Lappula occidentalis var. cupulata

This is a common spring-flowering species in rocky areas at low elevations. The spiny nutlets can be a nuisance later in the season. Lappula texana is a synonym; it is distinguished from Lappula occidentalis var. occidentalis by having the spines of the nutlets confluent at their bases. Flowers are usually white, occasionally blue.
