and on the "West Coast at Kauri Eiver (Kawhia), 38° 4' south, where are a 

 few stunted trees. The writer well remembers seeing, in 1841, a straggling 

 tree on the west bank of the Eiver "Waikato, a little below Ngaruawahia. 

 Libocedrus doniana keeps always in the interior on high ground (500 to 

 2,000 feet) , from 35° to the Thames seems to be its limit. It is, however, 

 strongly suspected that there are two species of this genus in the North 

 Island ; the Libocedrus growing in dense thickets on the Euahine Mountains, 

 has never yet been found in fruit,* and appears in foliage different from the 

 Bay of Islands plant, which is also of more robust growth. JPhyllocladus 

 trichomanoides, which is plentiful at the north, from about 35° south (where 

 it has been observed growing from the sea-side to 1,200 feet altitude), has 

 its southern limit at 39|° south, in the mountains inland west from Hawke 

 Bay. Arthropodium cirrhatum, a common littoral northern plant, has its south 

 limit at Cape Kidnappers, in 38° 50' south. Tricliomanes elongatum has not 

 been met with south of the Thames. Loxsoma cunningliamii, 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 ; this 

 plant, however, may prove to be a distinct species. Gymnogramme lepto- 

 phylla, plentiful near the head of Manukau Bay, has only been again met 

 with at Ahuriri and Cape Kidnappers. Lygodium articulatitm, a northern 

 plant, has not been noticed south of the East Cape ; and Schizcsa dichotoma 

 appears to be wholly confined to the Dammara (kauri) forests. 



(3.) Plants found plentifully in the southern parts of the North Island, 

 hut rarely, if ever, extending north beyond the East Cape. 

 Among these the following may be noticed : — Elceocarjms hooTcerianus, 

 extending north to Tolaga Bay ; Hypericum graminexim, from the coast to 

 600 feet altitude, has not been noticed north of Table Cape. Coriaria thymi- 

 folia (several varieties), from the sea coast (Hawke Bay) to 4,000 feet, has 

 not been generally met with north of Poverty Bay ; but the very small 

 leaved species, G. angustissima, was found in 1838 on Mount Hikurangi, 

 East Cape, and subsequently near the summits of the Euahine range, at an 

 altitude of 4,500 feet. Discaria toumatou,, a coast plant, has not been 

 detected north of Poverty Bay. Potentilla anserina and Geum magellanicum 

 extend from Cook Strait to the East Cape. Aciphylla sqiiarrosa, found 

 from the sea coast to 3,500 feet altitude, has not been noticed north of 

 40° 30' south. Graspedia flnibriata, several varieties, from the coast to 1,000 

 feet, extends north to the East Cape. Microseris forsteri, common near the
