with a head of four verticillate Jloivers, and a fifth terminal one. " Sta- 

 mens united in pairs, or they may be considered as four to five forked

 and all springing from a fleshy ring that surrounds the upper part of 

 the (jermen. The flowers have an evident musky smell in the eve- 

 ning, or early in the morning, while the dew is on them." Hooker.
