"16027 P argentatum
Nearly pure stand of guarule
on a southeast gentle slope.
Limestone gravel. Plants
variable in size and age
up to 2 ft. high, relatively
uniform. Show little or no
evidence of introgression. Not
much opportunity for
constructive plant selection.
Very dry. Many plants
beginning to wilt. Unable to
tell if this has affected the
seed quality. 6.7 miles north-
west of Ocampo on road to
Sierra Mojada, Coah.
