SOLVED. Science fiction series read in the early 80's. The only detail I remember is they encountered walking plants with sharp edges that would try to slash their face plates to get at their oxygen. [s]

It had 3 astronauts, a girl and 2 guys. Told from the girl's POV, I think. Had at least 2 books with these characters. The only detail I remember is they encountered walking plants with sharp edges that would try to slash their face plates to get at their oxygen. They dealt with a few at the beginning, then a horde later. One of the books in the series had a title something like "Where the Sun Never Rises".

The Galaxy 5 series by Leo P. Kelley? One of the books is Where No Sun Shines.
