 being oppositipetalous. 



XI. EOSE MALLOW SEEIES {Fr., Ketmies). 



The Eose Mallows 1 (figs. 152-161) have flowers analogous to those 

 of the Mallows. Their calyx is gamosepalous with five valvate lobes ; 

 and the corolla, gamopetalous at the base and united with that of 

 the audroceum, is contorted in prsefloration. The stamens form a 

 tube with truncate or quinquedentate apex whence are detached an 

 indefinite number of slender 

 summits surmounted by a Hibiscus roseus. 



one-celled anther with longi- 

 tudinal 2 dehiscence. The 

 gynseceum is composed of an 

 ovary with free alterni- 

 petalous cells. In the inner 

 angle of each cell a placenta 

 is seen supporting either 

 an indefinite number of 



ovules arranged in two ver- 

 tical series, or only three or 

 four ovules. The fruit (fig. 

 159), around which the calyx 

 and epicalyx persist, is loculicidal, and at maturity allows reniform 

 seeds to escape, often more or less abundantly covered with hairs 

 and enclosing under their coats a thick embryo with large coty- 

 ledons more or less folded upon themselves. Between their folds is 

 often seen an inconsiderable mucous albumen. The Eose Mallows 

 are arborescent, frutescent or herbaceous plants, glabrous, tomentose or

- The pollen is formed of spherical or spiked 

 grains. " Long spines, few in number ; largo 

 pores, few in number. H. Trionum, H. syriacus." 

 (H. Mohl, in Ann. Sc. Nat., ser. 2, iii. 334.) 

 The anther generally presents the rudiment of a 

 partition at its base.
