Toliara: Fort Dauphin, Cloisel 180 (BM not seen, P not seen); Vinanibe, 23.X.1932, Decary 10864 (P!, BM, PRE [PRE0602194-0] image seen, S [S10-10152] image seen, TAN [TAN000589] image seen); Cap Ivatra, s.d., fl., Decary 10912 (MO [MO- 5587081]!, P [P00624056]!, G [G00018420] image seen, L [L0010882] image seen); vallée moyenne du Mandrare près d’Anadabolava, mont Vohibaria, 800–810 m (sommet), XII.1933, buds, Humbert 12626 (P [P00624051]!); FortDauphin, July, Scott-Elliot 3041 (K [K000231499] image seen, P [P00624055]!). = Homalium humblotii Baill. in Bull. Mens. Soc. Linn. Paris. 1: 574. 1886. Holotypus: MADAGASCAR: “Madag. bor.”, s.d., fr., Humblot 582 (P [P00624054]!; isotype: K [K000231500] image seen, LD [LD1215854] image seen, TAN [TAN000243] image seen, US [US00114722] image seen). Tree to 10 m, 15 cm dbh, or shrub. Leaves elliptical to narrowly (broadly) elliptical (seldom to ovate or rarely lanceolate), (2–)2.5–6.5 × (0.9–) 1.1–3.6 cm; petiole (1.5–)2–4(–5) mm; margins crenate-serrulate to subentire, with glands round or slightly elongated; adaxial surface drying darker, usually greenish or grayish, abaxial surface pale to medium brown (greenish). Inflorescences 1.5–8 cm. Filaments 0.8–2.4 mm. Vernacular names and uses. – “Fotsivony” (Humbert 12626); “Hazofotsy” (Randriatafika & Ramisy 408, Randriatafika & Rabenantoandro 715, Ratovoson 1661); “Hazombahy” (Réserves Naturelles 1812, 2303); “Hazombarorona” (Cours 2801); “Hazombato” (Cours 1898, Gautier et al. 3120); “Hazombatofotsy” (Service Forestier 13711); “Hazombatry” (Réserves Naturelles 2401); “Hazondrena” (Réserves Naturelles 2272); “Laza laza madiniky” (Gautier & Derleth 2563); “Mampay” (Hong-Wa 21); “Marankoditra” (Ramison & Ramisa 110, Randriataf ika & Ramisy 263); “Nefinzaza” (Cloisel 199); “Taimboalavo” (Réserves Naturelles 8936, 10716, Service Forestier 26398); “Tsilastra” (Service Forestier 9979); “Tsivelonatavy” (Service Forestier 6440); “Zora” (Service Forestier 6085, 6396, 7415); “Zore” (Réserves Naturelles 1350). Wood of H. axillare subsp. delphinense is used for construction (Hong-Wa 21, Ratovoson 1661, Réserves Naturelles 1812, Service Forestier 26398) and manufacture of wooden objects (Réserves Naturelles 1350). Distribution, ecology and conservation status. – Homalium axillare subsp. delphinense as herein defined is widespread and its habitat is variable, ranging from littoral forest on sand to mid- or somewhat high-elevation humid forests on gneiss. As noted above, though there is regional variation in morphology, that variation is not entirely consistent with reported habitat or altitude. It is possible that two distinct infraspecific taxa exist within this subspecies, but means of consistently separating them have not been identified. Because of the numerous localities, several of them protected, the subspecies’ appropriate conservation status is “Least Concern” [LC]. Notes. – As noted above, this subspecies remains variable and possibly heterogeneous. Sleumer annotated Cloisel 199 (P) as the lectotype of H. microphyllum var. delphinense but failed to indicate this choice in print (SLEUMER, 1973). Duplicates of three syntypes at BM that are not available through JSTOR are reported based on statements by SLEUMER (1973). Selected material examined. – MADAGASCAR. Prov.
