Botanical Identification

Ecology

The ecology of Crataegus maximowiczii is characterized by its preference for diverse topographical environments, ranging from lush forest interiors and forest edges to open meadows and mountainous terrain. This species occupies a specific altitudinal niche, typically found at elevations starting from a minimum of 200 m AMSL, reaching a mean elevation of approximately 600 m AMSL, and extending up to a maximum limit of 1000 m AMSL. Its ability to thrive in both sheltered woodland settings and more exposed montane landscapes suggests an adaptability to varying levels of light availability and moisture levels found within these distinct habitats.

Elevational range max:

1000 m AMSL

Elevational range mean:

600 m AMSL

Elevational range min:

200 m AMSL

Habitat :

forest, forest edges, meadows, mountains

Life history

The life history of Crataegus maximowiczii is characterized by its status as a perennial species, meaning it maintains its vegetative structures and lives for many years beyond its initial growth phases. Throughout its multi-year existence, the plant undergoes seasonal cycles of dormancy and active growth, establishing a robust woody framework that allows it to persist in its natural habitat. As a long-lived woody perennial, it does not follow the rapid life cycles of annuals or biennials; instead, it invests energy into perennial survival, structural development, and repeated reproductive cycles over successive growing seasons.

Lifecycle :

perennial

Morphology

The morphology of Crataegus maximowiczii is characterized by a woody growth form that typically manifests as a tree or a shrub. This species is a self-supporting, terrestrial plant that functions as an independent organism, showing no parasitic tendencies. In terms of stature, it reaches a maximum plant height of approximately 7 m, with a mean height also centered around 7 m. Its structural development is defined by its woody nature, providing the necessary stability for its upright, self-supporting habit.

Physiology

The physiology of Crataegus maximowiczii is characterized by a C3 photosynthetic pathway, which governs its carbon fixation processes and metabolic efficiency within its natural environment. The vegetative morphology, particularly regarding its foliage, shows specific dimensional parameters that reflect its physiological structure. The leaves exhibit a varied size distribution, with a minimum leaf length of 4 cm and a mean leaf length of 5 cm, reaching a maximum length of 6 cm. Complementing these longitudinal dimensions, the leaf width ranges from a minimum of 3 cm to a maximum of 5 cm, defining the overall surface area available for light interception and gas exchange.

Reproduction

The reproduction of Crataegus maximowiczii is characterized by its bisexual sexual reproduction system, ensuring that individual flowers possess both male and female reproductive organs. The flowering period typically commences in May and concludes in June, featuring inflorescences that are relatively compact, with lengths ranging from a minimum of 0.04 m to a maximum of 0.05 m. Following successful pollination, the plant produces small fruits that exhibit highly consistent dimensions; both the length and width of the fruit are measured at a uniform 0.8 cm, with the minimum, mean, and maximum values all coinciding at this measurement. The dispersal of these fruits follows a zoochorous syndrome, specifically through endozoochory, where seeds are dispersed after being ingested by animals.
