218 orchid-grower's manual. 



It produces its spikes of flowers in June, July, and August, 

 the colour being purple, green, and white. It continues 

 blooming for two months, if kept in a cool-house. This is a 

 useful plant for exhibition, on account of its continuing in 

 bloom so long. 



0. Insleayi. — This gi'ows in the same way as 0. grande : 

 the flowers are brown, yellow, and orange, and are produced 

 on a short spike at difierent times of the year, lasting in 

 beauty three weeks. Native of Mexico. 



0. Insleayi splendens. — In this variety the sepals and petals are 

 rich shining brown tipped with yellow ; the lip is large, yellow and 

 spotted with purple. A very fine form introduced from Mexico. 



0. Krameri. — This is a rather pretty species, and seems to 

 be related to 0. citrosmum, though having a very difierent 

 appearance. The pseudobulbs are somewhat flat, with sharp 

 edges, in some specimens almost spherical, in others ovate, 

 and pale green in colour, bearing, as far as I am aware, a 

 single leaf only. The spikes are freely produced from the 

 base of the bulbs, and are pendulous, bearing several flowers 

 a little less than those of 0, citrosmum ; the sepals and petals 

 are strap-shaped and obtuse ; the lip somewhat reniform, and 

 deeply notched in front. The whole flower is of a charming 

 violet colour, the lip, in addition, being marked and spotted 

 with yellow and purple, with two lines of rich dark brown near 

 the column. It is a good addition to this numerous family, and 

 should be grown in peat and sphagnum moss, and will, like 

 0. citrosmum, require a little more warmth than the generality 

 of the genus. Native of Costa Rica. 



0. IcBve. — A pretty species, which will take the very coolest 

 treatment. It is very nearly allied to 0. Beichenheimii, and 

 may probably prove to be a variety of that species. Being a 

 very abundant bloomer, it will no doubt become generally 

 cultivated.
