Dunedin, assure me that the pod is always iudehiscent, the face of the 

 valves slowly decaying after the fall of the pod. I find that it is occa- 

 sionally 2-seeded. 



XXIV. 8AXIPRAGACEAE. 



Donatia novae-zealandiae Hook. f. 



Donatio, has been transferred to the Stylidiaceae by Milbraed in his 

 recently published monograph of the family (Engler's " Pflanzenreich,"' 

 heft 35). In this he has followed the late Baron Mueller, who suggested 

 the change as far back as 1879. No doubt the genus agrees with the 

 Stylidiaceae in the stamens being placed in the centre of an epigynous disc, 

 in the extrorse anthers, and in the placentation ; and the habit is very 

 similar to that of Phyllachne. But it differs markedly in the free petals, 

 and in the stamens not being united with the style into a '' colimin." We 

 may expect that systematists will not readily agree as to the position of 

 the genus. 



XXVII. Haloragaceae. 

 Myriophyllum pedunculatum Hook. f. 



In great abmidance by the margins of shallow ponds among the sand- 

 dmies on the west coast near Helensville, Kaipara. I suppose that it is 

 referable to the form which Schindler has distinguished as a separate species 

 under the name of M. Votschii {" Pflanzenreich," heft 2.3, p. 85). but the 

 differences appear to me to be very trivial. 



XXVIIT. Myrtaceae. 



Metrosideros robusta A. Cunn. 



Not uncommon at West Wanganui. to the south of Cape Farewell ;

Metrosideros scandens Soland. 



Dry ridges in lowland forests near Greymouth, Westland ; not un- 

 common : P. G. Morgan / The most southern locality from whence I have 

 seen specimens. 



XXXIII. Umbelliferae. 

 Aciphylla Dieffenbachii T. Kirk. 



I have to thank Mr. F. A. D. Cox, the veteran botanical explorer of 

 the Chatham Islands, for excellent specimens in fruit and a few in flower 

 of this remarkable plant. It is now exceedingly rare, having been destroyed 

 l>y sheep in most localities to which they have access, but it still lingers on 

 the faces of a few rocky cliffs near Te Tuku, on Mr. Bligh's sheep-station. 

 In this locality it was also seen by Captain Dorrien-Smith during his recent 

 visit to the Chatham Islands. 



In the " Students' Flora " Mr. T. Kirk hinted at the probability of the 

 plant constituting a separate genus, and I expressed the same opinion 

 in the Manual. Not only does it dift'er from Aciphylla in the flaccid 

 habit and large oblong much-compressed fruit, but a section of the fruit 

 shows that the vittae are of enormous size, quite unlike anything to be 

 seen in Li(/usiicum, Aciphylla, or Angelica. In the forthcoming " Illustra- 

 tions of the New Zealand Flora " it will accordingly be figured as the type 

 of a new genus, to which the name Coxella will be applied. I have much
