ROSACEAE (ROSE FAMILY) 



205 



Stems erect, two to four feet tall, woody, so hard 

 and brittle as to nick scythe blades and break mowing 

 knives, the bark red and clothed in rusty wool 

 which readily rubs off. Leaves long ovate, unequally 

 toothed, obtuse at apex, the base rounded or 

 abruptly narrowed to a short petiole, smooth and 

 green above but covered underneath with tawny or 

 whitish wool. Flowers in dense terminal racemes, 

 spire-like, deep rose-pink, sometimes a reddish purple, 

 occasionally white. The roundish, pointed follicles 

 are also woolly, filled with minute, brown seeds.
