BRACTEA, a thin leaf or plate of any me= 

 tal ; folium Jlorale, ranged by Linnaeus among 

 the Fulcra of plants. Thefc floral leaves dif- 

 fer in fliape and colour from the other folia of 

 the plant, are generally fituated on the pedun • 

 cuius, and often fo near the corolla as to be eafi- 

 Iv miftaken for the calyx, than which however 

 the Bra^ea are generally more permanent. Ex- 

 amples of floral leaves are feen in the Tiiia, Fu- 

 maria bulbofa, Lavendula, Horminum. Bra£le<s 

 are either colorata, caduccs, deciducs, perfiflentes ; 

 una, dua, plures ; coma ; foliorum cetera addenda.

 ral leaf] having hra£lecE growing on it. 



BULBIFERUS Caulh [a Bulbus, a round 

 root] bearing bulbs : thefe are generally on the 

 defcending caudex ; but when on the caudex a- 

 fcendens, if they touch the ground, they imme- 

 diately put ionh. fibrilla, and become real roots, 

 as in the Ranunculus fie aria. 



BULBOSA iJfli/A' [a Bulbus, afpeclesofo- 

 nlon] enlarging in a globular form at the bot- 

 tom of the afcending caudex, and fhooting
