EUCALYPTUS OBCOEDATA. 



rich vegetation around him, I have preferred Turczaninow's appellation, as Hooker's clashed to 

 some extent with that of E. platypodos of Cavanilles and is applicable to many species, although 

 the specific name adapted by the Moscow phytographer does not apply to all the forms of this 

 rather variable plant, but it is very expressive of the unusual shape of the leaves. Hooker 

 described the filaments as sulphur-yellow, and this discrepancy from the plant, defined by me in 

 1863 as E. nutans (together with some other slight differences) led me to regard E. nutans then 

 as a distinct species. 



In the small section of Orthostemone*, to which E. obcordata belongs, it is readily enough 

 distinguished by the form of its leaves, although we may not be fully aware of the variability 

 displayed by them. From E. cornuta it differs chiefly besides in foliage also in lesser height, in 

 the broader and longer flowerstalks, generally shorter lids, color of filaments, very angular fruits 

 and short valves ; but a variety is depictured on the plate of E. obcordata, which approaches in 

 the form of the calyces rather closely E. cornuta. The differences, by which this species is 

 separated from E. occidentalis, consists again in the broadness of the leaves and very angular 

 fruit-calyces, further in the absence of well-developed stalklets of the flowers, larger and particu- 

 larly wider fruits on still longer and broader stalks. 



The red-flowered variety of E. obcordata has some claims for admission into ornamental 

 shrubberies on account of the coloration of its filaments. It would form also excellent shelter- 

 copses and could be grown on poor soil and in an arid cHme. Bentham records having seen in 

 E. Brown's collection an Eucalyptus in very young bud and fruit from Goose-Island-Bay, seem- 

 ingly referable to E. obcordata, though the leaves were ovate-lanceolar.

 unexpanded flower ; 3 and 4, front- and back-view of an anther, with portion of its filament ; 5, style and stigma ; 

 6, longitudinal section of a fruit ; 7, transverse section of two fruits ; 8 and 9, fertile and sterile seeds ; 10, portion 

 of a leaf; all magnified, but to various extent.
