Phaius Wallichii is one of the stateliest of orchids, and 

 at the same time one of the largest- flowered. It has a 

 wide distribution in India, from the Nepal forests, in the 

 tropical region, eastwards in the lower Himalaya to Assam, 

 the Khasia Mountains and southward to Burma ; and it 

 occurs (as P. bicolor) in Ceylon, but has not hitherto been 

 found in the Madras Peninsula. The flowers vary greatly 

 in colour, from the chocolate-brown of the plan) here 

 figured to pale primrose-yellow, and the Bepals and petals 

 are sometimes concolorous on both surfaces, at others the 

 sepals are green on the back. The lip is less variable in 

 colour, having the tube yellow in the basal half, dull 

 reddish beyond it; the limb is white, with yellow or red 

 (or both) ridges on the disk. The limb of the lip varies 

 greatly in breadth, and is either truncate and apiculate or 

 acute or acuminate. I find no character whatever whereby 

 to distinguish the Cingalese P. bicolor, which is generally 

 described as having flowers yellow tinged with red ; but in 

 a drawing of it by Mrs. Walker, the colours are nearly 

 the same as those of P. Wallichii, as they are in the figure 

 in this work (Plate 4078), except that the backs of the sepals
