INTRODUCTION TO BOTANY. xix 



which the seeds are fixed along one suture or seam only ; it is 

 usually membranaceous ; for example, the j^ea. See Plate, 

 140. 



9. The Cone, (strobile,) is a catkin, composed of woody 

 scales, usually opening, and has a seed at the base of each 

 scale; for example, the^r. See Plate, 146. 



VI. The SEED. See its parts described in the physiolo- 

 gical part of this Introduction further on. 



VII. The RECEPTACLE, (see plate, 154, flat recept. 

 1 55, conical recept. :) it is the base by which the other six parts 

 of fructification are connected. It is called 1. propel', that is, 

 a peculiar recept., when it appertains to one fructification 

 only ; and this has the name of — 



1. A receptacle of the fructification, when it is common to 

 both flower and fruit, that is, embraces the corolla and 

 germen. 



2. Receptacle of the flower, when it is the base, to which 

 the parts of the flower only, exclusive of the germen, are 

 fixed. 



3. Receptacle of the fruit, that is, that of the fruit only, 

 distant from the receptacle of the flower. 



4. Receptacle of the seeds, the base to which the seeds are 

 fixed; for example, j9/;e«5aw^'5-ej/^, (adonis. 



5. A common receptacle, that is, one connecting several 

 florets, or distinct fructifications, so that if any one of them be 

 removed, an irregularity is occasioned ; for example, in the 

 umbel, cyme, compound jlo'wers. The receptacle may be naked, 

 that is, entirely smooth, or chaffy, bristly, &c. 



Of the different kinds of Flowers, 



I. Simple flowers have not any part of the fructification 

 common to many florets : a simple flower is opposed to that, 

 which is made up of several florets. 



II. Aggregate flowers, may be thus explained : when 

 several florets are so combined by the intervention of some 

 part of the fructification, that taking away one of them 

 destroys the uniformity of the whole. 



Aggregate flowers are connected by the receptacle, or
