Lateral sepals spreading as iu C. caniea, falcate- 

 lanceolate, 11-13 mm. long; upper-surface a deep red (almost 

 claret-colour), sometimes passing into a greenish-gold at the 

 tips; lower-surface dull gold, iridescent, studded with dark- 

 reddish glands. Dorsal sepal erect but much incurved, about 

 10 mm. long, contracted towards the base, spathulo- 

 lanceolate, rather wider than lateral sepals, its dorsal surface 

 glandular and similar in colour to the lower surface of the 

 lateral sepals. Lateral petals narrower than the other 

 segments, about same length as the dorsal sepal, coloured as 

 in the case of the lateral sepals. 



Labellum ovate on a short claw, about 5 mm. long; 

 lateral lobes definite, erect, rather, acute with entire margins 

 and transverse red stripes, anteriorly merging into 2 or 3 

 blunt or clavate teeth; the middle lobe rather broadly 

 triangular, recurved, dark purple and very glandular, with 

 long clavate glandular calli on its margins; lamina between 

 the lateral lobes entirely covered with ratter crowded wide- 

 headed short pedicelled dark-purple calli arranged in four 

 rows, the calli becoming sessile without definite arrangement 

 on the tip of the middle lobe and extending to the extreme 

 apex. Column about 6 mm. long, much incurved in its upper 

 part, wings wide and splotched with red, its dorsum marked 

 with intermittent red lines. Anther pointed, incumbent; 

 pollen-masses in two lamellated somewhat triangular pairs 

 easily removed on a needle, no caudicular or other connection 

 with the rost-ellum. Stigma situated immediately below the 

 anther, fleshy, concave, semicircular in its lower border, the 

 upper border passing into a sticky triangular rostellum.

The unusual and beautiful colouring of this orchid gives 

 it at first a very distinctive appearance, but a careful analysis 

 shows that it has close morphological affinities with Caladenia 

 congesta, Br., and C. te'^tacea, Br. C congesta has, 

 however, very much larger flowers which are almost always 

 multiple; the labellum has a very long narrow middle lobe, 

 without any marginal appendages but completely covered 

 with densely-packed fleshy flat-topped calli, arranged trans- 

 versely so as to give to this lobe a som.ewhat terete corded 

 appearance; on the lamina behind these, the calli are still as 

 densely packed, they are all sessile with the exception of the 

 pair next to the claw, they are very fleshy and flat-topped. 

 and are arranged longitudinally in two rather, obscure rows; 

 the labellum is nearly twice as long as that of the new species. 

 In C. testacea the lateral lobes of the labellum are 

 usually ill defined and sometimes practically obsolete ; the calli
