68 AUSTRALIAN PLANTS. 



twigs and the tube of the calyx hirtcUous ; bracteolcs shorter than the 

 pentagonal tube of the calyx, connate to the middle and apiculate by 

 the excurring carina. 



Hab. In rocky, arid declivities of the Grampians, the Serra, and 

 Victoria ranges. 



Var. p, glabra; dwarf 3 leaves almost smooth. 



Hab. On the subalpine summit of Mount William. 



I do not hesitate to refer to this species Ge^tetliyllis alpestris of 

 Lindley (in Mitchell, Three Expeditions, vol. ii. p. 178), described 

 from specimens collected by Sir Thomas Mitchell on Mount William. 

 These specimens, transmitted to Professor Lindley, were probably not 

 well developed, being gathered in the month of June. Examining the 

 plant last year in the month of November, I became convinced that it 

 belongs to the genus Lhotzhja. I have not retained the specific name 

 alpestris, as the plant occurs most abundantly on the lower parts of 

 those mountains, and in localities much exposed to the hot north- 

 westerly winds. 



XIX. CUCUREITACE^. 



82. Cucurbita micrantJia, F. Muell. ; stems prostrate, angulose, 

 simple, as well as the petioles strigosely asperous ; leaves subcordate, 

 with five short, blunt, dentato-sinuate or incised lobes, on both sides 

 hirtello-asperous, on the mar^'in and beneath along the nerves densely 

 strigulose ; tendrils short, undivided ; peduncles axillary, filiform, fas- 

 ciculate, much shorter than the petiole, with the calyx pubescent; 

 flowers monoecious ; berries globose, even, smooth, many-seeded. 



Hab. On the sandy-loamy banks of the Murray, sometimes washed 

 by the floods. 



The fruit might, on account of its intense bitterness, perhaps be 



substituted for Colocynth. 



XX. POETULACEJE. 



•J* 



83. MoUugo Novee-HoUandice, F. Muell. j stems numerous, pros- 

 trate, dichotomous ; leaves pseudo-verticillate, unequal, spathulate- 

 lanceolate, at the top indistinctly serrulate, finally glabrescent, young 

 ones together with the branches woolly-pubescent ; flowers triandrous, 

 pseudo-verticillate ; sepals blunt, a little longer than the ovate capsule 

 and about equal in length to the pedicel ; seeds reniform-ovate, shi- 

 ning-brown, densely seriato-granulate.
