With the habit of W. Bmchii, this fine species is quite distinct, the 

 calyptra being nearly bare, and the marginal band of long narrow cells a

 are always more or less evident ; Mr. Stewart's specimen bears scattered 

 oblong gemma; on the leaves. The species was first discovered by Mr. 

 Johnson in Madeira,
