1275 mm. x 1 mm. wide (maximum) ; lateral petals, 12 mm. 

 X 15 mm. wide (maximum); labellum 105 mm. long x 

 85 mm. wide; column 9*5 mm. long. In this State (South 

 Australia) Tate's species C. cardiochila, which was reduced to 

 a synonym of G. Caimsia/riaj F. v. M., should now be 

 restored to specific rank. He gives the following measure- 

 ments for this species: — Lateral sepals 17 mm. x 45 mm. 

 wide, lanceolate; dorsal sepal narrower than lateral sepals; 

 lateral petals 17 mm. x 2 mm. wide. Labellum 10 mm. 

 long X 11 mm. wide (claw apparently not included). These 

 measurements show a wide departure from those of the type 

 specimen of C . Caimsiana. In cardiochila the lateral sepals 

 and petals are more or less spreading; there are no hairs on 

 the tips of the sepals. The anther has a short acute point 

 and there are two yellow oval glands at the base of the 

 column. 



(7. Caimsiana has not yet been collected in this State 

 (South Australia), nor as far as can be ascertained, in 

 Victoria.

This is apparently a rare and little known species, and 

 like C Caimsiana it is a plant of characteristic habit. The 

 only known drawing of it is to be found in Reichenbach's 

 Xenia II. t. 1S8, and this conveys a very imperfect impression. 

 Its peculiar appearance is due to the vertical position of the 

 labellum, the horizontal position of the curiously winged 

 column which is retracted at right angles to the ovary like 

 a serpent about to strike, and to the union of the dorsal sepal 

 and lateral petals (a very unusual feature in a Caladenia) to 

 form a hood. 



The following descriptive remarks are intended to supple- 

 ment those given in the ''Flora Australiensis" : — 



Segments of the perianth yellowish with red longitudinal 

 stripes, nearly equal in length, tapering to fine non-clavate 

 points. Lateral sepals lanceolate-falcate, the inflated portion 

 somewhat exceeding the point, divaricate, spreading, about 

 24 mm. long. Dorsal sepal retracted at base then incurved, 

 sharply falcate, with long fine rigid point, much narrower 

 than the lateral sepals, about 24 mm. long. Lateral petals 

 lanceolate-falcate, wider than dorsal sepal, but not quite so 

 wide as the lateral ones; lightly adherent to the margin of 

 the former from the stigmatic wing of column almost to their 

 tips, leaving a fenestrum on either side below the wings, thus
