Featured Plants - Florida's Chaffhead and Vanillaleaf, Carphephorus spp.
 

Cross section of head of Carphephorus spp.Asteraceae

Medium to large perennial herbs usually with a single erect leafy stem, from 0.5 to 1.5 m tall, from a thickened base or rhizome. Stems may be smooth, hairy, or with glands. Leaves usually in rosettes; linear, needle-like or lanceolate to oblanceolate; stem leaves alternate, essentially sessile, much smaller than basal leaves. Flowers in heads, arranged in a flat-topped, or broad cylinder inflorescence; individual heads are composed of disk flowers only, surrounded by bracts (phyllaries) in 2 to 6 rows, flowers with pink or purple corollas and with a bract (chaff) at the base. Fruit a cone-shaped achene, broadest at tip, 10-angled, topped by a pappus of numerous fine bristles.

 At a glance: Herbs with a single, erect leafy stem from a basal rosette of leaves, the stem leaves alternate, small; inflorescences flat-topped or short cylindrical; heads rayless, with pink to purple disk flowers. Carphephorus is similar to Liatris, but the inflorescences are flat-topped or broadly cylindrical (thyrsoid), heads not in long spikes or narrow cylinders as in Liatris.

There are five species of Carphephorus in Florida, of which four are wetland species. Carphephorus corymbosus (Nutt.) Torr. & Gray, the single upland species, is our only species with both relatively broad leaves and large heads (greater than 1 cm long).

Habitat:
UPLAND Carphephoruss corymbosus: Sandhills, dry to relatively wet pinelands.

FAC Carphephorus odoratissimus, C. paniculatus: Hydric to mesic flatwoods, wet prairies, seepage slopes, sometimes (C. odoratissimus) sandhills.

FACW Carphephorus carnosus, C. pseudoliatris: Hydric to mesic flatwoods, wet prairies, seepage slopes.

 

Distribution:
Carphephorus carnosus - Endemic to central peninsular Florida from Brevard and Martin Counties west to Charlotte and Lee Counties.

Carphephorus corymbosus - Throughout the peninsula, west to Taylor County in north Florida, and south to Monroe County.

Carphephorus odoratissimus, C. paniculatus - Throughout except southernmost counties (Broward, Dade, and Monroe Counties).

Carphephorus pseudoliatris - Northwest Florida from Wakulla and Liberty Counties west to Escambia County.
