(One minor problem seems to be that the Osteichthyes article is quite difficult to find when just browsing via links - maybe including the Osteichthyes as a super-class in the taxobox would help - currently the next highest order shown in the Actinopterygii taxobox is Chordata - which misses the subdivision of that phylum.)
The upper branches of the tree tend to droop. [6] The tree's pinnately compound leaves measure 8–25 cm long × 4–9 cm wide and are made up of 19–41 alternate leaflets. [6] [10] Male and female flowers occur on separate plants . [6] Flowers are small, white and borne profusely in panicles at the ends of the drooping branches. [10]
Madeira vine can climb 40 m into the tree canopy, smothering and collapsing mature trees. [8] The vine grows prolifically; in plentiful sunlight, it can grow up to one metre in a week. [ 8 ] It is also capable of surviving in low light conditions, including under an intact canopy, as a small plant, awaiting its opportunity to grow long stems ...
