TI1K ]' LOWER. 



the Sage and Mint belong. Such flowers are 5-merous, and 

 have two memliers specially united to form one lip, and three in 

 the other. The odd sepal being posterior (or next the axis of 

 inflorescence), and consequently the odd petal anterior, the calyx 

 has its lower lip of two sepals and its upper of three ; while tin- 

 corolla has its upper lip of two petals and its lower of three. 

 But in Lcguminosit, where the calyx is sometimes bilabiate, and 

 \\IMTC the odd sepal is anterior (or toward the bract), this is 

 reversed, and two sepals or lobes of the calyx form the upper 

 lip and three the lower. A bilabiate corolla is 



JH/it/t'itt, that is gaping or open-mouthed, when the throat is 

 freeby open, as in Lamium, Fig. 479 ; 



Personate, or masked, when the throat is closed, more or less, 

 by a projection of the lower lip called the PALATE, as in Antir- 

 rhinum and Linaria, Fig. 480, 481. 



452. Of regular forms, there are the following, beginning with 

 that having least tube : 



fiotate, or Wheel-shaped (Fig. 475, 476), widely spreading from 

 the very base, or from a short and inconspicuous tube. 



Crater if orrn, or Saucer-shaped, like rotate except that the broad 

 limb is cupped by some upturning toward the margin. 



Hypocrateriform , or rather (not to mix Latin and Greek) 

 Hypocraterimorphous, in English Salverform, when a rotate or 



saucer-shaped limb is raised on a 

 slender tube which does not much 

 enlarge upward ; that is, where a long 

 and narrow tube abruptly expands 

 into a flat or flattish limb, as in 



Fig. 478. 



In Fig. 472-474 arc seen 



salverform corollas with somewhat 

 more upwardly dilated (friuiipet- 

 shaped) tube. The salver or //>//><)- 

 craterium, which the name refers to, 

 with a stem or handle beneath, is now 

 to be met with only in old pictures. 



7'n/i/i/fir. when strictly used, denotes 

 a gamophyllous perianth with limb 

 inconspicuous in proportion to the 

 tube, as in Trumpet Honeysuckle, or as Fig. 472-471 would be 

 if the limb were much diminished or wanting. But it is some- 

 times used in the sense of having a conspicuous tube. 



Kl<!. 482. C:ily\ .-mil funnelform (infundibuliform) corolla of a common Morning- 

 Glory, Ipomoea purpurea.
