R E I N W A R D T I A [VOL. 7 7. C. LURIDA (Bl.) Copel. — Apart from the original collection, I have seen only one other, from West Java. In Sumatra and the Malay Pe- ninsula this species is found in ridge forest (not in exposed places) at 1250—1800 m. 8. C. GIGANTEA (Wall, ex Hook.) Holttum — In Java at low elevations, in the West only. This species' is very widely distributed, occurring in Ceylon and South India, from N.E. India to Burma, Thailand and Indochina to Penang and Kedah, also in central Sumatra. It grows in more open places than C. glabra. 9. C. GLABRA (Bl.) Copel. — In forest, to 1650 m, West Java; very few collections, and now apparently rare. In Borneo, Sumatra and the Malay Peninsula this species occurs in wet lowland forest, and in mountain forest to about 1500 m. 10. C. TRIPINNATA Copel. — Only two collections known from West Java, from forest at 700 m. This species occurs at altitudes of 250—1700 m throughout the Philippines, also in N. Borneo and Ambon; one collection has been made on Pulau Tioman, off the east coast of the Malay Peninsula. 11. C. TOMENTOSA (Bl.) Zoll. & Mar. — At 2200 m and above, in ridge forest and in open swampy places in gullies, on mountains from West Java to Flores. 12. C. PERSQUAMULIFERA (v.A.v.R.) Domin — On mountains, 1500— 2500 m, apparently in open places, few times collected; also in Central Sumatra. 13. C. TENGGERENSIS (Rosenst.)

The genus was proposed by Aublet, who gave a fairly good description, although his figure is bad and full of errors. Martius combined Moquilea, Couepia and Acioa in 1826 (Nov. Gen. et Sp. PL). Meissner (Genera) followed his example, giving Couepia and Acioa sectional rank. Zuccarini (Flora 1832), although still combining Mo- quilea and Couepia, believed that Acioa was a good genus. Endlicher includ- ed Acioa in Moquilea. Bentham (Benin. & Hk. f., Gen. PL), separated Couepia from Moquilea, but included Acioa in Couepia. Blume (1856) again included Acioa and Couepia as subgenera in Moquilea. Baillon (1869) considered Acioa a proper genus. He (Adansonia 1867) believed Griffonia to be congeneric with Acioa. Oliver (1871) pointed out the possibility of Acioa and Griffonia Hooker f., being congeneric. Focke (1891) maintained Acioa and this has been done since by other authors.

Branchlets glabrous, brown, with tiny, oblong lenticels. Leaves glabrous, coriaceous, subovate-elliptic (rarely lanceolate, 3 x 10 cm), 2.5—6 x 5—20 cm, base conspicuously decurrent and cuneate or rounded, apex shortly, bluntly acuminate, both surfaces densely, minutely, prominulously reti- culate and the veins marked by numerous, tiny, protruding dots, upper surface drying a dark colour, somewhat glossy, midrib prominulous; lower surface drying brown, less glossy, midrib prominent, lateral nerves 6—10 pairs, rather patent, towards margin strongly arcuate, slender, prominent.

Stipules relatively large, foliaceous, ovate, acute or acuminate, glabrous (except apex), 6—7 mm long, partly intrapetiolar, carinate, rather long- persistant.

Fruit subovoid, mono-locular, brown with scurvey dots and spots, laterally compressed, obtuse, up to 4 cm long and 3 cm in diameter; stalk 2 mm long and 2 mm in diam.; calyx more or less persistant. Exocarp 0.5 mm, mesocarp marbled, 2—3 mm, endocarp 0.5 mm; seedcoat redbrown, membranous, cotyledons 1.5 x 3 cm. DISTRIBUTION.—Malay Peninsula, Sumatra, Philippines (Mindanao), Borneo, Celebes, from sea level to 500 m alt. VERNAC. NAMES: Selemak (Central Sumatra); Tabena motea (Celebes, Malili region, Tobela, Padue language); Wua (= fruit) kote (Usu, Malili); Wua dira (Bugis language). USE: The fruit is edible and eaten in Celebes and Sumatra. The timber is easy to cut and saw, smells somewhat of HCN, is red when freshly cut, turns later brownred, rots away easily in the open. The one-celled ovary, the filaments which are grown together and the "papilionaceous" flower places this species in Acioa, although the tube is extremely short in comparison with American Acioa. It has no hairs ip the fruit cell and the cotyledons are flat-convex, contrary to Griffonia (= Acioa) of Africa. No glands were found on the leaves, but for some obscure, perhaps glandular tissue at the top of the petiole of leaves with a rounded leaf base. The number King's coll. 3745 is sometimes cited as 3715. • The description of the colour of the flower shows some discrepancies with different collectors; the petals are described as white, but in one case (Elmer) as yellow and he describes the calyx and bracts as having a dull flesh colour; elsewhere the flowers are described as being blue or violet. Glands could be observed in the material, formerly described as P. kunstleri and in P. heteropetalum, but they are often lacking, which is not uncommon in the genus. The scabrosity is found in all specimens. The petiole length varies between 5 and 10 mm. P. kunstleri was also described after a fruiting specimen. King diffe- rentiated it from P. heteropetalum by the subequal petals and straight flowers in the former as to the unequal and curved ones in the latter. 1965] A. J. G. H. KOSTERMANS: The genus Acioa 13 This observation may be attributed to the poor condition of the remnants of the flowers, in the fruiting specimens of P. kunstleri. King compared P. kunstleri with P. asperulum, to which it is certainly not allied.

His description of the fruit points to the variety wanji as described below. The inflorescence of the wild form of M. caesia is more condensed than that of the cultivated varieties; its fruit is very acid; when young it is green and partly dirty red. The two varieties kemanga and wanji differ only by the more elongate and open inflorescences and by the fruit, which are sweet acid and agree- able in taste, when they are fully ripe (fallen from the tree and left to ripen for another one or two days; the pulp becomes then very soft and juicy). Mangifera kemanga Blume is only grown in West Java as far as I know and perhaps in S. Sumatra and the Malay Peninsula.
