I. KEY TO THE NATURAL ORDERS, ETC., OF FLOWERING PLANTS. 
(Chiefly adapted from Lindley’s ' Vegetable Kingdom?) 
Class T. Dicotyledons. Stem, when perennial, with pith, rings of wood, 
and separable bark. Leaves with branching netted veins. Leaflets or lobes 
of the perianth 4 or 5, or multiples of 4 or 5 (in the third division the 
perianth is often absent or imperfect). Embryo with 2 opposite cotyledons; 
radicle elongating in germination. 
The exceptions to each of the foregoing characters are very numerous, but a little practice, 
and the tact and knowledge that practice alone can give, will enable the student to decide at 
once whether almost any New Zealand flowering plant belongs to this or the following Class. 
Class II. Monocotyledons. Stem, when perennial, without rings of 
wood or separable bark ; the wood-bundles being isolated and scattered, ap- 
parently promiscuously through the cellular-tissue. Leaves (never opposite in 
New Zealand, often sheathing at the base) with parallel veins joined by straight 
cross-veinlets. Leaflets or lobes of the perianth 3 or 6, rarely 4 ; in grasses 
and sedges the perianth is imperfect or 0, and the flowers enclosed in dry 
imbricating scales. Embryo with one cotyledon or two alternate ones ; radicle 
not elongating in germination, but giving off root-fibres. 
Palms and Cordylines are the only New Zealand trees of this class. Rldpogonum and 
Freycinetia the only shrubs. Rhipogonum and Callixene have somewhat netted veins. 
Class III. Cryptogamia. See p. lxvi. 
CLASS I. DICOTYLEDONS. 
I. Flowers having both calyx and corolla, the latter polypetalous. 
A. Polyandrous. Stamens more than 20.
