(182) TENTAMEN FLOK^ LUTCHUENSIS. 449 



young, but soon become glabrous, densely tomentose beneath, 

 with a few short prickles on the midrib, apex acute or obtuse ; 

 petiole 2-3 cm, long, also clothed with brownish wool. Inflores- 

 cense terminal on new branches, reflexed or arcuate, shorter 

 than the leaves. Flowers .5-7, crowded together in short bran- 

 ches, each 2 cm. in diam.; peduncles about 2 cm. long, highly 

 tomentose. Bracts 1 cm. or more long, h-l cm. wide, deeply 

 divided into narrow lobes. Calyx-lobes subtruncate 0-7 mm. 

 long, densely tomentose. Petals much larger than the calyx- 

 lobes. Filaments glabrous. Carpels numerous.

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 

 1-1-2 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 different in being thickly clothed with 

 brownish wool on the under side.
