Some hitherto unknown Australian Plants. 41 



late bracteoles. Laminae of petals lh line long, exserted; 

 claws biauriculate. Tube of filaments enclosed. Anthers 

 kidney-shaped. The fruit has not been found. 



HaLORAGEjE. 



MyHophyllum dicoccum. 



Lower leaves pinnate, with capillary opposite or alternate 

 segments ; upper leaves alternate, linear or lanceolate, 

 entire, toothed or pectinate ; flowers axillary, sessile ; 

 fruit consisting of two carpels, which are glabrous, trun- 

 cate, round at their back and hardly tubercled. 



In lakes, rivers, and lagoons towards the Gulf of Carpen- 

 taria. 



The habit of the plant is that of certain forms of M. 

 variifolium. Flowers at least in part hermaphrodite. Stigmas 

 purple, long bearded. Stamens seemingly 4. Fruits solitary, 

 about § of a line long, slightly tapering upwards, rounded at 

 the base, in exceptional cases augmented to 3 or even 4 

 carpels. 



P0RTULACE.E. 



Calandrinia uniflora. 



Annual, glabrous ; stemless, or with an erect naked stem, 

 producing a bunch of leaves at the apex j leaves longer 

 than the stem, terete, acute, glaucescent, without any 

 furrow; peduncles terminal, thin-filiform, thickened at 

 the apex, one-flowered, twice or thrice longer than the 

 leaves, with 2 or 3 cordate-lanceolate acuminate remote 

 deciduous bracts; petals 8-11, lanceolate, almost three 

 times longer than the orbicular- cordate sepals ; stamens 

 numerous ; style none ; stigmas 3-6 ; capsule as far as 

 the middle four-valved. 



On arid plains and ridges on the Victoria River. 



Root pale, descendent, simple, with few fibres. Stem often 

 red, \-\\ inch long, at times undeveloped. Leaves and 

 peduncles united, as the case may be, in a radical or terminal 

 fascicle ; the former 4 inches or less long, hardly thicker than 

 one line. Peduncles erect, or adscendent, smooth, producing 

 the bracts chiefly in their lower part. The latter hyalinous, 

 clasping, very tender membraneous, scarcely one line long. 

 Sepals measuring two lines, rather acute, dropping in age.
