this the insertion of the perianth is somewhat perigynous. The calyx 
is gamosepalous with the edges cut straight, or more often divided into 
from three to five obtuse unequal lobes. The corolla is malvaceous 
with five very deep divisions, contorted in præfloration. Its lower 
part is in one single piece, and united thus far with the base of the 
androceum. This is formed of an indefinite number of stamens, with 
filaments free in the greater portion of their length, but more or less

one-celled, more or less fornicate, with lateral! dehiscence. The 
gyneceum is formed of an ovary with slightly inferior base, sur- 
mounted by a style whose stigmatiferous apex is divided into five 
lobes or very short branches. They correspond to the ovary cells 
superposed to the petals and containing in their imner angle a 
placenta bearing anatropous ovules arranged in several series. The 
fruit is a capsule, generally woody and loculicidal, separating into five 
valves to allow numerous seeds to escape plunged into a thick’ 
wool, and enclosing under their coats a thick fleshy embryo
