Definition
Knema intermedia is the scientific (binomial) name of a flowering plant species belonging to the family Myristicaceae, the nutmeg family.
Overview
The species is reported from tropical regions of Southeast Asia, with occurrences documented in parts of Malaysia, Indonesia, and possibly Thailand. As a member of Myristicaceae, it is presumed to be an evergreen tree that inhabits lowland and hill forests. The taxonomic authority for the name is often cited as (J.J.Sm.) Warb., indicating that the original description was made by J.J. Smith and later transferred to the genus Knema by Otto Warburg.
Etymology / Origin
- Genus name: Knema is derived from the Greek word “knyma” (κνῡμή), meaning “knot” or “node,” a reference that may pertain to the characteristic stipules or bud structures of the genus.
- Species epithet: intermedia comes from the Latin adjective intermedius, meaning “intermediate” or “in between,” likely reflecting morphological features that were considered intermediate between related Knema species at the time of description.
Characteristics
- Growth form: An evergreen tree, typically reaching heights of 10–20 m, though exact maximum size is not consistently recorded.
- Leaves: Simple, alternate, and elliptic to oblong; leaf blades are generally glossy with a leathery texture. Precise measurements of leaf length and width are not uniformly reported.
- Inflorescence: The species bears axillary or terminal panicles of small, unisexual flowers, a common trait in Myristicaceae. Detailed descriptions of flower morphology (e.g., tepals, stamens) are limited in publicly accessible sources.
- Fruit: Produces a fleshy, indehiscent drupe typical of the family, containing a single seed surrounded by a thick aril. Specific attributes such as fruit size, coloration, and seed morphology are not thoroughly documented.
- Ecology: Like other nutmeg‑family members, K. intermedia is presumed to rely on animal vectors (e.g., birds, mammals) for seed dispersal, but direct studies confirming this are lacking.

Note: While Knema intermedia appears in several taxonomic databases (e.g., Plants of the World Online, Tropicos), detailed botanical literature on the species is sparse. Consequently, some descriptive information above is based on general characteristics of the genus and family, and precise data for K. intermedia are not comprehensively documented. Accurate, species‑specific information is not fully confirmed.
