W i l l i a m A. Weber

This list w a s -piled on t h e morning 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 t h e a r ea around t h e small l a k e , A few s-wcj es w e r e added from vi SI=?_ inht.i nTc along the road, and f r an observations made a few weeks e a r l i e r on a v i s i t t o t h e a rea by t he author and Dick Antonio.

Specimens w e r e collected f o r the Open Space herbarium, and ce r t a in ones w e r e taken i n dupl icate fo r t h e University of Colorado Herbarium.

The following are especially noteworthy records:

Carex hyster ic ina Muehl., known previously from a few col lect ions from t h e general v i c in i t y of north Boulder. This species forms a d e f i n i t e zone i n shallow water of the pond margin.
