chocolate brown, edged with light yellow, the margins undu- 

 lated ; lip very singular in form, brown, with a yellow crest. 

 It should be potted in fibrous peat, and grown in the cool- 

 house. Native of Peru. 



O. unguiculatum. — A pretty winter-flowering species from 

 Guatemala ; the large yellow flowers are produced on a long 

 branching spike, three or four feet high, lasting a long time 

 in perfection. It succeeds best potted in good fibrous peat. 



0. varierjatum. — A pretty species from the West Indies ; it 

 grows six inches high, and has dark evergreen foliage ; spikes 

 branching and upright, bearing many blossoms of a rosy pink 

 colour, and continuing in beauty for several weeks ; it is best 

 grown on a block with plenty of moistm^e at the roots. 



0. ccanthodoii. — This plant belongs to the 0. serratum 

 section, and although the flowers are not so large as in that 

 species, they make a good display from their being so freely 

 produced. In growth it very much resembles 0. serratum ; 

 the flower spike is very long and trailing ; sepals and petals 

 rich dark brown, bordered with yellow ; lip brown, and yellow 

 in the centre. Native of Ecuador. 



Palumbina. 



P. Candida. — This plant, though nearly allied to Onci- 

 dium, is very distinct in habit and appearance. It has light 

 gi-een leaves and pseudobulbs, and produces upon its slender 

 erect spikes several flat waxy white flowers, which continue 

 in perfection a long time. It is from Guatemala, and thrives 

 best under rather cool treatment ; a rare and interesting 

 species. This will do in a pot, with peat, moss, and good 

 drainage, but it does not require much water at the roots at 

 any time.
