16 FLOEA OF AUSTRALIA. 



carulea, C. alba, and O. carnea, and although in the present state 

 of our inquiries I think it may be prudent to regard them as dis- 

 tinct species, yet I should not be surprised, if hereafter they were to 

 be considered as varieties. Colour is certainly a very doubtful 

 note for distinguishing species, and yet the principal difference 

 between O. carnea and 0. ccerulea is that one is generally pink, 

 and the other blue ; whilst C. carnea is only separated from C. 

 alba by the vittate column and labellum, a mark of distinction 

 which does not always hold good, for sometimes individuals are 

 found with only the column vittate. 



(14.) Lyperantlms suaveolens is common in the spring, and is 

 one of our most interesting orchids. Dr. F. Mueller has furnish- 

 ed an accurate description of this species in his Fragmenta from 

 specimens sent from Parramatta. It does not appear that this 

 species has a wide range, for it is known to the Doctor only as 

 coming from Tasmania and the neighbourhood of Parramatta. 

 The specific name seems rather inappropriate, as the plant has 

 not any scent, or at all events that variety which is now referred 

 to L. suaveolens has not any. I have collected L. nic/ricans only 

 once in the neighbourhood, and it appears that although the 

 species extends very widely in extra-tropical Australia, it is 

 nowhere abundant. The plant in drying becomes perfectly black, 

 and indeed the other species here changes its colour in similar 

 circumstances, but not to the same extent. To Brown's L. 

 eUipticus, the Doctor adds L. Burnett ii from Tasmania, and L. 

 scrratus from Cape Leschenault. It is somewhat remarkable that 

 L. suaveolens, after passing over Victoria, should appear again in 

 Tasmania. 



(15.) Glossodia major and G-. minor are plentiful in this dis- 

 trict in the spring, and the former has a leaf which emits a de- 

 licious scent when bruised. Dr. F. Mueller had some idea of 

 uniting these two, but I believe that he has reconsidered the 

 matter, and now adopts Brown's view. G. major has a very 

 wide range, but the other species is more limited. 



(16.) Pterostylis according to Brown, has the following spe- 

 cies : P. concinna, P. opliioglossa, P. ctirta, P. acuminata, P. 

 pedunculata, P. cucullata, P. nana, P. nutans, P. obtusa, P. rejlcxa, 

 P.revoluta, P.yrandtflom, P.parviflorft, P. lonyifolia, P. squamata, 

 P. rufa, P, giblosa, P. mutica, and P. ditbia. Of these we have
