The Classification Study Of Family Corallinaceae Lamouroux In Liaoning Coast

Corallinaceae Lamouroux belong to Rhodophyta,Florideae,Family Corallinaceae Lamouroux,it is worldwide algae.Because most of them have many variation on morphology,it is difficult to distinguish many genus and species,has not a acceptable classifier system.From September 2007 to September 2009,made morphology study of Corallinaceae Specimance in 16 collection locations of Liaoning Province.Identifies Corallinaceae 597 specimens,13 genus,21 species.Include 2 species of Amphiroa, A.zonata and A.echigoensis,1 specie of Bossiella,B.cretacea,4 specie s of Corallina,C.officinalis,C.pilulifera,C.sessilis,C. confusa,3 species of Lithothamnion,L.aculeiferum,L.intermedium,L.pacificum,2 species of Pneophllum,P.Fragile and P.zostericol,1 specie of Titanoderma,T.corallinae,1 specie of Pseudotithophyllum,P.samoense,1 specie of Hydrolithom,H.farinosa,1 specie of Fosliella, F.farinosa,1 specie of Mesophyllum,M.simulans,1 specie of Alatocladia,A.modesta,1 specie of Heteroderma,H.zostericola.1 specie of Phymatolithon,P.lenormandii.Includes 2 new record to Liaoning Province,they are H.farinosa and M.simulans,3 new record to China,they are A.Modesta,A.Echigoensis and C.confusa.This study makes particular discussions on morphology,particularly procreate apparatus and intergenicula type,and make observation on species,distribution,habits and characteristics,seasonal change of Family Corallinaceae.It shows a dollop of locality in this area because of human activity,and seasonal change obvious.This study basically ascertains species composition and distribution of Family Corallinaceae in Liaoning Coast, ascertains taxonomic position of each genus and species,sets up classifier system of Family Corallinaceae in Liaoning coast.Also,provides reference to development,utilization and study of classifier system to Family Corallinaceae.
