Botanical Identification

Ecology

The ecology of Hydnocarpus kurzii is characterized by a highly specific altitudinal niche, as the species is strictly localized within a narrow elevational range. Its distribution is concentrated at a consistent altitude of approximately 800 m AMSL, with the minimum, mean, and maximum elevation values all converging at this precise level. This lack of altitudinal variance suggests that the plant is highly specialized to the specific environmental conditions, such as temperature, humidity, and atmospheric pressure, found at this particular height above mean sea level. Such a restricted vertical distribution indicates that Hydnocarpus kurzii occupies a very stable and specific ecological stratum within its habitat.

Elevational range max:

800 m AMSL

Life history

The life history of Hydnocarpus kurzii is characterized by its existence as a perennial species, ensuring long-term survival within its natural habitat. As a phanerophyte, its reproductive buds are elevated well above the ground on woody stems, a life form that is consistently maintained throughout its development. This plant maintains an evergreen deciduousness, retaining its foliage throughout the seasons and providing a stable canopy. Its biological structure is defined by its phanerophyte growth habit, which supports its sustained presence and continuous vegetative life cycle.

Deciduousness :

evergreen

Life form :

phanerophyte

Lifecycle :

perennial

Morphology

The morphology of Hydnocarpus kurzii is characterized by its stature as a woody tree, exhibiting a self-supporting growth form rather than acting as a climber or liana. This plant is a terrestrial species, functioning as an independent organism that does not exhibit parasitic or epiphytic tendencies. In terms of its physical dimensions, it reaches a mean height of approximately 15 m, with a maximum potential height of up to 16 m.

Physiology

The physiology of Hydnocarpus kurzii is characterized by a standard C3 photosynthetic pathway, utilizing the Calvin cycle to fix atmospheric carbon dioxide into organic compounds without the specialized carbon-concentrating mechanisms found in C4 or CAM plants. In terms of nutrient acquisition, the species does not function as a nitrogen fixer, meaning it lacks the symbiotic relationships with diazotrophic bacteria (such as Rhizobium or Frankia) required to convert atmospheric nitrogen into bioavailable forms, and instead relies on the uptake of nitrates and ammonium from the soil through its root system.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Hydnocarpus kurzii is characterized by specific physiological mechanisms and varying seed physical properties. In terms of its breeding system, the plant does not exhibit self-fertilization, as the process is noted to be absent, suggesting a reliance on cross-pollination mechanisms to ensure genetic diversity. The resulting seeds vary significantly in size, reflecting a wide range of developmental outcomes. The seed mass demonstrates considerable variability, with a recorded minimum mass of 0.45455 g and a maximum mass reaching up to 1.5748 g. On average, the seed mass for this species is approximately 1.014675 g, providing a baseline metric for its reproductive output.
