P. AUSTRALE, Br. In this species, as in P. elatum, the 

 lateral sepals are very consistently connate. A departure from 

 this rule is noted in the case of certain specimens collected 

 by Messrs. E. E. Pescott and C. French, jun., at Monomeith, 

 Victoria, among which there are a number of flowers with 

 five sepals. 



P. BREViLABRE, Hook. f. Victoria: Mount St. Bernard 

 (4,000 ft.) and Mount Hotham (5,000 ft.), Australian Alps; 

 Mr. A. J. Tadgell. December, 1913. 



Pterostylis PYRAMiDALis, Liudl. Westem Australia: 

 Jarnadup ; Miss Knox-Peden. 1/9/21. 



All of these specimens are unusually tall, some attaining 

 a height of 33 cm. ; the plant quite slender and erect. Leaves 

 at the base 3 or 4, ovate, acute, not strictly rosulate, shortly 

 petiolate or clasping; passing into leaf -like sessile alternate 

 bracts, ovate to lanceolate in shape, diminishing from, below 

 upwards, the lower ones generally with serrulate or crenulate 

 margins, sometimes 16 in number. Flower much larger than 

 that of P. nana; the galea from base to crest often nearly 

 2 cm. long. Tlie inturned tooth between the lobes of the 

 lower lip appears to be invariably present, but in other 

 respects the general habit of the plant is very different from 

 that of P. nana. 



P. CYCNOCEPHAi.A, Fitzg. N cw SoutJh Wales: Mount 

 Kosciusko (7,300 ft.); Dr. Green. 29/12/21. 



P. PEDOGLOSSA, Fitzg. Tasmania : Brown Mountain, 

 Port Arthur; Miss A. L. Rogers. 2/5/19. 



P. MiTCHELLi, Lindl. South Australia: Mount Pata- 

 warta (3,060 ft., 355 miles north of Adelaide); Mrs. B. S. 

 Rogers. 14/10/15. 



P. RUFA, Br. South Australia: Mount Patawarta 

 (3,060 ft., 355 miles north of Adelaide); Mr. B. B. Beck. 



5/10/20. 



Labellum on a very wide and elastically membranous claw, 

 longer and narrower than usual, very hairy, the hairs of 

 exceptional length. 



CoRYSANTHES, sp. ( ? ) Capsulcs deliisciug, on slender 

 pedicels, 13-15 cm. long. The remains of the flower enabled 

 me to identify the genus but not the species. The plants 

 were sent from a Victorian locality, and are of interest in 

 showing how the pedicel, which is almost sessile during the 

 flowering season, becomes enormously elongated in order that 

 the seed capsule- may receive the benefit of wind and sun in 

 the process of maturation. Corysanthes blooms in June or
