Distributional notes
The record of Udotea orientalis from Fiji (Littler & Littler, 2003: 260) appears to be in error as no material of that species has been seen by us in current collections from that locality. Their photograph shows a plant with a thin blade where the parallel siphons are clearly visible, hinting at a monostromatic nature which is in contrast to the thicker, felty and woven plurisiphonous blade of 'true' R. orientalis. In our experience (Payri & N'Yeurt, unpubl.), Udotea glaucescens can show both a divided and undivided stipe with one to several monostromatic blades, and both Udotea records from Fiji in Littler & Littler (2003) would conform to U. glaucescens. - (4 Sep 2007) -

General environment
This is a marine species.

Type information
