870 LIST OF THE ORCHIDE^E OP THE MUDGEE DISTRICT, 



22. Prasophyllum rufum, R. Br. 



Hare. On flats and creek-banks. Flowers in May and June. 



23. Microtis porrifolia, Spreng. 

 Flowers in October and on into December. 



24. Microtis parviflora, R. Br. 

 Flowers about the same time as its congener. 



25. CORYSANTHES 11. Sp. 



This plant I have discovered only this year. So far as I know 

 it is a very local plant, only growing in one gully of the 

 Beaudesert Hills. It must be a shy bloomer, as I have searched the 

 same place every year since 1878, and this is the first time I 

 have seen it. It is at present in Mr. Fitzgerald's hands for 

 description. It comes nearest to C. pruinosa. Flowers in July 

 and August. 



26. Pterostylis concinna, R. Br. 



Generally distributed in moist gullies. Flowers from June to 

 September. 



27. Pterostylis striata, R.D.F. 



Rare. I know only one place in the Beaudesert Hills where this 

 plant grows. Flowers in July. 



28. Pterostylis curta, R. Br. 



Common in shady corners among the hills and rocks. Flowers 

 from July to October. 



29. Pterostylis acuminata, R. Br. 

 Collected by Dr. Woolls.
