rv INTEODUCTION. 



Hainan, Lia-Kiu, and the Bonin Islands, as I consider them to 

 be regions closely relafced botanically to Formosa. 



My readors will notice that I have substituted the word 

 " Volume " for " Fascicle " as used in the preeediug portions of the 

 Icones Plantarum Formosanarum, nec non et Contributiones ad 

 Floram Formosanam. As each of theso portions contains more 

 than two hundred pages and thirty platos, the word " Yohime " 

 seems more appropriate than " Fascicle." 



In conclusion, I avail myself of this opporfcunity to tender 

 my hearfcy thanks to the officials of tlie government of Formosa, 

 to whom I ani mucli indebted for lielp in the collection tif 

 raaterials and in the pubHcation of this work.
