op This is, without doubt, one of the most handsome and remarkable species in 
the whole genus. It was discovered by Mr. Griffith, many years ago, on the 
Khasya Hills, growing in great abundance upon trees of Gordonia, in the pine and 
oak forests of that region, the numerous spikes of lavender-blue flowers producing 
a charming effect. Sir Joseph (then Dr.) Hooker also found this species in the 
Jaintea Hills at 3,000 to 4,000 feet elevation, growing upon small trees, in exposed 
situations, the roots sprawling over the rough bark; at the time this plant flowers, 
he says, the temperature ranges between 60° and 80°, and in. winter hoar-frost 
forms on the ground. In Upper Assam this species grows at some 5,000 feet 
altitude, where there are often six or eight degrees of frost during the month of 
December; there it rapidly increases in size and flowers profusely. The eg 
appear very soon after the rainy season is over, which is about the end o 
September or beginning of October, and they remain in full beauty for oe 
siderable time. The plant was first introduced to this country in a living state 
by the Messrs. J. Veitch & Sons, of Chelsea, through their collector, Thomas Lobb. 
We well remember how enchanted we were with this Vanda, when the first plant 
was exhibited in the rooms of the Royal Horticultural Society in Regent ; Street,
