Systematic contributions to the Flora of Australia : 

 Bonder's diagnoses of 76 new Algse, belonging to Preiss's 

 collection from the Swan River (Bot. Zeit., 1845, 

 pp. 49-57) Berkeley's new Fungi (54 sp.), from the 

 same locality, and belonging to Drummond's collection. 



J. D. Hooker has written a memoir upon the distri- 

 bution of the Coniferae in the southern hemisphere (Lond. 

 Journ. of Bot., 1845, pp. 137-157). 



Van Diemen's Land contains ten different Coniferse, which are endemic to 

 the island. They occur in limited localities, and most of them were dis- 

 covered by Gunn ; they are Callitris australis Br. (Oyster-bay pine), a tree 

 from 50' 70' in height ; C. Gunnii J. D. Hook, (native cypress), 6' 10' in 

 height ; Arthrotaxis, 3 sp. ; Micocachrys tetragona J. D. Hook., a tree from 

 15' 20' high ; Podocarpus alpina Br., a shrub on Mount Wellington, at an 

 altitude of from 3' 4000' ; Podocarpus Lawrencii J. D. Hook. ; Phyllocladus 

 asplenifolia Rich, (celery-topped pine), 50' 60' high ; Dacrydium Franklinii 

 J. D. Hook. (Huon-pine), the most beautiful tree of them all, from 60' to 3 00' 

 in height, with a diameter of from 2' 8', of limited occurrence, but used at 

 the harbour of Macquarie as ship-timber. 



Sketch of the distribution of the Coniferse as yet discovered in the southern 

 hemisphere : 16 species in New Holland (10 Callitris, 4 Podocarpus and 2 

 Arauearia at Moreton Bay), 10 species in Tasmania (vid. sup.), 13 species 

 in New Zealand and the South Sea Islands (6 species of Podocarpus, of 

 which the Kaikatia, Podocarpus dacrydioides Rich, is most common at the 

 Bay of Islands, 3 Dacrydium, Thuja Doniana Hook., Phyllocladus tricho- 

 manoides Don., Dammara Australis = Kauri pine, Arauearia excelsa Ait. 

 =Norfolk Island pine, probably confined to this island ; 8 species in South 

 America (4 Podocarpus in Chili and the Brazils, Thuja chilensis Hook. ; 

 andina Popp. ; Thuja tetragona Hook.= Alerse of Chiloe, Arauearia bra- 

 sz'/^Tm's Brazilian pine, Arauearia imbricata = Chili pine, on the Andes, 

 from 37 to 46 S. lat. ; Juniperus uvifera Don., from Cape Horn, remains 

 doubtful ; about 6 species in the South of Africa and the Mauritius (2 Podo- 

 carpus, 3 Pachylepis, including Pachylepis Commersoni from the Mauritius, 

 and Juniperus capensis Lam., doubtful. 



We have now received 15 Parts of J. D. Hooker's 

 illustrated work upon his Antarctic Voyage. (The Botany 

 of the Antarctic Voyage. London, 1845, 4to.) 



The character of the vegetation of Lord Auckland's islands is more clearly 

 described than before (Ann. Hep. for 1843). It was previously mentioned 

 that these islands, the volcanic soil of which ascends in the form of gentle
