This pack contains 35 .3ds files, which are 7 different alien plants, with 5 variations of each plant.

While not greatly descriptive, the plants are:

Bluegrass

Bluey

Firey

Marsh

Pinwheel

Purp

Whisp

 These models will probably require a bit of work to get in game as they are quite polygon heavy (~20,000polys each) and texture light.  To look and perform their best you will probably want to optomise them for your engine and use some new textures for them.
