Globe-Flower. 



Calyx petaloid, regular, imbricated in aestivation : sepals 

 5 to 20, orbicular or obovate, remaining incurved, so as to 

 give a globular form to the flower (whence the popular 

 name for T. Europasus), or spreading, deciduous. Petals 

 5 to 20, hypogynous, small, little exceeding or shorter than 

 the stamens, which they somewhat resemble, ligulate or 

 linear-spatulate, thickish, gland-like, slightly unguiculate, 

 somewhat excavated or tubular on the inner side next the 

 base, deciduous. Stamens indefinite, hypogynous : fila- 

 ments filiform : anthers short, innate, the cells opening lat- 

 erally, or slightly introrse. Pistils 9 to 30, sessile on the 

 globular summit of the receptacle (gynophore) : ovary one- 

 celled, many-ovuled, tapering into a short style ; the stigma 

 unilateral at its summit. Ovules numerous, anatropous, 

 horizontal in two rows occupying the whole length of the 

 ventral suture ; their raphes collateral (face to face). 



Fruit follicular. Follicles 9 to 30, capitate, closely 

 sessile, erect or barely spreading, coriaceous, nearly cylindra- 

 ceous, transversely veiny from the dorsal rib, from which is 

 exserted the subulate short style, dehiscent through the ven- 

 tral suture from the apex downward. Seeds horizontal, in 

 two rows, 5 to 10 in each, ovoid or angled : the smooth and
