conical, ca. 0.5 mm long, base with minute brownish scales; male flowers pedicelled, pedicel 0.6–2.0 mm long, subglabrous; sepals ovate or deltoid, 0.7–1.0 mm long, 0.5–0.7 mm wide at base, pubescent abaxially, glabrous adaxially, margins shortly ciliate; petals absent; stamens 8, 0.6 mm long, filaments fleshy, thickened and compressed, glabrous, anthers small, ca. 0.16 mm long; disk lobes as in female flowers; pistil rudimentary, styles 4, subulate, ca. 0.4 mm long, 0.2 mm wide at base, pubescent. Fruit a drupe, broadly ellipsoid, 6–9 cm long, 4.0– 4.5 cm in diam., blunt at both ends, greenish to brownish, with irregularly purple stripes when dry. Seeds ellipsoid, ca. 5 cm long, 2 cm in diam.

Flowering and fruiting: —March–August.

Habitat and distribution: — In lowland forests mixed with Dipterocarpus and also found in lower montane forests; below 1200 m. Brunei; Indonesia (? N Kalimantan); Malaysia (Johor, Kedah, Kelantan, Malacca, Negeri Sembilan, Pahang, Perak, Sabah, Sarawak, Selangor, Trengganu ) ( Figure 28 ) .

Vernacular names: — Sireh sireh, Nipis kulit, peparah, sial meaun (Malay).

Taxonomic notes: — Ding Hou (1958) published Anisophyllea corneri with the epithet in honor of E. J. H. Corner, who left this tree plant as an unnamed species in his first edition of the book Wayside Trees of Malaya ( Corner 1940). Ding Hou (1958) did not compare this species with any other known species in this genus at that time, but its affinity with A. grandis can be inferred from Corner (1940, 1988). Anisophyllea corneri is different from A. grandis in the length of its large leaves and fruits and in the strip-colored and glabrous surface of its fruits. In addition, A. corneri has main longitudinal veins raised on both surfaces of large leaves while A. grandis has slightly impressed or flat main longitudinal veins. In the protologue of A. corneri, Ding Hou (1958: 478) indicated “Typus Corner S. F. 25927, Sing, Bo, Kep.” These specimens should be syntypes of A. corneri . Thus, Wong & Madani (1995: 19) unintentionally lectotypified this name by citing the material at SING at “ holotype ” and those at BO and KEP as “ isotypes ”. With more collections available, we now know that A. corneri is a very common tree widely distributed in Borneo and the Malay Peninsula.
