C. macrostylis, Fitz. 



Western Australia: Upper Kalgan River, Rogers, 

 21/9/19; Mount Barker district, Rogers, 23/9/19; Diamond 

 Tree School, near Jarnadup, Miss I. Knox-Peden, 

 December, 1919. 



This orchid chooses the most barren of ironstone country 

 on which to grow. On the Upper Kalgan a few specimens 

 occupied a small area of ground shunned by every other living 

 plant. At Mount Barker it was quite numerous amid scrub 

 almost equally inhospitable. 



It varies from a few inches to 8 inches in height, has 

 one or two flowers, and is a very hairy plant. The features 

 which chiefly attract notice are the short clavate points to all 

 the perianth segments, the broad yellow dilated bases of the 

 lateral sepals with their reddish central stripe, the dark 

 reddish-brown fleshy calli crowded along the central area of 

 the labellum, the dark purple glandular denticulations on the 

 margin of the apex. 



It is a very well defined species. 



C. hirta, Lindl. 

 Western Australia : the summit of the Porongorups and 

 many other places, Rogers, 24/9/19. Common. 



G. plicata, Fitz. 



Western Australia : Lake Chockerup, Dr. Syme Johnson, 

 Rogers, and others, 21/9/19; Tukurua, Miss Bryce Maclntyre, 

 28/9/11. 



This interesting species, with its short and extremely 

 club-pointed sepals, its crab-shaped fringed labellum, with the 

 dark central lobe tucked below like a crustacean tail, is quite 

 characteristic and cannot be mistaken for any other member 

 of its genus. It is localized in its distribution, but numerous 

 in certain localities. 



C. Drummondii, Benth. 



This species was carefully looked for, but was not seen, 

 nor has it ever been received from Western Australia. 

 Bentham gives the Swan River as its habitat. He says that 

 the chief characteristic is a leaf broader for its length than 

 in any other Caladenia. It is kjiown to science only from two 

 specimens in Hooker's Herbarium. 



C. Roei, Benth. 



Western Australia : Gnowangerup, Miss Bryce Maclntyre,
