Calamus

The Calamus (Acorus calamus) is a species in the genus Acorus. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical coniferous forests within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

common vincetoxicum

<em>Vincetoxicum hirundinaria</em>, commonly known as common vincetoxicum or white swallowwort, is a perennial herbaceous plant in the family Apocynaceae (subfamily Asclepiadoideae) that was historically distributed across much of Europe and western Asia. The species typically grew in dry calcareous grasslands, rocky slopes, scrubland, and open woodland edges, particularly on warm, south-facing habitats with shallow soils rich in lime. <em>Vincetoxicum hirundinaria</em> is characterized by twining stems, opposite ovate leaves, and small, star-shaped white to pale yellow flowers produced in summer, followed by elongated seed pods that release wind-dispersed seeds with silky hairs. As a member of the milkweed subfamily, it historically served as a larval host plant for certain specialized butterfly species in Europe, contributing to local food web dynamics. The plant is notable for containing toxic alkaloids and glycosides that were historically used in folk medicine. Tragically, <em>Vincetoxicum hirundinaria</em> is currently assessed as Extinct by the IUCN, having been lost from the regions where it was previously documented. The factors contributing to its extinction likely include habitat destruction, agricultural intensification, and loss of calcareous grassland habitats across Europe. Biological traits such as average lifespan, plant dimensions, and precise weight remain poorly documented in historical records.
