552 ON EUCALYPTtrS PULVERULENT A, SIMS, 



Nevertheless it is not always easy to separate E. 2)ulve7'ulenta 

 from E. cordaia on herbarium specimens alone. I have not seen 

 E. cordata with flowers in more than threes; in E. pulverulenta 

 this is not uncommon, particularly in the lanceolar form. 



The leaves of E. cordata from Tasmania are usually large, but 

 particularly from New South Wales localities they are frequently 

 as small as those of typical i:>ulverulenta. 



■ The leaves of E. j^ulveridenta are usually thinner than those of 

 E. cordata, but this is a character which must be employed with 

 caution. 



The crenulation of the leaves of E. cordata from New South 

 Wales localities is often absent or nearly so. 



The bark of E. pulverulenta is always fibrous, partaking more 

 or less of a Stringybark character; that of E. cordata is smooth 

 or ribbony. The E. pidvigera of Cunningham is identical with 

 E. cordata in regard to bark. 



There is a specimen (cultivated) ex hort. Kew, labelled E. pul- 

 verulenta, in Herb. Calcutta. It is in flower only. It is probably 

 correctly named, yet most of the cordate leaves are slightly 

 crenulated, a character regarded as belonging to E. cordata 

 rather than to E. pulveridenta. The twigs are quadrangular and 

 glandular, and much of the young foliage is lanceolate. 



No. 16862, J. S. Gamble, Sept. 1885, Wellington (6000ft.) 

 Nilghiris, Madras, is labelled E. pulverulenta, Sims, and may be 

 that species. But in the absence of ripe fruits or notes on the 

 bark it may be a western New South Wales form {jpulvigera) of 

 E. cordata. 



B. — E. pulverulenta and E. Risdoni. A specimen ex herb. 

 Paris, in herb. Barbey-Boissier, collected 1844, probably by 

 Yerreaux, is E. Bisdoni, Hook., although labelled E. pulverulenta. 

 There is no doubt that the shape of the leaves in the two species 

 is often very similar. 



C. — E. pulverulenta and E. globulus. E. pulverulenta, Link, 

 (Enumeratio, p. 31), is, according to Mueller (Eucalyptographia) 

 E. globulus, Labill., the confusion having undoubtedly arisen
