Manilkara zapota (L.) van Royen, Blumea 7:410. 1953.

DESCRIPTION (after van Royen).—Lactiferous tree. Leaves alternate, 5–12 × 1.8–5.5 cm, petioles slender, 1.5–3 cm; with 18–21 secondary nerves. Petals 0.3–0.6 cm, with 2 appendages. Stamens 6; anthers 0.15–3 mm. Ovary (6–)10–12-celled. Seeds compressed to terete with an almost basal scar; scar varying from large to small, wide to narrow, oblong to linear at base of the ventral side of seed;

RANGE.—Society Islands (cultivated): Tahiti: Pare, Mamao, not collected. Raiatea: Moore 722, Faaroa, alt. 20 m, 11 April 1927, sterile (BISH, 2 sheets; MIN).

Native to tropical America. Introduced into Tahiti in 1846 by Admiral Hamelin, according to Cuzent. Also cultivated in Hawaii, Rarotonga, Makatea, the Marquesas, and generally throughout the tropics.

ETHNOBOTANY.—English: sapodilla, or sapodilla plum; French: sapotille; both from the West Indian aboriginal name, sapota. Tahitian: tapoti, an obvious borrowing.

Used in America, but not in Tahiti, as a source of chicle, from which chewing-gum is made.

3. Plonchonella Pierre

Planchonella Pierre, Not. Bot. Sapot. 35. 1891.

This genus is a segregate from Sideroxylon, and was distributed among five sections of that genus by Engler. While it has not been fully adopted (rejected by Engler, Burkill, Drake, Rock, Merrill, Guillaumin, and F. B. H. Brown), many recent workers on Pacific floras have used it (Dubard, Lam, Skottsberg, Gillespie, St. John, and Chris-tophersen). We were not in a position to study the genus as a whole, but feel inclined to accept Dubard's and Lam's careful treatments.

TYPE-SPECIES.—Planchonella obovata R. Brown.

RANGE.—As a separate genus, it ranges from tropical Asia and Australia east to Tahiti, with about 82 species. Included with Sideroxylon (along with other segregates) it is found in the tropics and subtropics of both worlds with about 125 species. In either case, besides the following, there are endemic species in Hawaii (5), Samoa (1), and Fiji (2), and one which has been recorded from Fiji, Tonga, Rarotonga, and Makatea (P. grayana St. John, q.v. sub. P. tahitensis). Two of these have not been named in Sideroxylon and three have not been named in Planchonella, though all appear to be congeneric.

I. Planchonella tahitensis (Nadeaud) Pierre ex Dubard

Sideroxylon tahitense Nadeaud, Journ. de Bot. 11:111. 1897:Journ. de Bot. 13:3. 1899.

Planchonella tahitensis (Nadeaud) Pierre ex Dubard, Ann. Mus. Colon. Marseille 20:50. 1912 [name not in Kew Index].

DESCRIPTION (after Nadeaud).—Tree, 25–40 m high. Wood yellowish. Branches erect, whitish. Twigs and leaves whitish tomentose and buds reddish tomentose. Petioles 0.5–2.5 cm long. Blades ovate or obovate, 10–11 × 3–4 cm, irregularly decurrent, rounded or obtuse; coriaceous, often undulate, deep green with whitish border; lateral veins 10–12, prominent above. Flowers 4–7 in axillary fascicles. Pedicels 1–1.5 cm, arcuate, white-tomentose. Sepals 5, ovate, rounded, silky without, ciliate, persistent. Petals 5, exceeding the calyx, greenish white. Staminodes 5, small, narrow. Stamens 5, opposite the petals; anthers yellow. Ovary enlarged at base, 5-ribbed, tomentose, 5-celled, each 1-ovuled. Style short, stigma capitate, punctiform. Fruit pyriform, obovoid, 3-furrowed, 30 × 17–20 mm, apiculate. Seeds usually 3 (1–4), oboval, flattened, 21 × 10 × 6 mm, pointed and hooked at the base, thick and rounded on the back, with a raised ventral furrow, gray, red-spotted.

RANGE.—Society Islands, 500–1000 m. Flower 8 May 1896, and 25 April 1898. Nadeaud cites the following localities: Tahiti: Arue, Pirae; Papenoo, Haaripo; Faaa, Tipaerui; Punaauia, Punaruu. Moorea: Mt. Raairi.

We have not seen this. From Nadeaud's description, it differs from P. grayana St. John (St. John, in Wilder, 1934) only in being a larger tree with petioles averaging shorter, longer white-hairy pedicels, and seeds averaging larger. Grant saw eight collections of P. grayana (cited by St. John, in Wilder, 1934) from Makatea, Rarotonga, and Fiji (it has also been reported from Tonga). We suspect these two are conspecific but, of course, cannot consider combining them without having studied material of P. tahitensis. If such a union should eventually occur, however, Nadeaud's epithet would take precedence, so the nomenclature given here would not be affected. To the list of synonyms cited by St. John (in Wilder, 1934) may be added Bassia sp. (Cheeseman, 1903:286) and Sideroxylon vitiense Bonpland k Humboldt ex Drake (Drake del Castillo, 1892a:229). This combination thus appeared nine years before it was published by Burkill (1901); it is one of many of Drake del Castillo's names which have been overlooked by later workers on account of being buried in the addenda to the first supplement of the Kew Index.
