CLASS XII. ORDER IH.J ilUGAKIA. 735 



with veins. Stamens numerous, with slender aul-shuped Jilamenls, 

 and ovate two celled anthers. Styles numerous, becoming after 

 flowering much elongated, curved, remarkably jointed above the 

 middle, where it is feathered with yellowish stout hairs, which shortly 

 falls away, and leaves a hook at the extremity of the remaining style, 

 which now becomes a persistent awn to the liairy carpel. After ger- 

 mination the ovate head of carpels frequently becomes elevated above 

 the calyx on a round peduncle, which has a very remarkable ap- 

 pearance. 



Habitat. — Marshes, ditches, and wet places; frequent. 



Perennial ; flowering in June and July. 



This species possesses similar properties, and is used forthe same pur- 

 poses as the last. It is frequently cultivated as a border flower, and 

 often becomes double, in which stale it is sometimes found wild. The 

 remarkable variety, which is occasionally found, having small yellow 

 petals similar to those of G. urbanum ; but with all the other charac- 

 ters of the plant G. rivale seems to be an hybrid between the two. 

 There are but few plants whose structure and economy seems less 

 understood than this. The styles are at first short, and inclosed 

 within the flower; but almost as soon as the flower is expanded, 

 and the anthers have shed their pollen upon the stigmas, the styles 

 elongate apparently more from below the joint than above: at the 

 same time the receptacle is frequently elevated above the now withering 

 calyx and petals on a stalk, from half an inch to an inch long. Upon 

 examining the elongated style with a strong magnifying power, the 

 joint appears to be formed by the union of two hooks; the upper one 

 of a much firmer texture than the lower, and often feathery; the lower 

 is stouter, more cellular, and as the seeds become matured, the upper 

 feathery part falls off" at the joint, and leaves a hook at the extremity 

 of the remaining portion, by which it attaches itself to the coats 

 of animals, &c., and thus spreads itself for further increase by 

 another means than that which it would seem to have lost in the 

 feathery extremity, which seems only reserved until the seed is about 

 ripe, and then by falling away leaves it better furnished with the 

 means of becoming more generally distributed.
