GENEKAL FOKMS

a wide -flaring limb, when it is said to be funnelform, 



as in morning-glory (Fig. 217) and pumpkin. If the tube 



is very narrow and the limb stands 



at right angles to it, the corolla is 



salverform, as in phlox (Fig. 218). 



If the tube is very short and the limb 



wide -spreading and nearly circular in 



outline, the corolla is rotate or wheel- 



shaped, as in potato (Fig. 219). 



273. A gamopetalous corolla or 

 gamosepalous calyx is often cleft in 

 such way as to make two prominent 



parts. Such parts are said to be 2 n. Funnelform flower of 

 lipped or labiate. Each of the lips morning-glory. 



or lobes may be notched or toothed. 

 In 5-merous flowers, the lower lip is 

 usually 3-lobed and the upper one 

 2-lobed. Labiate flowers are char- 

 acteristic of the mint family (Fig. 

 197), and the family therefore is 

 called the Labiatas. (Properly, labi- 

 ate means merely lipped, without 

 specifying the number of lips or 

 lobes; but it is commonly used to 

 designate 2 -lipped flowers.) Strongly 2 -parted 

 polypetalous flowers may be said to be labiate ; 

 but the term is oftenest used for gamopetalous 

 corollas. 



274. Labiate gamopetalous flowers which are 

 closed in the throat (or entrance to the tube) 

 are said to be grinning or personate (personate 

 means mas bed, or person- like). Snapdragon is a 

 typical example (Fig. 220); also toad-flax or 



butter -and -eggs (Fig. 211), and many related plants. 

 Personate flowers usually have definite relations to insect
