Description

C. ashei is a perennial, aromatic shrub with linear leaves arranged in opposite clusters.[1] [2] The bisexual flowers are pinkish-purple.[2][3]

Distribution

Ecology

Habitat

C. ashei is endemic to the Florida central highlands and southeastern Georgia, it occurs in pine-oak scrub ridges, and in Ceratiola scrubs.[2][4] It thrives in open areas of pine scrubs and disturbed sites such as abandoned fields, roadsides, and fire lanes.[2][5] Associated species include Osmanthus megacarpus, Ilex cumulicola and, Ceratiola ericoides.[4]

In order to reduce competition, C. ashei releases allelopathic compounds that prevent germination of other species' seeds, creating un-vegetated patches of sand.[6]

Phenology

Flowers and fruits have been observed January through June.[4]

Fire ecology

Fire has been observed to kill all adult C. ashei individuals.[7] Seedling frequency increases around ten months post-fire, with seedling probably established from seeds stored in a seed bank due to the absence of adult individuals.[7]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Calamintha ashei at Archbold Biological Station:[8]

Apidae: Apis mellifera, Bombus impatiens, Epeolus erigeronis, Epeolus zonatus

Halictidae: Agapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa, Halictus poeyi, Lasioglossum nymphalis, L. puteulanum

Megachilidae: Anthidiellum notatum rufomaculatum, A.perplexum, Coelioxys germana, Hoplitis truncata, Lithurgus gibbosus, Megachile brevis pseudobrevis, M. campanulae, M. exilis parexilis, M. georgica, M. inimica, M. mendica, M. Megachile petulans, M. policaris, M. rugifrons, M. texana, Osmia calaminthae

Conservation and management

Controlled burning is important for management of C. ashei. It is also important to open the canopy and expose bare sand using methods such as clear cutting and root raking.[2]

Cultivation and restoration

Global rank: G3
