certainly not C. Cairnsiana, and that it docs not conform to 

 any published description of a Caladenia ; so that the orchid 

 which has been masquerading in Victoria for over thirty years 

 as C. Cairnsiana becomes C. coniifornm, and the former orchid 

 must be dropped from our records. It is purely a western 

 species. The specific name refers to the heart-shaped labellum, 

 and the common name proposed is " Heart-lipped Caladenia." 

 It may not be out of place to here briefly show some of the 

 main superficial differences between the two species : — 



Caladenia Cairnsiana. F. v. M. Cai.aukma cordifokmis, Rogers.

2. Sepals and petals narrow v Sepals and petals broad 

 linear, 5 lines long, not pro- linear, i inch long, produced to

 ively clavatc.

4. Labellum consisting chiefly 4. .\o \ein markings on the

Caladenia cardiochila, Tate. -.\n orchid was described by 

 Professor Tate in the Proceedings of llic Royal Society of South 

 Austrxilia in 1887 under the name of Caladenia cardiochila. 

 Tate's coloured drawing of this species was published in the 

 Proceeding's of the Royal Society of ]'ictoria in Professor 1*2 wart's 

 " Contribution to tlie Flora of Austraha," vol. xxiii. (i()i6). 

 This orchid was considered by some authoritie? to be too close 

 to C. Cairnsiana to be given specific rank, and the name was 

 subsequently dropped in favour of tlie Western species. 



Dr. Rogers has now decided tliat (\ Cairnsiana is jmrely a 

 Wf'stern plant, and tliat C. cardiochila must stand as a South 

 Australian species. We liav(; seen one Victorian specimen of 

 C. cardiochila from tlu- lierbarinm of \\. B. Williamson, 

 collected at (irantville by Wm. Wallace. As this orchid has 

 been collected at Border Town by Dr. Rogers, it is quite ])0ssible 

 that It will in the future be recorded from our Mallec district. 

 The vernacular name suggested is " Fleshy-lipped Caladenia." 

 The photo. -engraving wliich is " fig. i " (Caladenia Cairnsiana) 

 in Dr. Rogers's book on South .Australian orchids now becomes 

 C. cardiochila. The fl(rshincss of the labellum, as wcl! as tiie 

 vein markings, arc clearly shown in this engraving.
