Second Section. 



Paniculate species, that is to say, those in which the flowers arc in terminal panicles or corymbs — 

 " Uniform " tree, opposite-leaved — 



E. cinorea. 



" Uniform " trees, alternate-leaved — 



E. polyanthema. E. ei/riodora. 



E. Behriana. E. cahplnjlla. 



E. crebra. 



In considering Naudin's contributions to classification, it must be borne in mind 

 that they do not refer to all or most of the species known in his day, but to certain 

 cultivated forms, principally in France and Algiers. Although the number of species 

 is so small, and a few seem indeterminable to us, his observations are always valuable. 



(a) Peduncle. 



The descriptions of both peduncle and pedicel should be made from the full- 

 grown bud, but sometimes we have to be content with immature ones. During the 

 progress of the bud from immaturity, it is found that the length and rotundity or 

 flatness, as applied to both peduncle and pedicel, are usually variable. In E. 

 jyyriformis (Plates 75 and 76) the thick peduncles and pedicels are round, as if turned 

 in a lathe. 



Width of the Peduncle. — This is very variable, and sometimes we have anomalous 

 forms. For example, in E. tetraptera, Plate 94, we have a short, strap-shaped peduncle, 

 in outline almost continuous (but bulging out a little), with two opposite wings of the 

 diminishing calyx-tube, the intermediate wings forming a not very prominent ridge 

 along the middle of both sides of the flat portion of the peduncle. The peduncle ends 

 at the calyx-tube. In this species we have a case of a sessile fruit adnate to the 

 peduncle, but with a more or less defined line between the base of the fruit and the 

 top of the peduncle. As the bud or fruit develops, so does the peduncle, until it 

 reaches a length of about 4J cm. with a breadth nearly as great. (A further drawing 

 will be offered later.) In this species the peduncle is articulate on the leaf axis, and in 

 all the specimens examined by me it remains attached to the fruit, falling off with it. 



In E. Preissiana, Plate 78, we have another instance of a broad, winged peduncle, 

 but the wings are not decurrent along the calyx- tube. The sessile fruits are articulate 

 on this peduncle, which is articulate in the axis of the leaves. (Both buds and fruits 

 have been seen by me in threes). 



In E. tetragona the buds are in threes, the central one being considerably longer 

 than the lateral ones. The compressed quadrangular (oblong in section) pedicels are 

 precurrent, forming or terminating two acute teeth to the calyx-tube. The teeth 

 make their appearance in the young buds as soon as the bracts fall off.
