THE CALYX AND COROLLA. 



[lesson 15. 



Bell-shaped^ or campayiulate ; where a sliort and broad tube 

 widens upward, in tlie shape of a bell, as in Fig. 207. 



Funnel-shaped, or funnel-form ; gradually spreading at the sum- 

 mit of a tube which is narrow below, in the shape of a funnel or 

 tunnel, as in the corolla of the common Morning-Glory, and of the 

 Stramonium (Fig. 199). 



Tubular ; when prolonged into a tube, without much spreading at 

 the border, as in the corolla of the Trumpet Honeysuckle, the calyx 

 bf Stninionium (Fig. 199), &c. 



•265. In most of these cases we may distinguish two parts; namely, 

 the tube, or the portion all in one piece and with its sides upright or 

 nearly so ; and the border or limb, the spreading portion or summit. 

 The limb may be entii*e, as in Fig. 203, but it is more commonly 

 lobed, that is, partly divided, as in Fig. 202, or parted down nearly 

 to the top of the tube, as in Fig. 208, &c. 



2G6. So, likewise, a separate petal is sometimes distinguishable 

 into two parts ; namely, into a narrowed base or stalk-like part (a? 

 in Fig. 200, where this part is peculiarly long), called the claw, and 

 a spreading and enlarged summit, or body of the petal, called the 

 lamina or blade. 



267. When parts of the same set are not united (as in the Flax, 

 Cherry, &;c.. Fig. 212-215), we call them distinct. Thus (he sepals 

 or the petals are distinct when not at all united with each other. As 

 a calyx with sepals united into one body is called monosepalous (263, 

 that is, one-sepalled). or sometimes monophyllous, that is, one-leaved ; 

 so, on the other hand, when the sepals are distinct, it is said to be

 Phlox, with sah'er-phapod corolla. 209. Of Dead-Nettie (Lamium), with labiate ringent (or 

 gapinc) corolla. 210. Of Snapdragon, with labiate personate corolla. 211. Of Toad-Flax, 

 with a similar corolla spurred at the base.
