Naturalisation in Extra-Tropical Countries. 193 



This species, as well as E. odorata, E. foecunda and E. decipiens, 



thrives best in limestone-soil ; it likes a coast climate. Yields a 

 Mellitose-Manna . 



Eucalyptus goniocalyx, F. v. Mueller.* 



Generally known as Bastard-Boxtree and occasionally as Spotted 

 Gumtree. From Cape Otway to the Southern parts of New South 

 Wales, rare near St. Vincent's Gulf [McEwin] and Flinders Range 

 [J. E. Brown]. Ascends to 4,000 feet, and attains excep- 

 tionally a height of 250 feet. Thrives well near the city of 

 Algiers [Professor Bourlier]. Should be included among those 

 for Eucalyptus-plantations. Its wood resembles in many respects 

 that of E. globulus, and is, comparatively speaking, easily worked. 

 For house-building, fence-rails, and similar purposes it is extensively 

 employed in those forest-districts, where it is abundant, and has 

 proved a valuable timber. It is especially esteemed for wheel- 

 wrights' work [Falck]. Excellent for fuel. Our local experiments 

 showed the strength greater than that of E. amygdalina and E. 

 obliqua, but less than that of E. globulus. It varies considerably, 

 like many other Eucalypts, according to the situation of the trees. 

 Mellitose is formed occasionally on this tree and also on the following 

 species. In this species and others the author counted more than 

 one annual wood-ring without clearly visible demarcation of yearly 

 increment. 



Eucalyptus Gunnii, J. Hooker.* 



Known as Swamp- Gumtree, the mountain variety as Cider-tree. 

 Victoria, Tasmania and New South Wales, ascending alpine eleva- 

 tions. In the low-land along fertile valleys it attains a considerable 

 size, and supplies a strong useful timber. It is this species which 

 survived severe frosts at Kew-Gardens. Bees obtain unusually 

 much honey from the flowers of this species, it flowering earlier than 

 E. viminalis. Cattle and sheep browse on the foliage. Timber 

 found to be almost equal in strength to that of E. macrorrhyncha, 

 E. rostrata and E. globulus. The other very hardy Eucalypts com- 

 prise E. pauciflora, E. alpina, E. urnigera, E. coccifera and E. verni- 

 cosa, which all reach heights, covered with snow for several months 

 in the year. Succeeded well at Arran [Capt. Brown and Rev. D. 

 Landsborough], though slightly injured in its younger ramifications. 

 The percentage of kino-tannin in the absolutely dry bark is from 9^ 

 to 1 1 5 [ J. H. Maiden] . Any cutting down of healthy Eucalypts in 

 places of centres of populations, to substitute there for a zone of 

 evergreen vegetation the northern deciduous trees extensively, is 

 regrettable, as therewith the far superior hygienic value of the 

 Eucalypts is lost, and the aspect of the Australian landscape during 

 half a year rendered dismal, so far as vegetative features are con- 

 cerned.
