Botanical Identification

Ecology

The ecology of Coleus henryoides is characterized by its ability to thrive within a diverse altitudinal gradient, reflecting its adaptability to varying environmental conditions. This species is distributed across a significant vertical range, occupying habitats from low-lying areas at an elevation of 305 m AMSL up to much higher montane regions reaching a maximum of 1830 m AMSL. This broad elevational span suggests that the plant can tolerate a wide spectrum of temperature regimes, atmospheric pressures, and moisture availability, allowing it to colonize various ecological niches within its native landscape. Such a wide distribution likely enables the species to persist across different microclimates, from warmer, more humid lowland environments to the cooler, potentially more seasonal conditions found at its upper altitudinal limits.

Elevational range max:

1830 m AMSL

Elevational range min:

305 m AMSL

Life history

The life history of Coleus henryeonsis is characterized by its classification as a perennial plant, allowing it to persist through multiple growing seasons. In terms of its structural growth patterns and survival strategies, the species exhibits a complex life form profile, manifesting as both a phanerophyte and a nanophanerophyte. This dual classification indicates that while it can develop woody or elevated stems to survive different environmental conditions, it also maintains a growth habit where the shoot system is kept relatively close to the ground, ensuring its continued presence within its ecological niche over its multi-year lifespan.

Morphology

The morphology of Coleus henryeonsis is characterized by its growth form as a self-supporting herb, exhibiting a non-climbing habit. It functions as an independent organism, neither acting as a parasite nor as an epiphyte, as it maintains a strictly terrestrial existence. The plant's structure displays a woody nature and can reach a maximum plant height of 1 m. While its habitat can vary across aquatic, semiaquatic, and terrestrial environments, its physical development remains consistent with a herbaceous, self-supporting structure.

Reproduction

Reproduction in Coleus heroeensis occurs through the production of specialized seeds that exhibit specific morphological and weight characteristics essential for its propagation. The seed mass of this species is notably minute, reflecting a strategy often associated with high-volume dispersal. Quantitative analysis of the seed weight reveals a mean seed mass of 0.00029 g, indicating a highly consistent size among the progeny. Within the population, there is a slight degree of variability, with the individual seed masses ranging from a minimum of 0.00023 g to a maximum of 0.00036 g. This precise range of seed mass contributes to the plant's reproductive capacity and its ability to establish itself within its ecological niche.
