Germen, is its Proteétion orderd3 about fix ways whereof may be 
obferv'ds fè. by Leaves, Surfoyls, Interfoyls, stalks, Hoods and Mant- 
lings. Toadd to what we have above given, one or two Inftan 
Every Bud, befides its proper Leaves, is covered with divers Leafy 
Pannieles or Surfoyls 5 which, what the L are to one another, 
are that to themall: For not opening cx y, they admit 
not the Weather, Wet, Sun or Aer, to approac! xcept by 
degrees refpondent, and asthey are gradually inurd to bear them, 
Sometimes, befides Surfoy!s, there are any Interfoyls fet betwixt 
the Leaves, from the Circumference to the Center of the Bud; as in 
the Hafel. For the Fibres of thefe Leaves ftandi fo far from a 
plain furface 5 they would, ifnot thus fhelter'd, lic too much exposd 
and naked to the Severities of the Weather. W eof all the 
Protections above-named, are convenient, there t es of the 
Leaves by continuation in their firft forming ( together with fome Fi- 
bres of the Lignous Body ) are drawn out into fo many Mantles or 
Veils s asin Docks, Snikeweed, Exc. For the Leaves her being but 
few, yet each Leaf and its Stalk being both exceeding Jong; at the 
bottom whereof the next following Leaf fill fprings up; the form 
and pofture of all is füch, as fuperfedes all the other kinds of Protedti-
