coradine, a collector). — A natural 

 hybrid of crispum x Lindlcyanurn. Grraceful, and 

 comparatively cheap of late. Pale primrose, blotched 

 with chestnut. January and February. New 

 Granada. 1872. lO-s. Qd.

Coronarium (crowned). — A large climbing species, 

 peculiar in growth and bloom, copper colour, edged 

 with yellow, and yellow lip. One of the stateliest 

 Odontoglots. The pair of giants in Baron Schroder's 

 collection, the noble plant of Mr. E. H. Measures, 

 bearing eight flower-spikes this spring, are not to 

 be forgotten by those who see them. It has the 

 reputation of " doing badly," because, I think, im- 

 ported specimens are rarely in good condition. If
