Botanical Identification

Ecology

The ecology of Baccharis macraei is characterized by its adaptation to a broad altitudinal gradient, allowing it to occupy diverse topographical positions within its habitat. This species thrives across an elevational range that begins at sea level (0 m AMSL) and extends up to a maximum altitude of 500 m AMSL. This vertical distribution suggests a capacity to tolerate varying atmospheric pressures and temperature fluctuations associated with low-lying coastal or lowland regions and slightly more elevated terrains. Its ability to inhabit these varying elevations facilitates its presence in a range of environmental niches, where it must contend with the specific soil compositions and moisture availability characteristic of both lowland plains and mid-elevation slopes.

Elevational range max:

500 m AMSL

Elevational range min:

0 m AMSL

Life history

The life history of Baccharis macraei is characterized by its status as a perennial species, allowing it to persist in its environment through multiple growing seasons. In terms of its structural growth habit and architectural strategy, the plant exhibits a dual classification of life forms, functioning as both a phanerophyte and a nanophanerophyte. As a phanerophyte, it possesses buds located well above the ground level, contributing to its structural presence, while its nanophanerophyte characteristics indicate a tendency toward more compact, low-growing woody growth forms.

Morphology

The morphology of Baccharis macraei is characterized by a woody growth form, specifically classified as a shrub. As a self-supporting plant, it does not exhibit climbing behavior such as a liana or vine, nor does it function as an obligatory or facultative climber. It is an independent organism, lacking any parasitic tendencies, and maintains a terrestrial habit rather than being aquatic, semiaquatic, or epiphytic. Whether considered in terms of its epiphytic status or its general ecological niche, the plant is strictly terrestrial, ensuring a stable, non-epiphytic existence.

Reproduction

Reproduction in Baccharis macraei is characterized by the production of specialized seeds that exhibit a highly consistent physical profile. Based on available morphological data, the seeds are extremely minute, maintaining a uniform weight across all sampled specimens. The seed mass is characterized by a mean value of 0.00019 g, a figure that is mirrored exactly by both the maximum and minimum recorded values of 0.00019 g. This lack of variance in seed mass suggests a highly standardized reproductive output, where each individual seed possesses a strictly defined mass of 0.00019 g, facilitating a uniform dispersal and germination strategy for the species.
