Mecardonia (axilflower) is a genus of herbaceous plants in the family Plantaginaceae. 31 species have been described, [3] of which 12 are accepted. Its distribution is predominantly in South America, and South East United States, including Florida [4] [5] and Alabama [6] [7] but may be found as far north as Virginia. [8](see map) [9] Five species are found in Argentina [10] and three in the US. [11]
They are herbaceous procumbent glabrous plants. They are mostly blackened when they are dry. Their stems are 5–40 cm in length and they have 4-alate leaves. Ovate leaves 7–25 mm in length and 3–16 mm wide, with a crenate edge; petiolate. Solitary axillary flowers, pedicles 8-20 (-26) mm in length, basally bibracteolate; 5-lobed calyx, with unequal lobes, more or less free to the base, imbricate, the adaxial lobe widely lanceate to ovate, 5–9.5 mm long and 3–6 mm wide, slightly accrescent, the 2 middle lobes longer and overlapping, the 2 abaxial lobes nearly the same size as the adaxial and overlapping the middle lobes; 5-lobed corolla, 7–8 mm long, yellow with purple at the throat, bearded at the mouth; 4 fertile stamens. Ovoid fruit capsule, 5–7 mm long, loculicidal; ovoid, reticulated seeds. [12]
The genus was described by Ruiz & Pav., published in Florae Peruvianae, et Chilensis Prodromus 95. 1794. [12] [13] The type species is: Mecardonia procumbens Ruiz & Pav. The genus is named after Antonio Meca y Cardona, who founded the botanical gardens in Barcelona, in 1784. [14] [15] [16]
Rossow (1987) in his taxonomic revision of the genus, recognized ten species. A new species, M kamogawae, was identified in Argentina by Greppi and Hagiwara (2011).
Sold as an ornamental garden flower, such as Mecardonia Magic Carpet Yellow, as annuals in colder areas.
