Description
C. corymbosum is a perennial species with alternate, simple leaves.[2] It has tomentose stems.[3]
Generally, for the Crocanthemum genus, they are erect, heraceous or suffrutescent perennials with alternate, stellate-pubescent leaves. There are two types of flowers, chasmogamous and cleistogamous. Chasmogamous flowers are on the pedicels that elongate to usually more than 1 cm long with large showy, tallow petals; there are numerous stamens and large sepals. The cleistogamous flowers are on the pedicels are usually less than 3 mm long, where the petals are absent, the stamens are few and the sepals are smaller than those of the chasmogamous flowers. The sepals are in 2 whorls, the outer are narrower than the inner. The capsule is 3-locular. [4]
Specifically, for Crocanthemum corymbosum species, the roots have tuberous thickenings, the stems grow 1.3-5 tall, stellate canescent. The basal leaves are absent; the stem leaves 10-20, elliptic to oblanceolate, growing 1.5-3 cm long, and 5-10 mm wide, stellate-canescent above, tomentose beneath. The petioles 1-3 mm long. The cleistogamous flowers in compact terminal cymes; pedicels usually less than 5 mm long; the sepals and capsules 3-4 mm long. The chasmogamous flowers on pedicels 1-2 cm, scattered in the compact, the cleistogamous infloresence, or arising from its base; petals ca. 1 cm long; sepals and ovoid capsule, 5-7 mm long, pilose. The seeds are reddish brown in color, 1-1.2 mm long.[4]
Distribution
Ecology
Habitat
It can been found in upland, well-drained sandy habitats, such as scrubby flatwoods (Pearson 1954).[5] It has been observed growing in drying sand (FSU Herbarium). Associated species include Quercus virginiana, Q. myrtifolia, Q. pumila, Q. chapmanii, Serenoa repens, Osmanthus americanus, Vaccinium myrsinites, Aristida strica, and Trilisa odoratissima" (Pearson 1954).
Phenology
The canary yellow flowers bloom March through June.[6]
Pollination and use by animals
Crocanthemum corymbosum was observed at the Archbold Biological Station to host sweat bees such as Lasioglossum nymphalis (family Halictidae).[7]
