The above interesting discover}', in southern Japan, of a species of 

 Zeuxine, affords an opportunity ot making some remarks concerning the 

 geographical distribution of the genus. 



Prof. Pfitzer 1 ' pointed out, in 1889, that there were 20 species then 

 known to belong to this genus. Although he irave no enumeration of the 



included in other species, and the number thus reduced. In 1890, when 

 Sir J. D. Hooker-" revised the Indian species of this genus, by adding a 



terminal lobe< ti.tlu-lip. tlie eminent British b-tanist also estimated the niunh-r 

 of species of the genus at about 20. In ' Index Kewensis,' IV, p. 1250, 

 published in 189.5. only 11 are admitted there as being good species. 



Zeuxine has a very wide distribution in the tropical parts of Africa 

 and Asia ; in the latter continent, it is more abundantly found in India 

 than elsewhere. It also extends to the Malay Archipelago. In Africa 1 '), we 

 find 4 species, viz. Z. a/Hcana, Rchb. f., Z. elongate, Rolfe, Z. lepida, Trim., 

 and Z. tetraplera, Dur. et Scliinz ; in the Malay Peninsula'), 2 species, / 

 reniformis, Hook. f. and Z. affinis, Trim., of which the former being 

 endemic ; in the Malay Archipelago 5 ), some 5 species, including Z. dandestina, 

 Bl., Z. Java, Trim., Z. gracilis, Bl., Z purpureascens, BL, and Z. sulcata, 

 Lindl. ; in India 1 '), where species are the richest, we observe 10 species, viz. 

 Z. goodyeroides, Lindl., Z. nervosa, Trim., Z. affinis, Trim., Z. longifolw, 

 Hook, f., Z. abbreviate Hook, f., Z. moulmeinensis, Hook, f., Z. sulcata, 

 Lindl., Z. longilabris, Trim, Z. regia, Trim., and Z. flam, Trim., of 

 which the first 5 species ascend the high elevation of the Himalayas and the 

 Khasia Hills, while the last 4 species extend to Ceylon, including a species 

 endemic to the island ; in Burma, 1 species, Z. affinis, Trim. ; and in 

 Cambodia, also 1 species, Z. Qodefroyi, Rchb. f.
