This little plant varies much in size and in the form &c. of the lip ; 
some of my specimens from Tasmannia are scarcely 23 inches high, 
others from the south coast of N. Holland are nearly a foot high, with the 
flowers large in proportion, and the bands of the lip and column nearly 
obsolete. In this latter too I find a second line of glands imperfectly 
formed upon the lip. The form of the lip is also far from constant. In 
Mr. Gunn's no. 606. the middle lobe is only serrated and much longer 
than the lateral ones; in his no. 912 the same part is deeply cut at the 
edge, and so little longer than the side ones as to give the lip almost a 
cuneate figure.

C. perianthii foliolis acutis, labello vittato ; glandulis biseriatis, lobi in- 
termedii marginibus integerrimis : disco glanduloso, bracteà scapi ad-

adily known from the two preceeding by its shor 
spreading hairy leaves, ind the entire middle lobe of the labellum. Other- 
wise it is much like them. I have seen no certain specimen, except 
that distributed among Sieber’s plants no. 163.
