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.
