Triuridaceae
Encyclopedia
Triuridaceae is a family of flowering plants. Such a family has been recognized by relatively few taxonomists.
The APG II system
, of 2003, does recognize such a family and places it in the order Pandanales
, in the clade monocots. This is a change from the APG system
, of 1998, which left the family unplaced as to order, but did place it in the clade monocots.
Most sources assume the family to consist of some half dozen genera, with Sciaphila
as the biggest genus. However, H. Maas-van de Kamer and T. Weustenfeld (1998) regarded the family to consist of the following nine genera :
The Kew "World Checklist of the Triuridaceae" was reviewed by H. Maas-van de Kamer and P. Maas-van de Kamer in 2005. In this list the genera Andruris and Hyalisma are synonymized into Sciaphila, but two new genera Kupea
and Kihansia are included. Both genera were described (and placed in Triuridaceae) in 2003. The revised list of genera is thus:

APG II system
The APG II system of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Group. It was a revision of the first APG system, published in 1998, and was superseded in 2009...
