Dalbergia densa Benth. (1843) 217; (1852) 255; Miq. (1855) 123; Benth. (1860) 43; Prain (1904) 73,t. 53,54; Merr.(1923) 295;Verdc.(1979) 295. — Lectotype (here designated): Hinds s.n. (BM? n.v.; iso K), New Guinea.
Dalbergia densa Benth. var. typica Prain (1904) 73, t. 53, nom. illeg.
Dalbergia densa Benth. var. australis Prain (1904) View in CoL 73, t. 54. — Type: not indicated.
Distribution — Malesia: Philippines, Moluccas, New Guinea; N Australia.
Habitat & Ecology — Primary or secondary forests, in fringe vegetation, in sago palm swamp along rivers, in drier areas usually in woodland or eucalyptus savannah, Castanopsis - Auracaria forest. Altitude up to 1000 m. Flowering: February, March, June to Augustus; fruiting: March, October, November.
Uses — In the Philippines the bark is applied to relieve internal pains.
Notes — Bentham (1843) based his species on two specimens: Hinds s.n. and Barclay s.n. In 1860 he only cites the Hinds specimen. Verdcourt (1979) took this specimen for the type. Here we select Hinds s.n. as the lectotype.
Prain (1904) distinguished two varieties, one (‘ typica ’) with few, larger leaflets and hairy ovaries, one (‘ australis ’) with more, smaller leaflets and glabrous ovaries. In a note he remarks: “The specimens from German New Guinea are, however, very nearly intermediate between those of Australia and those of the Moluccas.” Bentham (1860) described the Australian specimens of D. densa in a similar way as he did when he described the species in 1843 and notes: “The Australian specimens have rather more leaflets than the New Guinea ones, but do not otherwise differ”. Verdcourt (1979) give both varieties of Prain for New Guinea with only the number and size of the leaflets as differences. In these characters there is a large overlap. Dalbergia densa is a rather variable species, especially in number and size of leaflets and in the indumentum of various organs: the upper surface of leaflets may be glabrous to rather densely sericeous, calyces may be glabrous or ciliate at the teeth or with few to several hairs mainly in the middle part of the teeth, ovaries and stipes are usually sericeous, but may be glabrous, pods are often glabrous, but may have some hairs at stipe and sutures. However, there is no constant combination of characters and specimens with larger leaflets occur here and there in the distribution range. It is better to see this taxon as a variable species and forget about the varieties.
