Myrsine niauensis Fosberg & Sachet

Myrsine niauensis Fosberg & Sachet

Folia laminis oblongis supra minutissime punctatis infra papillatis, petiolis gracilibus 6–3 mm longis, venis 12–18 jugis obscuris; fructus globosus valde nigro-punctatus, calyce lobis 4, valde glanduloso-puberulis, pedicillo 2 mm longo 0.5 mm crasso.

Branchlets pale brownish straw-color, about 2.5 mm thick; leaves oblong, to 10 × 4.5 cm, rather stiff, subcoriaceous, densely but minutely black punctate on upper surface, only obscurely and sparsely so beneath, but sparsely papillate beneath, apices rounded, bases acute, main veins 12–18 on a side, uneven in strength, opposite to alternate, anastomosing into a strongly undulate submarginal vein 2–3 mm from margin, network rather obscure, venation not strong, about equally visible above and beneath, base rather abruptly decurrent into a rather slender petiole 6–8 (−10) mm long, about 1 mm thick; flower-bearing tubercles or inflorescences very reduced, 2 mm or less wide and high, scaly bractlets broadly triangular, strongly glandular-puberulent, glands reddish brown, pedicels slender, few, 2 or 3, about 2 mm long, 0.5 or less mm thick; fruiting calyx lobes 4, united in basal part, broadly ovate-obtuse to almost orbicular, glandular-puberulent, erose-ciliolate, obscurely dark dotted, fruit globose, 3–4 mm diameter strongly black-dotted.

Closely related to the new species M. adamsonii of the Marquesas, differing in the broader, more oblong leaves less punctate beneath, apices more rounded, petiole shorter, venation less prominent, fruits smaller, black-dotted, on longer and thinner pedicels, fruiting calyx strongly glandular-puberulent, pedicels less so.
