EUCALYPTUS PYRIFORMIS. 



inch long. Stigma depressed. Fruits probably heavier than those of any other species, 

 attaining a weight, when dry, of rather above two ounces ; the discal orifice only half the width 

 of the diameter of the whole fruit, which attains two inches ; length (height) of the calycine 

 portion of the fruit not more than that of the discal portion or not even quite as much. Placenta! 

 column pyramidal-semiovate. Fertile seeds generally 1^-lf lines long, with radiating angles 

 from the hilum ; sterile seeds very much narrower, though many of them not shorter. 



This Eucalyptus was described under three names by Turczaninow, it presenting such 

 differences of forms as to induce him to regard them of specific value, and I was myself misled 

 by aberrative states of this species to assume them to be distinct, E. erythrocalyx moreover being 

 described before I had access to Drummond's specimens, from the comparison of which the brief 

 definitions, given by the Moscow botanist, could only be understood with certainty. E. Youngiana 

 represents the variety with flowers devoid of stalklets and with very strongly ridged and short- 

 tubed calyces ; E. pruinosa of Turczaninow (not of Schauer) exhibits a variety, bearing smaller 

 flowers with obverse pyramidal sharply few-angled calyx-tube. Drummond's collection contains 

 unnumbered another state of this species, with broader short-stalked opposite leaves and solitary 

 flowers, which latter however are placed quite normally on a well developed stalk. 



The name, retained by Bentham and here now also for this species in its full scope, alludes 

 to the somewhat pear-like shape of the calyx. 



E. pyriformis is closely akin to E. macrocarpa, but any whitish bloom on it is confined to the 

 calyces and their stalks, the leaves are always narrower and gradually attenuated at the base, 

 only exceptionally opposite and even then obviously stalked, the flowers stand seldom singly and 

 are never absolutely sessile, the calyx has not an even surface, the upper portion of the fruit from 

 the edge of the calyx-tube to the rim of the disk is more elevated and at the summit more 

 contracted, reaching beyond the base of the valves. E. pachyphylla approaches the variety 

 pruinosa of E. pyriformis, but its flowers and fruits are much smaller, almost devoid of a general 

 flowerstalk and crowded to the number of about 7 together. The affinity to E. erythronema is 

 more remote. 



E. pyriformis has claims for ornamental culture, especially where in an arid clime garden- 

 copses are required.
