Note 2523 — BOOK XXII. THE PROPERTIES OF PLANTS AND FRUITS.
John Bostock translation
The synonym of this plant is probably unknown. Dalechamps identifies it with the Sagittaria sagittifolia, C. Bauhin with the Centaurea calcitrapa, and Clusius, Belli, and Sprengel, with the Poterium spinosum. None of these plants, however, are prickly and aquatic, characteristics, according to Theophrastus, of the Stœbe: Hist. Plant. B. iv. c. 11. Fée considers its identification next to impossible.
