22 Muhlenbergia, Volume 6 



Cespitosi 

 This section contains four species, which fall into two 

 groups of two species each. Two of them, L. alpimis and L. 

 pinetorum are low matted plants with decumbent or procum- 

 bent stems, the flowering ends raised only slightly above the 

 surface of the ground. The other two, L. sellulus and L. con- 

 fertus, while having the outer stems more or less decumbent, 

 are ascending or erect, sometimes almost or quite a foot high. 

 The peduncles, exclusive of the inflorescence, commonly extend 

 beyond the leaves in all these species.
