ON THE HUON PINE, &c. 143 
There are two Brazilian, and lastly, three Cape species of 
this genus, making about thirty southern species in all. 
XI. Dacrypium, Banks; a much rarer genus than the 
former. 1. D. cupressinum, Sol. the Dimou Pine of New 
Zealand. 2. D. Colensoi, Hook. (Ic. Plant. t. 548) from the 
same island. 3. D. /azifolium,* n. sp.; also from New Zea- 
land. 4. D. Franklinii, Hook. fil., the Huon Pine; vide infra. 
XII. PayLLocuapus, Rich. 1. P. aspleniifolia, Rich. 
* Celery-topped Pine? of Tasmania, and 2. P. trichoma- 
noides, Don, the “ Tauehaha" of the New Zealanders. 
From the above list it will be seen that four genera are pe- 
culiar to the Southern Hemisphere, Araucaria, Phyllocladus, 
Microcachrys, and Arthrotaxis. Three others have their 
maximum to the south of the tropies, Callitris, Podocarpus, 
and Dacrydium. Dammara has one species in each hemi- 
sphere. Thuja is equally divided between the two; whilst 
Juniperus and Cupressus are barely, if at all, represented, ex- 
cept perhaps the latter by Arthrotazis.

* DacRYDIUM laxifolium, Hook, fil.; caule humili fruticoso, ramis pro- 
stratis laxe ramosis gracilibus, foliis undique insertis sparsis patentibus 
linearibus obtusis coriaceis supra concavis supremis imbricatis ovatis 
multo brevioribus dorso carinatis, fructibus terminalibus solitariis 
erectis, 
Haz. New Zealand, near the summit of Tongariro. Mr. Bidwill (No. 5), 
Colenso (No. 60.) ae 
ether or not the present be an alpine form of some larger species, 
lam unable to say. It is marked by Mr. Bidwill as “ Rima,” from dE 
Which I suppose that gentleman considered this plant to be a state 
Of the D. cupressinum ; but it is a wholly different species from that, in no- 
Way resembling what might from analogy be assumed as the mountain 
vem of that tree. Iam indeed more inclined to suppose it a strictly 
alpine species, like the Podocarpus alpina, Br. of Tasmania, which is 
only known as a small mountain plant. The leaves of the present are 
very lax on the stem, like those of a Sedum, patent and more flaccid 
is usual amongst the Conifere; the largest are not above two linesin —— 
gth, convex or keeled below, and more or less concave above; they are — — 
Contracted at the base and not decurrent on the branches: those at the — — 
"Pes are much smaller and closely imbricated. The whole length —— 
of our specimens of the entire plant, which are very good, does not exceed.
