BURMANNIACE^. 



HAB. Loo-Choo : Tanekoshima, leg. K. TERUYA, Aug. 1910. 



The plant was formerly referred to B. nepalensis which is but obscurely 

 described in HOOK. f. Fl. Brit. Ind. V. p. 666, and equally faintly illustrated 

 by MIERS in Trans. Linn. Soc. XVIII. p. 537, t. XXXVIII. f.-l, under the 

 name of Gonyanthes nepalensis MIERS. Though I have not seen the type, I 

 strongly doubt its being the same as our plant. As far as the illustration 

 of MIERS is concerned, our plant differs from that species by the much obtuse 

 perianth-lobes and by the quite obtuse or rather blunted scales on the stems. 

 Species of Burmannia on the whole seem to be very local, each region having 

 the peculiar species of its own. Thus, Burmannia japonica which was formerly 

 regarded as the same as the Indian B. Championi THWAITES is proved to be 

 different from the latter. Our Loo-Choo plant is very likely to be also different 

 from the Indian B. nepalensis. The description above given is drawn from a 

 specimen with nature capsules crowned with a persistent perianth.
