Botanical Identification

Ecology

The ecology of Dipsacus asper is characterized by its adaptation to specific altitudinal gradients within its natural habitat. This species thrives within a defined elevational range, typically occupying montane or sub-alpine zones. Specifically, its distribution is bounded by a minimum elevation of 1320 m AMSL and reaches its upper limit at a maximum elevation of 2200 m AMSL. Within this vertical niche, the plant's survival and reproductive success are closely tied to the environmental conditions prevalent at these specific altitudes, which dictate the temperature, moisture availability, and atmospheric pressure it encounters.

Elevational range max:

2200 m AMSL

Elevational range min:

1320 m AMSL

Morphology

The morphology of Dipsacus asper is characterized by its growth form as a non-woody herb. As a herbaceous species, it lacks permanent woody tissue, instead developing soft, green stems that support its upright structure throughout the growing season.

Growth form :

herb

Woodiness :

non-woody

Reproduction

Reproduction in Dipsacus asper is primarily driven by the production of seeds contained within its distinctive, prickly flower heads. The reproductive efficiency of this species is characterized by highly uniform seed metrics, indicating a consistent investment in progeny size. Specifically, the seed mass remains constant across observed samples, with a recorded mean, maximum, and minimum value of 0.00389 g. This precise seed mass of 0.00389 g suggests a standardized developmental process during the maturation of the achenes, ensuring that each seed carries a consistent amount of nutrient reserves to support initial germination and seedling establishment.

Seed mass mean:

0.00389 g
