leaves witli their edges distinct or united, usually green, but sometime* 

 highly colored. The calyx leaves are called sepals. 



401. Corolla is a Latin word signifying a little crown, applied to 

 the interior envelop of the flower. It consists of one or more circles 

 of leaves, either distinct or united by their edges, usually of some other 

 color than green, and of a mqre delicate texture than the calyx. Its 

 leaves are called petals. 



402. Perianth {nngi, around, 6iv6og, flower) is a word in common 

 use to designate the floral envelops, as a whole, without distinction of 

 calyx and corolla. It is used in description, especially when these two 

 envelops are so similar as not to be readily distinguished, as in the tulip, 

 lily, and the cndogens generally ; also where only one envelop exists, as 

 in Phytolacca, elm, etc. (259, per.) 



403. The essential flokal organ's stand within the circles of tho 

 perianth, and are so called because they are the immediate instruments 

 in perfecting the seed and thus accomplishing the final purposes of the 

 flower. These organs are of two kinds, perfectly distinct in position 

 and office ; viz., the stamens and the pistils. 



404. The stamens are those thread-like organs situated just within 

 the perianth and around the pistils. Their number varies from one to 

 a hundred or more ; but the most common number is Jive. Collec- 

 tively they are called theandracium (dvdpEg* stamens, oiko^, a house). 



405. The pistils (called also carpels) oecupy the center of the 

 flower at the absolute terminus of the flowering axis. They are some- 

 times numerous, often apparently but one, always destined to bear the 

 seed. Collectively they arc called the gyncecium {jvvfj, pistil, olicog).
