J . G. H. KOSTERMANS ABSTRACT An illustrated description of the new monotypic genus 1 myristicoidee is presented, and its similarity to Beilsehmiedia, • and Endia-ndra is discussed.

Species nnicum. This remarkable plant looks at first sight like an Endiandra or a Beilschmiedia, because of its very conspicuous prominent leaf reticulation and the small pustules on midrib and branchlets; the loaves, however, are not opposite {as in mostBeilschmiedia) and the flower tube is Lurceolate reminding: that of Cryptocarya, although the orifice is much wider than that in Cryptocarya. The most remarkable feature are the 3 well developed, fleshy outer epals, as compared with the inconspicuous membraneous inner ones. The flower reminds strongly that of Myristicaceae. The number of fertile stamens is 3, which characteristic it shares with Endiandra but the deep urceolate tube does not occur in Endiandra, heither the discrepancy in the size and texture of the tepals. The flowers are too immature to ascertain the shape of the fruit cup, although it seems that the fruit might have a deep cup.

Arbor, ramulis glabris nitidis minute pustulatis, foliis alternantibus glabris subcoriaceis ellipticis vel subovato-elliptieis acutis, basi breve acutis, utrinque nitida perconspicue prominente sat laxe prominulo Reticulata, costis gracilis arcuatis, prominulis, paniculis subaxillaris foliis brevioribus multifloris axis ultimus laxe minuteque puberulis exeeptis glabris, floribus pedicellatis bracteolatis, tubus urceolatis, tepalibus tres exterioribus crassis depresso-ovati8 subacuminatis, tres interioribua minutis membranaceis, antheria rectangularis magnis bi-cellulatis, cellulis lateralis, filamentis glandulis basalibus extrorsis minutis munitia, ovario subovoidea glabra, stylo crasso subbrevioribus, stigmate inconapicuis. TYPUS: E. Wright S. 29265 (L) Tree, 25 m high, diameter 50 cm; branchlets glabrous, gloasy, reddish brown (in sicco), the youngest ones minutely pustular. Leaves spirally aaranged, subcoriaceous, glabrous, subovate-elliptic, 6 x 17—8 x 23 cm, acutish, base shortly acute; both surfaces glossy and conspicuously, rather laxly, prominently reticulate, lateral nerves 7—8 pairs, erect-patent, arcuate, slender, prominent on both surfaces, midrib prominulous in upper, rominent and pustular on the lower leaf surface; in between the lateral nerves strong parallel nerves, which do not reach the margin. Petiole 10—15 mm long, somewhat concave above. Panicles sub-axillary, up to 14 cm long, many-flowered, glabrous, except the very short, minutely, laxly rusty pilose ultimate branches; main peduncle strong, swollen at its base. Pedicels (immature) short, subtended by a minute bracteole. Tube sub-urceolate, (immature) 1—5 mm long; outer tepals stiff, broader than long, acuminulate; inner ones very thin, transparent, almost as high as the tepals, acuminate; anthers rectangular, large, with 2 large lateral cells, filaments short (immature) with tiny, sessile, basal glands; ovary avoid to ovoid-globose, style slightly shorter, rather thick, tapering, stigma inconspicuous. Drs. P. Baas, Rijksherbarium, Leiden, Netherlands, kindly undertook a precursory investigation of the anatomy of leaf and branchlets. His results are as follow: Leaf: Petiole with one strongly incurved to almost cylindrical vascular bundle. Stomata paracytic. Oil cells in mesophyl. Branchlets: Pericycle a composite sclerenehymatous cylinder of which. the stone cells have U-shaped wall thickenings. Vessel perforations simple; intervessel pits alternate; vessel ray pits large, simple. Axial xylem parenchyma paratracheal. BORNEO. Sarawak, 4th Div..
