Tribe III. 



GRATIO'LEjE (this tribe contains plants agreeing with the 

 genus Gratiola in the characters given below.) D. Don, in edinb. 

 phil. journ. vol. 19. July, 1835. Calyx usually tubular, 5-cleft. 

 Corolla tubular, ventricose, sometimes personate ; limb 5- 

 lobed, bilabiate, or nearly equal. Stamens 4, didynamous, in- 

 closed, sometimes 2 of which are sterile ; cells of anthers di- 

 verging, distinct at apex. Stigma usually bilamellate. Capsule 

 often membranous, rarely subunilocular. Dissepiment mem- 

 branous, formed by the inflexed margins of the valves ; pla- 

 centas spongy, at length free. Seeds with a somewhat crusta- 

 ceous testa. Albumen fleshy Embryo almost the length of 

 the seed. Herbs, rarely under-shrubs, natives of the temperate 

 parts of the globe ; or in marshy places within the tropics. 

 Leaves opposite or verticillate. Flowers axillary or terminal, 

 usually yellow or purple. 



% 1 . Stamens 4, 2 of which are sterile. 



XIV. GRATPOLA (from gratia, grace ; on account of the 

 supposed medicinal good qualities.) R. Br. prod. p. 435. 

 Lam. ill. 116. f. 1. Gratiola species of Lin. and other au- 

 thors. 



LIN. SYST. Didndria, Monogynia. Calyx 5-parted. Corolla 

 tubular, bilabiate ; upper lip 2-lobed : lower one trifid, equal. 

 Stamens 4, 2 of which bear anthers, and 2 or 3 are sterile. 

 Stigma bilamellate. Capsule 4-valved ; dissepiment contrary, 

 separable but slowly from the inflexed edges of the valves. 

 Glabrous herbs, with opposite leaves, and axillary, usually bi- 

 bracteate flowers. 



* Species natives of Europe. 



1 G. OFFICINA'LIS (Lin. spec. 24.) glabrous ; leaves lanceo- 

 late, serrated, somewhat 3-nerved ; flowers pedunculate. If. H. 

 Native of France, Switzerland, Denmark, &c., in humid places.

 t. 411. Root creeping, articulated. Stem tetragonal above. 

 Leaves decussate, 3-5-nerved, sometimes entire. Corollas 

 whitish or pale yellow, striated with purple. Fertile filaments 

 bearded. Calyx often 7-cleft. Capsule ovate, acuminated. The 

 whole plant has a strong, bitter, nauseous taste, and is much 

 recommended by several eminent medical writers in cases of 

 dropsy. It is a powerful cathartic, but is said generally to 

 occasion vomiting. On account of its bitterness cattle reject it ; 

 insomuch that Haller assures us that there are meadows about 

 Yverdun entirely useless from the abundance of it.
