Azorella.| UMBELLIFERA. 201 
4. A. Haastii, Benth. and Hook. f. l.c.—Exceedingly variable 
in size, 1-10in. high. Rhizome stout, branched, with tufts of 
radical leaves at the tips, often with prostrate or ascending leafy 
and flowering branches. Leaves 4—2in. diam., reniform or orbi- 
cular with usually an open sinus, glabrous or sparingly setose, 
coriaceous or almost fleshy, bright-green and glossy, crenate-lobed ; 
lobes broad, shallow, rounded; margins thickened, almost carti- 
laginous ; petioles variable in length, 4-8 in. ; stipules broad, usu- 
ally more or less ciliate at the tips. Umbels peduncled, many- 
flowered, often 1-3 secondary ones arising from the base of the 
primary one and far exceeding it ; floral leaves cuneate, 3-4-toothed 
or -lobed ; involucral bracts linear-oblong, obtuse. Pedicels usually 
much longer than the oblong tetragonous fruit; carpels obscurely 
5-ribbed.—Kirk, Students’ 1.192. Pozoa Haastii, Hook. f. Handb.

This varies much in most of its characters, and as a species is doubtfully 
distinct from A. reniformis. Ordinarily, however, it can be separated from that 
plant by the ciliate stipules, many-flowered umbels, and long fruiting pedicels. 
But the stipules are sometimes entire, and dwarf specimens frequently have 
short pedicels. Mr. Colenso’s Pozoa elegans (as proved by the type specimens in 
his herbarium, labelled in his own handwriting) is founded upon the tips of the 
flowering shoots of d. Haastii. He describes the leaves as ‘‘ 2~3-foliolate,”’ 
having evidently mistaken the approximate floral leaves for parts of a compound 
leaf. 
5. A. Roughii, Benth. and Hook. f. l.c.—Perfectly glabrous, 
smooth and shining. Rhizome stout, branched, terminated by 
numerous radical leaves, and usually with prostrate or ascending 
leafy flowering branches. Leaves 3-1}in. diam., orbicular or reni- 
form, coriaceous, 3—d-foliolate or -partite; leaflets sessile, broadly 
obcuneate, deeply crenate-toothed or lobed at the tip; lobes 
rounded ; petioles 1-6 in. long; stipules usually laciniate. Flower- 
ing shoots often exceeding the leaves; umbels many-flowered, 
usually 1-3 secondary ones arising from the base of the primary 
and overtopping it; involucral bracts linear-oblong, obtuse. Pedi- 
cels usually longer than the linear-oblong fruit; carpels rounded 
at the back, 5-ribbed.—Kirk, Students’ Fl. 192. Pozoa Roughii, 
Hook. f. Handb. N.Z. Fi. 89. 
SoutH Isnranp: Mountains of Nelson and Marlborough, from Dun Moun- 
tain to the Upper Clarence and Waiau, not uncommon. 2500-5000 ft. 
December—February. 
This has the same habit as A. Haastii, but can always be recognised by the 
divided leaves. I have seen no specimens from the south of Lake Tennyson and 
the Upper Waiau.
