Botanical Identification

Ecology

The ecology of Corymbia maculata is defined by its adaptation to specific topographical and environmental gradients, thriving within a landscape where it can ascend to significant heights. The species exhibits a broad altitudinal distribution, reaching an elevational range maximum of 1000 m AMSL. Interestingly, the ecological niche of this plant is characterized by an elevational range mean that sits at 1000 m AMSL, suggesting that its optimal growing conditions and population density are concentrated at these higher altitudes. This distribution pattern implies a specialized tolerance for the climatic variations associated with such elevations, influencing its role within the local ecosystem and its interactions with surrounding flora and fauna.

Elevational range max:
1000 m AMSL

Life history

The life history of Corymbia maculata is characterized by a perennial lifecycle, allowing the individual to persist through many growing seasons. As a phanerophyte, its reproductive buds are located high above the ground on woody branches, a structural adaptation that defines its stature as a large tree. This species maintains an evergreen deciduousness, ensuring that its foliage remains functional throughout the year rather than shedding seasonally. This combination of a long-lived perennial habit and a phanerophyte life form enables the plant to establish a dominant presence within its ecological niche.

Morphology

The morphology of Corymbia maculata is characterized by its stature as a large, woody tree that is fundamentally self-supporting rather than acting as a climber or vine. As a terrestrial species, it is neither aquatic nor an epiphyte, maintaining an independent life cycle without parasitic tendencies. The plant exhibits significant vertical growth, reaching a minimum height of 25 m, with a mean height of approximately 30.17 m, and can attain a maximum height of up to 60 m. Its structural integrity is defined by a robust, woody growth form that allows it to thrive as a prominent component of its ecosystem.

Physiology

The physiology of Corymbia maculata is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency within its native environment. The vegetative structure is supported by leaves that exhibit significant morphological variation in size; specifically, leaf length ranges from a minimum of 10 cm to a maximum of 30 cm, with a recorded mean length of 20 cm. Complementing these dimensions, the leaf width fluctuates between a minimum of 1.5 cm and a maximum of 3 cm. Furthermore, this species does not function as a nitrogen fixer, meaning it relies on existing soil nutrient availability rather than symbiotic nitrogen-fixing bacteria to fulfill its nitrogen requirements.

Reproduction

The reproduction of Corymbia maculata is driven by a biotic pollination syndrome, relying heavily on various animal vectors, specifically insects and bees, to facilitate fertilization. The flowering process involves inflorescences that vary in size, typically ranging from a minimum length of 0.03 m to a maximum of 0.05 m. Following successful pollination, the plant develops woody fruits that exhibit consistent dimensions; the fruit width is remarkably stable at approximately 1 cm (ranging from a minimum of 1 cm to a maximum of 1 cm), while the fruit length fluctuates between a minimum of 1.2 cm and a maximum of 1.5 cm, with a mean length of 1.35 cm. The resulting seeds are quite small, characterized by a minimum mass of 0.00353 g and a maximum mass of 0.01641 g, resulting in a mean seed mass of approximately 0.0606108335 g.
