difference in the disk scales. In the type one of the two opposite scales is oblong 

 and bifid, the other broadly oblong to nearly quadrate, bifid at the apex and with 

 a more or less distinct tooth on each side below the middle; in the Formosan plant 

 one of the scales is divided to the base into two linearnDblong lobes, while in the 

 other the linear-oblong lobes are connate below the middle. Maximowicz, who 

 apparently did not know Gray's original description based on specimens collected 

 in the Liukiu Islands by C Wright in 1856, as he quotes " A. Gray in sched.," 

 bases his description partly on other material. The leaves in the type specimen 

 are 2.5-3.5 cm, long and 1.3-1.8 cm. broad, with 8-10 pairs of veins, and the 

 petioles are 1-2 mm. long, while the measurements Maximowicz gives are 

 considerably larger. Hemsley's W. obovata^ also from the Liukiu Islands, differs 

 according to the description in the glabrous flowers and glabrous ovaries, other- 

 wise it seems very similar.
