DISTRIBUTION AND ECOLOGY. — Diospyros squamosa is widely distributed in humid to subhumid forest, from Fort Dauphin to N of Sambava and in the NW from the Ampasindava peninsula to Nossi Be (Madagascar Catalogue 2020). It occurs from sea level to 1400 m elevation.
PHENOLOGY. — Flowering material has been collected in all months except May, July, November and January; fruiting has been recorded throughout the year.
VERNACULAR NAMES. — Hazojoby (Rasoanaivo 37, Tahinarivony 702), Hazomafana (Service Forestier 2980, 12980), Hazomainty (Service Forestier 4147, 10102, 12932, 13941), Korofoka (Ramison 122), Maintipototra (Cours 3225; Réserves Naturelles 5717, 11959), Maintiampototra (Rakotonirina 51), Torofoky (Réserves Naturelles 100056).
CONSERVATION STATUS. — Diospyros squamosa has a geographic range in the form of an EOO of 230 164 km 2 and a minimum AOO of 376 km 2. It is present in numerous protected areas (Ampasindava, Analalava, Andohahela, Lokobe, Makira, Mandena, Manombo, Marojejy, Masoala, Nosy Mangabe, Sainte Luce, Tampolo, and Vohibe), and exists at over 60 locations with respect to the principal threat of forest clearing for agriculture. Diospyros squamosa can therefore be assessed for its risk of extinction as Least Concern [LC] (IUCN 2012).
NOTES
Diospyros squamosa can be recognized from other members of the Squamosa group by its glabrous twigs, ovate to narrowly ovate leaves with the base decurrent along the petiole, sessile male flowers borne in triads, strongly revolute fruiting calyx, and glabrescent fruit that is often glaucous. In the southeastern portion of its range, D. squamosa often exhibits much smaller leaves. Diospyros bernieri and D. conifera are here placed in synonymy under D. squamosa; the type of the former (Bernier 113) from “forêt de Tintingue” along the East coast exhibits leaves and fruit identical to D. squamosa, whereas the type of the latter (Boivin 2108/2B) from Lokobe on Nosy Be also exhibits leaves identical to those of D. squamosa as well as the characteristic bracts surrounding the sessile male flowers.
