57-1. 



First Section, — It comprises all the Eucalypts whose capsule at maturity is more or less exsert 

 that is to say, exceeding by a half or a third of its length the tube or calycine receptacle with which it is, 

 closely welded in its lower part. To this section belong — 



E. Lehman iti. E. rosirala. 



E. cornvta. E, tereticorms, 



E. macrorrhyncha. E. imignis. 

 E. amplifolia. 



(Here follows the " Second Section,'' which is combined with the number of flowers in the umbels, 

 &c. See p. 21.) 



Then follow the simultaneous suggestions of Luehmann and Tate made in 

 papers in Report Aust. Assoc. Adv. Science, VII, pp. 523 and 544 respectively (1898), 

 and as neither makes any reference to Naudin's paper, it was doubtless unknown to 

 them. 



I again remind my readers that Naudin's paper deals only with the limited 

 number of species cultivated in France and Algeria. Luehmann's paper deals with 

 140 species, Tate's with 90. apparently mainly based on the figures in Mueller's 

 " Eucalyptographia." 



Luehmann. 1898. — Luehmann's paper is " A Short Dichotomous Key to the 

 hitherto known species of Eucalyptus." He says that his paper should be looked upon 

 as an " auxiltiary guide only, without any full descriptions, and is for this reason 

 submitted in the form of a Key. The primarily character chosen is that of the fruit- 

 valves, whether quite enclosed, or whether the points protrude beyond the rim, or 

 whether the top of the rim is convex with every part raised above the rim ; secondarily 

 the shape and size of the fruit are taken into consideration." In the above he 

 unconsciously follows Naudin. The paper, from its nature, will not bear abstracting; 

 it contains various useful hints. 140 species are dealt with, and characters associated 

 with the fruit taken in about a third of the species. 



Tate. 1898. — Prof. Ralph Tate gives " A Review of the characters available for 

 the classification of the Eucalypts, with a synopsis of the species based on a carpological 

 basis." See a note at Part I. p. 11 of the present work. Following are extracts from 

 the paper : — 



There is obviously the need of au organ which exhibits greater diversity of form and structure, 

 and admits of a greater number of combinations than is afforded by the anther, or indeed any single 

 structure as yet considered. The requirements seem to me to be best fulfilled by the fruit offering, for 

 the most part, microscopic characters, and the special advantage that it is nearly always possible to obtain 

 them, whilst the flowering season is of limited duration, and is not always of annual recurrence. At the 

 same time, the characteristics are readily interpreted, needing no special manipulation .... 



I would now review the nature and value of the component elements embraced by a carpological 

 scheme of classification : — ■ 



1. Shape of Fruit. — The shape to be described is that of a fully-ripe specimen, as immature states 

 may prove delusive when testing the carpological system. . . . Thus in E. pyriformis the calyx-tube, 

 on the fall of the operculum, is obconic, with a horizontal summit, but in the adult state it becomes biconic. 

 Again, E. cosmophylla ranges from ovoid-conic in the early stages to hemispheric when mature.
