DIFFERENT KINDS OF COROLLA.

founded*. The petal is defined by Ldnnaus " as a corollaceous 

 covering to the flower," meaning that it encloses and protects 

 in the manner of a corolla, or wreath. If the corolla be 



Monopetalous, of one petal ; it consists of two parts, viz. 

 The tube, or lower part, which is usually tube-shaped ; and the 

 limb, or upper part, which usually spreads wider. And the limb 

 again, according to its figure, is either campanulate (bell-shaped) , 

 that is, bellying out, and without a tube ;...infimdibuliform (fun- 

 nel-shaped), that is, of the figure of a cone, and standing on a 

 tube ;...hypocrater?form (salver-shaped), that is, plain or flat, and 

 standing on a tube ;...rotato -plane ( wheel- shaped, and fiat) , with" 

 out a tube;... or ringent (gaping), that is, irregular and personated 

 with two lips. But if the corolla be 



Polypjetalous, of many petals ; each petal consists of unguis, a 

 claw, which is the lower part fastened to the base ; and lamina, 

 a thin plate, which is the upper part, and usually spreading. A 

 polypetalous corolla is cruciform (cross-shaped) when it consists 

 of four petals that are equal and spreading ;...and papilionaceous 

 (butterfly -shaped) when it is irregular, consisting of four petals. 



* Petal (in the Greek ixrerahov) signifies leaves in general : but there being ano- 

 ther Greek word (tpuXXov) nearly of the same signification, the modern botanists have 

 borrowed this to express the leaves of the flower. The ancients seem to have had no 

 distinct term in use to express this part of the fructification. Thus Virgil, in describ- 

 ing his amellus, which is a species of aster, the flower of winch has a yellow middle, 

 and purple rays, calls it a golden flower, surrounded with purple leaves. 



Aureus ipse Flos, scd in foliis, qiue plurima cirairn 

 Funduntur, violce sublucet purpura nigra:. 



Georg. IV. 



This loose expression, which is chargeable rather on the language than the poet, 

 has misled all his translators ; as is rightly observed by Martin, in his note on this 

 passage. Thus Addison makes the real leaves of the plant purple : 



The flower itself is of a golden hue, 



The Leaves inclining to a darker blue. 



The Leaves shoot thick about the root, and grow 



Into a bush ; and shade the turf below. 



Addison.
