Phyllocladus trichomanoides, which is plentiful at the north, from about
35o south, (where it has been observed growing from the sea-side to
1200 feet altitude,) has its southern limits at 39 1/2o south, in the
mountains inland west from Hawke's Bay. Arthropdium cirrhatum,
a common littoral north plant, has its south limits at Cape Kidnappers,
in 38o 50' south. Trichomanes elongatum, has not been met with south
of Thames. Loxsoma Cunninghamii, for a long time only found at
one spot (the noted Kerikeri waterfall in the Bay of Islands,) has been
also met with at Whangarei, and in the Coromandel ranges. Doodia
caudata (or, media), so very common at the north, has not been seen
south of the Thames, except in one locality near Napier; which plant,
however, may prove to be a distinct species. Gymnogramma lepto-
phylla, plentiful near the head of Manukau Bay, has only been again
met with at Ahuriri and Cape Kidnappers. Lygodium articulatum,
a northern plant, has not been noticed south of the East Cape; and
Schizaea dichotomma appears to be wholly confined to the Dammara
(Kauri) forests.

(iii.) Plants found plentifully in the southern parts of the North
Island, but rarely, if ever, extending north beyond the East Cape.-
Among these the following may be noticed:- Elaeocarpus Hookerianus,
extends north to Tolaga Bay; Hypericum gramineum, from the coast
to 600 feet altitude, has not been noticed north of Table Cape. Coriaria
thymifolia, (several varieties), from the sea coast (Hawke's Bay) to 4000
feet, has not been generally met with north of Poverty Bay; but the
very small leaved species, C. angustissima, was found, in 1838, on Mount
Hikurangi, East Cape, and, subsequently, near the summits of the
Ruahine range, at an altitude of 4500 feet. Discaria Toumatou, a coast
plant, has not been detected north of Poverty Bay. Potentilla an-
serina, and Geum Magellanicum, extend from Cook's Straits to the
East Cape. Aciphylla squarrosa, found from the sea cost to 3500 feet
altitude, has not been noticed north of 40o 30' south. Craspedia
fimbrata, several varieties, from the coast to 1000 feet, extends north to
the East Cape. Microseris Forsteri, common near the coast, has its
north limit about Poverty Bay; where, too, it is very plentiful. Tarax-
acum Dens-leonis growing sparingly with the former, but often rising to
much higher elevation of 3000 feet, has not been detected north of
Tolaga Bay. Ourisia macrophylla, found plentifully at from 1500 to 3000
feet, has not been seen north of Poverty Bay. Calceolaria Sinclairii,
