Botanical Identification

Ecology

The ecology of Tabernaemontana sananho is characterized by its presence in diverse forest environments, specifically thriving within riparian forests (Floresta Ciliar ou Galeria), terra firme forests (Floresta de Terra Firme), and floodplain forests (Floresta de Várzea). This species occupies a specific altitudinal niche, ranging from an elevation of 100 m AMSL up to a maximum of 1500 m AMSL.

Elevational range max:

1500 m AMSL

Elevational range min:

100 m AMSL

Habitat :

Floresta Ciliar ou Galeria, Floresta de Terra Firme, Floresta de Várzea

Life history

The life history of Tabernaemontana sananaho is characterized by a long-term survival strategy, as it functions as a perennial species. In terms of its structural growth and ecological positioning, the plant exhibits a life form classified as a phanerophyte, indicating that its perennially renewing buds are located on branches well above the ground. Additionally, it can be described through the lens of nanophanerophyte traits, reflecting its specific growth habit and stature within its natural habitat.

Life form :

nanophanerophyte

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Tabernaemontana sananaho is characterized by its growth form as a woody tree, which typically reaches an average height of 3.25 m, though it can grow up to a maximum height of 6 m. As a self-supporting plant, it does not exhibit climbing habits such as being a liana or vine, nor does it function as a parasite, maintaining an independent lifestyle. The species is strictly terrestrial in its ecological habit, meaning it is neither an epiphyte nor an aquatic or semiaquatic plant.

Physiology

The physiology of Tabernaemontana sanahni is characterized by a standard C3 photosynthetic pathway, which involves the direct fixation of atmospheric carbon dioxide through the Calvin cycle within the mesophyll cells. As a non-nitrogen-fixing species, the plant does not possess specialized symbiotic relationships with nitrogen-fixing bacteria to convert atmospheric nitrogen into ammonia; instead, it relies entirely on the uptake of dissolved nitrates and ammonium ions from the soil through its root system to meet its metabolic nitrogen requirements.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Tabernaemontana sananaho is characterized by specific morphological and ecological traits involving its fruit and seed dispersal mechanisms. The plant produces dry fruits, which facilitate the release of its seeds. These seeds exhibit a highly consistent physical profile, with a recorded seed volume of exactly 99 mm³ (representing both the minimum, maximum, and mean values) and a uniform seed mass of 0.093 g (also representing the minimum, maximum, and mean values). Regarding its dispersal strategy, the species primarily utilizes a zoochorous syndrome, meaning seeds are dispersed by animals, although the reproductive potential of the species can also be associated with anemochorous, autochorous, hydrochorous, or unspecialized dispersal methods.

Dispersal syndrome :
