E. miniala. — Ellipsoid-oval, with dorsally broadisli connective. 



E. occidentalis. — Connective dorsally rather broad, glandular-turgid towards the summit beneath. 



E. Oldfieldii. — Anther-cells separated by the narrow but distinct connective. 



E. Preissiana. — Sub-terruinal gland of the anthers conspicuous. 



E. resinifera. — With a broad connective. 



E. sepulcralis. — Dorsal gland small, seated near the summit. 



E. tetraptera. — Terminated by a black-purple gland. 



E. uncinata.— Anthers with no glandular turgidity. 



In my descriptions of species I have given attention to the gland, invariably 

 describing it in recent years. At pp. 525 to 537, where a classification of anthers is 

 submitted, and also in the figures of individual species, the gland has been freely 

 employed, probably to a greater extent than by any previous author, but we are far 

 from finabty as to the morphology and classificatory value of these minute organs. 



E. GYNCECIUM. 



Ovary. 



The following are portions of generic descriptions referring to the ovary : — 



" Ovary inferior, the summit glabrous, flat, convex or conical, 3- to 6-celled, with numerous ovules 

 in each cell, in 2 to 4 rows, on an adnate or oblong and peltate axile placenta." (B. Fl. Ill, 185) .... 

 '' The number of cells of the ovary is also very rarely a guide to the species. They generally vary from 

 3 to 4 or from 4 to 5, very rarely 6, and not constantly so in any species I have seen. In E. pltcenicea 

 I have only seen two ; but as the specimens known are but few, and all probably gathered from one tree, 

 we have no means of judging whether the character is constant," (?'&., 188). (Mueller says constant, and 

 that is my experience. J.H.M.). 



" 3-6 celled, very rarely or quite exceptionally 2-celled ; its lower portion adnate ; its upper portion 

 more or less free." (Eucalyptographia.) 



" The ovary is never entirely free ; it is intimately fused to the calyx-tube or receptacle, sometimes 

 entirely, sometimes solely for a half or third of its length, the summit remaining free. It is surmounted 

 by a simple style, with a stigma pointed or a little dilated." (Naudin II, 13.) 



Top of the Ovary. 



Bentham is the only botanist who makes a point of referring to this character, 

 and, as will be seen, there is not much variation, the top usually being flat, and, to a 

 less extent, convex, and sometimes conical. 



[Mueller makes the following statement : — -" The insertion and form of the fruit 

 valves, which, before opening, form either a flat or more or less convex vertex to the 

 capsule, a character which, beautiful as it is, can only be studied in living plants." 

 (Hooker's Joum. Bot. ix, 165, 1857), and from the diagrams of longitudinal fruits in 

 'Eucalyptographia" (under E. Preissiana) the shape of the top of the ovary may 

 be seen in a number of species, but he does not refer to the character in the text. It 

 does not appear to be used by any botanist for the purpose of diagnosis.]
