 er than tiiat of Hananelis. Tt has from five to seven 

 very sinall calyx teeth. The development of the stam- 

 ens is as described by Paillon (3). They arise first 

 as five sinp;le rudiments, whi^'h are followed by other 

 rudiinents on either side, so t!iat there are finally 

 five p;r'Oups of five or six stamens. Those of each

 They pass the winter in the pollen mother-cell sta^^e. 

 At the time o T flo-^ering the ovules are not yet ready 

 for fertilization, so that the pollen must have a res'' 

 in/3 period of nearly a week. The anthers are quadri- 

 locular and open by two valves instead o ■^ one, very 

 much as is cocaaon in most anffiosperm stamens which 

 open by slits. The structure of the seed and fruit 

 is like that of Ifamamelie, except that the seed is
