Note: There are two dominant varieties of L. punctata in Texas, mucronata and punctata. The difference are the shape of the corm (bulb), mucronata being more or less spherical and punctata being elongated. Also, punctata is more common in the western 2/3 of the state and into the Panhandle whereas mucronata is found in the central part of the state (eastern part of the Hill Country) and further east. Differences in phyllary shape (mucronate vs. apicular tips) is less definitive. The plants shown here could be either variety.
