THE GENUS EUCALYPTUS. 235 



fully developed, it measures more than three quarters of an inch 

 in length, and two-thirds of an inch in diameter, being four-celled, 

 with the valves not protruding beyond the broad oblique rim. 

 The volatile oil of the leaves possesses remarkable properties, but 

 the wood is not much esteemed, excepting for firewood. It is 

 sometimes split for fencing, and rough carpenter's work, although 

 the timber is by no means durable. Sir William Macarthur 

 states that the Woollybut of Illawarra is in very high repute for 

 wheelwright's work, and Dr. F. Mueller, in referring to the same 

 species in Q-ippsland, not only confirms the previous statement, 

 but says that it has a high character for durability when used for 

 fencing purposes. The differenca of the wood may probably 

 arise from some peculiarity of the soil. It is stated that the fibre 

 of the bark is adapted for packing paper. 



(8.) E. diversifolia. I have ventured to separate the " Camden 

 Woollybut" from "the Manna G-um" (E. viminalis), with which 

 it has been associated, because the trees differ so much from each 

 other in bark, habit, &c. The Camden Woollybut resembles in 

 some respects the Woollybut of other districts, having the lower 

 part of the tree covered with fibrous bark, and the upper branches 

 smooth. The inflorescence, however, and the leaves are very 

 different, being sometimes narrow-lanceolate and alternate, and 

 sometimes cordate or ovate-acuminate, sessile, and opposite. 

 The buds and seed-vessels are small, generally eight in each 

 axillary or lateral umbel. This species is common in the neigh- 

 bourhood of Berrima, and attains the height of 80 feet, but 

 beautiful as the form of the tree is, the wood is said to be 

 indifferent. 



(9.) E. ohosa is a shrub or small tree, the bark of the trunk 

 rough and persistent, that of the branches smooth, (JF. Mueller*). 

 It occurs principally in the desert of the Murray, and forms a 

 considerable portion of what is termed the " Mallee Scrub." 

 This species bears some resemblance to E. dumosa, but according 

 to Mr. Bentham, it is well distinguished by the longer pedicels, 

 the shape of the calyx, the thinner operculum, and the shape of 

 the fruit. 



The section of the Rhytipliloice, or the trees with wrinkled, 

 furrowed, and persistent bark, comprises the following species :. 

 (1.) E. microcorys; (2.) E. polyanihemos ; (3.) E. pulverulenta ;
