This tree deserves technologic attention, as a cosnietic oil might 

 distilled, from the foliage, the numerous oil-dots indicating a fair yield. 



Eugenia Baeuerlenii. — Branchlets somewhat angular; leaves on very 

 short stalks, thick-chartaceous, almost oblong-elliptical bluntly short- 

 acuminate, somewhat decurrent at the base very spreadingly penni- 

 nerved , copiously and pellucidly dotted , quite shining on both sides, 

 somewhat paler beneath ; cymes short, terminal ; peduncles and pedicels 

 angular; tne latter continuous with the calyx and as long or some- 

 what shorter; tube of the calyx almost semi-globular, wrinkled-striate, 

 extended beyond the ovary, hardly longer than the hemispheric smooth, 

 lid ; petals four, minute, orbicular, sessile, quite free ; anthers cordate- 

 roundish ; style slender ; stigma not dilated ; ovary two-celled, convex 

 at the summit; ovules several in each cell, covering and surrounding 

 the placentas. 



On the Strickland-River in New Guinea; W. Baeuerlen (Expe- 

 dition of the Australian Geographie Society). Height as far as noted 

 about 15 feet. Petioles less than half an inch long. Leaves measuring 

 3 — 4 inches in length, 1V2-2 inches in breadth; latei'al nerves rather 

 numerous; peripheric vein slightly waved, not far from the margin. 

 Primary peduncle 1/3 — 2/3 inch long; secondary peduncles mostly shorter, 

 with generally two or three flowers on the summit. Bracteoles minute, 

 almost deltoid , fugacious. Tube of the flowering calyx '/s — V^ inch 

 long, as well as the lid shining; the latter membranous, four-nerved, 

 not seceding into lobes. Petals only about 1/10 inch long, singly deci- 

 duous. Stamens pluriseriate , the longest measuring about V* inch ; 

 filaments pale. Placentas short, quite lateral. Fruit as yet unknown. 



This species approaches in many respects E. laevigata; but the 

 branchlets are distinctly angular the leaves longer, comparatively 

 narrower and almost suddenly protracted into the apex, their dots are 

 translucent, the calyx-tube is streaked, the petals are not cohering into 

 an operculum , the anthers more globular , and the fruit may also be 

 difFerent. 



The question is stiU open for discussion, whether that section of 

 Eugenia, which is characterised by an eucalyptoid calyx, should be 

 retained in the genus ; if so, then unavoidably Acicalyptus in its tota- 

 lity, comprising already three Polynesian, new also (with inclusion of 

 one of the two above descriued Eugenias) two Australian, several South- 

 Asiatic and at least one Papuan species, must merge into Eugenia; 

 but the genuine species of the latter genus hold precisely the same 

 relation to Acicalyptus, as Angophora to Eucalyptus. — Regretably the 

 name Acicalyptus , derived from an exceptional characteristic of the 

 original species discovered, does not apply to most of the other forms, 

 which must be considered congeneric. But it would appear, that Aci- 

 calyptus ought to be reduced to Cleistocalyx , published five years 

 earlier by Blume , though the calyptriform portion of the calyx , well 

 shown by his illustration (Mus. Bot. Lugd. LVD is according to his 

 description finally tearing into lobes. Closely cognate to this generic 

 group of plants are also Piliocalyx and to some extent Pleurocalyptus, 

 the latter as regards the dehiscence of its calyx being analogous to 

 that series of species of Eucalyptus, which have in E. terminalis a 

 leading representative. The fruit of Pleurocalyptus remained however 

 unknown, and may prove capsular; that of Piliocalyx agrees with the 

 generic characteristica of Acicalyptus, while the difference in the Posi- 

 tion of the ovules is rather sectional than generic. Some species of 

 Cleistocalyx became recorded under Syzygium ; but the typical form, 

 on which Gaertner (after Samuel Brown) founded that genas, is 

 S. caryophyllaeum ; it is therefore referable to Eugenia, and Syzygium 

 can thus not be so restricted, as to absorb Cleistocalyx, Acicalyptus 

 and Piliocalyx. The scattered leaves of Pleurocalyptus render it un- 

 likely, that its fruit will be that of an Eugenia or closely allied genus.]
