flowers on slender pedicels } inch long; involucres of about six simple

at the back. 
South Island: Nelson—Roto Iti; Amuri; Lake Guyon. Canterbury— 
Pukunui Creek.—Altitude, 2,000-8,000 feet. 
Specimens without locality or collector’s name are in the herbarium of 
the Colonial Museum. 
This species has been confused by collectors with P. trifoliolata, of 
which Professor Oliver considers it a variety,—an opinion with which I 
cannot agree, its closest affinity being with P. roughii and P. hydrocotyloides. 
It is easily recoguized in all stages by its pale green shining foliage, and 
never forms the densely-matted patches so characteristic of P. hydrocoty- 
loides, from which it is further distinguished by its less coriaceous leaves, 
proliferous umbels, and pedicellate flowers. It is distinguished from P. 
roughii by the ternate leaflets, few flowered umbels, fruit shorter than the 
pedicels, and carpels not rounded at the back. 
A single specimen in my possession has the peduncles branched with a 
single pedunculate umbel in the fork of each.

Coprosma arborea. 
A tree 20-25 feet high; trunk 8-12 inches in diameter; wood

terminal; calyx narrow, deeply 4—5-cleft, minutely ciliated ; corolla bell- 
shaped, 4-5-cleft; lobes broad, obtuse. Female flowers in 4-5-flowered 
fascicles ; calyx 45-dobed. lobes obtuse, minutely ciliated; corolla 4-5- 
partite nearly to the base; lobes ligulate, spreading; styles slender, short. 
Fruit crowded ; globoso-ovoid, with obscure traces of the calyx limb at the 
apex, white, translucent. : 
North Island.—From Mongonui southwards to the head of the Hauraki 
Gulf. Abundant on Waiheke Island. 
In the * Handbook of the N.Z. Flora” this species is confused with C. 
spathulata* to which it is closely allied, and from which it is distinguished 
* I append an amended description of C. spathulata, A. Cunn. A sparingly-branched 
shrub 2—6 feet high; branches spreading or straggling; leaves distant, orbicular. 
spathulate, emarginate or obcordate, abruptly narrowed into the winged petiole, blade 
longer or shorter than the petiole, coriaceous, veins obscure. Male flowers in 2-3- 
flowered fascicles ; calyx 4—5-lobed; corolla funnel-shaped, 4-5-partite divided for about 
half its length ; lobes narrow. Female—calyx bell-shaped, 4—5-cleft ; corolla 4—5- partite’ 
divided for less than half its length ; segments narrow; style 3-2 inch long. Fruit ovoid, 
. solitary, shortly peduncled, black, shining, crowned by the limb of the calyx.
