with nutriment from the cotyledons, and alfo the placental artery, 

 which was fpread on the exterior membrane of the cotyledons for the 

 purpofe of oxygenation. Thefe veflels now either coalefce and decay

II. I. The feeds of plants are thus a fexual or amatorial progeny, 

 produced principally by the male part of the flower, and received 

 into a proper nidus, and fupplied with nutriment by the female part 

 of it, and which can thus claim both a father and a mother, fiut the 



1 



buds of vegetables are a linear pogeny, produced and nouri(hed by a 

 father alone, to whom they adhere, not falling off like the feeds, as 

 is farther treated of in Zoonomia, Vol. I. Se£t. XXXIX. II. 2. and in

of this work. For in this moft fimple kind of 



getable reprodu£lion, by the buds of 



and by the bulbs of fomc 



plan 



and by the wires of others, which are their viviparous p 



geny, the caudex of the leaf is the parent of the bud or bulb, or wire, 



which rifes in its bofom, according to the obfervation of Linneus. 



This linear or paternal progeny of vegetables in buds or bulbs, or 



res, is attended with a very curious circumftance, which is that 



they exadly refemble their parents, when they are arrived at their 



w 



maturity, as

2. As the embryons in the buds are the viviparous offspring of 



c^etables, it becomes neceffary, as they h

vefTels to fupply them with nourifhment, till they acquire roots with 



another fet of abforbent veffels to imbibe mdflure from the earth, and 



leaves to ad like lungs for the purpofe of oxygenating their blood.
