THE STAMINA. 7 



ence: as is evident from the Ammania, Isnarda, Peplis, Ruellia 

 and Campanula, in all which the corolla is often found wanting, 

 bat not the calyx. 



That the calyx, as proceeding from the cortex of the plant, is 

 c6arser and thicker than the corolla, which is produced by the 

 soft, pliant, coloured liber, is obvious to every one. But there 

 are no limits determinable from any such circumstances, unless 



it be from the colour ; and even this is not sufficient : for the 



. / 



perianthium of the Bartsia is crimson-coloured ; and there are 



also many flowers whose corollas are coloured, when in the state of 

 flowering, but which afterwards harden and turn green, and re* 

 main on the plant like a calyx ; as for instance, the Helleborus 

 and Ornithogalum. The Euphorbia has likewise deceived 

 many, who have described it as monopetalous, taking the calyx 

 for the corolla. 



CHAP. IV. 



OF THE STAMINA* 



THE Stamina are the male part of the flower. JLinnctus defines 

 them as a "viscus of the plant, designed for the preparation of 

 the pollen ;" of which we shall speak presently. 



Each single stamen consists of two parts*, viz. 



1. Filamentum, the filament ox thread; which serves to elevate, 

 the anthera, or summit, and at the same time connects it with the 

 flower. 



2. Anthera, the summit itself; which 'contains within it the 

 pollen, and when come to maturity discharges the same. 



* This is not always the case, as some stamens are complete, having nothing but 

 the anther, as in the Canna Indica, Indian canna, &c. Editor.
