522 ON EUCALYPTUS BICOLOR, A. CUNN., 



5. E. hcemastovia, Miq. 



16. Eucalyptus haemastoma, Smith, Act. Soc. Linn. Lond. iii. 285 DC. 

 Prodr. l.c. 219, n. 23.— E. largiflorens, Ferd. Miill. Herb. 



Locis humidis ad fl. Murray, fl. aestate (F.M. ). Van Diemensland (Stuart). 



Umbellge sub-5-floraB, nunc superne paniculato-confertse. Operculum 

 duplex; exterius depressum obsolete apiculatum, interius membranaceum 

 convexum muticum ; calycis tubus (p. 131) obconicus apice ampliatus hoc 

 paulum, illo duplo amplior, ambobus multo longior (ex Miill. adnot.)" 

 Nederl. Kruidk. Arch. iv. 130 (1856). 



This is B. bicolor, A. Cunn., "as to the Murray specimens " 

 (B.Fl. iii. 215). The Tasmanian (Van Diemen's Land) specimens 

 were probably £J. amygdalina. 



Affinities. 



a. With E. odorata, Behr. — Mueller (in ' Eucalyptographia ') 

 says E. odorata perhaps nearest approaches to E. largiflorens 

 (bicolor), which is best distinguished by its 



1. Usually narrow leaves of thinner consistence. 



2. With finer and rather more spreading veins. 



3. By the more extensively paniculated flowers. 



4. Of smaller size. 



5. By the shorter lid, often of less width than the tube of the 

 calyx. 



6. By the latter more suddenly meeting the stalklet. 



7. By smaller, more globular and less truncate anthers. 



8. By fruits of less size, with more contracted orifice and valves 

 close to the summit. 



This species runs into odorata and in extreme forms, and I 

 doubt if it is possible to separate them. Usually the leaves of 

 E. bicolor are dull-coloured, but this is not an infallible guide. 

 The fruits are usually smaller, sometimes much smaller, and more 

 cylindrical than those of E. odorata. The fruits of E. bicolor are 

 sub-cylindrical or ovoid, while those of odorata are hemispherical. 

 E. bicolor lias usually short filaments and blunt opercula. E. 

 bicolor is usually found on flats liable to floods; E. odorata prefers 

 drier situations.
