Botanical Identification

Ecology

The ecology of Barleria prionitis is characterized by a highly specific altitudinal niche, as it is found at a consistent elevation of 600 m AMSL. This uniformity in its elevational range, with a minimum, mean, and maximum value all converging at 600 m AMSL, suggests a specialized adaptation to particular topographical and climatic strata within its habitat. Such a precise elevational preference often indicates that the species thrives within a narrow band of environmental conditions, likely governed by specific temperature gradients, atmospheric pressure, and moisture levels unique to this altitude. This ecological stability at a fixed elevation suggests that the plant's survival and reproductive success are closely tied to the distinct microclimates found at this precise level above sea level.

Elevational range max:

600 m AMSL

Life history

The life history of Barleria prionitis is characterized by its nature as a perennial plant, allowing it to persist through multiple growing seasons. Throughout its developmental stages, the species maintains an evergreen habit, ensuring that its foliage remains functional and present across varying environmental conditions rather than undergoing a seasonal shedding period.

Deciduousness :

evergreen

Lifecycle :

perennial

Morphology

Morphologically, Barleria prionitis is characterized as a woody shrub that exhibits a self-supporting growth habit, meaning it does not function as a climber, vine, or liana. As a terrestrial plant, it is neither aquatic nor an epiphyte, and it maintains an independent life cycle without being a parasite. The plant typically reaches a mean height of approximately 1.45 m, though its stature can vary, with recorded maximum heights reaching around 0.75 m in specific growth conditions.

Physiology

The physiology of Barleria prionitis is characterized by specific morphological and metabolic adaptations suited to its growth environment. In terms of its vegetative structure, the plant exhibits a consistent leaf development pattern with a leaf length mean of 5 cm. Regarding its nutrient acquisition processes, the species does not function as a nitrogen fixer, meaning it relies on soil-available nitrogen rather than symbiotic nitrogen-fixing bacteria to meet its metabolic requirements. These physiological traits contribute to its overall survival and resource management within its natural ecosystem.

Leaf length mean:

5 cm

Nitrogen fixer :

no

Reproduction

The reproduction of Barleria prionitis involves the development of specialized fruit structures that follow consistent morphological patterns. The fruit produced by this plant is highly uniform in its dimensions, exhibiting no significant variation in size. Specifically, the fruit length is characterized by a consistent mean value of 1.8 cm, which also serves as both the minimum and maximum length recorded. Similarly, the fruit width displays a stable profile, maintaining a mean, minimum, and maximum value of 0.25 cm. This lack of dimensional variance indicates a highly standardized reproductive output in terms of the fruit's physical characteristics.

Fruit length max:

1.8 cm

Fruit width max:

0.25 cm
