94 FLORA OF NEW ZEALAND. [ Araliacee. 
4. Panax Zdgerleyi, Hook. fil.; arborea, foliis longe petiolatis simplicibus 1-foliolatis (junioribus 
3-foliolatis), foliolis magnis ellipticis lanceolatis lineari-oblongisve acuminatis integerrimis coriaceis lucidis, 
umbellis axillaribus terminalibusque, umbellulis 8-10-floris, ovarii loculis stylisque 3—4. 
Has. Northern Island; mountainous parts of the interior, Zdgerley, Colenso. Middle Island; Nelson, 
Bidwill ; Port Preservation, Lyall. Nat. name, “ Rau-Raua,” Zdgerley. 
This fine species is very similar to P. simplex, but may be recognized at once by its larger foliage, of which the 
leaflets vary in breadth and in length from 2 to 9 inches, and are quite entire, and by the three- to four-celled ovary, 
three to four styles, and consequently three- to four-celled and -seeded fruit. Mr. Colenso sends a seedling plant 
with five-foliolate leaves, and deeply sinuato-pinnatifid leaflets, as belonging to this plant, just.as Mr. Bidwill does 
(apparently the same seedlings) for P. simplex. This is a point left for the investigation of the colonist. P. Edgerleyi 
would by some botanists be placed in Aralia, on account of the three- to four-celled ovarium, etc.; but its nearest, 
and indeed very near, ally is P. simplex. Mr. Edgerley remarks, that the natives rub their bodies with the fragrant 
leaves, whence the native name. 
$ e. Leaves 3-1 -foliolate. Petioles with sheathing stipules. 
5. Panax arborea, Forst.; arborea, robusta, foliis longe petiolatis stipulatis 5-7-foliolatis, foliolis 
petiolatis late v. anguste oblongis subacutis grosse sinuato-dentatis valde coriaceis, umbellis amplis ter- 
minalibus axillaribusque longe pedunculatis compositis radiatis, umbellulis multifloris, floribus dioicis,

Has. Throughout the Islands, abundant, Forster, etc. Nat. names, “ Wawa-Paku," R. Cunn.; 
* Whau-whau Paku,” Colenso. (Cultivated in England.) 
A robust tree, 12-20 feet high. Branches round, as thick as the finger. Pešioles stout, 4—8 inches long, with a 
broad base, and large adnate sheathing stipules. Leaflets five to seven, very coriaceous, glossy, 4—6 inches long, 
on petioles 1-1 inch, oblong, variable in breadth, deeply sinuato-serrate. Inflorescence unisexual, very spreading, 
of eight to twelve radiating peduncles, sometimes collected on a common stout peduncle, all of about equal length, 
1-4 inches long, bearing about twelve pedicellate eight- to ten-flowered umbels, collected into a globose head. 
Peduncles 2-4 lines long. Styles and cells of the ovary two.—The young inflorescence is, when in bud, enclosed in 
thick, brown, imbricating, gummy scales; and similar ones form a covering or involucre to the partial umbels. All 
are very deciduous. 
6. Panax Colensoi, Hook. fil.; arborea, robusta, folus longe petiolatis stipulatis 3-7-foliolatis, foliolis 
sessilibus oblongo-lanceolatis subacutis grosse sinuato-dentatis valde coriaceis, umbellis terminalibus latera- 
libusgue pauciradiatis, floribus dioicis, stylis 2. Tas. XXI.

A shrub 6-15 feet high. In most respects this closely resembles the P. arborea, but the leaflets are sessile on 
the petiole, and the umbels are fewer-flowered and less effuse. In other respects these two species are so alike that 
this requires no further description. Mr. Colenso sends a specimen with the leaflets deeply pinnatifid, and the lobes 
dentate, as the young state of this. Its petioles are not stipulate.—PrATE XXI. Fig. 1, young plant; 2, male 
umbel; 3, 4, male flowers; 5, 6, female flowers; 7, female umbel ; 8, fruit :—all but fig. 1, 2, and 7 magnified.
