Lycopodium plants produce homosporous spores. This means that they produce only one type of spore, which is capable of developing into both male and female gametophytes.

Here's a breakdown:

* Homosporous: Producing only one type of spore.

* Heterosporous: Producing two types of spores, a smaller microspore (male) and a larger megaspore (female).

Lycopodium, along with other members of the Lycophyta group, are homosporous. This is in contrast to seed plants, which are heterosporous.
