550 ON EUCALYPTUS PULVERULENTA, SIMS, 



tan turn licuit proponere species," an unsatisfactory description 

 Avhich is given here because of the rarity of the work. 



Loddiges' figure is almost a facsimile of that of E. jndverulenta, 

 Sims, (Bot. Mag. t. 2087). 



In Herb. Oxon. there is a specimen " Eucal3^ptus cordata, 

 Loddiges culta." It is probably E. pulverulenta, Sims, an opinion 

 already expressed by Mueller in Eucalyptographia; at the same 

 time I do not think it would be possible from the material avail- 

 able, and in absence of notes on the bark, to say that it is not 

 the pulvigera form of E. cordata. 



Loddiges states that his plant was a native of Van Diemen's 

 Land; if this be correct (and a mistake can easily be made) it 

 cannot be E. pulverulenta, as that species has not yet been dis- 

 covered in Tasmania. Loddiges' plate was published in 1819, and 

 it is quite possible that the plant was raised from cordata (p2il- 

 vigera) seed collected by Allan Cunningham or Eraser in the 

 Expedition of 1817. It is also possible that the plant was raised 

 from seed of true pulcerulenta gathered in the County of Argyle 

 or Camden, N.S.W. The point can hardly be settled without 

 further evidence. 



a. E. perfoliata, Cult. Madeira (Mount Villa, July, 1837). 

 Coll. Dr. J. F. Lippold, ex herb. Prof. R. Graham in herb. Cant. 

 In young bud only. This seems to be E. pulverulenta, Sims. 



A specimen in leaf only in herb. Cant. (Miis. Martyn) bearing 

 the label " this more round-leaved than the other " has small, 

 nearly orbicular perfoliate leaves. It may be E. pulverulenta, 

 Sims. 



h. E. perfoliata, Desf., may be E. globidus (B.Fl. iii. 200). 



c. E. perfoliata, A. Cunn. MS., may be E. Stuartiaiia, F.v.M., 

 or E. Cambagei, Deane and Maiden (see p. 557). 



d. E. 2?erfoliat7is, Hort. Bot. Cantab. 6th April, 1834. J. S. 

 Henslow. In herb. Cant. In bud only. 



This is probably E. p)ulverulenta, Sims. At the same time it 

 may be the pulvigera form of E. cordata. 



E. cinerea, F.v.M. (B.Fl. iii. 239). Leaves opposite, sessile, 

 •cordate, ovate or ovate-lanceolate, obtuse or acute . . . with
