" A Critical Revision' of the Genus Eucalyptus." — The 

 forty-third part of this monograph b\' Mr. J. H. ]\Taiden, I.S.O., 

 F.R.S., F.L.S., Government Botanist of New Soutli Wales and 

 Director of the Botanic Gardens, Sydney, is a particularly 

 interesting number, containing as it docs descriptions and 

 notes of three eucalypts which are well known to all lovers of 

 that group of trees. Everyone is familiar with /:. ficifolia, 

 F. V. M., the Scarlet Gum of Western Australia, wliich has 

 been so freelv used as a park tree throughout \'ictoria. Being 

 so familiar wjth it here, one naturally supposes it to be of 

 frequent occurrence in the West, but that is not so ; its habitat 

 appears to be limited, being scattered over an area of about 

 thirty-five miles by five in the vicinity of Brooke's Inlet, near 

 Cape Leeuwin, the south-western extremity of Australia. 

 The largest patch in one locality is about 2,000 acres. Here 

 its character is very different to its growth in our parks. It 

 occurs as a stunted tree, in some places forming flat-topped, 

 impenetrable thickets 8 to 10 feet high, so intertwined that 

 to walk over their tops would appear easier than to fight one's 

 way through them. The species seems to be particularly 

 subject to variation, especially in the colour of the flowers, 

 and also to hybridization, and requires further investigation 

 from thCse points of view. The next species dealt with, E. 

 calophylla, R. Br., also well known in Victoria as a park tree, 

 is generally called in the West " Red Gum," from the amount 

 of gum— reallv kino — which it yields. It flowers freely, and 

 is a good " bee tree." It has an extensive range in Western 

 Australia, and forms a handsome tree. It normally has white 

 flowers, but a variety, " rosea'' has been established by 

 nurserymen. The third species is E. cilriodora, or, rather, /:. 

 maciilata, Hook., var. cilriodora, F. v M., the Lemon-scented Gum 

 of Queensland, originally recorded from Balmy {sic) Creek, about 

 30 miles west of Springsure, where it was collected by Major 

 Mitchell and named by Sir W. Hooker, in the absence of 

 flowers or fruits, on account of its fragrant smell. The tree 

 has since been found to have an extensive range in Queensland 

 and New South Wales, the intensity of its fragrance varying 

 with different localities. Mr. Maiden considers it a true variety 

 of E. maciilala. the Spotted (ium of New South Wales and 

 Queensland. In Victoria there seems to be considerable 

 difference in the growth of the two trees as cultivated speci- 

 mens.
