Botanical Identification

Ecology

The ecology of Psellophus sibiricus is characterized by its adaptation to specific high-altitude terrain, primarily thriving within mountainous regions, steppe environments, and stony places. This species maintains a highly specialized distribution pattern, occupying a consistent elevational range that centers at a mean of 1200 m AMSL. This narrow ecological niche is defined by a stable altitudinal band, with both its minimum and maximum recorded elevation reaching 1200 m AMSL, indicating a precise environmental requirement for its survival within these rugged, rocky, and open landscapes.

Elevational range max:

1200 m AMSL

Habitat :

mountains, steppe, stony places

Life history

The life history of Psiphalus sibiricus is characterized by its status as a perennial species, allowing it to persist through multiple growing seasons. As a perennial plant, it maintains a continuous presence in its habitat, often developing robust root systems or rhizomes that facilitate regrowth after periods of dormancy. This lifecycle enables the plant to establish itself firmly within its ecological niche, contributing to its long-term survival and ability to reproduce across several years. Unlike annuals that complete their cycle in a single season or biennials that require two years to flower, the perennial nature of Psiphalus sibiricus provides it with the biological stability to withstand seasonal environmental fluctuations.

Lifecycle :

perennial

Morphology

The morphology of Pssephellus sibiricus is characterized by its herbaceous growth form, presenting as a non-woody herb. This plant exhibits a relatively low stature, with a plant height ranging from a minimum of 0.07 m to a maximum of 0.54 m. In terms of its structural habit, it is classified as a self-supporting herb, maintaining its posture without the need for external climbing structures.

Physiology

The physiology of Psephellus sibiricus is characterized by distinct morphological parameters of its foliage that reflect its vegetative development. The leaves exhibit a controlled growth pattern with a mean leaf length of 5 cm, providing the necessary surface area for photosynthetic activity. In terms of lateral expansion, the leaf width demonstrates significant variability, ranging from a minimum of 2 cm to a maximum of 3 cm, resulting in an average leaf width of 2.5 cm. This structural dimensioning of the leaf blades is essential for the plant's metabolic efficiency and its ability to regulate gas exchange and transpiration within its specific environmental niche.

Leaf length mean:

5 cm

Leaf width max:

3 cm

Leaf width mean:

2.5 cm

Leaf width min:

2 cm

Reproduction

The reproduction of Psellophus sibiricus is characterized by a specific flowering window and the production of small, uniform fruit. The flowering period typically commences in June and concludes in July, though the timing can be variable. Following pollination, the plant develops fruit that exhibit highly consistent dimensions; the fruit length remains constant at a mean, minimum, and maximum of 0.65 cm. Similarly, the fruit width is uniform throughout its development, maintaining a consistent measurement of 0.18 cm for its minimum, mean, and maximum values.
