at these altitudes. Here the rata is the dominant tree, and its irregularly- 
growing trunk and large horizontal boughs are thickly covered with sheets 
of H. multifidum and Н. villosum. Н. flabellatum, Н. rufescens, and 
T. Lyallii are most abundant in colonies on the bases of the old rata and 
totara trees. The kawhaka is also present with H. Malingi? upon its trunk, 
and H. Armstrongit is abundant on the stems of Quintinia. None of the 
typically lowland species occurs at these altitudes. These upland species 
are all present to the highest altitudes at which large trees are to be found, 
but it is noticeable that at about 2,200 ft. (this altitude varying according 
to whether the particular locality is a ridge or a flank) H. multifidum 
exchanges the epiphytic for the terrestrial station, and at the same time 
adopts its mountain form. Н. villosum, Н. Malingii, and Н. Armstrongu 
at these altitudes are the only true epiphytes, the other species men- 
tioned keeping to sheltered places at the very bases of the trees. Above 
2,600 ft. the forest is only shrubby, and H. multifidum, H. villosum, and 
Н. Armstrongvi are alone present in their characteristic stations. The summit 
Here, in a very stunted form, H. multifidum occurs in the heart of the

on the lower moss-covered boughs of the shrubs. 
A very deep sheltered ravine (Cedar Creek) descends from the shoulder 
of Mount Greenland into the upper Totara River, and the comparison of 
on other mountains situated nearer the main ranges, and on the ranges

the other forest-stories are also dense. The tall rata and kamahi trees are 
here clothed to their tops with H. villosum and H. multifidum, and with 
H. rarum and H. flabellatum in sheets over the lower third of their trunks.
