Description
It has a vining habit, where some are large vines whereas other are small erect plants (FSU Herbarium). It is paraheliotropic.[1]
Clitoria mariana is a trailing, twining, perennial, herbaceous vine growing up to 0.5-1 m long with glabrous to short-pubescent stems. The leaves are pinnately 3-foliolate. The leaflets are entire, mostly ovate to lanceolate or ovate-oblong to somewhat elliptic, growing 2-7 cm long; glabrous above and glabrous or occasionally short-pubescent beneath, stipellate; stipules ovate-lanceolate to lanceolate, ca. 2-4 mm long, tardily deciduous, striate. The racemes are axillary, peduncles growing 0.5-4(6) cm long, usually shorter than subtending leaves, are 1-3 flowered; pedicels are usually glabrous or rarely short-pubescent, (2) 4-10 mm long, each subtended by a triangular to lanceolate, striate bract growing 1-3 mm long and with a pair of linear bractlets growing3-6 mm long at or near the summits. The calyx is usually glabrous or rarely short-pubescent, somewhere bilabiate. The tube is cylindric, growing 1-14 cm long, upper lobes are widely triangular, acute, growing 4-6 mm long, lateral lobes ovate-lanceolate, acuminate, grwoing 5-7 mm long, lowermost lobe lanceolate, acuminate, growing 6-8 mm long. The petals are pale blue or lavender in color, the standard are spurless, growing 4-6 cm long, and 3-4 cm wide. The wing petals are smaller and attahced to the strongly incurved keel petals. The stamens are monadelphous. The legumes are flattened, oblong-linear, growing 3-6 cm long; stipe elongate, growing 1-2 cm long, valves longitudinally twisting upon dehiscence. The seeds are sticky and adherent (Radford 1964).
Distribution
Ecology
Habitat
It occurs in frequently burned longleaf pine-turkey oak sandhills (FSU Herbarium), sand pine scrub (Entisols), [2] flatwoods (Spodosols) [3] and upland longleaf pine-wiregrass communities (Ultisols), as well as the margins of mixed hardwood communities (FSU Herbarium) and loblolly pine plantations. [4] It ranges from dry [5] to moist sandy areas (FSU Herbarium). It can live in partially shaded areas (54% ambient light conditions). [6] It can be found in longleaf pine flatwoods communities. [3] It is also found in loblolly pine communities. [4] It can also be found in sand pine scrub. [2] It thrives in frequently burned areas, and typically occurs in high light environments, but also tolerates partial shade (FSU Herbarium). Although it occasionally occurs in frequently burned old-field communities, it is more typical of native pine communities which have minimal soil disturbance. Associated species include Desmodium nudiflorum, D. ochroleucum, Quercus laevis, Q. stellata, Pinus palustris, P. echinata, Centrosema virginianum, Carya tomentosa, with other weeds, vines and trees in roadside ditches (FSU Herbarium).
Phenology
It flowers from May to August and fruits from September to October (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses being carried externally by vertebrates. [7]
Fire ecology
Because it was found in Henley Park plots which were burned every one to two years in the winter, it is fire-tolerant (Brewer and Cralle 2003). It resprouts quickly after fire, which can be supported by the fact that it resprouted within a month after fire in Pavon's study (Pavon 1995). It attained its peak in two-year rough plots at Henley Park, plots that had undergone two growing seasons since the last burn (Brewer and Cralle 2003). This is supported by Greenberg's study, which shows the peak percent cover to be 16 months after fire around 80% (Greenberg 2003).
Use by animals
It is a game-food plant (Cushwa 1966), so it is probably consumed by Gopherus polyphemus (Gopher tortoise) white-tailed deer, and bobwhite quail (Hainds et al 1999).
