Haloragis depressa, Walp. 



Here, too, we are indebted to Dr. Schindler for pointing out that the 

 Australian and New Zealand plants associated by Hooker and Bentham 

 under the name of H. depressa must be separated. The New Zealand plant 

 has rather large oblong-obovoid tetragonous fruit, with very large per- 

 sistent styles, decurved between the calyx-lobes, whereas the Australian 

 plant has small oblong barely tetragonous fruit, and the persistent styles 

 are much smaller and erect. Schindler applies the name of depressa to the 

 Australian species, using Kirk's name of imiflora for the New Zealand plant. 

 Evidently he did not fully trace the history of the name depressa, or he 

 must have noticed that it was first applied by Allan Cunningham to the 

 New Zealand plant {Goniocarpus depressus, A. Cunn., Precur., n. 531). 

 Consequently our plant must retain the name of depressa. Schindler divides 

 the species into the two varieties, genuina (which is equivalent to H. imi- 

 flora, T. Kirk) and bibracteolata. But Cmmingham's type certainly fails 

 under the second variety, to which also Buchanan's H. aggregata must 

 be referred. The two varieties will therefore be more correctly styled 

 var. a, aggregata, and var. b, uniflora, the latter name being equivalent 

 to Schindler's var. genuina. Kirk's name of serpyUifolia must be aban- 

 doned on account of the fact that the New Zealand plant differs from 

 the Australian var. serpyUifolia. 



Haloragis spicata, Petrie. 



This is placed by Schindler as a variety of //. depressa. In the Manual 

 I have hinted that this is its correct position. 



The following arrangement is therefore the one which I now follow of 

 the New Zealand species of Haloragis : — 



1. H. erecta, Schindl. {H. alata, Jacq.). 



2. H. cartilaginea, Cheesem. (//. alata, var. cartilaginea, Cheesem.). 



3. //. incana, Walp. {H. tetragyna, Hook, f., non Labill, var. a ; H. 

 aggregata, Schindl., non Buch.). 



i. H. procumbens, Cheesm. {H. tetragyna, var. diffusa, Hook. f. ; H. 

 aggregata, var. diffusa, Schindl. ; H. diffusa, Cockayne, non Diels). 



5. H. depressa, Walp. Var. a, aggregata, T. Kirk (//. aggregata, Buch., 

 non Schindl. ; //. uniflora, var. bibracteolata, Schindl.). Var. 6, uniflora, 

 Cheesm. (//. uniflora, T. Kirk ; H. uniflora, var. serpyUifolia, T. Kirk, but 

 not H. depressa, var. serpyUifolia, Benth. ; H. uniflora, var. genuina, 

 Schindl.). Var. c, spicata, Schindl. {H. spicata, Petrie). 



6. H. micrantha, R. Br. 



XXVIII. Myrtace^. 

 Myrtus Ralphii, Hook. f. 



Tauroa (Reef Point), near Ahipara, Mangonui County ; R. H. Mat- 

 thews ! This is a marked extension of the range of this species, the northern 

 limit of which had been beheved to be at Whangarei. 



XXIX. Onagrace^. 

 Epilobium pycnostachyum, Haussk. 



Shingle - slopes on Ben Nevis, Nelson, and on Waingaro Peak, north- 

 west Nelson ; F. G. Gibbs ! These are the most northern localities yet 

 recorded.
