This seems to be an unusual color phase of this species. There were several plants in this lot, all with cream flowers. Elsewhere in area there were one or two plants in some populations of hundreds of 'normal' yellow-flowered plants.

voucher 14399 (NMC); two intergrading phases seem to be in Las Cruces area, this one short, scapose, and difficult to separate from P. grandiflorus in FNA. Root, however, is consistently thick and napiform
