Pantadenia adenanthera is a shrub in the Euphorbiaceae family. It is found in parts of Southeast Asia. The species is used for its wood (high-quality house-posts, firewood) and edible fruit.
This species grows as a perennial shrub, between 0.4 and 2m tall, branching prolifically. [1] The species can be distinguished from other Euphorbiaceae in Thailand by the following traits: the inflorescences grow opposite the leaves; petals have apical glands; and the stamens also have an apical gland. [2] Flowering occurs from July to January, fruit appear from November to March, while leafing occurs from May to April. [3]
Growing in parts of Southeast Asia, the species is found in the following countries: Thailand, Cambodia, Laos, Vietnam. [4]
In Cambodia and southern Vietnam the shrub grows in secondary formations in the plains, and along rivers. [1]
The shrub grows along the Mekong river in Kratie and Steung Treng Provinces, Cambodia. [3] It is moderately abundant in the deciduous forest with bamboo formation and in degraded areas, on soils derived from metamorphic sandstone bedrock, at 25-30m altitude.
The plant is called: (voër) krâchâk ânndaëk (="turtle claw"), [1] or krâcâk [5] (Khmer) in Cambodia.
The fruit are edible, and the branches are used for firewood in Cambodia. [1]
Cambodian house-making carpenters value the hard, heavy and rot- and insect-proof, though not cheap, wood of this species as the raw material for the posts. [5] The posts are set in the ground and support the frame and floor. It is thought that the choice of quality wood will not only help the solidity of the house, but will increase the happiness of the resident family.
François Gagnepain (1866-1952), a long-lived and prolific French botanist described this species in the paper "Quelques genres nouveaux d'Euphorbiacées" in an issue of the Bulletin de la Société botanique de France published in 1925 (though dated 1924). [6] [7]

Sindora siamensis is a species of tree in the subfamily Detarioideae of the family Fabaceae. It has an accepted infraspecific, the variety S. siamensis var. maritima (Pierre) K.Larsen & S.S.Larsen. See taxon box to the right below, and below for details on the variety maritima. The nominate species is found in many countries in tropical Asia. Like several other species in the genus Sindora, its wood is considered valuable; the least concern conservation status may reflect efforts to replant this species, but mortality rates are high. As well as the wood, the plant provides raw material for chemical products, food and drink, and domestic utensils.

Achille Eugène Finet and François Gagnepain, the French botanists who first formally described the species, named it after Mt.
