76 AN INTRODUCTION 



of the corolla in pairs ; in each of which respectively 

 the two antherae approach each other. 



PTSTILLUM The germen commonly above the 

 receptacle. The style single, filiform, bent in the 

 same manner as the filaments, usually placed within 

 them, a little exceeding them in length, and slightly 

 curved towards the summit The stigma for the 

 most part ernarginate. 



P EK i CA n P i u M Either wanting (see the first order) 

 or, if present, usually bilocular (see the second 

 order). 



SEEDS If no pericarpium, four, lodged within the 

 hollow of the calyx, as in a capsule; but if there be 

 a pericarpium, more numerous, and fastened to a re<- 

 ceptacie placed in the middle of the pericarpium. 



The flowers of this class are for the most part al- 

 most upright, but inclining a little at an acute angle 

 from the stem, that the corolla may more easily 

 cover the antherae, and that the pollen may fall on 

 the stigma, and not be soaked with the rain. The 

 essential character is in the four stamina ; of which 

 the two nearest are shorter, and all four close to 

 each other, and transmitted with the single style of 

 the pistillum through a corolla that is unequal. 



The Orders of this class are two, viz. 



ORDER!. GYMNOSPER&IA*, comprehending such 

 plants as have naked seeds. This order has these 

 farther characters, viz. the seeds four, excepting Phry- 

 ma, which is monospermous ; and the stigma bipartite 

 and acute, with the lower lacinia reflected. It contains 

 thirty-six genera distinguished into, 1 . Such as have 

 the calyx subquinquefid ; of which there are twenty, 

 viz. Perilla, Leonurus, Glecoma, Bystropogon, Hys- 



* The plants of this order are scented, and arc accounted 

 cephalic and resolvent. The virtue is in the leaves. They are 

 the Labiati (lip'd plants) of Tournefort ; and Verticillatat 

 (plants that flower at the joints) of Ray, Hist. Plant. 508.
