Lithospermum incisum is a species of flowering plant in the borage family. It is known by several common names, including fringed gromwell, fringed puccoon, narrowleaf stoneseed, narrowleaf puccoon, and plains stoneseed.
Description It is a hairy perennial herb growing from a narrow brown to black taproot and woody caudex. It produces a cluster of stems up to about long. The stems are lined with narrow, pointed leaves up to long.
Blooming from May to July, the slender, trumpet-shaped flowers are pale to bright yellow or gold. They may approach long, while the corolla face is 1 to 2 cm wide, its lobes sometimes ruffled. The smaller cleistogamous (closed) flowers are the main producers of seed. The fruit comprises four nutlets, each some long.
Distribution and habitat It is native to much of central and western Canada and the United States, where it can be found in dry open areas and foothills and pinyon–juniper woodland.
Cultivation Fringed gromwell reacts badly to being transplanted while actively growing, the leaves often turning black. It is less damaged if transplanted when dormant, taking as much of the pencil sized roots as possible. They grow best in very sandy, well draining soils, though they do grow in soils with some loam or clay.
Uses Used medicinally by Native Americans, the ground leaves roots and stems were rubbed on the limbs to reduce paralysis.Kelly Kindscher, Medicinal Wild Plants of the Prairie: An Ethnobotanical Guide (Lawrence: University Press of Kansas, 1992) Among the Zuni people, a salve of the powdered root applied ceremonially to swelling of any body part. A poultice of root is used and decoction of the plant is taken for swelling and sore throat.Stevenson, Matilda Coxe 1915 Ethnobotany of the Zuni Indians. SI-BAE Annual Report #30 (p. 56) The powdered root mixed with bum branch resin and used for abrasions and skin infections. An infusion of the root is taken for stomachache and kidney problems.Camazine, Scott and Robert A. Bye 1980 A Study Of The Medical Ethnobotany Of The Zuni Indians of New Mexico. Journal of Ethnopharmacology 2:365-388 (p. 374)
The leaves are bound to arrow shafts, close to the point, obscured by sinew wrapping and used in wartime.Stevenson, p.93
