Are the lycopodium really true ferns?

Are asparagus also true ferns? How about the members of the Lycopoda?

Are the lycopodium really true ferns?
A fern, or pteridophyte, is any one of a group of about 20,000 species of plants classified in the Division Pteridophyta, formerly known as Filicophyta. A fern is a vascular plant that differs from the more primitive lycophytes in having true leaves (megaphylls) and from the more advanced seed plants (gymnosperms and angiosperms) in lacking seeds. Like all vascular plants, it has a life cycle, often referred to as alternation of generations, characterized by a diploid sporophytic and a haploid gametophytic phase. Lycopodium is a genus of clubmosses, also known as ground pines, in the family Lycopodiaceae, a family of fern-allies (see Pteridophyta). They are flowerless, vascular, terrestrial or epiphytic plants, with widely-branched, erect, prostrate or creeping stems, with small, simple, needle-like or scale-like leaves that cover the stem and branches thickly. The fertile leaves are arranged in cone-like strobilli. Specialized leaves (sporophylls) bear reniform spore-cases (sporangia) in the axils, which contain spores of one kind only.



Asparagus is an angiosperms .So, It is not a true Fern.
Reply:I don't think any of these are true ferns. "Asparagus fern" isn't even close. It just resembles ferns to some extent.
Reply:absolutly yes, they are the ORIGINAL plant life on earth
