Innovations occur in the form of small slightly elongated 
turions which may lengthen into closely scaly rhizomes and 
develop into leafy shoots in the first season. 
Simple, taller, thicker-leaved plants of the general habit 
of this variety were collected at Glacier Bay, Alaska, by 
G. F. Wright in 1886 (Hb. Gray.), but I hesitate to place 
them definitely. They also suggest in some respects 
forms of EZ. Hornemanni. Some specimens resembling 
this variety also occur in the herbarium of the Depart- 
ment of Agriculture among Watson’s plants ftom Utah and 
Nevada. 
++ £ Producing subterranean scaly branches (sobols), which ulti- 
mately turn upward and usually develop at once into leafy shoots. 
++ Glabrous (or occasionally very slightly glandular above), and glau- 
cous: stems terete, slender, rather tall except in the variety, usually 
somewhat cespitose: leaves mostly simple and opposite, subsessile, with 
faint lateral veins: flowers erect or suberect: seeds obovoid, scarcely 
beaked, coarsely papillate. 
31. E. @uaBEeRRiMUM, Barbey.— About a foot high, 
simple or nearly so; leaves erect or ascending, often re- 
‘mote, as much as 50 mm. long, all but the lowest lanceo- 
late, rather obtuse, entire to slightly repand, mostly 
cuneately narrowed to the sometimes subpetioled base; 
petals purple to nearly white, 4 to 8 mm. long ; capsules 75 
mm., linear-falcate, usually conspicuously stalked; seeds 
.3 to .5x1 mm., very rough with blunt papille, abruptly 
rounded to the short insertion of the barely dingy coma. —
