genera, confining that name to the original N. African plant, and 
applying Mirbel’s name of Frenela to the Australian species. 
Vllf. Athrotaxis, Don. Founded on two Tasmanian plants, 
1. A. selaginoides, and 2. A. cupressoides; to these another has 
been added, 3. A. laxifolia, Hook. (Ic. Plant, t. 573). 
IX. Microcachrvs, Hook. fil. vid. infra, comprising a single 
species, discovered by Mr. Gunn in the interior of Tasmania. 
X. Podocarfus, L'H&r. The most extensive of all the 
southern genera of Coniferte, upon which Mr. Bennett has pub¬ 
lished an excellent dissertation.* There are three species from 
Australia, 1. P. elata, Br. 2. P. spinulosa, Br. 3. P. ensifolia, 
Br.;—and two from Tasmania, 4. P. alpina, Br., 5. P. Lawrencii 
(vid. infra). Six inhabit the New Zealand Island, 6. P. spicata, 
the Mai or Matai. 7. P. ferruginea, Don, the Miro or Maira. 
8. P. Totarra, Don, the Totarra. 9. P. dacrydioides, A. Rich., 
the most abundant of the New Zealand species in the neighbour¬ 
hood of the Bay of Islands, “ Kaikatia" of the natives. 10. P. 
? biformis, Hook. 11. P. nivalis, Hook. (Ic. Plant, t. 582), this 
is possibly a variety or alpine state of the P. Totarra. In Chili 
there are also several species, perhaps not less than three: 12. P. 
Chilina, Rich.; this, and two others, are in the Hookerian Her¬ 
barium. There are two Brazilian, and lastly, three Cape species, 
of this genus, making about thirty southern species in all. 
XI. Dacrydium, 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. laxifolium, f n. sp.; also from New Zealand. 4. D. Franklinii, 
Hook, fib, the Huon Pine; vide infra.

IIab. New Zealand, near the summit of Tongariro, Mr. Jlidwill, (No. 5), Colenso, (No. 60). 
Whether or noc the present be an alpine form of some larger species, I am unable to say. 
It is marked by Mr. Hid will, as u IUma,” from 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 bo assumed a> the mountain form of that tree. I 
am indeed more inclined to suppose it a strictly alpine species, like the Podocarpus alpina, 
Br. of Tasmania, which is known only 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 than is usual amongst 
the Conifer# ; the largest are not above two lines in length, convex or keeled below, and 
more or less concave above; they are contracted at the base and not deeurrent on the 
hranches : those at the apices are much smaller and closely imbricated. The whole length of 
our specimens of the entire plant., which are very good, does not exceed a span, The fruit* 
are abundant, terminal, and erect.
