7. Chiloglottis Muelleri, Fitz. 



This very rare orchid, which was discovered by Mr. C. 

 French, sen., on the Lodden •River, Victoria, and described 

 by the late R. D. Fitzgerald many years ago, seems to have 

 been lost sight of since that period. 



Recently I have received it from three localities, viz., 

 Fern Tree Gully, Healesville, and Ben Cairn, near Warburton. 



The specimens were collected between October 27 and 

 December 3, 1917, and I am indebted for them to Mr. E. E. 

 Pescott, of Melbourne. 



Strangely enough, it has never received recognition in 

 Victoria, and does not appear on the listed plants of that 

 State. It was merged by Baron von Mueller into C. Gunnii, 

 Lindl., from which, however, it differs in several important 

 respects. 



These differences may be shown as follows : — 



C. Muelleri. C. Gunnii. 



Rather slender. Rather stout. 



Relatively long and Relatively short and 



narrow; elliptical- broad; oblong-lanceo- 



lanceolate or oblong- late or ovate. 



lanceolate. 

 Narrow; quite green. Broad; reddish-brown. 

 Ovate-lanceolate; green. Broadly ovate; reddish- 

 brown. 

 Dark bottle-green or Reddish-brown; a large, 



brown; generally ses- long-stalked, clavate 



sile but occasionally 



very shortly stalked ; 



mostly large with 



rounded or elongated 



contours ; often cres- 



centic, reniform or 



sausage-shaped ; irre- 

 gularly grouped in 



centre and at base of 



lamina. 

 Spreading.

callus at base of

All my specimens were found growing on the trunks of 

 tree-ferns (Dicksonia). This habit appears to be shared in a
