EUCALYPTUS CLAVIGERA. 



few geographic journeys through the sandy and waterless regions, in which they often constitute a 

 considerable proiJortion of the vegetation, and where their general , monotony of forms is apt to 

 conceal the variety of their specific types to hurriedly passing and perhaps harassed travellers. 

 It is fair to assume, that some of these dwarf Eucalypts are likely to prove identical with extra- 

 tropical congeners, inasmuch as already in 1856 I traced a considerable number of the desert-shrubs 

 of the regions, pertaining to the Murray-Eiver and its tributaries, as far as 20° north latitude. 



Among the timber-trees of North-Australia E. rostrata is one of the tallest and the most 

 valuable ; but none of the species reach there the gigantic dimensions of several of their southern 

 congeners, unless E. Abergiana, E. Torelliana and possibly a few others on the literal slopes 

 of the Dividing Range in North-Queensland, where the jungles have as yet been but very 

 imperfectly traversed. The following are the species, which hitherto became known from North- 

 Australia : — Eucalyptus Abergiana, E. alba, E. aspera, E. brachyandra, E. clavigera, E. Cloeziana, 

 E. crebra, E. dichromophloia, E. exserta, E. ferruginea, E. grandifolia, E. latifolia, E. lej)tophleba, 

 E. maculata, E. melanophloia, E. microtheca, E. miniata, E. odontocarpa, E.' oligantha, E. pachy- 

 phylla, B. pallidifolia, B. patellaris, E. perfoliata, E. phcenicea, E. platyphylla, E. populifolia, 

 E. pruinosa, E. ptychocarpa, B. resinifera, B. rostrata, E. setosa, E. tereticornis, B. terminalis, 

 B. tesselaris, E. tetrodonta, B. Torelliana. The sections Eenantherffi and Hemiantheras are, as 

 far as hitherto known, not represented in North-Australia.
