54 OBJECT LESSONS IN BOTANY. 



94. Salver-form^ the tube suddenly spreading out in a 

 liorizontal border, as in Phlox, Petunia (Figs. 126, 145). 



95. Ticbular^ when the corolla is nearly all a slender tube 

 with a small border or none at all, as in the Trumpet Honey- 

 suckle (Fig. 146). 



96. Ligulate (from the Latin ligula, tongue), as if formed 

 by splitting the tubular on one side. The notches at the end 

 plainly indicate the number of united petals which compose 

 it, as also do the parallel seams. See the flowers of the Dan- 

 delion (Fig. 147), also of Cichory. 



97. Labiate (Latin labium, lip), resembles the mouth of an 

 animal. It is a very irregular corolla, having the petals of 

 dissimilar shape and dissimilarly united. See (Fig. 148) a 

 flower of Synandra, or Catmint, or Catalpa. In Fig. 149 

 (Snap-dragon), the mouth is closed and said to be ^ersonate^ 

 which means masked. 



LESSON XV. 



CONCERNING THE STAMENS. 



98. Safely infolded within the perianth, we flnd a number 

 of delicate, thread-shaped organs, quite unlike the sepals and 

 petals. They are arranged in one or more circles, and called 

 the essential organs, because they are absolutely necessary to 

 the perfection of the seed. 



94. Describe the salver-form. 95. The tubular. 96. Ligulate. 



97. Labiate. Now repeat tlie regular forms. Repeat tlie names of the 

 irregular forms. 



98. AVhere do we find the essential organs ? How arranged? Why are 

 they so called ?
