is defined by Linnaeus as a corollaceous covering 

 to the flower, meaning that it incloses and protects 

 it 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, accord- 

 ing to its figure, is either Campanulate, bell shaped, 

 that is, bellying-out, and without a tube ; ItiJ'undi- 

 buliform, funnel-shaped, that is, of the figure of a 

 cone, and standing on a tube; Hypocrateriform, 

 salver- shaped, that is, plain or flat, and standing on 

 a tube ; or Ringent, gaping, that is, irregular and 

 perforated with two lips. J3ut if the Corolla be 



POLYPETALOUS, of many Petals, each Petal con- 

 sists of Unguis., a claw, which is the lower part 

 fastened to the base ; and Lamina, a thin plate, 



rightly observed by Martyn, in- his note on this passage. May 

 and Addison make the real leaves of the plant purple: 



For from one root he spreads a wood of boughs, 

 Whose many LEAYES, although the flower be gold, 

 Black violets dimme purple color hold. MAY. 



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, 



Dryden applies the same color to the boughs : 

 For from one root the rising stem bestows 

 A wood of leaves, and vi'let purple BOUGHS. 

 The flower itself is glorious to behold, 

 And shines on altars like refulgent gold. DRYDEN. 



Dr Trapp applies the golden color to the stem, and the 

 purple to the leaves : 



For from one turf a mighty grove it bears ; 

 Its STEM of golden hue ; but in its LEAVES, 

 Which copious round it sprout, the purple teint 

 Of deep-dyed violets more glossy shines.
