Coreopsis bakeri, commonly called baker's tickseed[2] is a perennial, herbaceous, flowering plant in the Asteraceae family. It is endemic to Jackson County, Florida. It is closely related to Coreopsis lanceolata.[3]
Description
[edit]Coreopsis bakeri is a perennial herbaceous flowering plant that typically grows between 20 to 35 cm (7.9 to 13.8 in) tall. The linear to narrowly oblanceolate infolded leaves are 11 to 29 cm (4.3 to 11.4 in) long and 0.3 to 1.4 cm (0.12 to 0.55 in) wide. The ray florets are yellow with the toothed ligules being between 2 to 2.5 cm (0.79 to 0.98 in) cm long. The five-lobed disk florets are yellow and are between 3.5 to 5 mm long. The outer phyllaries are narrowly ovate, and are 6.5 to 8 mm long by 2.5 to 3 mm wide. The inner phyllaries are ovate and acute, and are 9 to 11 mm long by 3.5 to 4 mm wide.[4]
Similar species
[edit]Coreopsis bakeri is similar to a closely related species named Coreopsis lanceolata. The two species can be differentiated by their leaves; C. bakeri will have unlobed, infolded, linear-oblanceolate glabrous leaves while C. lanceolata will have flat, slightly pubescent, oblanceolate leaves that usually have basal leaf lobes.[4]
Distribution and habitat
[edit]Coreopsis bakeri is endemic to Jackson County, Florida. It grows on limestone glades.[4]
Conservation
[edit]As of November 2024[update], NatureServe listed Coreopsis bakeri as Critically Imperiled (G1) globally. This status was last reviewed in October 2021.[1]
Due to Coreopsis bakeri having a severely restricted range (upland limestone glades in Jackson County, Florida), it is threatened by mining, agriculture, development, and hybridization with Coreopsis lanceolata. There are nine known populations of C. bakeri.[4][1]
Taxonomy
[edit]Coreopsis bakeri was first named and described in 2015 by Edward E. Schilling.[5] The species is closely related to Coreopsis lanceolata.[4]
