thirty expanded flowers at the same time. It is the finest 

 form of the small group, of which 0. Insleayi and 0. Schlie- 

 perianum are the other species. It is very easily cultivated, 

 and does best, like Citrosmum and Krameri, in the warm end 

 of the house. 



a. *0. grande superbum. A selected garden variety, .with 

 fine, richly -blotched flowers. 



0. Hallii. See 0. luteo purpureum. 



0. hastilabium. This is a strong-growing species, with 

 thick, pale green, fluted pseudo-bulbs, and tall, branched 

 flower-spikes, erect and glaucous ; flowers from fifty to one 

 hundred on a spike, from two to three inches across ; sepals 

 and petals lanceolate, incurved, pale green, barred with purple 

 or brown ; lip purple at the base, white at its apex ; the flowers 

 open gradually in succession for many weeks. Blooms about 

 May to July, lasting three months. 



0. liystrix. See 0. luteo purpureum. 



*0. Insleayi (Mexico, 1840). A species closely resembling 

 grande in habit, but its pseudo-bulbs are more compressed, 

 longer, and fluted ; flower-spikes from five to ten flowered ; 

 sepals and petals pale green or yellow, barred heavily with

 brilliant golden yellow, spotted with crimson. Flowers in

*0. Krameri (Costa Rica). A very pretty little species, 

 related to 0. pendulum. Its pseudo-bulbs are flat, one-leaved; 

 flower-spikes from two to three flowered ; flowers rather 

 smaller than those of 0. citrosmum (pendulum), and more 

 delicately tinted ; sepals and petals oblong, white, suffused 

 with flesh-colour ; lip reniform, of a soft flesh-colour, having a
