rightly states that the ripe capsule dehisces by four valves; but in ail 

 the capsules I examined, there were certainly only two styles, so that 

 although the plant cannot be referred to Alsine as generally defined, 

 there might be some justification for referring it to Arenaria in its 

 more restricted sensé. I know of no species of Arenaria with either 

 four sepals or two stamens : and though Alsine aretioides has tetra- 

 merous fiowers and 8 stamens, otherwise it is a typical Alsine. The 

 styles, as far as I was able to examine them, seemed to alternate with 

 the stamens. The plant while allied in essential characters with Are- 

 naria and Buffonia has the habit of a species of Sagina. 



ICONIS EXPLICATIO 



a. Flos pedicellatus. 



b. Ovarium lonaitrorsum sectum. 



The name of Littledalea first suggested itself to me as the name of 

 the proposed genus, in honour of the distinguished explorer, but I find 

 that Mr. Hemsley further on in his paper has utilized the name for a 

 new genus of grasses. I hâve therefore resorted to the convenient device 

 of forming the name from the locality where the plant was found, which 

 in a comparatively unexplored conntry precludes the possibility of its 

 having been used before.
