Botanical Identification

Ecology

The ecology of Myrcia tricona is characterized by its presence within the Floresta Ombrófila (also known as Floresta Pluvial), a high-moisture rainforest environment. This species thrives across a specific altitudinal gradient, occupying lowland areas and extending up to a maximum elevation of 500 m AMSL. Its distribution begins at sea level (0 m AMSL), indicating a preference for the humid, tropical conditions typical of low-to-mid elevation rainforest ecosystems.

Elevational range max:

500 m AMSL

Elevational range min:

0 m AMSL

Habitat :

Floresta Ombrófila (= Floresta Pluvial)

Life history

The life history of Myrcia tricona is characterized by a perennial lifecycle, allowing the plant to persist through multiple growing seasons and establish long-term presence within its ecological niche. As a phanerophyte, its regenerative buds are located high above the ground on woody stems, a structural adaptation that defines its life form. This phanerophyte classification is consistent across its developmental stages, ensuring that the plant maintains a robust, elevated stature throughout its extended lifespan.

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Myrcia tricona is characterized by a woody growth form, specifically manifesting as a self-supporting tree. This plant is primarily terrestrial in its ecological habit, neither functioning as an aquatic, semiaquatic, nor epiphytic organism. It is an independent species that does not exhibit parasitic behavior. Reaching a maximum plant height of approximately 15 meters, the structure is defined by its sturdy, woody development, allowing it to maintain its upright, tree-like stature within its natural habitat.
