Idea 27. And first, their Colours; where, with respect to several Plants and 

 Parts, they are more Changeable; as Red, in Flowers; or Constant, as Green in 

 Leaves, Which, with respect to several Ages of one Part, are more fading, as Green 

 in Fruits; or durable, as Yellow in Flowers. In what Parts more Single, as always 

 in the Seed; or more Compounded, as in the Flower; and in what Plants more 

 especially, as in Fancy. Which proper to Plants that have such a !Fas<e or Smell, 

 as both, in White Flowers, are usually less strong. To Plants that flower in such 

 a Season, as a Yellow Flower, I think, chiefly, to Spring Plants. And to Plants 

 that are natural to such a Soil or Seat, as to Water-plants, more usually, a white 

 Flower. What, amongst all Colours, more Common to Plants, as Green; or more 

 Rare, as Black. And what all these Varieties of Colours are upon Cultivation, but 

 chiefly, in their natural Soil. To observe also with their superficial Colours, those 

 within: so the Hoots of Docks, are Yellow; of Bistort, Red; of .4ve%s, Purple; but 

 of most, White. Where the Inward, and Superficial Colours agree; as in Leaves; 

 or vary, as in the other Parts frequently. And in what manner they are Situated ; 

 some universally spreading, others running only along with the Vessels, as in the 

 Leaves of Red Dock, and the Flowers of Wood-Sorrel.
