As for Chamaedorea I find it hard to keep alive, let alone under the constant stress of basking ligths and being climbed upon. Also doesant like to moist or to dry. It would be feaseble but the terrarium would have to be HUGE and it would have to stay in a distant but well iluminated corner (but not with a intense ligth!). As for more good plant choice Sheffheedera (hope Im spelling correctly) its one of the hardiest tall plants and Ficus pumilia is a hardy creeper. Fatsia is also hardy. But it would be good if you told us how big is the terrarium, how big its the basilisk,etc. If the lizard its a baby you should let him grow in a more higenic seting that can be cleaned easily and then later with lots of planing you can do your big and nice planted enclosure. Otherwise its just a waist of money. Also the rising of the dirt and leafs only works to a certain degree. What I here generaly do is take grafs of well stablished plants, let them grow and then transfer them to the terrariums, zero expenditure of money and 100% safe plants. Dont be on worry to finish your terrarium, you have plenty of time to do that, if your basilisk is young concentrate fully on its needs, use some plastic plants or some poted spineless ephifids after they have been put on quarentine (wait for the summer if need be) and your good to go. Oh and a very important peace of information to anyone that has basilisks, if you like your lizard helmet and crests (and Im shure you do) ALLWAYS cover the ligth sorces with metalic wires to prevent your lizard from burning himself!
Peace lilies and Dieffenbachia are DEADLY for lizards(and very toxic for humans by that matter)! Even if basilisks are not prone to eat vegetation its simply NOT WORTH IT. Bad things some way or another allways find a way to happen with thouse plants. Also I find Dieffenbachia very hard to keep in a terrarium, the leafs get burned and dry very easily, and the plant is prone to rot. It wont last long with a lizard with sharp claws!
