This l ist was compiled on the mrn ing of July 3 , 1986, by t h e author on a f i e l d t r i p with Sam Antonio and K i m Foster. We-concentrated on the a rea around the small lake. A few species w e r e added from visual sightings along the road, and from observations made a few weeks e a r l i e r on a v i s i t t o the area by the author and Dick Antonio.

Specimens were collected fo r the Open Space herbarium, and cer ta in ones were taken i n duplicate for t h e University of Colorado Herbarium.

The following are especially noteworthy records:

Carex hystericina Muehl., known previously f r m a few col lect ions from t he general v i c in i ty of north Boulder. This species forms a d e f i n i t e zone i n shallow water of the pond margin.

Calamagrostis s t r i c t a (Timm) Koel, ( inexpansa) . This manuscript is on Disk 65 and can be updated.
