Botanical Identification

Ecology

The ecology of Coriospermum squarrosum is fundamentally defined by its specialization to unstable, xeric environments, specifically thriving within coastal or inland dunes and sandy substrates. As a plant adapted to sand-dominated landscapes, it occupies niches characterized by high permeability, rapid drainage, and potentially nutrient-poor soils. This habitat selection necessitates physiological adaptations to withstand periodic substrate movement and the physiological drought induced by the low water-retention capacity of sandy terrain. By colonizing these dunes, the species plays a functional role in stabilizing loose sediments and contributing to the gradual development of organic matter within these shifting ecological zones.

Habitat :

dunes, sand

Life history

The life history of Coriospermum squarrosum is characterized by an annual lifecycle, meaning the plant completes its entire developmental process—from germination and vegetative growth to flowering and seed production—within a single growing season. Following the dispersal of seeds, the plant emerges to establish its structure, focusing its biological energy on rapid growth and the development of its distinctive morphological features. Once it reaches maturity, the plant undergoes a reproductive phase, producing flowers and subsequent seeds to ensure the continuity of the species. After the successful completion of its reproductive cycle and the release of its progeny, the individual plant dies, leaving the next generation to begin the cycle anew in the following season.

Lifecycle :

annual

Morphology

The morphology of Coriospermum squarrosum is characterized by its growth form as a non-woody herb, functioning as an independent organism without parasitic tendencies. It exhibits a versatile ecological habit, ranging from terrestrial to semiaquatic and aquatic environments, while remaining a terrestrial epiphyte. The plant is a self-supporting herb that does not require climbing structures, as it maintains a self-supporting stature rather than acting as a liana or vine. In terms of physical dimensions, it is a relatively small species, with a plant height ranging from a minimum of 0.05 m to a maximum of 1 m.

Physiology

The physiology of Coriospermum squarrosum is characterized by a C3 photosynthetic pathway, indicating a standard carbon fixation process typical of many woody plants. Its leaf morphology features an elliptic-lanceolate form with entire margins and the presence of spines, although it lacks leaf thorns. The leaf architecture is further defined by a specific leaf area (SLA) that is consistently recorded at a value of 115.8216271 cm²/g, representing the minimum, mean, and maximum measurements for the species.

Reproduction

The reproduction of Coriospermum squarrosum is characterized by a specific seasonal flowering pattern that dictates its reproductive cycle. The flowering period is highly concentrated, with the onset of flowering occurring in August. This period concludes within the same month, as the flowering end is also recorded in August, indicating a relatively brief and synchronized blooming window. While the broader seasonal context allows for variable timing, the specific data indicates that the plant's reproductive activity is most prominent during this mid-to-late year transition.

Flowering time :

Aug
