Chestertoni and Brassavola Digbyana. In both these the labellum is 

 fixed. Chondrorhyncha Chestertoni may be taken as a type. It is a 

 beautiful species, described by Reichenbach in the " Gardeners' Chronicle " 

 in 1879. The flowers are pale yellow, and very delicate in structure. It is 

 said to come from New Grenada. Further, we have in the well-known 

 Bulbophyllum barbigerum an instance of an orchid in which the labellum 

 is not only fringed or covered with hairs, but in which this organ is 

 delicately hinged, and moves with the least current of air. This orchid, a 

 native of Sierra Leone, has been in our collections for about three-quarters 

 of a century, and can, therefore, not be called " uncommon." There are, 

 however, two more recent introductions which are still uncommon.

Bulbophyllum trcmulum. — I got the Glasnevin plant from Mr. O'Brien, 

 who imported it from the Mysore Hills, and I regard it as one of the most 

 striking orchids when in flower. The peculiar heavy fringe of dark hairs 

 gives an irresistibly comical appearance to the flowers when looked at 

 from a certain angle. 



Bulbophyllum miniatum (fig. 53) comes from the Congo. It flowered 

 at Glasnevin in August 1903. Here the hairs are white, and instead of 

 being a fringe only they form more or less a beard all over the lip. This 

 organ is extremely vibratile, so much so that when the photograph from 

 which this slide was prepared was being taken the chimney had to be 

 stuffed with paper, as the draught from it kept the flowers constantly
