45. Lyperanthus suaveolens, R. Br. 



(Caladenia suaveolens in the Flora Australiensis). 



It has been objected to the specific name that the plant is 

 not at all sweet-scented, but I have repeatedly noticed that it has 

 a very rich scent when exposed to hot sun. It is very local 

 Flowers from September to November. 



46. Eriochilus autumnalis, R. Br. 



Common every where. Flowers from March to May. In experiment- 

 ing on this plant I have repeatedly noticed a viscidity of the pollinia, 

 so that when it is attempted to withdraw them from the anthers 

 a piece sometimes draws out into a glutinous thread, which on being 

 stretched flies back, and carries with it a piece of the pollen. This 

 sometimes strikes the stigma and adheres. In this way the 

 plant is possibly often fertilised by its own pollen with the help of 

 insects. 



47. Caladenia clavigera, A. Cunn. 



Rather rare. Flowers in September and October. 



4b. Caladenia dilatata, R. Br. 

 Common. Flowers from September to November. 



49. Caladenia arenaria, R. D. F. 

 Rare. Flowers in October and November. 



50. Caladenia filamentosa, R. Br. 

 Common on stony hill-sides. Flowers in August and September.
