The bud of thefe herbs, which 



fes in the bofom of a leaf 



d 



commonly called annuals 

 adheres to its parent, requires 



1 roots 



no female apparatus to nourifli- it, but gradually ftrikes dovv 

 from its caudex into the ground, v^^hich caudex forms a part of the 

 bark of the increafing plant. This occurs in thofe herbaceous vege- 

 tables, which have juft rifen from feeds j the buds of which are pro- 

 perly individual annual plants, which grow to maturity adh

This circumflance alfo happens, I fuppofe, to the evergreen fhrubs 

 and trees of this climate, as to heath, rue, box, pine, laurel ; for in 

 thefe veo-etables, as the leaf does not die in the autumn, it continues 

 to oxygenate the blood, and to fupply nourishment to the bud in its^ 

 bofom during the fine days of winter, and in the ipring, and furvives- 

 till near midfummer ; that is, till the new bud has expanded a leaf of 

 its own. Whence I fuppofe thefe evergreens lay up in fummer no- 

 ftore of nutriment in their roots or alburnum for the fuftenance of 

 their enfuing vernal buds ; and have thence probably no bleeding fea- 

 fbn like deciduous trees.. 



But the embryon in a bud of a deciduous plant leaves in the fpring, 

 of the year its winter cradle, or hybernaculum, like 'the embryon in 

 a feed, or a chick in the egg ; and like thefe the young plants of 



different vegetables have previoufly arrived at different Hates of matu-
