THE FLOWER 



190 19T 19s 



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

 bell, "with a campanulate or bell-shaped 

 corolla; 197, a Phlox, with salver-shaped 

 corolla ; 198, Dead Nettle (Lamiiim) , with 

 labiate rhii/p/it (or gaping) corolla ; 199, 

 Snapdragon, with labiate pprsonate 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 



</ yf /^HT^ /I~\ T\ salver represented in old 



' I 1 / > R pictures, with a slender 



handle beneath (Figs. 

 191-103, 197). 



Bell-shnped, or cam- 

 panulate, wliere a sliort 

 and broad tube \Yidens 

 upward, in the shape of a 

 bell, as in Fig. 19U. 



Funnel - shaped, or 



funnel-form, gradually 

 .spreading at the summit 

 of a tube which is narrow 

 l)elow, ill the shape of 

 a funnel or tunnel, as 

 in the corcilla of the common Morning Glory and of the Datura 

 (Fig. 189). 



Tubular ; wlien prolonged into a tube, with 201 



little or no spreading at the liorder, as in the 

 calyx of Datura (Fig. 189). 



264. Altliough sepals and petals are 

 usually all blade or lamina, like a sessile 

 leaf, yet they may have a contracted and 

 stalklilfe 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 outgrowtli of tlie 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 Crow^n, 

 or corona. In Passion Flowers (Fig. 202) 

 the crown consists of numerous tlu'eads 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 bud and wrapped around the others. 



201-202. Crowns: 201, un- 

 guiculate (clawed) 

 petal of a Silene ; 

 with a two-parted 

 crown; 202, a small 

 Passion Flower, 

 with crown of slen- 

 der threads.
