11. LEIOPHLOM^-RHYTOPHLOIiE. 



vimincdis. 



[E. viminalis is normally a Smooth-bark, though never quite free JErom rough 

 bark at the butt. In some trees this rough bark extends a considerable distance along 

 the trunk. See Part XXVIII, p. 168.] 



12. Rhytiphlole-Inophloi^. 

 filularis. 

 [In my view, this is a member of the HemipMoicB. While there is some variation 

 in the bark, as indeed in so many others, I do not know of sufficient in this species to 

 admit it into the other groups mentioned.] 



13. Of the following species, Mueller did not know the nature of the bark, or 

 of that of some of them ; being such small species, he felt tmcertain : — 



stricta. angustissima. 



Oldfieldii. santalifolia. 



Todtiana. caesia. 



buprestium. gracilis. 



uncinaia. alba. 



gamopJiylla. brachyandra. 



incrassata. oleosa, 



cneorifolia. Foelschiana. 



vernicosa. pachypoda. 



erythronema. cosmophylla. 



alpina. Preissiana. 



pachyphylla. pyriformis. 



macrocarpa. tetraptera. 



odonfocarpa. eudesmioides . 



tetragona. erythrocorys. 



[Of many of them we can speak now as to their bark, and I have transferred 

 most to a practically natural group, dependent on habit — the Mallees or Marlocks. to 

 be dealt with below, p. 321.] 



ii'. Maiden, 1891. — In the "Educational Gazette of New South Wales" for 

 June, 1891, p. 4, in an article on " The Study of Eucal}^ts,"" I wrote as follows (only 

 New South Wales species were dealt ■n'ith) : — 



Because of the height of these trees, and their uncertain periods of flowering, our readiest method 

 of approximately distinguishing between them is bv means of tbsir barks. For this purpose we notic 

 two things :
