MYRSINACEAE 



ARDISIA Swartz 

 ARDIS1A NIGROMACULATA sp. nov. § Akosmos. 



Frutex glaber, circiter 3 m alta; foliis numerosis, integris, 

 oblongo-ellipticis ad oblongo-obovatis, utrinque maculis nume- 

 rosis nigris conspicuis instructis, chartaceis vel subcoriaceis, 

 usque ad 8 cm longis, acuminatis, basi acutis, nervis primariis 

 utrinque circiter 10, tenuibus; inflorescentiis axillaribus, bipin- 

 natim paniculatis, multifloris, pedunculatis, foliis subaequan- 

 tibus; floribus 5-meris, calycis circiter 2.5 mm diametro, glan- 

 dulosis, lobis ovatis, rotundatis, margine leviter ciliatis, circiter 

 0.7 mm longis, petalis perspicue sed parce nigro-glandulosis, 

 circiter 3.5 mm longis. 



A glabrous shrub about 3 m high, the branches rather stout, 

 brown, 5 to 7 mm in diameter, the petiolar scars large, promi- 

 nent and rather crowded on the younger parts. Leaves num- 

 erous, rather crowded, oblong-elliptic to oblong-obovate, charta- 

 ceous to subcoriaceous, pale olivaceous-brown when dry, shining, 

 5 to 8 cm long, 2.5 to 4 cm wide, subequally narrowed to the 

 acute base and to the acuminate apex, the margins entire, both 

 surfaces with numerous, conspicuous, black or nearly black 

 maculae and minutely glandular-punctate ; primary lateral nerves 

 about 10 on each side of the midrib, slender, scarcely more pro- 

 minent than are the secondary nerves and reticulations ; petioles 



1 to 1.5 cm long. Inflorescences axillary and from the axils of 

 fallen leaves, bipinnately paniculate, peduncled, about as long 

 as the leaves, the primary branches 2.5 cm long or less. Flowers 

 numerous, racemosely arranged on the primary branches, 5- 

 merous, white, in full anthesis 8 mm in diameter, their pedicels 



2 mm long or less, the buds ovoid, acute, the styles not project- 

 ing. Calyx 2.5 mm in diameter, the lobes broadly ovate, rounded, 

 margins minutely ciliate, rather prominently glandular. Corolla- 

 lobes subelliptic, 3.5 mm long, obtuse, each with from 5 to 11 

 very prominent, nearly black glands. Anthers oblong-ovate, 

 acute, 2 mm long, the filaments distinct, short, the connective 

 obscurely glandular on the back. Ovary ovoid; style 2 mm 

 long, not projecting beyond the corolla in bud. 



Luzon, Tayabas Province, Mount Binuang, Bur. Sci. 28478 Ramos & 

 Edafw, May 7, 1917, in the mossy forest, altitude apparently about 1,000 

 meters. A specimen with immature flowers and somewhat larger, less 

 conspicuously maculate leaves, Bur. Sci. 28659 Ramos & Edano, from the 

 same locality, apparently represents the same species.
