Neomeris stipitata was collected at Singapore by Mr. H. N. 

 Ridley or one of his assistants and was described and figured with 

 much thoroughness and detail by Dr. Arthur H. Church of Jesus 

 College, Oxford, in the Annals of Botany in 1895, as quoted 

 above. Type material of the species is preserved in the herbarium 

 of the New York Botanical Garden and in the botanical depart- 

 ment of the museum of Oxford University. 



Ntomcris stipitata differs rather strikingly in several particulars 

 from the other members of the N. dunietosa group. The speci- 

 mens, which have been preserved in alcoholic media (ours trans- 

 ferred lately to 50 per cent, glycerine), are, at the present time, at 

 least, very much less calcified than those of any other known 

 species of the genus. Dr. Church writes us that he believes they 

 have lost fully 50 per cent, of their lime since he studied them in 

 1895, but even at that tirne {loc. cit. 582) he was impressed by 

 their "delicately calcified " condition as compared with the "densely 

 calcified " N. Kcllcri Cramer. Another peculiarity of A", stipitata 

 is found in its long sterile basal portion, constituting nearly half
