Oreobolus (and Voladeria)

John and Robert,
     Thanks for the information.  Not only has Schoenoides been synonymized
into  Oreobolus, but I discovered that so has a genus called Voladeria
(which was apparently originally classified in Family Juncaceae).  Voladeria
carchiensis is from Ecuador.
     It sounds like Seberg's analysis showed a paraphyletic subgenus
Costularia giving rise to Oreobolus, which makes me wonder if genus
Costularia might be split in the future by strict cladists (I might even
advocate some such splitting myself, although not automatically just because
it's paraphyletic).     I will be particularly interested to see how
Costularia xyridiodes (spelling?) from New Caledonia fits into this, since
New Caledonia seems to have been a refuge for a lot of primitive
     QUESTION:   I was looking on the Cyperaceae page of Watson and
Dallwitz's site, and it makes reference to Bruhl, 1998, "Genera of
Cyperaceae", but the URL given contains no such document that I could find.
Anybody know if Bruhl's work is still available anywhere online?
       ------  Thanks,  Ken Kinman
