Hab. : Cape Colony, South-eastern Eegion, district Kentani, in a 

 forest near Kentani, on trees, alt. 1,000-1,200 ft., Feb., Miss A. 

 Pegler, No. 993 ! 



Described from dried specimens and fresh flowers preserved in 

 formalin. In general appearance this most nearly resembles 

 M. caffrum mihi (see note above), but is well distinguished by its 

 smaller flowers, different sepals and petals, and more especially the 

 lip. I am indebted for this and many other good things to Miss 

 Pegler, who has made excellent collections in the neighbourhood of 

 Kentani, a district hitherto very little explored. To her we owe the 

 detection of Dermatobotrys Saundersii mihi (hitherto only known 

 from Natal) within this Colony, and the rediscovery of Stangeria 

 Katzeri, Begel, the native station of which was previously un- 

 known.
