Taxonomic notes

Synonyms: Sida carpinifolia Linnaeus f.; S. ulmifolia P. Miller

The specific epithet means sharpened to a point, in reference to the tip of the leaves.[1]

Description

Erect branched suffrutex up to 1 meter tall, rarely taller. Green stems, mostly hairless to stellate-hairy, particularly on younger parts. Leaves more or less narrowly lanceolate, 2-6(10) cm long; apex acute; base obtuse to rounded, hairless to sparsely stellate-hairy; margin regularly serrate; petiole c. 2.5 mm, pubescent. Stipules linear, usually longer than the petiole. Flowers axillary, solitary or 2 together. Calyx 6-8 mm long, somewhat angular, saucer-shaped, hairless, lobed to the middle; petals as long as calyx, yellow. Mericarps 5-6, c. 4 mm long, birostrate, grooved between the awns.[2]

Distribution

Distributed from South Carolina throughout Florida and west to Mississippi.[1]

Ecology

Habitat

Occurs in dry and moist deciduous forests.[1] In Northern Australia, it is classified as an invasive species and dominates improved pastures, disturbed areas and roadsides.[3]

Phenology

Flowers are borne singly or in small clusters in the leaf forks on short stalks. Flowers have 5 yellow petals and 5 sepals.[4]

Seed dispersal

Seeds have two sharp awns that easily attach to animals and clothing.[5]

Seed bank and germination

Seeds have an innate dormancy period, the embryo requiring a post-ripening period of 1 to 3 months at high temperatures before germinating.[5]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Sida acuta at Archbold Biological Station:[6]

Halictidae: Augochlorella gratiosa

Conservation, cultivation, and restoration

In Northern Australia, it is considered an invasive species. It dominates improved pastures, disturbed areas, and contaminates agricultural produce.[4]
