IX XXVII. E. Pimpiniana Maiden. 



See Part XV, with figs. 2 and 2b, Plate 72. 



Some specimens collected at Immana, near Ooldea, South Australia, by Prof. J. B. 

 Cleland, August, 1922, and figured at fig. 2c, Plate 281, throw light on this imperfectly 

 known species. It will be seen that the leaves may be larger than those depicted in 

 Plate 72. Buds are now available which, though not quite in the bursting stage, have 

 sub -cylindrical calyx -tubes of about 1 cm. long, capped with a bluntly pointed attenuated 

 operculum of about equal length. The base of the operculum slightly exceeds that of 

 the calyx-tube. The decumbent umbels are up to nine in the head, when not perfectly 

 ripe slightly urceolate and gradually tapering into the peduncle; when riper less 

 urceolate, and with the staminal ring indurate and well-marked, after the fashion of 

 E. eremophloia. The tips of the valves well sunk. 



AFFINITY. 



As compared with E. Isingiana (see Plate 235, Part LVI1), E. Isingiana has 

 campanulate fruits (not cylindrical ones) when young, and when mature, broad pyriform 

 and not cylindrical as those of E. Pimpiniana. 



Were it not for the slight difference in the shape of the fruits, both species would 

 appear to be conspecific on the present evidence, and my advice to local botanists is 

 to complete the material and the evidence.
