Botanical Identification

Ecology

The ecology of Calea oliveiri is defined by its preference for specific high-altitude environments, thriving within a narrow elevational range that extends from a minimum of 1900 m AMSL to a maximum of 2100 m AMSL. This plant is primarily found in specialized habitats, specifically within forest and riverine ecosystems, where the presence of moisture and shade likely plays a crucial role in its survival and growth patterns.

Elevational range max:

2100 m AMSL

Elevational range min:

1900 m AMSL

Habitat :

forest, riverine

Morphology

The morphology of Calea oliveri is characterized by its distinct growth habits and structural composition. It is primarily classified as a woody shrub, exhibiting a robust, woody texture rather than being non-woody or variable. As a terrestrial species, it does not inhabit aquatic or semiaquatic environments, nor does it function as an epiphyte; it is strictly terrestrial in its growth pattern. The plant is independent in its nutritional acquisition, showing no parasitic tendencies such as obligatory or facultative parasitism. Furthermore, it does not exhibit climbing behaviors like vines or lianas, as it is a self-supporting structure that maintains its own upright form without the need for external support.

Reproduction

The reproduction of Calea oliveferi is characterized by the production of minute seeds that play a critical role in its dispersal and propagation strategies. These seeds exhibit a highly consistent physical profile, with a recorded mean seed mass of 0.000384 g. The variation within the seed population is minimal, as evidenced by a maximum seed mass of 0.00043 g and a minimum seed mass of 0.000338 g. This small scale of seed mass suggests a reproductive strategy optimized for high-volume seed production, likely facilitating effective distribution within its natural habitat.
