Araucaria Rulei. It attains, according to Mr. Duncan, a less gigantic height than any of its 
congeners. In habit it bears more readily comparison with the Chilian A. imbricata than with 
any of the Australian or Polynesian species, but differs already from the former in although 
acute yet not pungent leaves, which are not striolated, and from inch long. The closely and 
multifariously imbricated leaves distinguish it at once from A. Bidwillii. 
The enterprising traveller to whom we are indebted for the discovery of this noble tree, 
brought from the same locality another previously unknown Conifera, which may possibly also 
be referable to Araucaria, although it shares not the symmetrical ramifications of the genus, and 
bears rather some resemblance to certain states of Dacrydium elatum. The leaves are appressed 
in many rows, smaller and less acute than in A. Cookii, and the branchlets not distichous. 
CALLITRIS VERRUCOSA.

The review of a large number of specimens of the Sandarach pines, collected from almost 
every explored part of Australia, leads me to assume, that but very few species constitute this 
genus, even in the widest sense of its limitation. The following are the species which I feel 
inclined to consider as admissible : — 1. Callitris fruticosa, R. Br. (Frenela fruticosa, Endl. non 
Miquel), which enlarges in forest land away from the coast to a tree. — 2. Callitris cupressi - 
formis , Vent. (Frenela Ventenatii, Mirbel). — 3. Callitris Australis , R. Br. (Frenela Australis, 
Mirb.). — 4. Callitris verrucosa , , R. Br. (Frenela verrucosa, A. Cunn.). To this species most 
likely the Callitris robusta, R. Br., according to specimens from Rotten Nest Island, is referable. 
The presence of warts on the fruit affords by no means a note for recognizing this species. It 
is a tree of middle size, sometimes 80 feet high, and more or less pyramidal in growth, varying 
greatly in size of cones. It is smaller in foliage and thus thinner in branchlets than any of its 
Australian congeners. We have seen specimens gathered on Arnhem’s Land, on the Murchison 
River, on Middle Mount Barren, on Lake Torrens, on St. Vincent’s Gulf, on the Rivers Murray 
and Murrumbidgee, in New England and on the tropical east coast. It inhabits usually desert 
tracts. — 5. Callitris actinostrobus (Actinostrobus pyramidalis, Miq.). — 6. Callitris Macleayana 
(Octoclinis Macleayana, F. M.), which occasionally may be found alike to the normal and 
seemingly unalterable liexamerous division of the fruit of other species, with 6 instead of 8 
valves of the cone. The range and the characteristic marks of all these species will be early 
the subject of a special memoir.
