Botanical Identification

Ecology

The ecology of Muraltia spinosa is characterized by its specific vertical distribution within its native landscape, occupying a distinct altitudinal niche. This species thrives within an elevational range that begins at a minimum of 520 m AMSL and extends up to a maximum of 1035 m AMSL. This specific range suggests that the plant is adapted to mid-elevation environments, where it likely interfaces with particular microclimates, soil compositions, and moisture levels found within these specific topographical limits.

Elevational range max:

1035 m AMSL

Elevational range min:

520 m AMSL

Life history

The life history of Muraltia spinosa is characterized by its classification as a perennial species, meaning it maintains its vegetative structures and biological functions over many years rather than completing its cycle in a single season. As a long-lived woody plant, it establishes a robust presence in its natural habitat, undergoing continuous growth cycles that allow it to persist through various environmental conditions. This perennial nature enables the plant to invest significant energy into its structural development, including its characteristic thorny branches, which support its long-term survival and reproductive capabilities across multiple growing seasons.

perennial

Morphology

The morphology of Muraltia spinosa is characterized by its growth form as a woody shrub, exhibiting a self-supporting structure that does not require climbing assistance. As an independent organism, it functions as a terrestrial species rather than an aquatic, semiaquatic, or epiphytic plant. The plant maintains a compact stature, with a height ranging from a minimum of 0.4 m to a maximum of 1.2 m, resulting in an average plant height of approximately 1 m.
