IK/T YZ ODE N DR ON PUNCTULATUM, the subject of 
^ the present paper, is the only species of Gymnophyton , 
one of the two sub-genera founded by Sir J. D. Hooker in his 
monograph 1 on Myzodendron . Though the genus is so fully 
described and illustrated, the appearance of several papers 
bearing on parasitic Phanerogams (more especially those of 
Treub), since the date, 1840, of the publication of the Mono- 
graph, suggested to me that a re-examination of the plant in 
the light of recent investigations might prove of interest. I was 
able to carry out this idea through the kindness of Mr. J. R. 
Jackson, F.L.S., Curator of the Museums in the Royal Gar- 
dens, Kew. I am much indebted to him for excellent spirit- 
material taken from a fine fruiting specimen collected by the 
4 Challenger Expedition 5 in Patagonia.
