Cakyophylleae. 

 9. Colohanthus pulvinatus. 



Perennial, glabrous; stems numerous, moos-like tufted; 

 leaves densely crowded, rigid, squarrose, broad-subulate, 

 channelled triquetrous, pungent, shining, with a shghtly m- 

 flexed mucro ; sheats close; flowers terminal, sohtary, on very 

 short and thick peduncles, pentamerous ; sepals from a broad 

 base lanceolate-subulate, hardly longer than the egg-shaped 

 capsule, and nearly twice as long as the stamens. 



On the highest, barest, and gravelly tops of the Munyang 

 Mountains. (6,000^6,500 feet.) 



This forms a near approach to C. Benthamianus, a native 

 of Cape Horn and the Falkland Islands, and not yet found 

 similarly presented either in New Zealand or Tasmania, but 

 is apparently identical with the pentamerous form of C. Ben- 

 thamianus from Campbell's Island. Since also my plant m- 

 variably shows a quinery division of the flowers, I ha^e 

 separated it from the South American one, foUowmg Dr. 

 Hooker's suggestions in the Flor. Antarct., p. 247. 



Stackhouseae. 

 10. Stackhousia pulvinaris. 



Depressed, with numerous intricate rooting branches, 

 perfectly smooth ; leaves somewhat fleshy, oblong or spathu- 

 late-linear, nearly blunt ; flowers solitary on the summit of 

 very short branchlets; bracteoles twin, as long or longer 

 than the pedicel ; flowers yellow ; three of the stamens longer 

 than the two others ; anthers glabrous ; style deeply bi- or 



On the highest summits of the Australian Alps, where satu- 

 rated with moisture, the widely expanded tufts decorated with 

 fragrant starry flowers, form a beautiful carpet. (5—7,000 

 feet.) 



As a species It connects the Tasmanian S. flava with S. 

 minima, from New Zealand, 



Umbellifer ae . 

 Dichopetalum, 



A new genus of HydrocotylcEe. Flowers hermaphrodite, 

 equal. Lobes of the calyx white, membranous, petaloid, of
