102 COOL ORCHID GROWING. 



material than is generally considered suflBcient for greenhouse 

 plants. 



0. AlexandrcB (Bateman, Bogota). — This superb member of 

 the genus is identical with the O. crispum of Lindley, but 

 will probably retain its present name in compliment to Eng- 

 land's future Queen. Sepals and petals from one to two inches 

 long, often an inch broad, of the purest white, rarely spotted 

 with rose ; lip white, with a blotch of lemon yellow on the 

 crest, and spotted with rose below. The flowers of this species 

 vary very much in form and colouring. It is one of the loveliest 

 of bridal Orchids, and a small spike of flowers, tastefully 

 arranged on a frond of Adiantum Farleyense or A. macro- 

 phyllum, forms a natural wreath or tiara that even Yenus 

 herself would be proud to wear. The plants may be removed 

 to the drawing-room or used for the decoration of the dinner 

 table, with impunity ; provided the temperature of the room 

 does not fall below 40°, no harm will be done. This plant is 

 also called 0. Bluntii. It flowers nearly all the year round 

 when grown in quantity, producing an abundance of flowers. 



0. Andersonianum, (New Granada), — This is like 0. crispum 

 in shape, or like a narrow-petaled form of that plant, of a creamy 

 white colour ; the lower halves of the sepals and petals are 

 streaked and spotted internally with reddish brown ; the lip is 

 also similarly marked, the upper part being yellow. 



0. aureo-ptirpureum (Rchb. fil., N. Granada). — -This is said to 

 be a noble plant, but I believe it has never flowered in this 

 country. It inhabits a very cold region, and is described as 

 bearing many-flowered spikes of golden yellow flowers spotted 

 and blotched with rich purple. It is sometimes, though 

 erroneously, referred to the well-known 0. luteo-purpureum. 



0. angustatum. — A pretty little species ; pseudo-bulbs two- 

 leaved ; panicles from one to two feet long. Flowers small, 

 from fifty to one hundred on a spike, about one inch across ;
