NOTES ON THE ORCHID FLORA OF 



NEW GUINEA I. 



Walter Kittredge 



The following nomenclatural and taxonomic notes are pre- 

 sented as a precursor to a checklist of the orchids of New Guinea 

 currently under preparation. In this first part new generic records 

 as well as new combinations are included. Subsequent parts will 

 include typifications of various sectional names and descriptions 

 of new species. The arrangement of genera follows the system 

 presented by Schlechter in his "Die Orchidaceen von Deutsch- 

 Neu-Guinea", published in Fedde, Repertorium specierum nova- 

 rum regni vegetabilis Beihefte 1: 1-1042, 1911-1914. 



Peristylus Turneri (Rogers) Kittredge, comb, now 

 Basionym: Habenaria Turneri Rogers, Roy. Soc. S. Austr. 49: 

 254, 1925. 



Anoectochilus papuanus (Schltr.) Kittredge, comb, now 

 Basionym: Eucosia papuana Schltr., Fedde, Rep. Beih. 1:76, 

 1911. 



This is one of several peloric species which Schlechter failed to 

 place correctly. While the peloric lip, lacking a spur, somewhat 

 obscures its generic affinities, this species can definitely be 

 assigned to Anoectochilus. The habit of closely-spaced, ovate, 

 short-petiolate leaves and few-flowered inflorescence of large 

 flowers is entirely that of Anoectochilus, as is the column with its 

 large bifid rostellum placed well behind the two lateral stigmas, 

 and the long Y-shaped pollinarium with a small visicidium. Pre- 

 vious records of Anoectochilus from New Guinea have been 

 identified as species of Macodes.
