Discussion:

Chalepophyllum latifolium Standi. Field Mus. Bot. Ser. 7: 379. 1931.

This taxon represents the broadest-leaved variation of the M. talci group. However, some of the broader-leaved variations found on Cerro Sipapo (Paraque) approach it both in leaf-shape and width. With respect to characters of the stipules, calyx, corolla, fruit, and seeds, this broad-leaved taxon cannot be distinguished from M. tatei var. tatei. Because it represents the variation of greater rarity and more restricted distribution, I have indicated it as a variety under M. tatei, despite the publication of the latter name on one page later, as explained in the discussion under M . tatei var. tatei.
