Coccoloba Gigantifolia
''Coccoloba gigantifolia'' is a species of flowering plant in the knotweed family Polygonaceae. It is endemic to the Madeira River Basin in the states of Amazonas and Rondonia in the central and southwestern Brazilian Amazon. This species resembles that of ''Coccoloba mollis'' but differs in that it has much larger leaves in its fertile branches. Description ''Coccoloba gigantifolia'' is a tree which grows to about in height and has leaves that can reach in length, and in width, the third largest known leaf among dicotyledonous plants after Gunnera manicata and Victoria boliviana. The petiole is only about in length and thick. In addition to the large leaves, it can be distinguished from its congeners by the species' straight trunk, rarely over thick, with transverse rings, articulated petiole inserted in the ochrea An ochrea (Latin ''ocrea'', greave or protective legging), also spelled ocrea, is a plant structure formed of stipules fused into a sheath surrounding the ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ...
