EUCALYPTUS GONIOCALTX. 



very Bumerous, consisting of one or two rows of short cells. I find tliis in accordance with 

 observations by Dr. Josef Moeller. 



The leaves on young plants and on adventitious shoots exceed sometimes a foot in length. 

 Young seedlings have heartshaped- or oval-roundish opposite sessile leaves, often much paler 

 beneath than above, but their stem is not quadrangular. In rare instances the stalklets of the 

 flowers become somewhat elongated. I found the lid sometimes double, the outer one being 

 fugacious. The fruit occurs not rarely of double the size of that delineated on the plate. A pair 

 of connate bracts covers cap-like the very young flower-cluster. The specific name was derived 

 from the particularly angular calyx. 



E. goniocalyx diifers from E. albens (Miquel, in Nederl. Kruitk. Archiev iv. 138) in less 

 persistent darker more deeply wrinkled or fissurated bark, the not usually pale hue of the foliage, 

 mostly narrower leaves with thinner and less spreading veins, very compressed flowerstalks, umbels 

 •only exceptionally not all solitary, shorter and rather less pointed lid, somewhat larger and not 

 almost globular anthers with longer slits, more angular fruit not almost always 4-celled, nor the 

 valves so deeply inserted. 



It is separated from E. viminalis in the veins of the leaves less crowded and less divergent, in 

 ■strongly compressed stalks with usually more than three flowers, in the angular calyx with ujDwards 

 more gradually attenuated lid, longer tube of the calyx, the more elongated fruit not extended into 

 an emerging broad rim, valves not usually four in number nor as a rule fully exserted. 



From E. capitellata it recedes in its bark not being very fibrous, in usually less shining foliage, 

 leaves with finer veins, distinctly angular calyx, anthers rather obverse- than renate-heartshaped, 

 thus upwards but not downwards dilated, fruit-calyx more elongated and usually narrower with a 

 neither protruding nor convex rim, so that the valves cannot rise from the vertex. 



From E. botryoides it is discernible by its less extensively persistent bark, by leaves not 

 darker green above than beneath, with less numerous and less transverse veins and with a different 

 distribution of the stomata and by a more gradually acute lid, but it bears close resemblance to 

 E. botryoides in its head-like umbels on flat two-edged stalks and likewise much in the form as 

 weU as in the structure of the fruit, though the valves are not so often four and perhaps never five 

 in number and generally nearer the smnmit. 



This is one of the most deserving of Eucalypts for forest-culture.

 tudinal section of flowerbud ; 3 and 4, front- and back-view of a stamen ; 5, style with stigma ; 6, longitudinal 

 section of fruit ; 7 and 9, transverse section of young and old fruit ; 8, young fruit seen from above ; 10, seeds ; 

 11, embryo; 12 and 13, transverse section of wood; the two latter respectively 60 and 220 times magnified; the 

 other figures very moderately but variously enlarged.
