ORDER SPHAGNALES 



FAMILY SPHAGNACE^ 



Sphagnum (Dill.) L. 



1. Cortical cells of stem and branches without spiral fibrils; 



branch leaves mostly truncate and toothed or fringed at 



the apex 3 



Cortical cells of stem and branches with spiral fibrils and 

 pores; branch leaves densely imbricated, cucullate at the 

 apex, not truncate, entire (Cymbifolia, p. 80) 28 



2. Branches in fascicles of 3-6 3 



Branches in fascicles of 7-14; chlorophyll cells of branch 



leaves elliptical in cross section and enclosed toward 

 both surfaces of the leaf by the hyaline cells* (Polyclada, 

 p. 81) S. Wulfianum 



3. Chlorophyll cells mostly triangular to trapezoidal in cross 



section, either free at both surfaces of the leaf or 

 enclosed toward one leaf surface by the hyaline cells, 

 but always with the base free toward one of the two 

 leaf surfaces 4 



* What is said here regarding the form and position of the chlorophyll cells 

 refers always to median cross sections of leaves taken from the middle of one of 

 the spreading branches.
