Sj)ec. Char., S^c. Leaves dotted from glands beneath, 3 — 5-lobed. Racemes 

 loose. Bracteas minute, subulate or obtuse, much shorter than the pe-

 whitish, or yellowish green. Calyx often of a rich brownish red colour 



or pink. Stamens sometimes more than 5, in which case there are fewer 

 petals ; so that when there are 10 stamens there are no petals. This 

 change of petals into stamens is just the reverse of the process by which 

 single flowers become double; and it is the only fact of the kind which has
