Echinospermum strictum, N. ab E. E. caule stricto superne stricte ramoso foliisque lanceolatis callosis et patenti-pilosis, corollæ tubo calyce breviori, glochidibus nucum brevibus marginalibus serie simplici dispositis. ʘ (Rochelia nov. sp., Nutt. Mscp. Torr. in Ann. Lyc. Noveborac. II., p. 226, n. 300?).
This species may be easily distinguished by the characters indicated, from E. lappula and patulum, Lehm.

Both plants contain in the bark of their roots the same red dye as the officinal roots of the Alcanna tinctoria.
