3. Can/nphillous, with long 

 lender claws protected by a tub- 

 ular calyx with an expanding 

 limb, as in the Pink (fig. 75) 

 When the claws are short the 

 flowers are called ahinaceous.

4. Cruciform are such as consist of 4 petals arranged op- 

 posite, or at right angles to each other, as the Turnip, Cab- 

 bage, 6ic. (tig. 76.) 



5. Papilionaceous consist of 5 petals of which the upper 

 is erect, more dilated than the others, and is called the vexil- 

 lum, {11, a.) the two lateral are at right angles with the vex- 

 illuni and of course parallel with each other and are called 

 the wings or oJcb, (tig. 77, b,) the two lower are shaped like 

 the wings and parallel with them, and cohere by their lower 

 margin and form the keel or carina, (lig. 77. c.) 



This form of the corolla is peculiar to the order Legumi- 

 naceac, including the Pea, Bean, &c. 



84. It very frequently happens that we find in examining 

 flowers, parts which we can refer to no organ with which we 

 have become acquainted. They appear to he distinct from 

 the calyx, corolla, stamens or pistils, and can be comprehend- 

 ed under none of these organs, although situated among them 

 and attached perhaps to them. All such parts are called ap- 

 pendages, and, from the variety of lorm they assume, much 

 confusion has been created in tlieir description, from the want 

 of uniform terms applied to them. 



Th"y have their origin eitli(!r from the corolla or stamenf. 

 Every appendage arising from the corolla is called a. paracorol- 

 la, an! if consisting of several pieces a /ame//a. VV lien one 

 arises from the stamen, it is called a parastemon.
