T. Kirk. — On Netu Cyperaceons Plants. 261 



revision of the CyperacecB, kindly examined my specimens of 

 this curious little plant, for which he suggests the name here 

 adopted. In his letter he states, "This belongs to my sub- 

 genus Eleogenus. In the absence of setaB, and in the very 

 small style-base, it approximates to -some of the New Zealand 

 species of Scirpus.'' 



I need only add that small specimens of E. acuta, E. Br., 

 approach this species very closely in general appearance, but 

 may easily be distinguished by the truncate mouth of the 

 sheath with its foliaceous mucro, the presence of bristles, and 

 the trigonous nut. 



Gahnia robusta, n. s. 



A robust species, with erect culms, 6ft. -7ft. high, as thick 

 as the little finger. Leaves 5ft. -6ft. long, more or less invo- 

 lute, excessively scabrous, produced into long filiform pendu- 

 lous points. Panicle 2ft. -3ft. long, dense, striate, narrow, 

 erect ; lower branches 5in.-10in. long ; stem-leaves narrow 

 with long filiform points. Spikelets narrow-lanceolate ; outer 

 bract lanceolate-acuminate; strongly 3-nerved ; empty glumes 

 4, coriaceous, with a strong nerve. Outer flowering-glume 

 closely enwrapping the flowers, broadly ovate, obtuse, faintly 

 nerved ; inner flowering-glumes similar, but more membranous ; 

 lowest flower male, stamens 6, filaments united at the base, 

 flattened, flexuous and elongating ; upper flower hermaphro- 

 dite, stamens 5, ovary fusiform, style-arms 2. Nut ovoid, 

 black or brownish - black, shinmg, transversely furrowed 

 within. 



Hah. North Island: Mungaroa, Wellington. T. K. 



This species has the strict habit of G. rigida, T. Kii-k, but is 

 more robust. Its affinities are with G. setifolia, Hook, f., 

 and G. xantliocarpa, Hook. f. : it differs from both in the 

 erect culms, the strict panicle, and the number of style-arms ; 

 it is more robust than the former, from which it differs essen- 

 tially in the larger black ovoid nut. From G. xanthocarpa it 

 differs also in the nut being smaller, shorter, and broader. 



Carex dallii, n. s. 



A small, slender, tufted species. Culms about 6in. high. 

 Ijeaves shorter than the culms, J^in.-J^in. broad, involute. 

 Spikelets 3-5, distant, fin.-fin. long, narrow, the lowest basal 

 on a long slender peduncle, the uppermost female, sessile, 

 with a few male flowers at base, rarely at apex. Glumes 

 membranous, ovate - acuminate, the lower shortly awned. 

 Style-arms 3. Utricles (immature) ovate-fusiform, shortly 

 bifid. Bracts overtopping the culms. Male spikelet longer 

 than the female.
