and if they are united together so as to form a tube, 

 as in the florets of the Dandelion, they are said to 

 l>e Syngenesious. 



The figure of the anther is linear, as in Magno- 

 lia ; oblong, as in the Sedum ; oval, as in Fuschia ; 

 globular, as in the Lime-tree ; kidney-shaped, as in 

 Fox-glove ; peltate, as in the Yew-tree ; forked, as 

 in the Grasses ; arrow-shaped, as in the Crocus ; or 

 horned, that is terminating in two long awns, as in 

 the Heaths. The size of the anthers is estimated 

 by comparison with that of the filaments, con- 

 sidered as being longer, shorter, or of the same 

 length. The surface is smooth, as in the Grasses ; 

 or pubescent, as in Acanthus ; or bearded, as in 

 Verbascum ; or beset with glandular particles, as in 

 Leonurus ; or furnished with longitudinal angles 

 or furrows, as in the Rose and Ash. The structure 

 of the anther is unilocular, that is consisting of one 

 cell, as in Mercury ; or bilocular, that is consisting 

 of two cells, as in the Orchis ; or tetralocular, that 

 is consisting of four cells, a case that occurs but 

 rarely, as in Tetratheca.* In the Contorts and 

 a few of the Orchidca the anthers are solid. 

 Which But where the anthers consist of cells, as in most 

 the poikn. cases, they contain also a fine powder, which 

 botanists denominate the pollen, and which at the 

 period of the maturity of the flower bursts its in- 

 teguments and explodes, the integuments assuming 

 soon after a shrunk and withered appearance. In
