Myristica kalkmanii


Tree 15(-20) m. Leaves (thinly) chartaceous, oblong-lanceolate, 15-32 by 5-11 cm, base cuneate or (narrowly) rounded, apex acute-acuminate; Inflorescences between the lower leaves or Qust) below, of the Knema-type: Male and female flowers not seen. Fruits l(-3?) per infructescence, ± ellipsoid-fusiform, 3.5-4 by (2-) 2.5-3 cm, apex narrowly rounded or somewhat acute, base rounded or slightly narrowed, glabrescent, hairs mealy or powdery, rust-coloured, 0.3(-0.5) mm;


Asia-Tropical, Northern New Guinea present, Papua New Guinea present, SE Papua Barat present, W Sepik Prov present, Western Prov present, southern New Guinea present
Malesia: southern New Guinea (SE Papua Barat; Papua New Guinea: Western Prov.) and possibly (see note 2) northern New Guinea (W Sepik Prov.).


2 NGF 3931 (Womersley) (K, in fr.) from W Sepik probably belongs here; the specimen agrees with the material from southern New Guinea in twig structure, leaf shape, and fruits, but it differs in the non-papillose lower leaf surface. 1 Myristica kalkmanii is close to M. sulcata, with similar dark brown drying colour of the leaves. Myristica sulcata differs in its non-papillose lower leaf surface, thinly ridged (lined) or angular twigs, and subglobose fruits. Flowers of M. kalkmanii are not known. The species somewhat resembles M. ornata, with which it has the markedly papillose lower leaf surface in common, but M. ornata differs in its fainter nerves, stalked infructescences, and larger fruits.
