54 FRUCTIFICATION. 



PI. 14, fig. S. Ex. Larkspur, Delphinium and Nas- 

 turtium, Trapieolum. 



Q. Cup-shaped. PJ, 13, fig. 6. Ex. Narcissus. 



3. Scale, (sqwama.) Ex. Buttercup, Ranunculus. 



4. Glandular, (glandulosumS) These actually 

 secrete honey, and are the most indubitable of all 

 nectaries. In the cruciform plants, as Cabbage, Tur- 

 nip, Mustard, Radish, Gilly-flower,. &c. they are four 

 green glands at the base of the stamens. 



Observation. In monopetalous corollas, the tube contains, and 

 probably secretes the honey. 



General observation. 1. There can be no doubt that the sole use of 

 the honey with respect to the plant is to tempt insects, who, in 

 procuring 1 it, fertilize the flower by disturbing- the dust of the 

 stamens, and even carry that substance from the barren to the fer- 

 tile blossoms, Smit h. 



2. In discriminating the genera, the nectary often furnishes the 

 essential character. 



III. Stamens. 



STAMENS, (stamina.') PI. 12, fig. 1, b. b. b. These 

 are situated internally as it respects the calyx and 

 corolla, and externally with respect to the pistils. They 

 are various in number in different flowers, from one to 

 some hundreds. 



The Stamen commonly consists of two parts. 



1. FILAMENT, (fiiamentum.^ PI. 12, fig. 3, b.; and 



2. ANTHER, (anthera) a, which is elevated upon 

 the filament. 



The filament is sometimes wanting, when the anther 

 is termed Sessile, (sessilis.) 



The ANTHER is generally of a membranous tex- 

 ture, consisting of two cells or cavities bursting longitu^ 

 finally at their outer edges, as in the Lily- In the Po- 

 tatoe, in the Kalmia, and some others, it opens by pores 

 at the summit. 



The POLLEN is a powder or dust, which is contained 

 by the anther and discharged chiefly in warm dry 

 weather, when the coat of the anther contracts and
