United States, Mexico.

Notes.

Most of the type specimen deposited at B were destroyed in World War II ( Hiepko 1987). Because the holotype of Arenaria leptophylla deposited in B was destroyed and no duplicates of the original material were found in other herbaria such as HAL, where Schlechtendal’s herbarium is housed, we designated the specimen at IEB as a neotype. The species was described based on C. J. W. Schiede 511 from “ Montis Orizabae, ” Veracruz. In the absence of a good quality specimen from near the type locality, we have chosen the above specimen because it corresponds precisely to the application of the name Drymaria leptophylla and is from the neighboring state of Veracruz.
