Comments

This stickweed is one of the most commonly occurring and commonly collected species of the Watershed. Lappula redowskii ranges from basin to upper montane, preferring open, dry, rocky slopes. Although native, it is often found in disturbed ground both urban and rural. In the spring, old-timers habitually jerk out plants they run across, before the stickers develop. L. redowskii is found in all states west of the Mississippi. It follows the Rio Grande drainage to within 50 miles of the Gulf of Mexico. The species is quite variable. Note that some authorities treat this taxon as Lappula occidentalis, with two varieties, distinguished by the shape of the prickles on the nutlet: L. occidentalis var. occidentalis, and L. occidentalis var. cupulata
