Samadera is a genus of four species of plants belonging to the family Simaroubaceae in the order Sapindales. Its range is from eastern Africa through tropical Asia to eastern Australia.[1]
Type species: Samadera indica Gaertn
Description
Plants in this genus are large or small trees with simple leaves. The flowers are bisexual, produced in axillary or terminal umbels. The calyces (collective name for the sepals) are small, 3-5 partite (divided into parts) and imbricate (overlapping each other). The 3-5 petals are much longer than the calyx, they are coriaceous (leather-like, stiff and tough) and imbricate. The flower disk is large, conical, with 8-10 stamens, including in the corolla, with a small scale at the base. The stigmas are acute and the ovules are solitary and pendulous. The fruit (or seed capsule) consists of 1-5 large dry compressed 1 seeded drupes (stone fruit), each with a narrow unilateral wing.[2][failed verification][3]
The species was later placed in the section Samadera of the Simaroubaceae by Hans Peter Nooteboom (1934–2022) in 1962 (published in 1963), as Quassia indica, along with Samadera harmandiana as Quassia harmandiana. Nooteboom had taken a very broad view of the genus QuassiaL. and included therein various genera including, HannoaPlanch., Odyendyea(Pierre) Engl., PierreodendronEngl., SamaderaGaertn., SimabaAubl. and SimaroubaAubl. .[5][6]
In 2007, DNA sequencing, and phylogenetic analyses was carried out on members of the Simaroubaceae family. It found that genus Samadera was a sister to Clade V and that genus Quassia was also a sister to Clade V but they had separate lineages. This suggested the splitting up of genera Quassia again, with all Nooteboom's synonyms listed above being resurrected as independent genera. This includes Samadera indicaGaertn. as the accepted name for Quassia indica. The ornamental Quassia amaraL., which is occasionally planted in Singapore, remains in genus Quassia.[7]
Genus Samadera is agreed name by various authors including Klaus Kubitzki,[8] Devecchi et al. 2018,[9] and Pirani et al. 2021.[10]
Samadera indica for example, occurs in lowland tropical forest and peat swamp forest. at an altitude of 200 m (660 ft) above sea level.[18]
While Samadera bidwillii is commonly found in Queensland, Australia within lowland rainforest often with species Araucaria cunninghamii or on the edges of rain-forests, but it can also be found in other forest types, such as open forest and woodland, it is commonly found in areas adjacent to both temporary and permanent watercourses. At an altitude of 510 m (1,670 ft) above sea level.[16]
Samadera bidwillii is listed in Australia as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 and vulnerable under the Queensland Nature Conservation Act 1992. Due to threats to its habitat, such as clearing as a result of a range of activities including agriculture, forestry, urban development and recreational activities. The spread of non-native species such as lantana (Lantana camara) and exotic grasses, including guinea grass (Megathyrsus maximus) and Rhodes grass (Chloris gayana), may also threaten populations of Samadera bidwillii.[16]
Uses
Some species such as Samadera indica are gathered from the wild and are used medicinally in local folk medicines and also used to produce insecticides.[19] The wood of the tree is used locally for example in the state of Sarawak in Malaysia, where it is used for making knife-handles.[18]
