Botanical Identification

Ecology

The ecology of Teucrium cubense is characterized by a broad altitudinal distribution, allowing it to inhabit diverse topographical zones. It is found across a significant vertical gradient, ranging from sea level up to a maximum elevation of 1700 m AMSL. This wide elevational range suggests that the species possesses a high degree of ecological plasticity, enabling it to adapt to the varying climatic conditions, temperature fluctuations, and moisture levels found between coastal lowlands and higher montane environments.

Elevational range max:

1700 m AMSL

Elevational range min:

0 m AMSL

Life history

The life history of Teucrium cubense is characterized by its status as a perennial plant, ensuring its presence in its ecological niche over multiple growing seasons. In terms of its structural growth habit and survival strategy, it is classified as a chamaephyte, a life form where the perennating buds are located close to the soil surface, typically just above the ground level. This chamaephyte classification, consistent across both its primary and secondary life form descriptors, allows the plant to withstand various environmental pressures by maintaining its regenerative capacity near the substrate.

Life form :

chamaephyte

Lifecycle :

perennial

Morphology

The morphology of Teucrium cubense is characterized by its growth form as a herb, specifically categorized as a non-woody herb or forb. It functions as an independent organism, exhibiting no parasitic behavior, and is primarily a terrestrial plant rather than an epiphyte. In terms of its physical habit, it is a self-supporting plant that does not act as a climber, liana, or vine, maintaining a stable structure without the need for external support. While its habitat can range across aquatic, semiaquatic, and terrestrial environments, its fundamental structural classification remains that of a non-woody, self-supporting terrestrial herb.

Reproduction

The reproduction of Teucrium cubense is characterized by the production of small seeds that exhibit specific mass variations within the species. Quantitative analysis of these seeds reveals a mean seed mass of 0.002095 g, indicating a highly consistent size profile during the reproductive phase. The individual seed weights show a narrow range of fluctuation, with the minimum observed seed mass recorded at 0.00149 g and the maximum seed mass reaching up to 0.0027 g. This data suggests a controlled dispersal mechanism involving lightweight propagules that fall within a tight weight distribution.
