PLATE 60.—AZORELLA ROUGHII. 
Famity UMBELLIFER 4. } [Genus AZORELLA, Lam. 
Azorella Roughii, Benth. & Hook. f. ex T. Kirk, Students’ Fl. 192; Cheesem. Man. N.Z. Fl. 
201. 
Azorella Rough was one of the discoveries of Captain D. Rough, who 
between the years 1858 and 1862 gave a considerable amount of attention to 
the mountain - flora of the Nelson Provincial District. His specimens were 
obtained on Dun Mountain, near Nelson—an excellent collecting-ground, and one 
on which many interesting plants were noticed for the first time, as, for instance, 
Stellaria Roughw, Lobelia “‘Roughii, Myosotis Monroi, Pimelea Suteri, &c. In 1862 
the species were published in the ** Handbook” by Sir J. D. Hooker under the 
name it now bears. Its range is much more limited than that of A. Haastii, and 
so far I have not seen specimens from the south of the Spenser Mountains. — It is 
abundant in many parts of the Dun Mountain Range, extending southwards along 
the Raglan Mountains to the Wairau Gorge, where ‘T collected it many years ago. 
Still further south it has been gathered by Mr. T. Kirk and myself on several of 
the mountains flanking the Waiau and Clarence Valleys. Its north-eastern limit 
appears to be on Mount Stokes, from whence I have seen specimens obtained by 
Mr. Macmahon. Mr. Gibbs and myself have gathered it on Mount Arthur and 
other peaks in north-western Nelson; and I “have seen specimens collected by 
Mr. Townson in some locality near Westport, although it is not mentioned in his 
list of Westport plants printed in the ‘ Transactions of the New Zealand Institute ” 
(vol. xxxix, p. 380). 
As a species A. Roughii comes very close to A. Haastw, of which it has the 
size, habit, and inflorescence. But it can always be readily separated by the 
3-5-foliolate or -partite leaves. A. pallida is also allied, but is much smaller and 
more slender, and the leaves are much more membranous.
