GLAUCIDIUM. 
This genus, established by Siebold and Zuccarini,* was based on 
anonens collected in Yezo, Japan. As these botanists had but 
ew specimens with fully opened flowers, they could not give a 
stifactory description of the genus, and they doubted whether the 
whorl of the perianth represented the calyx, the corolla beimg 
wanting, or whether the calyx was caducous, and did not remain on 
the fully opened flowers. The true nature of the perianth was 
precy. described by Bentham and Hookerf and by Baillon.{ 
There still remained an error Accs regard to the arrangement of 
on the placen enta. 
ow, there is only one species of this genus called G. palmatum,* . 
which is found in Yezo as well as on the mountains of Central 
Japan.
