ant, and about the same height as the Olearia. Lepyrodia 

 traversii is reappearing, but to much less extent than in the 

 original formation. Gentiana uvibellata is more plentiful 

 than before. Finally, there is a certain amount of Drosera 

 binata, Utricularia, Pratia arenaria, and Isolepis sp. 



(e ) Dry Ridge near Lake Bangatapu ; burning quite 

 recent. — Original vegetation, Phormium tenax, Dracophyllum 

 arboreum and D. paludosum, Cyathodes robusta ; under- 

 growth of Lomaria procera, Luzula sp. in large quantities, 

 Pteris esculenta, Gnaphalium filicaule. The reproduced 

 vegetation consists of Pteris esculenta, Hydrocotyle ■mos- 

 chata, Gentiana umbellata, Erechtites sp., Gnaphalium luteo- 

 album, Lomaria procera, Accena novce-zelandice, Epilobium 

 novce-zelandim. 



( f.) Burnt Forest. — It is almost unknown for forest to be 

 burnt in Chatham Island, but this was an isolated patch 

 round which the bog fire mast have raged furiously Where 

 the forest stood is now one dense mass of tree ferns coming 

 into leaf. 



(g.) Burnt Vegetation of Tableland Dry Ridges. — On the 

 very driest ground, where formerly Cyathodes robusta was 

 tbe leading plant, the vegetation of which has probably been 

 burned several times, Pteris esculenta is very abundant. 

 Also in fair numbers are Dracophyllum paludosum seedlings, 

 Lomaria procera, Epilobium pedunculare, Accena novce- 

 zelandice, Luzula sp. 



(h.) Piece of Vegetation near Lake Te Kua Taupo ; pro- 

 bably burnt only once, and that many years ago. — Dracophyllum 

 paludosum, 38 cm. tall, forms to the eye the almost entire 

 vegetation, except for here and there a few plants of Olearia 

 semidentata of nearly the same height. All the plants of 

 D. paludosum grow very closely together, but here and there 

 are small patches where Dracophyllum is absent. In such 

 places Glcichenia circinata 21 cm. tall, mixed with a small 

 quantity of Pteris esculenta, is present. Where the Gleichenia 

 is lower and without any dead fronds at its base the bare 

 black soil becomes exposed, and in it are growing Cala- 

 denia bifolia and Gentiana umbellata. On one patch 

 59 cm. by 29 cm. are fifteen plants of the orchid and four 

 of the gentian. Often through the tall Gleichenia a 

 few plants of Dracophyllum emerge for a distance of 

 12 cm. The ground m which the Dracophyllum is growing 

 is covered for a depth of perhaps 2 cm. with shed leaves, 

 growing amongst which is Pratia arenaria. In places a 

 little Gnaphalium filicaule is present, and in some of the 

 open patches Pteris esculenta is more abundant than Glei- 

 chenia circinata. In the largest open patches Uncinia sp. 

 and Accena novce-zelandice are present ; also Gentiana umbel-
