Botanical Identification

Ecology

The ecology of Coreopsis tinctoria is characterized by its preference for lowland habitats, where it thrives within a specific altitudinal gradient. This species is typically found at elevations ranging from a minimum of 200 m AMSL to a maximum of 500 m AMSL. These environmental parameters suggest that the plant is adapted to lower-lying terrains, occupying ecological niches that are defined by these specific elevational constraints.

Elevational range max:

500 m AMSL

Elevational range min:

200 m AMSL

Habitat :

Lowland

Life history

The life history of Coreopsis tinctoria is characterized by its classification as an annual plant, meaning it completes its entire biological cycle—from germination and vegetative growth to flowering and seed production—within a single growing season. As an annual species, it relies on the rapid production of a high volume of seeds to ensure the survival of the next generation, as the parent plant typically dies off after the reproductive phase is complete. The cycle begins with seed germination in favorable soil conditions, followed by a period of rapid development where the plant establishes its foliage and structural framework. Once mature, it transitions into a prolific flowering stage, attracting pollinators to facilitate fertilization. Following successful pollination, the plant directs its energy into developing seed heads, eventually dispersing its seeds to await the next seasonal cycle, effectively resetting the life history process for the subsequent population.

annual

Morphology

The morphology of Coreopsis tinctoria is characterized by its growth form as a non-woody herb and specifically a forb. This plant is a self-supporting species, meaning it does not function as a climber, liana, or vine, and it grows as an independent organism rather than a parasite. It is strictly a terrestrial plant, lacking any aquatic, semiaquatic, or epiphytic characteristics. In terms of stature, the plant typically reaches a minimum height of 0.3 m, with a mean height of approximately 0.74 m, and can attain a maximum height of up to 1.2 m.

Physiology

The physiology of Coreopsis tinctoria is characterized by a C3 photosynthetic pathway, a metabolic strategy common to most dicotyledonous plants where carbon fixation occurs primarily through the Calvin cycle during the light-independent reactions. This pathway involves the initial fixation of atmospheric CO2 by the enzyme RuBisCO to form a three-carbon compound, which is efficient under temperate environmental conditions. Furthermore, regarding its nutrient acquisition strategies, Coreopsis tinctoria is not a nitrogen fixer; it lacks the symbiotic relationship with diazotrophic bacteria, such as Rhizobium, necessary to convert atmospheric nitrogen into bioavailable forms, and therefore relies on the uptake of nitrates and ammonium from the soil to meet its metabolic nitrogen requirements.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Coreopsis tinctoria is driven by a biotic pollination syndrome, primarily facilitated by insects, with bees playing a specific and significant role in the process. The flowering period is extensive, typically beginning in June and continuing through October. Following successful pollination, the plant develops small fruits, which exhibit a mean length of 0.275 cm, ranging from a minimum of 0.25 cm to a maximum of 0.3 cm. The resulting seeds are characterized by a very low mass, with an average weight of approximately 0.0002170665 g; these individual seeds vary in size from a minimum of 0.0002 g to a maximum of 0.00036 g.
