Buchnera breviflora Pennell

Buchnera floridana, the Florida bluehearts, is a species of flowering plant in the family Orobanchaceae.[2] It is native to the southeastern USA, Texas, eastern Mexico, Belize, Guatemala, Panama, and most of the Caribbean islands.[1] A hemiparasitic biennial, it is found mostly in wet areas such as open pinelands, flatwoods, and pitcher-plant bogs of the Gulf Coastal Plain.[2]

Description

[edit]

B. floridana is a hairy perennial with simple, erect stems that grow between 40-80 cm tall. The oppositely-arranged leaves are elliptic to ovate-lanceolate in shape with entire or irregularly serrate margins. The leaves grow 5-15 mm wide and 3-7 cm long. Unlike Buchnera americana, the leaves are not 3-veined.[3]

The inflorescence of B. floridana is an open spike with bilaterally symmetrical flowers that are purple or white in color. The flowers have 5 petals that form a tube and bend abruptly at right angles. There are up to four fertile stamens, each bearing anthers with a single pollen sac. The capsule seed is 5-6 mm in size and ovoid or pyriform in shape.[3]

Ecology

[edit]

B. floridana is mostly restricted to the coastal plain of the southeastern United States. Habitats include pine savannas, flatwoods, seepage bogs, and sandy roadsides[4]

B. floridana is considered to be of low forage value.[5] It serves as a host plant for Brevipalpus phoenicis, which vectors viral diseases such as citrus leprosis disease.[6]
