Botanists of BlueSky...I'm like 99% sure that deciduousness never evolved in lycophytes but please let me know if I am wrong! It would be very cool if it did!

All plants lose leaves - the plant may be biologically immortal, but leaves are not, they are disposable. In some plants, though, leaves are lost and replaced gradually or sequentially, so we don’t really notice them. So yes, lycophytes are deciduous sequentially.

I am not botanist, but my very favorite platonic person is, and this is what she had to say

I originally read this as "deliciousness" and now I'm significantly less interested than I was 30 seconds ago.

On a quick poke around I see that Selaginella kraussiana is deciduous in colder climates and evergreen in warmer ones; I'm not sure if you consider that sufficient. :)
