Taxonomic notes
Synonyms: Buchnera americana Linnaeus; B. longifolia Swartz (by misattribution); B. breviflora Pennell (by misattribution); B. elongata Swartz.[1]
Varieties: none.[1]
Description
The genus Buchnera are hairy perennials with erect, simple stems growing between 40 - 80 cm tall. The entire plant turns black when dried. The leaves are oppositely arranged, elliptic to ovate-lanceolate in shape, entire or irregularly serrate, and grow up to 3 - 7 cm long and 5 - 15 mm wide, and is reduced above. The inflorescence is an open spike with the flowers in the axils of opposite bracts and supported by 2 bractlets. The 3.5 - 5 mm long calyx tube is cylindrical with lobes 5, lanceolate in shape, slightly unequal, up to 1 mm or less long. The bilaterally symmetrical flowers are purple or white in color and form a tube with 5 petals bent abruptly at right angles. Up to 4 fertile stamens are present with anthers with only a single sac. The 5 - 6 mm capsule seed is ovoid or pyriform.[2]
Specifically, for Buchnera floridana, the leaves are not 3-veined or not as conspicuous are B. americana. The leaves are lanceolate to elliptic in shape. The flower tube grows up to 8 - 10 mm long and the petals grow up to 4 - 5 mm long.[2]
Distribution
Mostly restricted to the coastal plain.[3]
Ecology
Habitat
General habitats are pine savannas, seepage bogs, flatwoods, and sandy roadsides.[4] Other habitats include low lying swamp and sandy acidic pine and palm barrens.[5] This species has been observed in Everglades National Park.[6]
Phenology
B. floridana flowers and fruits all year.[6] Flowers are blue-violet or white and bisexual with a superior ovary.
Fire ecology
Thrives in fire-maintained pine graminoid ecosystems in strongly acidic soils.[3]
Herbivory and toxicology
B. floridana is noted to have poor forage value.[7] It is a host plant of Brevipalpus phoenicis, which vectors viral diseases like citrus leprosis.[8]
