Type:— VIETNAM. Lam Dong: Bao Loc (Blao), 800 m, December 1959, Ky s.n. (with flowers) (holotype P) .

Trees 15–30 m tall, trunk straight; bark smooth. Leaves dimorphic; small leaves caducous, lanceolate, apex acuminate; large leaves petiolate, petiole 3–7 mm long, furrowed adaxially, glabrous; leaf blade lanceolate, 5–6 cm long, 1.5–2.5 cm wide, base obliquely acute, apex acuminate or caudate with tips to 1 cm long, subcoriaceous, glabrous on both surfaces; main longitudinal veins 3–4, arising from blade base, midrib straight and bold, impressed adaxially and raised abaxially, lateral main veins 2–3, close to margins (ca. 1 mm from margins) and one often disappearing into margin; transverse veins irregular, some from midrib very obvious and curved upward towards blade apex, conspicuously pinnate-like; veinlets reticulate, visible on both surfaces or sometimes obscure adaxially and slightly prominent abaxially. Inflorescence a supra-axillary spike, solitary or in 2–3 serials; rachis 2.0– 2.5 cm long, tomentose, with 4 decussate bracts at the base; bracts small, ovate, apex acute; flower buds small, ca. 1 mm in diam.; flowers polygamous, 4-merous, sessile, with male and bisexual flowers on same rachis; male flowers receptacle and ovary connate, ca. 1 mm long; sepals deltoid, to 1.5 mm long, margins ciliate, glabrous; petals (4)–5–(7)-laciniate to 1/3 above base, laciniae threadlike and thickened at apex; stamens 8, episepalous 4 slightly longer than epipetalous 4; bisexual flowers receptacle longer (to 3 mm long); sepals, petals and stamens similar to male flowers; styles 4, short, base thickened; Fruit a drupe, globose-ovoid, ca. 3.5 cm long, 3 cm in diam., indistinctly 4-sulcate, (immature fruits) with sepals persistent at apex.

Flowering and fruiting: —Flowering in December; fruiting in June.

Habitat and distribution: —In evergreen montane rain forests growing together with trees of Fagaceae and Lauraceae ; ca. 800 m. Vietnam (Lam Dong) ( Figure 97 ).

Vernacular names and local usage: —Vietnamese: Sroh; fruits edible.

Taxonomic notes: —With the pinnate-like transverse veins, Anisophyllea penninervata is similar to the Malay species A. griffithii , from which it distinguishes by its smaller-sized leaves and by its obviously laciniate petals ( Vidal 1961). It is also close to another Malaya species A. curtisii in the structure of flowers, but its relatively smaller leaves with pinnate-like venation are quite different ( Vidal 1961). We did not see the type specimen Ky s.n. (at P) and we are not sure whether it contains any duplicates. The descriptions follows the protologue.
