Combretum rotundifolium
Combretum rotundifolium, the monkey brush or monkey brush vine, is a plant species in the genus Combretum found in South America. Combretum rotundifolium contains acidic dammarane arabinofuranosides. The bright yellow/red flowers are the decoration of the interior where the color green is in abundance. When in blossom the flower buds will slowly burst open giving this exotic vine its 'monkey brush' appearance. References
