Botanical Identification

Ecology

The ecology of Crotalaria agatiflora is characterized by its presence in lowland habitats, where it occupies a specific altitudinal niche. This species thrives within an elevational range that extends from a minimum of 2600 m AMSL to a maximum of 2820 m AMSL. Furthermore, the plant maintains a symbiotic relationship with mycorrhizae, utilizing these fungal associations to support its nutrient uptake and growth within its ecological environment.

Elevational range max:
2820 m AMSL
Elevational range min:
2600 m AMSL
Habitat :
Lowland
Mycorrhiza :
yes

Life history

The life history of Crotalaria agatiflora is characterized by a perennial lifecycle, allowing the plant to persist through multiple growing seasons. Structurally, it is classified as a chamaephyte, a life form where the regenerative buds are located close to the soil surface, typically just above ground level. This species maintains an evergreen deciduousness, retaining its foliage throughout its development rather than shedding it seasonally.

Deciduousness :
evergreen
Life form :
chamaephyte
Lifecycle :
perennial

Morphology

The morphology of Crotalaria agatiflora is characterized by its growth form as a woody shrub, exhibiting a self-supporting structure rather than functioning as a climber or liana. This terrestrial plant maintains an independent existence, as it is neither an epiphyte nor a parasite. In terms of stature, the plant displays significant variability in height, ranging from a minimum of 0.05 m to a maximum of 2 m, with an average plant height of approximately 2.25 m.

Physiology

The physiology of Crotalaria agatiflora is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. The plant's vegetative structure features leaves that exhibit significant morphological variability, with leaf lengths ranging from a minimum of 1 cm to a maximum of 12 cm, and leaf widths spanning from 1 cm to 3.5 cm. Furthermore, the species functions as a nitrogen fixer, utilizing symbiotic relationships to convert atmospheric nitrogen into a usable form, thereby enhancing its nutrient uptake and contributing to soil fertility.

1 cm
Leaf width max:
3.5 cm

Reproduction

The reproduction of Crotalaria agatiflora is characterized by a reliance on sexual processes, as asexual reproduction is absent. The plant utilizes a biotic pollination syndrome, specifically mediated by insects, to facilitate fertilization. Following successful pollination, the plant develops fruits in the form of pods, which reach an average length of 8 cm. These fruits are dehiscent, meaning they split open at maturity to release the seeds. The seeds themselves are remarkably uniform in size, with a consistent mean length of 6 mm (ranging from a minimum to a maximum of 6 mm) and a stable mean mass of 0.02715 g. Regarding the movement of offspring, the species employs an unspecialized dispersal syndrome, lacking highly specific mechanisms for transport.
