Systematics and distribution

The order of Paracryphiales is within the Euasteriden II, the sister group of order Dipsacales. It owns only one family, the Paracryphiaceae, in which the former families Quintiniaceae and Sphenostemonaceae were incorporated.

The Paracryphiaceae family was erected in 1964 by Herbert Kenneth Airy Shaw in Kew Bulletin, 18, p 265. Type genus is Paracryphia Baker f.

The position of the family of Paracryphiaceae has long been controversial and is valued even today different for different authors. The Paracryphiaceae was provided as a monotypic family, with the only kind Paracryphia alticola, in the order Theales. The mono- generic family Sphenostomonaceae, with the genus Sphenostemon, you turned to the Celastrales or Icacinales. The genus Quintinia was made a long time to woody Saxifragaceae or Hydrangeaceae. Last Winkworth et al. 2008, three genera in the family of Paracryphiaceae. Thus Quintiniaceae Doweld, P. van Royen Sphenostemonaceae today synonyms of Paracryphiaceae Airy Shaw. For the Paracryphiaceae family own Paracryphiales order is placed, which has close ties to the order of Dipsacales.

The family includes three genera Paracryphiaceae with about 36 species in the Philippines, New Guinea, New Zealand and New Caledonia.:
