DESCRIPTIONS OF THE SHRUBS 



Fia. 131. — Purple Cytisus. 



• Genista. The true Genistas (flo- 

 rists' Genistas are usually Cytisus) 

 iiave pea-like yellow flowers and few 

 alternate simple entire-edged leaves. 

 Tlie calyx-lobes are longer and more 

 slender in true Genistas and tlie pods 

 are shorter. 



While neither genus is fully hardy 

 North, and while both contain a num- 

 ber of species which might be worth 

 cultivating, very few are in cultiva- 

 tion. 



The only one needing description 

 is probably Woad-waxen or Dyer's 

 Greenweed (129) — Genista tinctbria 

 an erect shrub to 3 feet with yellow 

 flowers along the tips of the branches in 

 early summer.
