unhealthy jungle val

Hello all.  I recently obtained 20-30 clumps of jungle val (spp. ?) from 
a friend.  It is not in very good condition.  3-4" long and some is 
getting brown.  I want to revive it and dont know the best way to 
accomplish it.  I have the best plants I chose to keep at 76d F and my 
lights on 12-14h a day.  Any suggestions about requirements or anything 
would be appreciated.

                                             Thank You
