SYNGENESIA— POLYGAMIA-7EQU. Diotis. 403 



Germ, oblong, slender, between the spurs. Style thread- 

 shaped, the length of the corolla. Stigmas 2, spreading, 

 obtuse. Sccd-vcssel none but the unchanged calyx. Seed 

 oblong, compressed, tapering at the base, bordered at 

 each side with the compressed, obtuse spurs of the co- 

 rolla. Down none. Recept. convex, nearly globular, 

 small, beset with oblong, concave, downy-tipped scales, 

 nearly as tall as the flowers. 

 Only one species, a densely cottony, perennial, corymbose 

 herb, with simple crenate leaves, and tufted, yellow, dis- 

 coidjlowers. It is generally taken for the original an- 

 cient Gnaplialium of Dioscorides, being fre(|uent on all 

 the shores of the Archipelago ; and Tournefort, who con- 

 firms this opinion in his Voyage v. 1. 10, detected, with 

 great sagacity, an essential generic character in the 2 

 spurs of each Jloret, which form a sort of wings to the 

 seed. Gaertner, Desfontaines, and other able botanists, 

 have confirmed this, and I can no longer refuse to ad- 

 mit the genus, though its original name is transferred to 

 another well-known and very ample one, from which it 

 could not, without great inconvenience, be removed. 

 Diotis, invented by Desfontaines, well expresses the es- 

 sential character, of a pair of ears to the seed. Still I 

 cannot but wish that the habit were more distinct from 

 Santoli^ia.
