Sleepy catchfly ( Silene antirrhina) .—This is a smooth, annual herb. 
It is called sleepy because its flowers are usually closed while the 
sun is shining, and it is called catchfly because one or more portions 
of the upper part of the stem are covered with a sticky substance 
which prevents insects from creeping up the stem. It grows 1 or 2 
feet high and has lance-shaped or linear leaves and pink flowers borne 
on long stalks in a panicle. 
Silene multicaulis is usually less than a foot high and quite hairy. 
As a rule its pale red flowers are produced in short, three-flowered 
clusters. 
Moss campion ( Silene acaulis) is a dwarf, mosslike plant which is 
found at high elevations. It has crowded, linear leaves and the 
purplish flowers are solitary and terminal on very short stalks. 
Silene or eg ana has also been reported in the park. 
Lychnis drummondii is a somewhat hairy and sticky plant, 
1 or 2 feet high, with lance-shaped or linear leaves, and a few flowers 
that vary from whitish to purplish red. 
Lychnis vespertina has also been reported in the park. 
Starwort (S tellaria) .—-The starworts are low plants with small, 
starlike, white flowers. There are usually 5 two-cleft petals, 10 
stamens and 3 styles. The following species have been identified in 
the park: Stellaria alpestris , S. borealis , S. crassifolia , S. edmardsii , 
S. longifolia , S. long\ipes , S. obtusa , and S. umbellata . 
Mouse-ear ( Cerastium arvense) .—This is a low, hairy plant with 
white flowers and can be distinguished from the starworts by the 
fact that there are five styles in the flowers.
