Comments On Specific Species Lotus scoparius var. brevialatus. The plants at this location are babies, and hence cannot be identified to the variety. The variety given is that of some plants farther along the trail.
Melilotus indica. The first specimen here didn't have blooms yet, but within a short distance are many plants of this species.
