Botanical Identification

Life history

The life history of Achillea collina is characterized by its existence as a perennial species, allowing it to persist through multiple growing seasons. Structurally, the plant functions as a hemicryptophyte, meaning its perennable buds are located at or just below the soil surface, protected by leaf litter or soil during unfavorable conditions. This life form facilitates its resilience in its natural habitat. Furthermore, the plant exhibits a deciduous nature, shedding its foliage during dormant periods to conserve energy and resources.

Deciduousness :

deciduous

Life form :

hemicryptophyte

Lifecycle :

perennial

Morphology

The morphology of Achillea collina is characterized by its growth form as a non-woody herb. This species is a self-supporting, terrestrial plant that functions independently, lacking any parasitic or epiphytic behavior. In terms of stature, it exhibits a relatively low growth habit with a plant height that varies between a minimum of 0.25 m and a maximum of 0.6 m, maintaining an average height of approximately 0.55 m.

Physiology

The physiology of Achillea collina is characterized by a C3 photosynthetic pathway, a common metabolic strategy for plants in this genus that optimizes carbon fixation under moderate environmental conditions. Morphologically, the plant exhibits a mean leaf size of approximately 10.3749 cm², reflecting its structural adaptation to light interception and gas exchange. This leaf morphology is further quantified by a mean Specific Leaf Area (SLA) of 174 cm²/g, a value that provides insight into the plant's leaf thickness and resource allocation strategies, balancing the efficiency of light capture with the metabolic costs of leaf tissue maintenance.

Reproduction

The reproduction of Achillea collina is characterized by a specific seasonal flowering period and specialized pollination and dispersal mechanisms. The plant enters its flowering phase in July and continues until November. During this time, it utilizes a biotic pollination syndrome, specifically relying on insects to facilitate the reproductive process; notably, self-fertilization is absent, indicating a reliance on cross-pollination. The resulting seeds are extremely lightweight, with a mean mass of 0.00014325 g, ranging from a minimum of 0.000117 g to a maximum of 0.00016 g. For the spread of its offspring, the species employs an anemochorous dispersal syndrome, meaning the seeds are dispersed by the wind.
