Sleepy grass (stipa robusta) is a coarse perennial range grass which is native to Colorado, New Mexico, Texas and Arizona. It has an infamous reputation in this section of the country because of its effect on livestock, particularly horses ... 

The active principle in sleepy grass has been identified at last, in the December, 1992 issue of Discover magazine a recent study is mentioned in which Stipa robusta has been found to contain D-ly-sergic acid amide. Interestingly, the alkaloid is actually produced by Acremonium> a symbiotic fungu living within the plant s tissues. So closely have the two... 

Stipa robusta seeds are tiny, black, long and thin - kind of a smaller version of wild rice seed. I recently planted eight seeds, which all came up in my starter trays within a week.

There have been recent reports of a wholly new source of lysergic acid amides. The so called Sleepy Grass (Stipa robusta) of the desert areas of the American West is reported to have an alkaloid content approaching that of ergot, and should be a good source of raw material to feed into acid production. See Discover magazine, Dec. 92. 

Infected individuals of several grass species are more resistant to a number of insect herbivores (Clay, 1988). Further, seeds of infected species are more resistant to herbivore attack (Cheplick and Clay, 1988). Lysergic acid amide (10), isolysergic acid amide, 8-hydroxylysergic acid (15), ergonovine, chanoclavine I (7), and A(-formylloline all were isolated from Stipa robusta infected with an Acremonium endophyte (Petroski et al., 1992 Powell and Petroski, 1992).
