Caladenia cardiochila. 



A slender hairy species from six to nine inches high ; one-, 

 rarely two-fld. Leaf linear lanceolate, sheathing at the base, 

 from two to three inches long. 



Sepals and petals brownish-red with a yellow margin, or 

 yellowish with a brownish-red streak down the centre ; linear- 

 lanceolate, neither contracted nor clavate, and quite free of 

 glandular pubescence. Dorsal sepal erect, incurved over the 

 column ; narrower than the lateral sepals, which are flat, 

 lanceolate, dilated upwards, abruptly acuminate, and about 17 

 millimetres long by 4*5 broad. Petals linear, 17 millimetres 

 long by two broad. Labellum on a long claw, undivided, 

 margin entire, cordately ovate, somewhat flat, but not recurved, 

 contracted towards the tip where the margin is thickened, and 

 of a dark red-brown colour. The colour of the labellum is 

 yellowish above and below, with a reddish margin, and streaked 

 dichotomously on the upper side, and blotched on the wedge- 

 shaped tip with the same colour. Length, ten millimetres; 

 breadth, eleven mills. Calli in two rows, large, elevated, 

 closely packed, oblong, attenuated at the base and graduating 

 into linear-clavate at the base of the labellum, of a very dark 

 red-brown colour. The anterior third of the labellum is naked. 

 Column much curved, broadly winged in the upper two-thirds, 

 mottled with brownish-red. Anther with a short acute point. 

 Two oval calli at the base of the column. 



Sandy ground under the shade of Casuarinas and Eucalypts, 

 Golden Grove. Collected by various members of the Field 

 Naturalists' Club, October 2, 1886. Barabba Scrub, Hundred 

 Grace, S. Dixon (!), 1865. 



This species is conspicuous amongst congeners associated 

 with it by its broad labellum and short petals and sepals. The 

 accompanying species were C. dilatata, B. Brown, C. leptocliila, 

 Fitzgerald, C. carnea, B. Br., and O. latifolia, B. Brown. Prom 

 C. dilatata and its allies it is at once separable by its short 

 sepal points, in which respect it approaches C. Caimsiana, 

 P. v. M. Its nearest ally is C. tessellata, Fitzgerald,
