Botanical Identification

Ecology

The ecology of Uvaria maccluerei is characterized by a highly specific altitudinal niche, as it is predominantly documented within a narrow elevational range. Based on ecological data, the species maintains a consistent presence at an elevation of 1000 m AMSL, with its minimum, mean, and maximum recorded altitudes all converging at this single point of 1000 m AMSL. This indicates a specialized habitat preference, suggesting that the plant is highly adapted to the specific environmental conditions—such as temperature, atmospheric pressure, and moisture levels—found at this precise mid-to-high altitude tier.

Elevational range max:

1000 m AMSL

Life history

The life history of Uvaria maccluerei is characterized by its status as a perennial species, allowing it to persist in its environment through multiple growing seasons. As a long-lived woody climber, its developmental trajectory involves a sustained period of vegetative growth, during which it develops climbing structures to navigate its habitat. This perennial nature ensures that the plant can undergo repeated cycles of flowering and fruiting, contributing to its long-term reproductive success and ability to maintain a presence within its ecological niche.

perennial

Morphology

The morphology of Uvaria maccluerei is characterized by its growth form as a woody shrub that exhibits a self-supporting climbing habit. As a woody plant, it possesses a sturdy structural framework, though it functions as a self-supporting climber within its natural habitat.

Physiology

The physiological structure of the foliage in Uvaria macclurei is characterized by a distinct range of dimensions that reflect its vegetative growth patterns. The leaves exhibit significant variability in size, with a mean leaf length of 15 cm, though they can reach a maximum length of 18 cm and maintain a minimum length of 12 cm. Complementing this longitudinal variation is a specific width profile, where the leaf width typically averages 7 cm, fluctuating between a minimum of 6 cm and a maximum of 8 cm. This morphological consistency in leaf surface area suggests an adaptive mechanism for optimizing light interception and photosynthetic efficiency within its natural habitat.

Leaf length min:

12 cm

Leaf width max:

8 cm

Leaf width mean:

7 cm

Leaf width min:

6 cm

Reproduction

The reproduction of Uvaria maccluerei culminates in the development of distinct fruit structures that exhibit highly consistent morphological dimensions. The fruit is characterized by a uniform size profile, where the fruit length remains constant at a mean, minimum, and maximum value of 5.5 cm. Similarly, the fruit width shows no variance, maintaining a consistent measurement across its minimum, mean, and maximum values at 3.5 cm. This lack of deviation in fruit dimensions suggests a highly stabilized reproductive output regarding the physical scale of the fruit during its maturation process.

Fruit length max:

5.5 cm

Fruit width max:

3.5 cm
