Abstract The introduction and culture of 30 ferns are researched. They are Isoetes sinensis ,Angiopteris fokiensis, Osmunda vachellii , Pteris voallichiana , Asplenium ensi forme , Athyrium caudi forme , Matteuccia orientalis, Dryopteris uniformis,Polystichum dielsii, etc. The results showed： （a） the introduced ornamental ferns have very high survival rate; （b）they can be supervise easily; （c）most of them are evergreen and graceful, and have higher ornamental value. They can overwinter safely in Huaihua city so long as the temperature below zero in winter which never last 1 week or more. Hence, these ferns are worth exploiting in subtropical zone; （d）nine ferns（Osmunda vachellii ,Alsophila metteniana , Ath yrium otophorum , Ath yrium iseanum , Ath yrium caudi f orrne , Ctenitopsis sinii , Dryopteris uniformis, Polystichum dielsii, Cyrtomium balansae） yield sporangium as soon as they expand leaf; （e） the sporangium of most of the ferns becomes ripe after 30-40 days＇development; （f）the periods of foliage leaf germination and expansion will be postponed half a month also if they are introduced and cultivated after germinating. But the appearance time and ripeness time of sorus remains changeless; （g）the sorusperiods of different species are different. Nevertheless, they are relative stable in the same species and therefore can be used as one of the evidences of differentiation. We propose that the ferns sorus periods should be put in the revisal Flora Reipublicae Popularis Sinicae and local floras.
