THE CALYX AND COROLLA. 



[lesson 13. 



Bell-shaped, or campaniUate ; where a short and broad tube 

 widens upward, in the 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 Moi^iing-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 

 of Stramonium (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 entire, 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. 



266. 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 the 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 monosepalom (263, 

 that is, one-sepalled), or sometimes monophyUous, that is, one-leaved; 

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

 Fhlox, with salver-shapeii corolla. 209. Of Dead-Nettie (Lamium), with labiate ringent (or 

 gaping) corolla. 910. Of Snapdragon, with labiate pergonatc corolla. Sll. Of Toad-Flax, 

 with a similar corolla spurred at the base.
