Botanical Identification

Ecology

The ecology of Smilax bracteata is characterized by its highly specific altitudinal distribution within its native habitat. This species is found within a very narrow ecological niche, occurring exclusively at a consistent elevation. Data regarding its vertical range indicates a singular presence at an elevation of 1750 m AMSL, as both its minimum, mean, and maximum elevation values are recorded at this exact altitude. This lack of altitudinal variance suggests that the plant is strictly adapted to the specific climatic, thermal, and atmospheric conditions found at this precise level above mean sea level.

Elevational range max:

1750 m AMSL

Life history

The life history of Smilax bracteata is characterized by its status as a perennial plant, allowing it to persist in its environment through multiple growing seasons. As a long-lived species, it establishes a robust presence within its habitat, utilizing its perennial nature to navigate seasonal fluctuations and ensure long-term survival. This lifecycle enables the plant to invest in extensive rhizomatous structures, which facilitate vegetative spreading and provide the energy reserves necessary to endure periods of dormancy before emerging again in subsequent years.

Lifecycle :

perennial

Morphology

The morphology of Smilax bracteata is characterized by its growth form as a woody shrub that functions as a self-supporting climber. As an independent organism, it does not rely on a host for nutrients, maintaining a terrestrial lifestyle rather than growing as an epiphyte. The plant exhibits a robust, woody structure that allows it to navigate its environment while remaining structurally stable.

Physiology

The physiology of Smilax bracteata is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency within its ecological niche. The morphological aspects of its foliage play a critical role in its light interception and gas exchange capabilities, exhibiting significant variability in leaf dimensions. The leaves typically maintain a mean length of 11 cm, though they can range from a minimum of 5 cm to a maximum of 17 cm in length. Complementing this longitudinal variation, the leaf width fluctuates between a minimum of 3 cm and a maximum of 11 cm, providing a dynamic surface area that supports its physiological requirements for photosynthesis and transpiration.

Reproduction

The reproduction of Smilax bracteata is characterized by specific morphological dimensions of its flowering and fruiting structures. The plant produces inflorescences that vary in size, with a minimum length of 0.03 m and a maximum length reaching up to 0.07 m. Following the flowering stage, the development of the fruit is highly uniform in its dimensions; the fruit maintains a consistent length and width, with both the minimum, mean, and maximum values recorded at 0.5 cm. Consequently, the fruit presents a symmetrical profile, measuring 0.5 cm in both length and width across its entire developmental range.

Fruit length max:

0.5 cm

Fruit width max:

0.5 cm

Inflorescence length max:

0.07 m

Inflorescence length min:

0.03 m
