band of fibers near the outside of the bract (interior to which are the bundles), 

 the outer epidermis is sclerified. Two to three layers of sclerenchyma are present 

 on the inner face of the bract ; thus, three distinctive bands of sclerenchyma are 

 present. Vascular bundles are mostly without associated fibers. In all char- 

 acters except the abaxial epidermis, bract structure in Anastraphia cowellii is 

 close to that of Hesperomannia.
