The Euterpeae are a tribe of the palm family (Arecaceae).
features
The representatives of the Euterpeae are slender to robust palms that have no or one upright trunk. The leaves are pinnate, the tips of the leaflets have entire margins. The leaves can also be in two parts. The leaf sheaths usually form a crown shaft. The inflorescences stand between, less often under the leaves. They are simply branched, less often spike-shaped. The flowers are in the lower inflorescence area in triads, higher up are male flowers in pairs or individually. Female flowers have free petals , which overlap like roof tiles in the lower area, and above stand together like a flap. The staminodes are small and not fused into a ring. The stamp is pseudomonomer. The fruit has a smooth exocarp .
distribution
The representatives occur in humid rainforests in Central and South America and the Caribbean. They occur from low to high above sea level.
Systematics
The udder peae as defined by Dransfield et al. (2008) are identified as natural relatives ( Monophylum ) in most studies . They are part of the "core arecoids", but their exact systematic position within the Arecoideae is unclear.
Five genera are counted to the tribe:
