Allied to the above, but differs by the following charac- 

 ters : 



Branches erect (?), more slender, thinly tomentose and less 

 prickly. Leaves ovate-oblong or ovate, 6-10 cm. long, 3-6 2 cm. 

 wide, glabrous on both sides, or sparsely clothed with brownish 

 wool beneath, apex acuminate or sometimes obtuse ; petiole 

 1-1 i cm. long. Inflorescence erect, exceeding the leaves. 

 Flowers about 5-6, each on a long peduncle, which is 

 2-3 cm. long, densely clothed with brownish wooL Bract 

 none. 



There are some specimens from Formosa, collected by Makino, 

 very closely related to the Luchuan plant, especially by the 

 form of leaves, but diflerent in being thickly clothed with 

 brownish wool on the under side.
