G, Afontaguel apjicars to be closely related to G. CminingJiami from Now 

 Zealand, from which however it differs in the remarkable size of ifs 

 rhizome and stipe which are £ inch in diameter; the largest rhizome of 

 Cunningliami I have seen (coll. Home, Bay of Ishinds, New Zealand, 

 Herb. Mus. Brit.) is only ^ inch in diameter. G. Montaguei also 



appears to be related to an unnamed Gl 

 Now Guinea (coll. Forbes 923 in Herb. Mus. Brit.), which has a similar 

 habit and mode of branching, and which has unusually large rhizome and 

 stipe (though smaller than those of G. Afontaguei). I dedicate this species 

 to the memory of my friend Paul Deuys Montague, my follow- worker in 

 New Caledonia.
