ENGELMANN—NORTH AM. SPECIES OF JUNCUS. 483 
23 diameters ; about 8 ribs are visible on the side; the net- 
work of the surface and ag cross-lines of the areew are very 
delicate but + lg distine 
n 4 feet Tigh, with a stem 3 lines wide, and 
leaves 3 or 4 - - sometimes even 6 lines eee panicle 4-8 
the last, with leaves 2-3 lines wide, is distinguished by its 
showy, glistening, ee ragga about 4 
inches in length; sepals almost nerveless; capsules larger 
an in the other forms and pice than the sepals, thas 
an tery the following species. Var. y, the mountain 
of the latter; flowers 12 lines or more in length; seeds 0.25- 
and abrupt points. a with its very flat and somewhat 
curved, sword-shape Sona _ usually, few joe dark-eol- 
ored heads of triandrous flow rs, looks quite peculiar, but 
flower, fruit and seed are the ‘ie as in the other form 
find plants of the same habit and with the same kind of leaves 
and heads among the] different forms of J. Mertensianus and 
of J. pheocephalus, but the fruit and flowers will always dis- 
Sueee them. co seeds in this variety are intermediate 
betw en those of the last and those of the other forms.— 
oe (Linn, 3, 373) describes J. ensifolius with an obovate 
obtuse a ; I do not find it so, bat suppose he had a spe- 
cimen of J. Mertensianus in view, for which this shape of the 
capsule is an characteristic.
