and the seeds have ripened, these bracts flare open, making a wide- 

 mouthed urn from which the ripened seeds are shaken by the winds; and 

 after the seeds are gone, 

 the white fuzz of their 

 empty cases remains at 

 the bottom of the urn. 

 The seed is plump and 

 shining, with a short 

 fringe of pappus around 

 the top and a contracted 

 place at one side near 

 the base where it grew 

 fast to the receptacle; 

 for these seeds are not set 

 on end, as are those of 

 the sunflower. The short 

 pappus is hardly suffici- 

 ent to buoy up the seed, 

 and yet undoubtedly 

 aids it to make a flying 

 jump with the passing 

 breeze.

THE SALVIA, OR 

 SCARLET SAGE 



Teacher's Story 

 The flower story of 

 the sage is so peculiar 

 that Darwin has used it 

 to illustrate the mechan- 

 isms present in some 

 flowers which the visit- 

 ing insects must work in 

 order to get the nectar. 

 The scarlet sage, which 

 gladdens our flower beds 

 during the summer and 

 autumn with its bril- 

 liance, has as interesting 



The salvia, or scarlet sa^e, showing the bracts still 

 present above and falling as the flowers open.
