Description
Crocanthemum carolinianum is a perennial herbaceous species.
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[1].
Specifically, for Crocanthemum carolinianum species, the roots have tuberous thickenings, the stems grow 1-3 dm tall, are pilose, arising from a basal rosettes of leaves. The leaves are widely elliptic to obovate, or nearly lanceolate, growing 2-5 cm long, and 0.7-2 cm wide, stellate pubescent on both surfaces, with longer trichomes above; basal leaves are often somewhat erose,usually larger than the stem leaves; the petioles grow 1-3 mm long. The cleistogamous flowers are absent. The chasmogamous flowers are solitary, are opposite a leaf (or appearing internodal). There are 6 sepals, the outer 3 linear, growing 5-10 mm long, are acute to acuminate, stellate pubescent; the petals growing 1.5-2 cm long. The capsules are globose to subglobose, growing 7-9 mm long. The seeds are reddish black in color, papillose, and growing 0.8-1 mm long[1].
