GENERAL FORMS

Fuunelform flower of 

 morning-glory. 



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 

 lipped or labiate. Each of the lips 



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 Labiatae. (Properly, labi- 

 ate means merely lipped, without 

 specifying the number of 

 lobes; l^ut if is commonly 



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 masJied, or person-lil-e) . 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
