TYPUs: Sinclair S.F.N. 10274, (BO). Shrub, 120 cm high. Sap sulphur yellow. Branchlets with rather arge lenticels. Leaves biaeriate, coriaceous, elliptic, 10 x 50—12 x 31 cm, shortly, sharply acuminate, base rounded; upper surface subtmllate between the numerous (up to 30 pairs) of patent and sagging impressed lateral nerves, in between short impressed nerves, reticulation dense, prominulous, midrib broad, prominulous; lower surface pale green with yellowish tinge (fresh) with prominent midrib and filiform laterals, which anastomose 5—10 mm from the margin. Petiole 1—1.5 cm long, thickish; hypsophyls up to 1 cm long, ovate, caudate, stiff. Fruit orange, sessile in leaf axil, subglobose, radially atriate, fleshy, 3 cm diam. with 5 cells and 5 large seeds. The leaves are similar to those of M. anastomosans (Miq.) Kosterm., hut have much more lateral nerves and have a rounded base. Mammea anastomosans has cauliflorous flowers, the fruit are unknown. M. sinclairi has axiliar, sessile, plurilocellatc fruit and hence falls in subgenus Mammea.

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. Pertelaan bergambar marga coides disajikan dan persomaanny Cryptocarya serta Endiandra dibi nonotipe haru Triadodaphne tnyristi- i dengan ruarga-marga Beilschmiedia, Triadodaphne Kosterm., gen nov. Arbor foliis alternantibus floribus parvis tubua urceolatua tepalibus sterioribus crasais incurvis, interioribua rninutis membranaceis, stamini- us tres fertilibus tepalibus exterioribus oppositus, antheris bilocellatia amentis baai biglandulosis, ovario stylo diatincta, stigmate inconapicua uncata. 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. i C O N T E N T S • P a g e H A T T I N K , T. A.
