JAPANESE SPECIES OF BALANOPHORA. 197 
Bringing now my remarks on the Japanese Balanophora to a 
conclusion, I hope that my statements, however imperfect, may 
throw some light upon our present knowledge as to the occur- 
rence of Balanophoree in Eastern Asia; and that, at the same 
time, they will be of some slight assistance to those who may be 
in a position to make further observaiions on this interesting 
plant.

(Puare VI.) 
THE very interesting little terrestrial Orchid described in this 
paper was kindly communicated to me by Prof. Henriques, of 
the Botanic Gardens, Coimbra. It was obtained, with many 
other interesting plants, from the island of St. Thomas, West 
Africa, by the Portuguese Expedition in 1885. 
Prof. Henriques was anxious for me to publish an account of 
the Orchidez and Cyperaces of the expedition in the ‘ Boletin 
da Sociedade Broteriana,’ in which publication have already 
appeared the descriptions of the remainder of the botanical col- 
lection ; but on my urging the great interest of this plant, he 
consented to allow me to offer the publication of an account of 
it to the Linnean Society, in whose Journal it would be figured, 
and be more generally accessible to the scientific world.
