Mueller, Ferd., Baron von, Description of two new species of Eugenia. 

 (.Extra print from the Australasian Journal of Pharmacy. June. 1886.) 



[ICugenia Holtzei.— Branchlets terete ; leaves thinly chartaceous, 

 conspicuously stalked, almost ovate, bluntly acuminate, distantly subtle- 

 penninerved, copiously and pellucidly dotted, paler beneath; cymes 

 Compound , lateral , trichotomous , with slender ramifications ; flowers 

 small, one to three on the ultimate peduncles, these about as long as 

 the flowers or variously shorter or almost obliterated ; calyx jointed 

 with the last peduncles, its tube turbinate-semiglobular, much produced 

 beyond the ovary, entire at the margin, not angular, somewhat longer 

 than the depressed-hemispheric slightly pointed lid ; petals four, minute, 

 roundish, sessile, agglutinated to the lid : anthers almost oval ; style 

 very slender; stigma not dilated ; ovary two-celled, flat-topped; ovules 

 not numerous in each cell, horizontal or ascending. 



Near Port Darwin; Moritz Holtze. A good-sized tree, with 

 aromatically fragrant foliage. Petioles 1/2— ^Z* inch long. Leaves 

 measuring 2—4 inches in length, and li/u— 2 inches in breadth, slightly 

 decurrent at the base ; the peripheric vein somewhat distant from the 

 margin and irregularly diverging into veinlets, none of the veins parti- 

 cularly prominent. Cymes 2-4 inches long; the general peduncle one 

 inch or less in length, not angular. Bracteoles minute, lanceolar-deltoid, 

 fugacious. Tube of the flowering calyx 1/8— i/e inch long , shining ; 

 operculum paler, membranous, after secession often persistently adhering 

 yet on one point, faintly four-ncu-ved, not bursting into lobes. Petals 

 about i/'o mch long, not rendily separable, though really distinct. 

 Stamens forming several rows, the longest measuring noarly V* i"ch ; 

 filaments pale. Placentas towards the base lateral. Fruit not soen. 

 This species is evidently allied to E. Kalahiensis , ditferin^ in rather 

 longer petioles, in leaves more protracted at the summit, with thinner 

 less copious nervature and with the circumferential vein less near the 

 edge, in not distinctly pedicellate flowers and probably in its fruit 

 also.
