|Sphagnum strictum occurs in dry woodlands, and forms whitish|
branch heads that are more compact than those of S. palustre.
|When dry, the branch heads become more feathery. Photo by Alan Franck. |

|The reddish sporangia of Sphagnum strictum appear|
in the spring.
|The leaf of Sphagnum strictum is composed mostly of large water-storage |
cells, which appear as empty. The cells are reinforced by fibrils wrapped
around each cell. What appear to be thick cell walls are actually the very
narrow photosynthetic cells.
