Botanical Identification

Ecology

The ecology of Tanacetum pulchrum is defined by its specialization in high-altitude environments, specifically occupying a precise elevational range centered at 2600 m AMSL. This species thrives in rugged and open landscapes, demonstrating a strong preference for habitats such as meadows, mountains, and stony places. Its ability to colonize these demanding, rocky terrains suggests an adaptation to well-drained soils and the intense environmental conditions typical of montane ecosystems at its specific altitudinal threshold of 2600 m AMSL.

Elevational range max:

2600 m AMSL

Habitat :

meadows, mountains, stony places

Life history

The life history of Tanacetum pulchrum is characterized by its nature as a perennial plant, allowing it to persist through multiple growing seasons. As a perennial species, it establishes a robust root system that enables the plant to survive periods of dormancy and regrow annually, distinguishing it from annual or biennial life cycles. This enduring lifecycle supports its ability to develop dense foliage and produce its distinctive flowering structures year after year, contributing to its long-term presence within its natural habitat.

Lifecycle :

perennial

Morphology

The morphology of Tanacetum pulchrum is characterized by its growth form as a non-woody herb, specifically classified as a forb. This plant is a self-supporting, terrestrial species that grows independently without parasitic behavior. In terms of stature, it is a relatively low-growing specimen with a plant height that typically ranges from a minimum of 0.1 m to a maximum of 0.35 m, maintaining an average height of approximately 0.25 m.

Physiology

The physiological structure of the foliage in Tanacetum pulchrum is characterized by significant morphological variation in leaf dimensions, which plays a critical role in its photosynthetic capacity and transpiration regulation. The leaves exhibit a diverse size range, with individual leaf lengths spanning from a minimum of 2 cm to a maximum of 10 cm, maintaining a mean length of approximately 6 cm. Complementing this longitudinal variation is a specific width profile, where the leaves maintain a narrow morphology, measuring as little as 1 cm at their minimum width and reaching a maximum width of 2 cm. This specific ratio of length to width suggests a physiological adaptation to optimize light interception while managing moisture loss through the leaf surface.

Reproduction

The reproduction of Tanacetum pulchrum is characterized by its bisexual flowers, which facilitate sexual reproduction through a single reproductive structure. The flowering period for this species typically commences in July and concludes in August. Following successful pollination, the plant produces small fruits with a mean length of 0.275 cm, ranging from a minimum of 0.25 cm to a maximum of 0.3 cm. The dispersal of these fruits follows an anemochorous syndrome, meaning they are primarily dispersed by the wind.
