 upper leaves; calyx-tube narrowly obconic, densely tomentose, the lobes 

 gradually narrowed from the base, long, broad, acuminate, coarsely glan- 

 dular-serrate, tomentose below and glabrous above on the outer surface, 

 slightly villose on the inner surface, reflexed after anthesis; stamens 20; 

 anthers white; styles 5, surrounded at the base by a narrow ring of pale
