Dalbergia pseudobaronii [2] is a species of flowering plant in the legume family Fabaceae. It is endemic to Madagascar. [3] Its leaves are similar to those of Dalbergia baronii , which gave the species its name. [3] [4]

Description

Vegetative characters

Dalbergia pseudobaronii is a deciduous tree up to 25 m tall. The leaves are imparipinnate, 5–13 cm long, and have a hairy rachis. The 20–35 alternate leaflets are 0.5–2.3 cm long, mostly glabrous and glossy above, and densely pubescent beneath. The leaflets are coriaceous, with revolute margins, when dried on herbarium sheets. [3]

Generative characters

It forms terminal and axillary inflorescences that are paniculate and shorter than the subtending leaves. The flowers are white becoming yellowish, 4–5.5 mm long, and have a violin-shaped standard petal and pubescent gynoecium. The fruits are up to 12 cm long and 5 cm wide (among the largest in Malagasy Dalbergia ), and contain a single seed. The pericarp is "net-veined, thickened, corky and fissured over the seed". [3]

Similar species

Habitat and distribution

Dalbergia pseudobaronii occurs in the Diana and Sava regions in north Madagascar. [2] It is mainly found along rivers and streams [3] such as the Manajeba, Mahavavy or Manambato rivers. [2] Fruiting collections have been recorded up to an altitude of 300 m. [2]

Uses

It produces a high-quality timber that is locally used for cabinet making. [3]

Conservation status

The IUCN Red List lists Dalbergia pseudobaronii as vulnerable. [5] Habitat loss and selective logging have resulted in population reduction. [3]

Due to overexploitation and the risk of confusion with similar species, Dalbergia pseudobaronii and other Dalbergia species from Madagascar were listed in CITES Appendix II [6] in 2013, currently with a zero export quota. [7]

<i>Dalbergia melanoxylon</i> Species of plant

Dalbergia melanoxylon is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments and fine furniture. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates.

<i>Pachypodium baronii</i> Species of flowering plant

Pachypodium baronii, the Madagascar palm or bontaka, is a flowering plant in the family Apocynaceae. It has the habit of a robust shrub with a spherical or bottle-shaped trunk. It has several cylindrical branches at the top.

<i>Pterocarpus santalinus</i> Species of legume

Pterocarpus santalinus, with the common names red sanders, red saunders, Yerra Chandanam, Chenchandanam, red sandalwood, Rakta Chandana, and saunderswood, is a species of Pterocarpus endemic to the southern Eastern Ghats mountain range of South India. This tree is valued for the rich red colour of its wood. The wood is traditionally considered not aromatic. However, in recent years there has been a marked uptick in the use of red sandalwood as a component of incense, especially in the west. The tree is not to be confused with the aromatic Santalum sandalwood trees that grow natively in Southern India.
