6. Dalbergia canescens (Elmer) Merr.

Dalbergia canescens (Elmer) Merr. (1923) 294; Sunarno & H.Ohashi (1997) 203. — Derris canescens Elmer (1919) 3087; Adema (2003b) 408. — Type: Elmer 17883 (BO, CAL, K, L L0475194, U), Philippines, Luzon, Laguna, Los Baños, Mt Maquiling, 1917.

Distribution — Malesia: Borneo (Sabah), Philippines (Luzon, Palawan).

Habitat & Ecology — Forests.Altitude up to 1000 m. Flowering: June, July, September; fruiting: September.

Note — The indumentum is scraggy, ± villous to pubescent or sericeous, with sinuous hairs from ± patent to ± appressed, rusty brown when dry. Young fruits have thinly puberulous stipes and sometimes some hairs at the valves. BNBFD 9202 (Keith) probably belongs here. Young flowers have calyces 2–2.5 mm long. Soejarto & Fernando 7479 is mostly similar to D. canescens . Most obvious differences are in the size of calyx and calyx teeth, however, this specimen is in fruit and the calyx is probably slightly larger than that of flowering specimens. PPI 1294 (Stone et al.) probably belongs here. However, this specimen has some hairs at the outside of the standard and some hairs at ovary and stipe.
