The plant was formerly referred to 0. puinila by Prof. J. MATSUMUBA, bu, 

 differs from that species by the much shorter corolla. Jt comes quite near 

 0. Tashiroi MAXIM, from which this differs by only the leaves which are 

 very pale on the under side. The leaves of 0. TasTdroi are reddish purple 

 on the under surface in a dried specimen.
