Pistillate flowers in a short-branched thyrse, fully open flowers same as or slightly larger than staminate flowers; pedicel green, short and thick (slightly shorter and thicker than in staminate flowers), 4 - angular; sepals and petals same as or slightly larger than in staminate flowers; staminodes absent; pistil mushroom-shaped, ovary globose or subglobose, 2 – 3 mm diam., glabrous, 5 – 7 - locular; stigma sessile, convex, radiate, shallowly 5 – 7 - lobed, papillate. Fruits berries, green, turning bright yellow, when ripe, glabrous and glaucous, cut fruits with a sticky yellow exudate, globose or subglobose, 4.5 – 7 × 4.3 – 6.3 cm, sometimes oblique, asymmetrical, without or with a short, thick beak and concave at the apex, with 6 – 8 longitudinal sutures, pericarp fleshy, 0.7 – 1.2 cm thick; persistent stigma dark brown or blackish-brown, 2.5 – 4 mm diam., indistinctly lobed, papillate; persistent sepals 2 – 4.5 × 3 – 5.7 mm, larger than in flowering material; fruiting stalk short and thick, 3 – 4.5 mm long, 5 – 7 mm diam.

36AA5251A5FD56A489BFA5A8E66AFFAD.taxon	etymology	Etymology. The specific epithet of Garcinia sopsopia is derived from “ Sopsopiya Bengalensium ” (Buchanan-Hamilton 1826; Mabberley 1977). The specific epithet of G. paniculata is a Latin word meaning with a branched-racemose or cymose inflorescence (Gledhill 2002). However, from our examination of specimens, the staminate inflorescence of this species is a terminal, many-branched thyrses and the pistillate inflorescence is a terminal, short-branched thyrses. The specific epithet of G. mckeaniana honors James W. McKean, MD (1860 – 1949). He was an American doctor and missionary who pioneered leprosy work in Thailand, including the construction of the Chiang Mai Leprosarium in 1908. He began his work in Chiang Mai in 1889 and remained there for his entire missionary life, carrying out general medical and evangelical work (https: // leprosyhistory. org / database / person 99).	en	Ngernsaengsaruay, Chatchai, Chanton, Pichet, Boonthasak, Weereesa, Mianmit, Nittaya, Kaewgrajang, Tharnrat (2025): Taxonomic treatment on Garcinia sopsopia (Section Brindonia, Clusiaceae) in Thailand, with a new synonym and three lectotypifications of its synonyms.
