the style (as in the Styhdiete), wliich, though not complete m Bonatia, 

 nevertheless places the filaments really in the centre of the flower, and en- 

 tirely away from the calyx ; (2) the minute embryo similar to that of Styli- 

 dium though its position may not be near the hilum ; (3) the placentation, 

 which is that of Stylidium, and not that of the normal Saxifrages ; (4) the 

 internal structure of the seeds, which agrees better with that of Stylidiese 

 than of Saxifragete ; and (5) the normal number of two stamens in Donatia, 

 which is not represented in any other Saxifrage. From these various con- 

 siderations he places the genus among the StyUdiese, of which the following 

 enumeration of the known genera is given, which will prove useful to New 

 Zealand botanists.

Phyllachne haastii, Berggr. 



Leaves imbricating at the oblong plano-convex base, semi-terete, scarcely 

 thickened at the apex, with a simple nerve, upper half of the column ex- 

 serted, stigmatic lobes oblong, recurved, capsule turbinate, seeds 6-12 on 

 the central undivided placenta. 



Kelly's Hill, Canterbury Alps. 



This is the plant which I referred to P. colensoi, Hook f., in Lund's 

 " Physiograph. Saltskaps Minnesskrift," 1878, tab. III., figures 1-27. 

 From that plant this is distinguished by the dull olive-green leaves, the 

 upper half of which is terete, and not swollen at the tips. The single nerve 

 is unbranched, whereas in P. colensoi there is a lateral branch on each side. 

 The seeds are few in number, and the upper part of the placenta is not 

 divided into two branches as in that species.
