Racomitrium Moss (Racomitrium affine)
Description
This species sometimes has bistratose margins in one cell row on some leaves and is reported to have forms with no or very short hairpoints. The few plants I have identified all have long hair points. This species sometimes has bistratose margins in one cell row on some leaves. The occasional sections with a bistratose margin are scarce but they do occur regularly (Bednarek-Ochyra 1995). This is important to remember if one encounters such a section: it doesn't rule out R. affine. This situation emphasizes the importance of making preparations with many sections from more than one shoot.
