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 sea-lavender

<em>Limonium vulgare</em>, the common sea lavender, is a perennial halophytic plant in the family Plumbaginaceae, order Caryophyllales, native to saltmarshes and coastal mudflats of Europe and North America. This species is a characteristic component of mid-marsh vegetation zones, thriving in the periodically inundated, saline soils of estuaries and tidal flats. It produces dense clusters of small, lilac-purple flowers on branching stems from late summer onward, providing an important nectar source for pollinators. Critically, <em>Limonium vulgare</em> is classified as Endangered by the IUCN, reflecting severe population declines driven by saltmarsh loss, coastal development, sea-level rise, and agricultural conversion of intertidal habitats. Its restricted habitat specificity makes it particularly vulnerable to coastal modification. Conservation efforts for this species focus on protecting and restoring saltmarsh ecosystems across its declining range. Biological traits for this species remain poorly documented in the scientific literature, including comprehensive quantitative data on individual lifespan, precise plant dimensions, and dietary ecology, though its photosynthetic, halophytic strategy and pollinator relationships are recognized aspects of its biology.
