22. H, rJormani^ F. Muell. Fragm, ili. 4. An undershrub, with ap- 

 parently simple erect stems of about 1 ft., densely velvety-tomentose. Leaves 

 jietiolate, from ovate to lanceolate, acute or obtuse, 2 to 3 in. long, obscurely 

 sinuate-toothed, tomentose on both sides,. especially underneath. Peduncles 

 1-^ to 2 in. long. Involucre of 5 broadly-ovate or rhomboidal leafy brac- 

 teoles, nearly as long as the calyx, distinct or scarcely united at the base- 

 Calyx tomentose, about \ in. long, deeply divided into ovate-lanceolate 3- 

 nerved lobes. Petals about twice as long or rather more, glabrous.
