(unextended) ; two large yellow glands at the base. Anther 

 incumbent, with a short point. Stigma large, circular, 

 concave, sticky, upper border produced into a short triangular 

 rostellum, situated just below the anther. 



This Caladenia approaches most closely to G. ovata^ 

 Rogers, but difiFers very materially as to the calli, which in 

 the latter species are small and mammillary, usually arranged 

 in two short rows, rarely in four, and occasionally quite 

 absent. In the new species they are well marked, flashy, 

 stalked, arranged usually in four rows, rarely in two. In 

 the former dark divergent lines are present on the labellum 

 and the points of the sepals are clavate; in the latter the 

 divergent lines are absent, and in all the specimens (about a 

 dozen) examined, there was no evidence of clubbing of the 

 sepal points. C . Cairnsiana, F. v. M., has an entire labellum, 

 but in this plant the calli appear to be always arranged in 

 two rows, the tip of the labellum has a dark-red narrow 

 callous margin, suggesting a ''binding" (this margin is very 

 constant and characteristic) ; dark purple divergent lines are 

 present on the lamina. There are no yellow glands at the base 

 of the column, but these are replaced by two horizontal rows 

 of small glandular hairs. The sepals and petals are equal in 

 length, and the former are only half the length of the same 

 segments in the new species, they are not produced into fine 

 points and the tips are consistently finely hairy; they are 

 always acutely reflexed against the ovary. In G . tesselata, 

 Fitz., the leaf is narrower, the perianth segments are not 

 produced into fine points; the labellum is not recurved, but 

 horizontal in its terminal half; the calli are not of the golf- 

 stick type near the base of the lamina, and although they 

 assume that shape elsewhere they are more fleshy than in 

 G . cordifornvis and are continued in four well-marked rows 

 to the extreme tip. 



In G . clavigera, Cunng., the labellum is not cordate in 

 shape, but gradually increases in width from the base to about 

 the middle, where it reaches its maximum diameter; there- 

 after it is recurved and triangular, the tip ending in a rather 

 long and sharp point. The sepals are usually clavate and 

 the column is only slightly incurved. The flowers are mucli 

 larger than in the new species and usually reach 3 inches 

 (7*5 cm.) in diameter. 



This orchid is not uncommon in Victoria, where it has 

 generally been accepted as Galadenia Gairnsiana, F. v. M.
