XXXIV. ARALIACEJE. 
[Panax. 
mose. Flowers rather large. Fruit subglobose, as large as a’ pea, 5-celled, 
the 5 styles connate into a cone, with their summits free and recurved. — 
Hook. lc. PI. t. 583-4. 
Common in forests throughout the islands, Banks and Solander , etc. Chatham Islands, 
Dieff'enbach. A very puzzling plant ; the lower and younger leaves are always 3-foliolate, 
the upper 1-foliolate or simple, all excessively coriaceous. For notes on some supposed 
varieties of this, see end of genus. 
6. P. longissimum, Hook.f., n. sp. Stem forming a straight, slender, 
erect, simple rod, 4-10 tt. high ; bark dark-green, striped with brown. Leaves 
alt uniform, quite simple, 6-18 in. long, in. broad, spreading or droop- 
ing, excessively stiff, coriaceous, coarsely regularly or irregularly toothed, 
dirtv-purple below, very deep-greeu above, with often a light-green spot at 
the base of each tooth ; petiole very short, exstipulate, not jointed with the 
blade ; midrib very thick ; veins 0. 
Throughout the islands, Banks and Solander, etc., from the Bay of Islands to Otago. 
This remarkable plant has been for tifteen years in cultivation at Kew (as a state of P. cras- 
sifolium), and never changes its habit ; it has been collected by Banks, and many succeeding 
travellers, but no one has identified any flower or fruit with it. I have, however, in the 
Herbarium male flowers and leaves of a Panax closely resembling P. crass folium, differing 
chiefly from that plant in the less coriaceous, more acute leaves, with more regular serratures, 
that may prove to belong to this. 
7. P. Lessonii, DC. — Ar alia Lesson'd, FI. N. Z. i. 96. A small, glabrous 
tree, branches very stout. Leaves in old plants 3-5-foliolate; leaflets 1-4 
in. long, sessile, oblong- or obovate-lanceolate, subacute, more or less sinuate- 
serrated or quite entire, very thick and coriaceous, not shining ; nerves very 
indistinct ; petiole 4 8 in. long, stout or slender, neither sheathing nor stipu- 
late at the base. Umbels branched, on long stout peduncles ; pedicels race- 
mose, unisexual. Flowers rather large. Fruit ovoid, ^ in. long, 5-celled, 
with 5 styles connate into a cone, and very short, recurved tips. 
Northern Island: east coast, Cunningham; Auckland, Sinclair. Middle Island: 
Bream Bay, D'Urville. 
8. P. Colensoi, Hook.f. FI. N. Z. i. 94. t. 21. A small tree; branches 
stout. Leaves glossy, on long petioles, 3-5-foliolate; leaflets 4-6 in. long, 
very coriaceous, sessile or very shortly petioled, obovate- or oblong-lanceolate, 
coarsely serrated, veins very indistinct; petiole stout, 6-10 in. long, with a 
short 2-lobed coriaceous sheath. Umbels compound, terminal; primary rays 
long, stout, divaricating, in the largest specimens 2-3 in. ; secondary rays 1 
in., pedicels short. Calyx-limb truncate or sinuate. Fruit flattened, nearly 
orbicular, 2-ceIled, with 2 divergent styles. 
Northern Island: Ruahine Mountains and Tararua, C-olenso. Middle Island: Otago, 
Lindsay, Hector. Southern Island : Herb. A. liichard. Ivy-tree of Otago. Colenso 
sends as a young state of this, a plant with pinnatifid leaflets, w'hich perhaps belongs to 
P. Sinclairii, for both Lindsay and Hector observe that the leaves are 3-5-foliolate in all 
stages, and never sinuate or lobed. Wood useless, trunk exuding large quantities of gum, 
Buchanan. Hector observes that it is the Aralia trifolia of Sydney Garden. 
9. P. arboreum, Forst. ; — FI. N. Z. i. 94. A robust, leafy, glossy 
tree, 12-20 ft. high ; brauches stout. Leaves on long petioles, 5-7 -foliolate ; 
leaflets with petioles |-1 in. long, very coriaceous, 4-6 in. long, broadly or 
narrowly oblong or obovate-oblong, subacute, sinuate-serrate ; veins distinct;
