Botanical Identification

Ecology

The ecology of Lysimachia davurica is characterized by its preference for diverse, moisture-rich environments, specifically thriving within wet meadows, mountainous terrains, shrubberies, and swamps. This species exhibits a highly specific altitudinal distribution, with its ecological niche concentrated at a consistent elevation. Based on recorded data, the plant is found at a mean elevation of 2100 m AMSL, a value that simultaneously serves as its minimum and maximum elevational range, indicating a specialized adaptation to these high-altitude, humid habitats.

Elevational range max:

2100 m AMSL

Habitat :

meadows: wet, mountains, shrubberies, swamps

Life history

The life history of Lysimachia davurica is characterized by a perennial lifecycle, allowing the plant to persist through multiple growing seasons. In terms of its structural growth and survival strategies, it is classified as a cryptophyte, ensuring its regenerative organs remain protected below the soil surface during unfavorable conditions. Specifically, its life form is identified as a geophyte, a classification that highlights its reliance on underground storage organs to navigate seasonal changes and maintain long-term viability within its ecosystem.

Morphology

The morphology of Lysimachia davurica is characterized by its growth as a non-woody herb, exhibiting a consistent herb and forb growth form. The plant maintains an erect shoot orientation and functions as an independent organism, neither acting as a parasite nor an epiphyte, as it is strictly terrestrial in its habitat. In terms of stature, the plant typically reaches a mean height of 0.6 m, with individual specimens ranging from a minimum height of 0.4 m to a maximum height of 0.8 m.

Physiology

The physiology of Lysimachia davurica is characterized by distinct morphological dimensions of its foliage, which serve as critical indicators of its vegetative development and photosynthetic capacity. The leaf structure exhibits significant variability in size, with leaf lengths ranging from a minimum of 4 cm to a maximum of 12 cm, maintaining an average length of approximately 8 cm. Correspondingly, the leaf width shows a broad developmental spectrum, fluctuating from a minimum of 0.5 cm to a maximum of 4 cm, with a mean width calculated at 2.25 cm. These dimensional parameters reflect the plant's adaptive growth patterns and its ability to optimize surface area for light interception within its ecological niche.

Reproduction

The reproduction of Lysimachia davurica is characterized by bisexual flowers, which facilitate sexual reproduction through the presence of both male and female reproductive organs within the same flower. The flowering period typically begins in July and continues through August, although the timing can be variable. Following successful pollination, the plant produces small fruits that exhibit specific morphological dimensions: the fruit length varies from a minimum of 0.2 cm to a maximum of 0.4 cm, with an average length of 0.3 cm. Similarly, the fruit width ranges from a minimum of 0.2 cm to a maximum of 0.4 cm, maintaining a mean width of 0.3 cm.
