Discussion:
Type. Costa Rica. Tui´s, near Turrialba, Pittier s.n. (Herb. inst. physicogeogr. nat. costaric. 11248) (US!, photos NY!, UC!; isotypes BM, K, MO!).
This differs from D. striatum by the traits given in the diagnosis. Riba et al. 387 (MEXU), cited as this species from Veracruz by Palacios-Rios (1992), is probably D. lindbergii; Mickel 743 (NY), also cited by Palacios-Rios as D. striatastrum, is D. striatum. Many of the specimens cited by Palacios-Rios as D. striatum from Veracruz appear to be D. striatastrum, e.g., Finck 26, 148, UC; Purpus 1983, 4353, and 15735 (UC).
