SECT. XIII. MESOPH**RIA (from jueiroe, mesos, the middle ; 

 and <70cuf>a, sphaira, a globe ; in reference to the heads of flow- 

 ers being semi-globose.) Benth. lab. p. 122. Heads rather 

 loose, few-flowered. Bracteas sometimes minute, or scarcely

 strict teeth ; the throat closed inside by hairs, or more or less 

 ciliated, with 5 fascicles of hairs, which are disposed between 

 the teeth. Tube of corolla inclosed, or a little exserted. 

 Herbs, rarely shrubs, for the most part pilose. Heads pedun- 

 culate : lower ones rarely all from the axils of the leaves : cau- 

 line ones conforming, solitary, or in fascicles : the superior ones 

 usually disposed into a loose panicle.
