A very abundant grass in meadows at middle elevations. In the Sacramento-White 
Mountain region this is known as ‘‘sleepy grass,’’ and is said to have a narcotic effect 
upon animals that eat it, especially horses. While neither of the writers has had an 
opportunity of personally corroborating this statement, it is vouched for by many 
reliable residents of the region. The narcotic effects of the plant, which are said to 
appear soon after it has been eaten, are indicated by drowsiness or sleep on the part 
of the affected animals, which continues often for 48 hours and sometimes results in 
death. Animals which have been reared in these mountains never eat sleepy grass, 
but those which are brought into the region will consume it because of its luxuriance 
and freshness, unless restrained. Strangely enough, the dried grass does not have a 
narcotic effect. The grass is abundant in other regions of the State, but nowhere 
besides in this one range is it reputed to have narcotic properties, Where it is not 
eaten by stock it grows vigorously and spreads rapidly, especially when other plants 
are killed by overstocking.
