1897. Leaves rather rigid. 



Alpine, never tall ; root producing offshoots ; stems com-

 linear, streaked ; flowers crowded into an usually 

 solitary terminal capitular cyme ; bracts short, largely

 spreading terminal cymes ; sepals and petals very small, 

 brown; stamens three; fruit ovate-ellipsoid, three-celled,

J. planifolius. 

 Leaves narrow-linear. 



Never tall, simply tufted ; stems very slender ; leaves all 

 basal, much like those of grasses, but towards the summit 

 somewhat channelled ; flower-clusters in terminal spread-

 six ; fruit rather blunt, three-celled ; seeds without any 

 appendage. J. caespitititis.

1900. Flowers dispersed. 



Usually dwarf ; root producing conspicuous offshoots ; stems 

 somewhat compressed ; leaves rigid, channelled -linear ; 

 the floral leaves almost bractlike -shortened ; flowers, 

 almost spicate, in a dichotomous cyme or small panicle, 

 sometimes reduced to few ; sepals and petals slightly 

 pointed ; stamens six ; fruit ovate-ellipsoid, three-celled, 

 slightly exserted ; seeds without any appendage. Figure 



Flowers clustered. 



Usually dwarf ; root producing hardly any offshoots ; stems 

 much compressed ; leaves rigid, almost semicylindric ; 

 flower-clusters in a slightly branched leafy cyme ; sepals 

 and petals much pointed ; stamens six ; fruit ovate - 

 ellipsoid, three-celled, shorter than the sepals and petals ; 

 seeds without any appendage. J. honialocaulis.
