THE FLOWER 



196-200. Corollas : 196, a Campanula or Hare- 

 bell, with a campauulate or bell-shaped 

 corolla ; 197, a Phlox, with salver-shaped 

 corolla ; 198, Dead Nettle (Lamium) , with 

 labiate ringent (or gaping) corolla ; 199, 

 Snapdragon, with labiate yjersonate co- 

 rolla : 200, Toadflax, with a similar 

 corolla spurred at the base. 



spreading border is raised on a narrow tube, from which it diverges 



at right angles, like the 

 salver represented in old 

 pictures, with a slender 

 handle beneath (Figs. 

 191-193, 197). 



Bell-shaped, or cam- 

 panulate, where a short 

 and broad tube widens 

 upward, in the shape of a 

 bell, as in Fig. 196. 



Fu nnel- shaped, or 



funnel-form, gradually 

 spreading at the summit 

 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 Datura 



(Fig. 189). 



Tubular ; when prolonged into a tube, with 



little or no spreading at the border, as in the 



calyx of Datura (Fig. 189). 



264. Although sepals and petals are 

 usually all blade or lamina, like a sessile 

 leaf, yet they may have a contracted and 

 stalklike base, answering to petiole. This is 

 called Claw, in Latin unguis. Unguiculate 

 petals are universal and strongly marked 

 in the Pink tribe, as in Soapwort (Fig. 

 190). 



265. Such petals, and various others, may 

 have an outgrowth of the inner face into an 

 appendage or fringe, as in Soapwort, and in 

 Silene (Fig. 201), where it is at the junction 

 of claw and blade. This is called a Crown, 

 or corona. In Passion Flowers (Fig. 202) 

 the crown consists of numerous threads on 

 the base of each petal. 



266. Papilionaceous corolla (Figs. 203, 204). — This is polypetalous, 

 except that two of the petals cohere, usually but slightly. It belongs 

 only to the Leguminous or Pulse family. The name means butter- 

 flylike ; but the likeness is hardly obvious. The names of the five petals 

 of the papilionaceous corolla are curiously incongruous. They are, 



The Standard or banner (vexillum), the large upper petal which is 

 external in the biid and wrapped around the others.

 der threads.
