Sepals and petals brownish-red, with a yellowish or greenish 

 margin. Dorsal sepal erect, narrower than the lateral sepals, 

 which are flat, lanceolate, gradually pointed, and slightly clavate 

 at the tijD, with a minute glandular pubescence, and about half 

 an inch long. Petals narrower than the sepals, of about the same 

 length, tapering to a line point, without any glandular pubes- 

 cence. Labellum on a long claw, flat, crescent-shaped with a 

 broad triangular apical extension, marked with brown forked 

 veins diverging from the base; the anterior margins fringed with 

 narrow blunt denticles ; colour greenish-yellow, the middle lobe 

 dark-brown. Length, quarter inch ; breadth, three-eighths of an 

 inch. Calli on long stalks, clustered in the centre and at the base, 

 or obscurely four-rowed. Column much curved, broadly winged 

 in the upper two-thirds, nearly half inch long 



Caroona Hill, 45 miles due west of Port Augusta (Dr. W. L. 

 Chland, August, 1889). 



This species in its short petals and sepals resembles C. Cairn- 

 siana and C. reticulata., but differs especially by the shape of the 

 labellum. 



Caladenia tentaculata.* 



A slender nearly glabrous species from six to twelve inches 

 high ; one- or two-flowered. 



Sepals and petals pale-brown with a narrow dark-centre, taper- 

 ing into long filiform points, and densely beset with short reddish 

 glandular hairs ; from one and a half to two inches long. 



Labellum narrow, ovate-rhomboid, slightly contracted towards 

 the tip, sessile, without lobes, streaked with brown forked lines, 

 anterior margins shortly and bluntly serrate, about quarter of an 

 inch long and one-eighth in width. Calli in two rows extending 

 from the base to about half the length of the labellum, traceable 

 beyond as dai'k spots. Column very short, winged throughout, 

 slightly curved, under quarter of an inch long. 



Caroona Hill, 45 miles due west of Port Augusta (Dr. W. L. 

 Cleland, August, 1889). 



In general appearance this new species resembles C. filamen- 

 tosa ; but its labellmm is proper to the Section Phlebochilus, from 

 other species of which it is distinguished by its filiform sepals 

 and rhomboid labellum. 



In the following synopsis I have set out the leading characters 

 of the species of Section Phlebochilus ; of which two inhabit 

 south-west Australia — C. cliscoidea, Lindley, and C. midticlavia, 

 Reichenbach ; three South Australia, viz., C. reticulata, Fitz- 

 gerald, 0. tLxochila, Tate, and C. tentaculata, Tate ; and 

 C. Cairyisiana, F. v. M., is common to the tw^o regions.
