brous ; stigma orbicular, nearly lateral, umbonate at its

Polygone^e. 



Polygonum Linne. 



(Sect. Homalooladium.) 



Branches flat, almost leafless ; flowers axillary ; calyx five- 

 cleft ; stamens 7-8 ; styles 3 ; stipules minute. 



Polygonum patycladum. 



Perennial, glabrous ; stem erect, towards the base nearly 

 terete, near the branches compressed; branches quite 

 compressed, leaflike, articulated, streaked, nearly trans- 

 parent, either leafless or with a few oblong or hastate 

 lanceolate leaves, which are short stalked and acute at 

 the base ; bracts and stipule short, with fringeless margin ; 

 flowers solitary, or a few lateral; styles at the base 

 joined. 

 On moist places of New Caledonia. Shepherd.

 belonging to this genus. In habit it resembles some leafless 

 flat-branched Phyuanthi. 



Salsolacea 

 Blitum cristatum. 



Procumbent, somewhat downy and glandulous ; stems 

 imperfectly streaked ; leaves on long petioles, rhomboid 

 or oblong ovate, acute, at the base blunt, at the apex with 

 blunt teeth ; glomerules axillary, many-flowered ; fruit- 

 bearing calyx dry, closed, acuminate, with cristate wings ; 

 seeds smooth and shining, with a nearly acute margin. 



In the desert on the Murray, Darling and Lake Torrens. 



Allied to B. carinatum. 



Rhagodia nitrariacea. 



Shrubby, erect or diffuse ; branches spreading or reclined; 

 branchlets divaricate, grey, spinescent ; leaves alternate 

 fasciculate, oblong- or spathulate-linear, blunt, quite
