Botanical Identification

Ecology

The ecology of Deloniox regia is characterized by a broad altitudinal distribution, ranging from sea level (0 m AMSL) up to a maximum elevation of 1540 m AMSL, with a mean elevational occurrence of approximately 275 m AMSL. Regarding its preferred environmental settings, the species is frequently documented within "Área Antrópica" (anthropic areas), indicating a high degree of adaptability to landscapes modified by human activity, such as urban environments, gardens, and agricultural zones.

Elevational range max:
1540 m AMSL
Elevational range mean:
275 m AMSL
Elevational range min:

Genetics

The genetics of Delonix regia are characterized by specific cytological profiles that define its reproductive and evolutionary biology. The plant exhibits variation in its chromosome number, with documented counts of 24 and 28 chromosomes. Furthermore, it is classified by a ploidy level of 2, indicating that the species is primarily diploid.

Chromosome number :
24, 28
Ploidy :
2

Life history

The life history of Deloniidx regia is characterized by its status as a perennial plant, allowing it to persist through multiple growing seasons and establish a long-term presence in its ecosystem. As a phanerophyte, its reproductive buds are borne on aerial shoots well above the ground, a structural adaptation that supports its development into a large, canopy-forming tree. In terms of its foliage patterns, the species is categorized as evergreen, maintaining its leaves to sustain metabolic processes and photosynthetic activity throughout its life cycle.

Deciduousness :
evergreen
Life form :
phanerophyte
Lifecycle :
perennial

Morphology

The morphology of Delonix regia is characterized by its robust growth form as a woody tree. It is a self-supporting, independent organism that does not function as a climber, vine, or liana, nor does it exhibit parasitic or epiphytic behavior, remaining strictly terrestrial in its habitat. The plant typically reaches a significant stature, with a height ranging from a minimum of 5 m to a maximum of 15 m, maintaining an average height of approximately 15 m. Its structural integrity is defined by its woody nature, supporting its development as a large, freestanding tree.

Physiology

The physiology of Delonix regia is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. The plant exhibits a non-succulent morphology, lacking specialized water-storage tissues in its foliage. Its foliar dimensions are highly variable, with leaf lengths ranging from a minimum of 0.5 cm to a maximum of 60 cm, while the leaf width fluctuates between 0.2 cm and 0.5 cm. Structurally, the plant possesses a stem with a mean specific density (SSD) of 519 mg/cm³, reflecting its wood density and internal structural integrity. Furthermore, despite belonging to a family often associated with symbiotic relationships, this species is not a nitrogen fixer, relying instead on external soil nutrient availability for its nitrogen requirements.

Reproduction

The reproduction of Delonix regia is driven by a biotic pollination syndrome, primarily utilizing insects, with bees playing a significant role in the process. The plant produces vibrant red flowers to attract these pollinators. Following successful fertilization, the plant develops a characteristic pod-type fruit. These pods vary in size, reaching a minimum length of 20 cm and a maximum length of 70 cm, with a width ranging from 3 cm to 7 cm. The fruits are dehiscent, meaning they split open to release the seeds. Each fruit contains a substantial quantity of seeds, typically ranging from 11 to 100 seeds per pod. The seeds themselves are relatively uniform, with a length between 20 mm and 25 mm and a width between 6 mm and 8 mm. In terms of mass, the individual seeds have a mean weight of approximately 0.4562135 g, with values ranging from a minimum of 0.32595 g to a maximum of 0.48232 g. While the natural dispersal mechanisms vary, the plant is also noted for its anthropochorous dispersal syndrome, where human activity aids in its spread.
