Flora of Australia. 237 



4. In his " Australian Orchids," Fitzgerald has greatly exagger- 

 ated the width of tin- mid-rib of the labellum of P. reflexa. 



5. /'. obtvsa, as determined by the Baron from the hills near 

 Pt. Elliot, Miss Hussey, No. 427, in 1895, is undoubtedly P. pedun- 

 culata. No specimen of this orchid has therefore been recorded from 

 the mainland of South Australia, vide Dr. Rogers, in " South Aus- 

 tralian Orchids." 



Restio ustulatus (F. Mueller, M.S.) 



Steins erect, terete, sometimes divided, 1 to 2 ft. high. Lower 

 sheathing scales closely imbricated, about 1 inch in length. The 

 upper ones longer — L 1 , ins., and looser. All acute and well sheath- 

 ing the stem. 



The floral bracts acute. That below the lower spikelets i in. in 

 length, while that below the terminal spikelet only \ in. in length. 



Spikelets in both sexes somewhat different. The male are more 

 conical, with very imbricate, appressed glumes. Those of the female 

 are broader, with larger glumes, and not nearly so appressed. 



Glumes in every rase are obtuse. 



Spikelets in both sexes few at the end of the stem, 1 to 3, sessile, 

 or nearly so within the bracts, or one within a lower bract on a long 

 pedicel that may extend to almost same length as terminal spike. 

 Spikelets oblong, conical, 1 in. long, of a dark brown, and very 

 closely resembling the solitary terminal spikelet of Ecdeiocolea, 

 monostachya; but the chief differences are: — 



1. Xo. of spikelets on each stem. 



2. Closeness of .sheathing scale to spikelet. 

 .'$. Length of sheathing scale. 



4. No. of sheathing scales. 



5. R. ustulatus more flattened, and redder spikelet. 



It also resembles in appearance the spikelets of Lepiconia among 

 the ( 'yperaceae. 



Glumes ovate, obtuse, very numerous, rigid, and closely imbricate. 

 The outer ones shorter and empty. Perianth in both sexes very 

 flat, about as long as the glumes, glabrous, or very hairy near the 

 tips. 



The three outer segments of the perianth hairy near the tips, the 

 three inner ones quite glabrous and hyaline. 



In the male flowers : Stamens .*}, filaments free. Anthers of two 

 distinct cells as seen in drawing. Attached to centre only. 



Female flowers : Ovary 2-celled, style 2, free and stigmatic. almost 

 from the base.
