THE GENUS EUCALYPTUS. 241 



" Stringy Bark." E. dives occurs on the Blue Mountains, and 

 the Mittagong Bange. The leaves vary very much in shape and 

 size, being either sessile, opposite and cordate, or ovate-lanceolate, 

 on the same tree, whilst the seed-vessel is globose-truncate, about 

 two lines in diameter, four-celled, with a broad rim, and the cap- 

 sule sunk, the valves scarcely protruding. E. dives does not exceed 

 ten or twelve feet in height, and the wood is not esteemed. E. 

 piperita is a large tree growing near Sydney, on the Blue Moun- 

 tains, &c., &c., and the bark is fibrous and persistent, excepting 

 on the upper branches. The flower buds and seed-vessels are 

 small for so large a tree, the latter being somewhat of an ovoid 

 shape not exceeding three lines in diameter. This species yields 

 an agreeable volatile oil, though not to the same extent as the 

 "Woolly but (E. longifolia). The wood and bark are inferior to 

 those of the " Stringy Bark." 



(7.) E. stricta is a shrubby species with linear-lanceolate leaves 

 of a leathery texture, and the veins scarcely visible. It forms 

 brushes in the elevated parts of the Blue Mountains, and is the 

 E. micropliylla of Cunningham. 



To this section, the fibrous species mentioned under 12. Stuarti- 

 cma, must be added. It is a tree resembling the " Peppermint," 

 or the " Messmate," but called " Bastard Box," though differing 

 widely from the species more generally known by that name 

 amongst workmen, and not remarkable for the hardness of the 

 wood, The last section comprises those species which have the 

 bark hard, solid, and deeply furrowed. The following are enume- 

 rated by the learned authors of the Flora Australiensis : (1.) E. 

 leucoxylon', (2.) E. paniculata; (3.) E. crebra / (4<.) E. sideropJiloia; 

 and (5.) E. melanopJiloia. 



(1.) E. leucoxylon is the tree known as the " Bed-flowering," 

 or " Black Iron Bark," and although not so much esteemed as 

 two other species of " Iron Bark," it is nevertheless a very fine 

 tree, and exceedingly interesting from the colour of its flowers. 

 There has evidently been some misunderstanding respecting the 

 specific name, as it implies a tree with white wood, whereas the 

 species in question is remarkable for the dark colour of its wood. 

 It seems to me that E. leucoxylon was intended for some tree of 

 the Box kind, and that in all probability the Bed-flowering Iron 

 Bark should be referred to E. melliodora. I am led to this con-
