Botanical Identification

Ecology

The ecology of Coreopsis lanceolata is characterized by its ability to thrive in anthropized areas (Área Antrópica), indicating a high tolerance for human-disturbed environments. This species occupies a specific altitudinal gradient, ranging from sea level (0 m AMSL) up to a maximum elevation of 500 m AMSL. Regarding its symbiotic relationships within the soil ecosystem, this plant does not form mycorrhizal associations (mycorrhiza: no), suggesting it relies on different nutrient acquisition strategies compared to mycorrhizal-dependent species.

Elevational range max:

500 m AMSL

Elevational range min:

0 m AMSL

Habitat :

Área Antrópica

Mycorrhiza :

no

Genetics

The genetics of Coreopsis lanceolata are characterized by a notable degree of chromosomal variation and polyploidy within the species. Cytogenetic analyses have identified a range of chromosome numbers, specifically recording values of 18, 24, 26, and 48. This variation suggests complex evolutionary processes, likely involving both hybridization and genome doubling events that contribute to the plant's genetic diversity. The presence of higher chromosome numbers, such as 48, indicates the occurrence of polyploid lineages, which can influence the plant's phenotypic plasticity and its ability to adapt to diverse environmental conditions.

Chromosome number :

18, 24, 26, 48

Life history

The life history of Coreopsis lanceolata is characterized by a perennial lifecycle, allowing the plant to persist through multiple growing seasons. As a chamaephyte, its growth form is defined by buds located close to the soil surface, which helps it navigate various environmental conditions. The plant exhibits variable deciduousness, meaning its foliage may shed or remain depending on seasonal shifts and local climatic influences.

Deciduousness :

variable

Life form :

chamaephyte

Lifecycle :

perennial

Morphology

The morphology of Coreopsis lanceolata is characterized by its growth form as a non-woody herb and forb. This self-supporting plant typically grows in a terrestrial habitat, functioning as an independent organism without parasitic or epiphytic tendencies. In terms of stature, it is a relatively low-growing species with a plant height that ranges from a minimum of 0.2 m to a maximum of 1 m, maintaining a mean height of approximately 0.555 m.

Physiology

The physiology of Coreopsis lanceolata is characterized by a C3 photosynthetic pathway, which governs its carbon fixation processes and energy production. The plant's vegetative structure is defined by its foliage, where leaf dimensions exhibit significant variability; the leaves typically maintain a mean length of 5.25 cm, ranging from a minimum of 3.5 cm to a maximum of 30 cm, while the width varies from a minimum of 0.5 cm to a mean and maximum of 2 cm. Furthermore, the species does not function as a nitrogen fixer, relying instead on the availability of nitrogen within the soil substrate to support its metabolic requirements and growth.

Reproduction

The reproduction of Coreopsis lanceolata is characterized by a sexual process involving bisexual flowers, with asexual reproduction being notably absent. The flowering period typically begins in June and concludes in August. The plant relies on a biotic pollination syndrome, specifically utilizing insects for pollination, and self-fertilization is absent, which promotes genetic diversity through cross-pollination. Following successful fertilization, the plant produces fruits classified as achenes. These fruits are indehiscent and vary in length, with a minimum of 0.2 cm, a mean of 0.2875 cm, and a maximum of 0.3 cm. Each fruit is highly prolific, containing more than 1,000 seeds. The seeds themselves are uniform in size, maintaining a consistent length of 3 mm. In terms of mass, the seeds range from a minimum of 0.0006 g to a maximum of 0.0021 g, with a mean seed mass of approximately 0.001555 g. Finally, the dispersal syndrome is anemochorous, meaning the seeds are dispersed by the wind.
