Labellum not exceeding half length of 



lateral sepals ; lateral lobes entire, 



acute, falcate; middle lobe entirely 



covered with large crowded calli, 



arranged posteriorly in 2 obscure 



rows; leaf linear C. congesta, Br. 



Calli arranged in 4 rows. 



Lateral lobes of labellum ill-defined, the 



margins entire posteriorly, den- 

 ticulated or fringed anteriorly ; calli 



not reaching tip ; dorsal sepal gradu- 

 ally incurved; column gradually bent 



forward, striped with pink ; lateral 



sepals about 5 lines ; flowers generally 



reddish-brown, but sometimes white C. testacea, Br. 

 Lateral lobes of labellum broad, definite, 



obtuse, margins entire throughout ; 



dorsal sepal abruptly incurved at or 



below middle; column abruptly bent 



forward; lateral sepals about 8 lines; 



flowers whitish ... C. cucidlata, Fitz. 



Labellum hardly 3-lobed, contracting to 



a point for about two-thirds length, 



markedly denticulated for same 



length ; calli reaching to tip ; dorsal 



sepal gradually incurved ; lateral 



sepals about 9 lines; flowers white C. dimorpha, Fitz. 



Caladenia congesta is a larger species than C. testacea, 

 with larger flowers, the lateral sepals being about 9 lines as 

 compared with 5 lines in the latter plant. The pink flowers 

 of the former species are quite unlike the reddish-brown or 

 white colours of G. testacea.
