16 Trillium cemuum. 



The generic term Trillium is of Linnsean origin, and its derivation 

 is left unexplained. It is supposed, however, and with very little 

 doubt, to refer to the triple number of all the parts of the plant. The 

 calix and petals each consisting of three leaves, the stigmas and the 

 cells of the fruit three in number, and even the leaves are three. 

 Circumstances of formation constant throughout the whole genus, 

 with the exception of the single style observed by Mr. Nuttall in the 

 species T. stylosum.
