The Seeds are only naked in such plants as the Yew and the 



Firs, which are, therefore, called Gyiiinospermia (naked-seeded). 



In other flowering plants they arc enclosed in the fruit, and if the 



fruit is indehisceiit they have commonly a brown bitter outer skin. 



The seeds of dehiscent fruits arc more often conspicuously 

 coloured as in the Spindle-tree (p. loS) ; and they 

 arc sometimes, as in the Willows, Poplars, Willow- 

 herbs, &c., furnished with tufts of hair, which aid 

 in their dispersal by wind. The most important 

 distinction among seeds for purposes of classifi- 

 cation is into dicof)Pedonoits, having two opposite 

 lobes or seed-leaves (cotyledons) with the primary 

 bud between them, add iiioiiocotvli'doiious, with 



only one such cotyledon. 



Other terms which are employed in the body of the work will 



be explained as they occur, or in the glossary at the end of the 



volume.
