ThePterocladiaceaeis a smallfamilyofred algaecontaining 2 genera ofagarophytes.[1]
They are found growing on the coast of Portugal, South Africa, India, Japan, Mexico, Chile and New Zealand.[2]
From theGelidialesorder,GelidiumJ.V. LamourouxandPterocladiaJ. Agardh,are two of the most widespread genera (which have been often confused for each other) of the Gelidiaceae family. They are separated only by basic features ofcystocarps(fruiting structures). The genusPterocladiellaSantelices et Hommersandwas later established to segregate fromPterocladiathose species with distinct carposporophyte developmental characters (Santelices and Hommersand 1997).[3]
Molecular analyses of taxa within the Gelidiales have identified four major lineages equivalent toGelidiella,PterocladiaandPterocladiellaas sister taxa, and a fourth large clade including species ofAcanthopeltis,Gelidium,Ptilophora,PorphyroglossumandCapreolia(Freshwater et al. 1995, Bailey and Freshwater 1997, Freshwater and Bailey 1998, Shimada et al. 1999).[3]
So the family ofPterocladiaceaewas derived in 2006 to hold the genera ofPterocladiaandPterocladiella.[3]

Taxonomy
[edit]The family name ofPterocladiaceaeis derived from the genusPterocladia,which is derived from the Greek wordspteronmeaning wing andcladosmeaning branch.[4]
Genera

- PterocladiellaB.Santelices & M.H.Hommersand, 1997(14)
Figures in brackets are approx. how many species per genus.[5]
Uses
[edit]Agarcan be derived from many types of red seaweeds, including those from families such asGelidiaceae,Gracilariaceae,GelidiellaceaeandPterocladiaceae(includingPterocladiella,[6]). It is apolysaccharidelocated in the inner part of the red algal cell wall. It is used in food material, medicines, cosmetics, therapeutic and biotechnology industries.[2][7]
