 SYNONYM. 



E. crehra, F.v.M., var. citrata, F.v.M. 



Fruit-bearing twigs of an Ironbark tree, with lemon-scented foliage, were obtained by Mr. Bailey on 

 the Palmer River ; these seem referable to E. crehra also, although the leaves are shorter and blunter, and 

 the peripheric vein is slightly removed from the edge ; the fragrance of this supposed variety, which might 

 be called citrata, is so exquisite that the leaves can be uspd as a culinary condiment. ("Eucalyptographia," 

 under E. crehra.) The idea of llavouriiitr food with a citrouella-like oil is amusing. 



RANGE. 



Its rang^e appears to be very limited, being confiDed to a not very extensive 

 area in Northern Queensland, chiefly on the Palmer llivcr (south-west of Cooktown). 

 Hence its seed is sought after as a commercially valuable oil-bearing Eucalyptus 

 tree for tropical countries. 



AFFINITIES. 



1. With E. crehra, F.v.M. 



The affinity is very close. The shape of the juvenile foliage and the odour of 

 the leaves separate them. There is no citral in E. crehra. The flowers and fruits of 

 H. Staigeriana are, generally speaking, coarser than those of E. crehra. The wood, 

 bark, and habit of the two trees are very similar. The fruit is sometimes conoid 

 and with a rounded rim, like that of E. crehra. 



2. With E. melanophloia, F.v.M. 



The affinity is even closer to the lanceolate-leaved form of this species than 

 with E. crehra. There is no citral in the leaves of E. melanophloia.
