628 PHANEROGAMIA. 



9. Haloragis filiformis, Sp. Nov. 



H. scabro-hirtella ; caulibus e basi ramosis strictis gracillimis ; foliis 

 filiformibus, inferioribus oppositis digitato-tri-quinqueseclis, superio- 

 ribus floralibusque alternis incequaliter trifidls vel integerrimis ; flori- 

 bus laxe sjiicatis monoids, masculis octandris, foemineis apetalis? 

 ovario subgloboso scabro. 



Hab. New South Wales ; in the vicinity of Hunter's River. 



Stems branched from the base, strict, very slender, terete, and ob- 

 scurely angled, from a span to near a foot high, very leafy, the 

 younger parts especially minutely scabrous -hispid. Leaves filiform, 

 scabrous-hispid like the stems ; the lower opposite, half or three-quarters 

 of an inch in length, including the undivided base or petiole, which 

 is rather shorter than the 3 to 5 digitate segments; the upper gra- 

 dually becoming smaller and alternate, and passing into bracts, 

 variously trifid, sometimes with the terminal lobe longer, or mostly 

 entire. Spike very slender, loosely flowered. Floicers barely a line 

 long, subsessile, monoecious: barren ones octandrous; the 4 petals oval, 

 complicate-carinate, minutely hispid on the back, barely twice the 

 length of the triangular-lanceolate lobes of the calyx; the stigmas 

 rudimentary : female flowers apparently apetalous, with 4 thick and 

 sessile hispid stigmas. Ovary subglobose, scabrous, even, four-celled. 

 Mature fruit not seen. 



This is abundantly distinct from any species known to me ; and 

 evidently is not the Goniocaipiis trifidus of Nees, which is dioecious 

 and tetrandrous, and with the lower leaves verticillate, &c.
