Thelymitra bpipactoides, F. v. M. in Fragm. Vol. V., 174 (1866). 

 *' Stout Hood-Orchid." (Orchidaceae). 



The Kew Index gives this plant as a synonym iov T . canali- 

 culdta, R. Br. Bentham suggested that it might be a broad- 

 leaved form of T. irioides; or 7\ raiialiridata. The latter 

 appears itself to be a slender variety of T. irioides, whereas T. 

 epipacf aides is stouter, has larger flowers and has the middle 

 lobe of the labellum more in one piece (Fig. 7 shows an extreme 

 case of lobing). Its affinities are more with T. arisfafa than 

 with T. epi'pdctoides. 



The species is given in Mueller s Second Census of Australian 

 Plants as Victorian only, but Dr. Rogers has since recorded it 

 in Trans, of the Roy. Soc. of S.A., Vol. XXXIII., p. 262 (1909), 

 from South Australia.
