5. Luzula spicata var. nova, n. var. 



Differt a forma typica cum capsula segmentis perianthii sit semper 

 brevior. 



This variety, which appears to be strictly west American, is dis- 

 tinguished from the species by the mature capsule being always shorter 

 than the segments of the perianth and usually only one-half as long. 

 In the species, the mature capsule is exserted from the perianth. 



Wliile the variety here distinguished has, so far as known, no 

 other character unlike those of the species, its consistent exhibition 

 of the critical character throughout its definite range seems sufficient 

 warrant for its proposal. The specimen in which the distinction was 

 first recognized is Coville and Funston 1535 as represented in the 

 Gray Herbarium and this may be regarded as the type sheet.
