■ O. PULCHELLUM DORMANIANUM, Williams.— T:h\a is the largest variety 

 of 0. pulchellum we have yet met with, being far superior to 0. pulchellum majus. 

 The pseudobulbs are much stronger and stouter than in the type and are rounder 

 in form ; the flowers, which are white, and 1^ to If inch in diameter, have the 

 sepals and petals fully J inch broad. It is named in compliment to C. Dorman, 

 Esq., Laurie Park, Sydenham. — Ouateinala. 



O. PULCHELLUM MAJUS, Bbrf.— This is a very robust form of 0. pulchellum, 

 having the pseudobulbs much larger ; the flowers are also nearly double the size 

 of those of the ordinary variety, and the racemes are stronger, with the blossoms 

 more numerous. In addition they are . very fragrant, so that one plant will 

 perfume the house in which it is growing. — OuatewMla. 



O. PURUM, JJc/t&. /. — ^A very pretty little species in the way of 0. Wallisii. 

 The flowers grow in spreading racemes, the sepals being of a light yellow with 

 the disk entirely covered with sepia-brown, the petals light yellow with a few 

 blotches of brown at the base, and the lip pure white, having a large purple 

 blotch about the centre. It flowers in the summer months. — New Grenada.

 the basilar portions of the petals lilac-purple; the lip is cordate, dilated and 

 undulated at the base, the front part lanceolate, acutely pointed, having a large

 received by u.s from New Grenada some years ago through Mr. C. Patin.' The
