which the pistil-queen and her stamen-courtiers are seated, with 

 winged sails on either side 

 and a banner floating above 

 them. 



848. Separate Petals and 

 Sepals are usually described 

 in the terms applied to the 

 corolla ; they are calcarate, 

 saccate, etc. In the Colum- 

 bine and Dutchman's Breeches 

 the petals are Cucullate, or 

 hooded. In some of the 

 Pinks they are Fimbriate, or 

 fringed ; here, too, they are 

 Unguiculate, or clawed. In 

 the Balsams (Fig. 164) one 

 sepal is prolonged into a 

 spur.

dular enlargements or ap- 

 pendage.5 in which the 

 sweets of most honey- 

 bearing flowers are se- 

 creted. The term was for- 

 merly applied to the spurs 

 of flowers like the Violet, 

 Balsam, etc., because they 

 contain these glands; but 

 it is now restricted to the glands 

 themselves. Nectaries are usu- 

 ally developed from the torus, 

 hut often from any other part of 

 the flower. "When on the corolla, 

 they are generally at the base 

 of the petals, on their inner face; 

 sometimes sessile, as in the Crown 

 Imperial; sometimes on stalked 

 hairs, making a lovely fringe, as in 

 the Broom-rape (Fig. 159, d). Very 

 often the nectary is only a glandu- 

 lose couch, as in the spur of the 

 Columbine petal.
