Dalbergia mimosella (Blanco) Prain (1904) 42;Merr.(1918) 184;(1923) 295; Sunarno & H.Ohashi (1996) 244; (1997) 211. — Amerimnon mimosella Blanco (1837) 563;(1845) 393;(1879) 358. — Neotype (here designated): PNH 28968 ( Ramos & Edaño) (L L0773264),Luzon,Prov.Tayabas,Umiray.

Dalbergia minahassae Koord.(1898) 430;(1922a) pl.15;(1922b) 9. — Type: Koorders 17701β (holo BO?; iso L L0773258 ), Celebes, Minahasa .

Dalbergia davaoensis Elmer (1910) 700. — Lectotype (here designated): Elmer 10551 (L L0773269 ; iso K, U), Mindanao, Distr. Davao, Todaya ( Mt Apo ).

Dalbergia lanceolaria auct. non L.f.: Llanos (1858) 502; Fern.-Vill. (in Naves & Fern.-Vill. 1880) 67, 103.

Distribution — Malesia: Singapore, Sumatra, Borneo, Philippines, Celebes.

Habitat & Ecology — Primary or secondary forests, disturbed riverine forest, river banks. Altitude 200–1200 m. Flowering: January, April to July, October to November; fruiting: May to September.

Uses — The wood is used as building material. The roots are used for handles of balos and other tools.

Notes — As far as we know there is no extant material of this species collected or seen by Blanco. Merrill (1918) did not collect a representative specimen.A neotype has been chosen collected on Luzon, the same general area from where Blanco described his Amerimnon mimosella . Koorders (1898) indicated a specimen he collected in the Minahasa in his original description of D. minahassae . Later on he gave the number of this collection as Koorders 17710β ( Koorders 1922b). Elmer (1913) gives a flowering and a fruiting specimen as ‘Type specimen’ of D. davaoensis ( Elmer 10551, 11925) suggesting that they came from the same tree. Elmer 10551, the flowering one, has been selected as the lectotype. Gray (1854) named a specimen collected by the U.S. Exploring Expedition ‘ Dalbergia cassioides Wall. ’, citing Bentham (1852) as a reference.According to Merrill (1923) this specimen belongs to D. mimosella . Neither Wallich nor Bentham (1852) described D. cassioides .

The stipules are early caducous. Specimens with very young leaves ( De Wilde & De Wilde-Duyfjes 12479, 13883, FB 27481, PNH 12142, 17734, PPI 18760) clearly show peltate stipules.
