Quite a few Lobelia flowering in this spot. Plants single stemmed ranging in height from 10-30 cm with no leaves present (withered). Maybe Lobelia simplicicaulis as these are different to earlier observations of L. gibbosa?
Similar to U.dichotoma however U.beaugleholei is often an annual and grows in a completely different habitat. Under closer inspection differences in the flower is the palate which has from 2-11 yellow ridges with U.dichotoma having only 2-3.
