Gunn has addressed some botanical letters from Van 

 Diemen's Land to the editor of the ' London Journal of 

 Botany' (1844, pp. 485-96). He describes an excursion 

 to the western highlands of the island, and gives state- 

 ments of the localities of rare plants, with a more detailed 

 report upon a new species of Eucalyptus (E. Gunnii) 

 (Hooker, //.), which in December and January contains 

 a large quantity of a saccharine and fermentable juice, 

 whence it is called by the colonists the cider-tree. As it 

 forms extensive mountain-forests, it will probably here- 

 after become an important product of Tasmania. Harvey 

 has described some new Alyce from Van Diemen's Land 

 (id. pp. 407, 428) ; amongst them the Rhodomeleaceous 

 plant, Pollexfenia, which is also indigenous to the Cape. 

 Contributions to the Flora of New Zealand : Catalogue 

 of a Collection of Plants from New Zealand, by Stephen- 

 son, determined by J. D. Hooker (Lond, Journ. Bot., 

 1844, pp. 411-18) it contains but few new species; 

 Hepaticse Novse Zeelandiae et Tasmaniae, by J. D. 

 Hooker and Taylor (id. pp. 556-82) ; Diagnoses of New 

 Zealand Plants, by Raoul, preliminary to his illustrated 

 work, which was published in 1846 (Ann. Sc. Nat., 

 1844, ii, pp. 113-23), with the new genera: Ileodictyon 

 (Fungi), Pukafaria (Corneacese ?), and Tctrapalhea 

 (Passifloreae) .
