Definition: Open shrubland and savanna in the north of Brazil and in Colombia and Venezuela, with low, sparse vegetation growing on sandy soils mostly within terra firme land in the Amazon. It can be of the ‘forested’ type, similar to a gallery forest, ‘wooded’ where the trees are shorter, and finally ‘grassy-woody’, where it occurs in wet plains near rivers and lakes. Amongst the more frequent plant families are the Arecaceae, Bromeliaceae, Clusiaceae, Humiriaceae, Marantaceae, Meliaceae and Rapateaceae.
Definition: A grassland biome is a terrestrial biome which includes, across its entire spatial extent, an unbroken layer of grasses (Gramineae), sedges (Cyperaceae) or rushes (Juncaceae).
Definition: Forest associated to intermittent water courses, which can be wide (riverine) or narrower and with the canopy meeting over the river (gallery)
Definition: a plant that produces wood as its structural tissue. Wood is a structural cellular adaptation that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Wood is usually primarily composed of xylem cells with cell walls made of cellulose and lignin
Definition: a small cluster of elongated flexible outgrowths attached or close together at the base and free at the opposite ends especially; a growing bunch of grasses or close-set plants"
Definition: In the haploid (gametophyte) lifestage of a moss or fern, the antheridia (male) and archegonia (female) reproductive organs occur on different individual plants
