the Calyx, beset with hooks, forms the bur, as in 

 Arctium^ Lappa^ Engl. Bot. t, 1228 ; sometimes 

 hooks encompass the fruit itself, as in Xanthi- 

 um, and some species of Galium, particularly G. 

 Apa7-ine^ t. 816. Plants thus furnished are observed 

 by Linuceus to thrive best in a rank manured soil, 

 with which, by beini^ conveyed to the dens of wild 

 animals, they are most likely to meet. The Awns of 

 grasses answer the same end. Paipy fruits serve 

 quadrupeds and birds as food, while their seeds, of- 

 ten small, hard, and indii^estible, pass uninjured 

 through the intestines, and are deposited far from 

 their original place of growth, in a condition peculiar- 

 ly fit for vegetation. Even such seeds as are them- 

 selves eaten, like the various sorts of nuts, are hoarded 

 up in the ground and occasionally forgotten, or carried 

 to a distance, and in part only devoured. Even the 

 ocean itself serves to waft the larger kinds from their 

 native soil to far-distant shores. 



7. Receptaculum. The Receptacle is the common 

 base or point of connexion of the other parts of fruc- 

 tification. It is not always distinguishable by any par- 

 ticular figure, except in compound flowers constit^u- 

 ting the Linnsean class Syngenesia^ in which it is 

 very remarkable and important. In the Daisy, f. 

 208, Engl. Bot; t. 424, it is conical ; in Chrysanthe- 

 mum^ t. 601, convex ; in others flat, or slightly con- 

 cave. Picris, t. 972, has it naked, that is destitute of 

 any hairs or scales between the florets or seeds ; Car- 

 duus, t. 675^ hairy ; Anthemisy t, 602, scaly ; and
