Hub. Prov. Tosa : Kochi (T.Makinol Nov. 1895 ; A'. Okamural Nov. 

 1905); Prov. Sastuma: Shiroyama iu Kagoshima (T. Uchiyamal herb. 8c.

This is uncommon in Japan, and it is unquestionably very distinguished 

 from Dendrobrum moniliforme Sw., a common species in this country, by 

 its inflorescence, perianth, labellum, colour of the flower and flowering time. 

 And the leaves are broader and the stem is longer than in the latter. 

 According to Mr. 8. (jkubo, this species was also found by him on Mt. 

 Hachijo-Fuji in Hachijo Isl., 1887.
