Botanical Identification

Ecology

The ecology of Tephrosia semiglabra is defined by its adaptability to diverse montane and sub-montane environments, thriving within a specific altitudinal gradient. This species is primarily distributed across mid-to-high altitude terrains, occupying a vertical niche that extends from a minimum elevation of 793 m AMSL to a maximum elevation of 1891 m AMSL. This broad elevational range suggests that the plant is capable of tolerating varying thermal regimes and atmospheric pressures associated with ascending slopes. Its presence within these specific altitudinal limits indicates a preference for habitats that provide the particular moisture levels and soil compositions found within these subtropical or tropical highland zones, allowing it to persist in ecological niches ranging from lower montane forests to higher, more temperate-leaning scrublands.

1891 m AMSL

Elevational range min:

Life history

The life history of Tephrosia semiglabra is characterized by a perennial lifecycle, allowing the plant to persist in its environment over multiple growing seasons. As a perennial species, it does not complete its biological cycle within a single year but instead maintains its vegetative structure to support repeated reproductive efforts. This longevity enables the plant to establish a stable presence within its ecological niche, potentially through the development of woody bases or persistent root systems that facilitate survival through varying seasonal conditions. This perennial nature distinguishes it from annual or biennial species, providing a consistent biological framework for its continued growth and seasonal flowering cycles.

Morphology

The morphology of Tephrosia semiglabra is characterized by a growth form categorized as a herb, which exhibits a non-woody structure. As a self-supporting plant, it does not function as a climber and maintains an independent existence, lacking any parasitic or epiphytic lifestyle, specifically occupying terrestrial habitats. The plant displays significant variation in stature, with a height ranging from a minimum of 0.1 m to a maximum of 4 m.
