V. PHALAENOPSIS, Bchh. /.—An exceedingly interesting plant, and one 

 which is quite an exception to the other species, as it produces very showy 

 flowers. It is of climbing habit, producing long rooting leafless stems as 

 thick as one's little finger, terete fleshy and channelled on one side; the 

 flowers are large, 3 inches across, and borne in umbels at the ends of the 

 flowering branches, six or seven flowers being produced in an umbel, with a 

 few ovate deep green bracts below ; the sepals are ovate oblong acute, of a 

 faint blush white, keeled behind, the two lateral ones divided quite down to 

 the base on the lower side ; the petals are more ovate and less sharply pointed, 

 somewhat repand, of the same pale blush-white, and channelled down the 

 centre ; and the lip is folded in a broadly funnel-shaped form with an obliqfte 

 recurved repand obtuse limb, the outer side pale rosy blush, the inside tawny 

 orange, rather over 1 inch long, and f inch wide. It is exceedingly rare, but 

 well deserving of the attention of Orchid growers. — Madagascar.

V. PLANIFOLIA, Andr. — We have inserted this species, not on account of the 

 beauty of its flowers, which are inconspicuous and of a greenish shade of colour, 

 but because it is largely. cultivated for its fruits, which, when dried in the sun, 

 emit a most delicious perfume, and it is from this species, which is so largely 

 cultivated in tropical countries, that the vanilla of commerce is obtained. It is 

 of climbing habit, and may be beneficially used to cover the wall of a stove or 

 warm Orchid house. If it is desired to fruit this plant, the flowers will have to 

 be artificially fertilized. We have seen this plant produce quantities of seed- 

 pods annually in the collection of M. le Due de Massa, Franconville, France, 

 under the care of the gardener, Mr. Tallu6, and also at Osberton Hall, Worksop, 

 the seat of G. S. Foljambe, Esq., under the care of Mr. Woods. — West Indies.

V. WALKERIAE, Wight. — A curious leafless species, which produces very 

 handsome flowers, pure white inside ; the sepals tinged outside with fawn colour, 

 and a median streak of deep green ; petals also with a green median streak but 

 much narrower than that of the sepals, waved in outline and delicately trans- 

 parent, as is also the lip, which is obscurely three-lobed and slightly bearded 

 towards the base. It was named in honour of Mrs. Colonel Walker. — India.

(Tribe Vandeae, subtribe Cyrtopodieae.) 

 This is a small group of terrestrial Orchids, separated by Dr. Lindley 

 from the old genus Maxillaria. They are pseudobulbous, with few
