Common name: yellow thistle

Taxonomic notes

There are three varieties: horridulum, magacanthum, and vittatum. Var. horridulum is the only variety with yellow flowers, but it may also have red and purple flowers. [1]

Description

A description of Cirsium horridulum is provided in The Flora of North America. This species is thistle-like and tends to resprout growing erect to about 1 meter. [2]

Distribution

C. horridulum is found in all the eastern coastal states from Maine to Texas, Tennessee, Arkansas, and Oklahoma. [3] The varieties may have differing ranges: variety C. horridulum is found throughout the species range, except Oklahoma and Arkansas, variety C. megacanthum is found only in the lower Piedmont and coastal plain, and the variety C. vittatum is isolated to the coastal plain. [1]

Ecology

Habitat

It has been found in pine-wiregrass woodlands, savannahs, pine-scrub oak woodlands, juniper-pine-palm woodlands, longleaf pine-turkey oak barrens, pine hills, cabbage palm hammocks, and along streams and marshes. This species has also been observed in human disturbed habitats such as roadsides, weedy fields, waste grounds, ligand fields, flat spoil areas, shallow watered ditches, pine plantations, and frequently mowed areas. Takes to the moister soil below longleaf pine-scrub oak forested sand hills and occurs in open light conditions in loamy sand or peat, loose sand, and drying loamy sand. Usually inhabits moist open areas between either drier or wetter conditions and may be present in well-drained uplands and limestone substrate. [2] Associated species include Pinus palustris, Quercus laevis, Melanthera, Eleocharis, Juncus, Xyris, and others. [2]

Phenology

This species has been observed flowering from March to October and fruiting from March through November. [2] The varieties may flower at different times: variety C. horridulum flowers April to June, variety C. megacanthum flowers March to June and variety C. vittatum flowers from February to August. [1] Kevin Robertson has observed this species flower within three months of burning. KMR The variety C. horridulum has produced natural hybrids with C. pumilum var. pumilum. [1]

Seed dispersal

Seeds are cypsela that are wind and bird dispersed. [1] According to Kay Kirkman, a plant ecologist, this species disperses by wind. [4]

Fire ecology

This species is able to grow in burned old fields.[2]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Cirsium horridulum at Archbold Biological Station. [5]

Apidae: Apis mellifera

Halictidae: Augochlorella gratiosa, Halictus poeyi, Lasioglossum nymphalis, L. pectoralis

Megachilidae: Lithurgus gibbosus, Megachile brevis pseudobrevis

Use by animals

This species is the larval host to the little metalmark (Calephelis virginiensis) and painted lady (Vanessa cardui) butterflies. [6]

Diseases and parasites

The leaf epidermis is surrounded by an internal and external cuticle, that reduces the likelihood of a pathogen entering the plan. [7]

Conservation and Management

Cultivation and restoration

Members of the Seminole Tribe have been said to use parts of this plant to make blowgun darts.[6]
