The question of looking upon E. Lehmanni Preiss and E. annulata. Benth., as 

 species distinct from E. cornuta Labill., now arises. 



Bentliam, at least tentatively, kept cornuta and Lehmanni apart (also " several 

 of the following species.'" annulata — the others of the " several " are not specified), as 

 " I have not yet met with intermediates connecting the different forms, especially as 

 to the summit of the ovary and the fruit." 



In his charming figure in Bot. Mag. t. 6140, Hooker figures E. Lehmanni as 

 E. cornuta, and speaks of it as the " Yeit " (Yate), which is the name ordinarily applied 

 to E. cornuta. The specimen figured was a slender tree (sketch given) about 9 feet 

 high, with a smooth bark and spreading branches. 



" The only characteristic which distances E. Lehmanni from E. cornuta consists 

 in the concrescence of the calyx-tubes, but this coalescence is as much one of degrees in 

 this case, as in several instances similarly occurring in the genus Melaleuca ; and even 

 in quite normal forms of E. cornuta amongst the disunited fruits in the same cluster 

 some may be noticed connate." (Eucalyptographia.) 



Naudin, " Memoir sur les Eucalyptus " (1883), p. 410 (1st Mem.), says ■— " E. 

 Lehmanni is certainly one of the most distinct species of the whole genus, and it would 

 be difficult to confuse it with any other." 



In his 2nd Mem. (" Description et emploi des Eucalyptus," 1891) p. 25, he 

 continued to keep E. Lehmanni apart. 



Following is a translation of Diels and Pritzel's observations : — 

 " E. cornuta Labill. The definition of the geographical area given by Mueller seems doubtful to 

 us. Mueller seems to include E. Lehmanni and E. annulata in E. cornuta, although in the description of 

 the species he omits them; Maiden (in letters) lately expressed the same opinion. We, ourselves, thought 

 that the forms of E. Lehmanni and E. annulata were well defined. We have not seen the typical species, 

 except from Lake Muir towards King George's Sound. Aberrant dwarf forms, distinguished with broader 

 leaves, abound in the granite hills around King George's Sound." (Engler's Jahrb. xxxv, 441, 1905.) 



I have compiled, chiefly, from B.F1. iii, 195, but also from p. 233, the following 

 comparative table of E. Lehmanni, cornuta and annulata : —
