3,000 feet ; Lomaria procera, and its varieties, in all soils and situations, 

 from tlie coast to 4,000 feet ; NipJiobolus o'ujpestris ; Botrycliium virginicum, 

 in open lands, from tlie coast to 1,600 feet ; and Tmesipteris forsteri, 

 epiptytal, in forests from 300 to 2,500 feet. 



(2.) Northern plants occupying more tlian one area or zone, not found in 

 tlie soivtli parts of tlie island. 

 Among these, Drosera linata, a Bay of Islands plant, has been very 

 sparingly detected so far south as 39° 30'. Dysoxylum spectahile, not 

 uncommon from the Bay of Islands to the Thames, has also been detected 

 as far south as the E.iver Mohaka in Hawke Bay ; extreme altitude, 1,000 

 feet. Metrosideros tomentosa, a littoral plant, from the North Cape to 

 Tolaga Bay,* Alseuosmia, sp., whose chief habitat is around the Bay of 

 Islands, where, in shady dry woods, it is plentiful ; A. macropliylla was 

 found at Te Whau, Manukau Bay, in 1841 ; and, subsequently, a few plants 

 of A. lanhsii in one spot in the dense forests between the Eiver Manawatu 

 and "Wairarapa, but none intermediate, ascending to nearly 1,000 feet. 

 Geniostoma ligustrifolium, abundant at the Bay of Islands and farther north, 

 ascending to 1,200 feet ; a straggling plant (having thicker leaves) has 

 been seen as far south as the woods at Hawke Bay ; the only plant, 

 however, noticed south of the East Cape. Vitex littoralis, a tree very 

 plentiful at the north, extending quite across the Island, and growing as 

 diffusely on the immediate sea coast as on the high lands, ascending to 

 1,500 feet, is little known south of the East Cape ; one tree, how- 

 ever, is said to be on the islet Mokoia in the large lake at Eotorua, 

 and one is also at Table Cape (north side), its extreme southern limit. 

 Avicennia officinalis, a maritime plant, very plentiful from the North Cape 

 to about 371° south ; the mouth of the Waikato Eiver on the west, and 

 within Tauranga Harbour on the East Coast being its south limits. Fer- 

 soonia toro, has not been met with south of Whangarei Bay. Santalum 

 cimningJiamii, and its varieties, plentiful at the north, has not been noticed 

 south of 38° ; yet, at the head of the Wairarapa Valley (just at the entrance 

 of the long forest), in about 41° south, two trees were most unexpectedly 

 found standing together ; no more, however, were detected in a journey of 

 three or four days through that forest, performed on several occasions. 

 Tropins opaca {ot^ Epicarpurusmicrophyllus) has its south limits at Tolaga Bay, 

 or about 39° south. JDammara austraUs, which grows from the sea side to an 

 altitude of 1,500 feet, in nearly all soils and situations, though its favourite 

 soil is a stiff sterile clay, is very plentiful quite across the island from the 

 North Cape to the Thames, but has its limits on the East Coast at 37|° south
