RUMPHIUS'S HERBARIUM AMBOINENSE 



base and relatively somewhat broader and thicker. Even if 

 eventually distinguished as a valid species, it must certainly be 

 placed near the Javanese one. 



EUGENIA RUM PHI I sp. nov. § Syzygium. 



Arbor rubra III Rumph. Herb. Amb. 3: 76. 



Amboina, Hitoe messen, Robinson PL Rumph. Amb. 199 (type), 200, 

 November 6, 1913, in forests, altitude about 175 meters, locally known as 

 kayu mera. 



Arbor glabra circiter 16 m alta, ramis ramulisque teretibus 

 vel ramulis obscure rotundato-angulatis ; foliis obovatis ad 

 obovato-ellipticis, usque ad 10 cm longis, apice latissime rotun- 

 datis interdum retusis vel obscurissime apiculatis, basi angus- 

 tatis, cuneatis, margine revolutis, supra olivaceis, valde nitidis, 

 subtus pallidis, haud puncticulatis, nervis utrinque numerosis, 

 tenuibus; inflorescentiis corymbosis, terminalibus, circiter 5 cm 

 longis; floribus plerumque in triadibus dispositis, omnibus bre- 

 viter pedicellatis, calycis circiter 7 mm longis, anguste infundi- 

 buliformibus, subtruncatis, calyptra 5 mm diametro. 



An entirely glabrous tree about 16 m in height, the branches 

 and branchlets brownish, smooth, terete or sometimes with 

 obscure rounded angles. Leaves coriaceous, obovate to obovate- 

 elliptic, 5 to 10 cm long, 3 to 5.5 cm wide, apex broadly rounded, 

 often retuse, sometimes obscurely apiculate, base gradually nar- 

 rowed, cuneate, margins recurved, the upper surface dark-oliva- 

 ceous, strongly shining, the lower pale, dull, not puncticulate ; 

 lateral nerves numerous, slender, spreading, densely arranged, 

 the primary ones but little more prominent than the secondary, 

 reticulations obsolete or nearly so; petioles about 1 cm long. 

 Inflorescence terminal, corymbose, about 5 cm long and wide, 

 branches from the base, the branches ascending, the flowers 

 white, mostly in triads on the ultimate branchlets, all pedicelled, 

 the bracteoles broadly ovate, rounded, thick, about 1 mm long, 

 the pedicels stout, 2 to 3 mm long. Calyx narrowly funnel- 

 shaped, about 7 mm long, truncate or with obscure lobes. Ca- 

 lyptra 5 mm in diameter, broadly ovoid, rounded. Stamens 

 indefinite, 5 to 10 mm long. 



This is a sufficiently characteristic species, which I cannot 

 refer to any previously described form. It is readily recogniz- 

 able by its densely nerved, coriaceous, obovate to obovate-elliptic, 

 broadly rounded, shining leaves, these often retuse at the apex. 

 No previous attempt has been made to determine the status of 

 Arbor rubra III of Rumphius, other than Hasskarl's reduction 

 of it to the Myrtaceae; it is undoubtedly Eugenia rumphii.
