Spathiostemon moniliformis is a plant that can grow as a shrub or a tree in the Euphorbiaceae family, Acalypheae tribe. It is endemic to southern/peninsular Thailand.
The species grows as a shrub or tree, in height up to 10m, with a trunk diameter at breast height up to 11 cm. [1] [2] Leaves are rarely ovate tending usually to elliptic, some 6.2-26.5 x 2.3-9.5 cm in size, on both sides they are smooth and glabrous. Flowers are white to yellowish. The fruit is reddish to dark brown, smooth and glabrous, some 9 x 6mm in size. It flowers and fruits from December to March, August to September.
The species is distinguished from its sister taxa Spathiostemon javensis by the following traits: Glabrous petioles; the leaves do not have domatia; the inflorescences are glabrous, and the staminate inflorescences are from 6 to 28 cm long; the pistillate flowers have sepals in 2 whorls of 3; the ovary and fruit are smooth. [1]
The taxa is distinguished from other Euphorbiaceae growing in Thailand by having: elliptic leaves whose basal margin has 3 black dot-like glands on either side of the midrib; the petioles are both basally and apically pulvinate; seeds do not have arilloid. [3]
The shrub/tree is common in evergreen forest and in secondary forests that have evergreen patches. [1] It grows from 10 to 200m altitude.
The tree is endemic to southern/peninsular Thailand. [4] [1]
Kha khao and khan laen are names used for this species in Surat Thani Province, Thailand. [1]

It is a small to medium-sized deciduous tree growing to 20 m tall, with a spreading crown. The bark is smooth and thin, and bleeds latex if cut.
