Garcinia keenania Pierre, Fl. Forest. Cochinch. Fasc. 5: 8. 1883; N.P. Singh in B. D.Sharma & Sanjappa (eds.), Fl. India 3: 114. 1993. Type: INDIA, Assam, Cachar, June 1874, R.L. Keenan 2672 (K [ K000677639 digital image!]).

Dioecious, evergreen shrubs or small trees; branchlets tetragonous. Petioles 0.5–1 cm long, adaxially ligulate at base; lamina elliptic-oblong, 7–11 × 2.8–5 cm, attenuate at base, margin entire, shortly acuminate at apex, acumen 0.5–1 cm long; midribs raised above and below; lateral veins more than 30 pairs per side, raised on both surfaces. Staminate flowers not known. Pistillate flowers tetramerous, 5–6, axillary fascicled, 0.5–0.7 cm in diam., pedicel c. 0.5 cm long; sepals orbicular, concave, 0.15–0.3 cm in diam.; petals orbicular or slightly oblong, white, 0.4–0.45 cm, concave; staminodes absent or sometimes minute; ovary globose, 0.4–0.5 cm in diam., 2-locular; stigma fleshy, convex, undulate on margin. Fruits not known.

Flowering & fruiting: Flowering from April to September; fruiting not known.

Habitat: No data available, hitherto known only from the type specimen.

Distribution: Endemic to India.

Notes: Pierre described the species based on a single specimen (Keenan 2672), which is a female flowering specimen and still remains not recollected. Maheshwari (1964) did not include this species in his revision on Indian Garcinia . Singh (1993) included it in the Flora of India. Though described from a single female specimen, it possesses characters to be treated as a distinct species, but could be confirmed only after collecting male and fruiting specimens. A thorough exploration of Cachar district in Assam is needed to find the species in the wild.
