Distribution

This plant exhibits a broad distribution across several distinct regions in East Asia. Within China, its presence is noted in the northern territories of Inner Mongolia and Manchuria. It also extends into the central and eastern parts of the country, specifically through China North-Central and China Southeast. Beyond the Chinese borders, the species is also found throughout Mongolia. Collectively, these locations highlight a widespread range across much of the northern and eastern continental landscape.

Botanical Identification

Ecology

The ecology of Cynanchum bungei is characterized by a highly specific altitudinal distribution, as evidenced by its documented elevational range. This species is strictly associated with an elevation of 1500 m AMSL, a value that represents its minimum, mean, and maximum recorded altitude. This precise vertical positioning suggests a specialized niche within its habitat, where the environmental variables associated with this specific height above mean sea level—such as temperature gradients, atmospheric pressure, and moisture availability—play a critical role in its survival and distribution.

Elevational range max:

1500 m AMSL

Morphology

The morphology of Cynanchum bungei is characterized by its growth form as a herb, exhibiting a non-woody structure throughout its vegetative body. As a plant that relies on external support to ascend, it functions as an obligatory climber, utilizing its slender stems to navigate through surrounding vegetation.

Physiology

The physiology of Cynanchum bungei is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation processes and metabolic efficiency. Its vegetative morphology reflects significant variability in leaf dimensions, which play a crucial role in gas exchange and transpiration regulation. The leaves typically exhibit a mean length of 5.5 cm, with individual dimensions ranging from a minimum of 3 cm to a maximum of 8 cm. Concurrently, the leaf width shows a substantial range, maintaining a minimum width of 1 cm and a maximum width of 5 cm, with an average width recorded at 3 cm. This morphological plasticity in leaf surface area likely assists the plant in managing its physiological responses to varying environmental conditions.

Reproduction

The reproduction of Cynanchum bungei is characterized by the development of specific fruit structures that follow a consistent morphological pattern. The fruits produced by this species exhibit a highly uniform size distribution, with a mean length of 9 cm and a mean width of 1 cm. This consistency is further evidenced by the fact that the minimum, mean, and maximum recorded values for fruit length are all 9 cm, while the minimum, mean, and maximum recorded values for fruit width are all 1 cm. Consequently, the fruit morphology remains stable throughout its development, maintaining a standardized dimension of 9 cm in length and 1 cm in width.

Fruit length max:

9 cm

Fruit width max:

1 cm
