Abstract:—Recent botanical explorations carried out in the Guerrero state for the project Bromeliaceae of Mexico led to the discovery of two new species, both endemic to Guerrero: Hechtia kruseana and H. rosamariae. The new taxa are compared with the morphologically similar: H. anarosae, H. caulescens, H. jaliscana and H. stenopetala. Hechtia kruseana differs from these by the diameter of the rosettes (50-60 cm) and by the length of the staminate and pistillate inflorescences (190-275 cm). Hechtia rosa-mariae differs from morphologically related species by the size of floral bracts (1.5-2.0 × 0.7-1.0 mm) and the length of the petals (3.0-3.2 mm) of staminate flowers; by the length (2.3-2.6 mm) and shape (ovate) of the sepals, and width of the petals (1.7-2.0 mm) of pistillate flowers. Morphological descriptions, images, and a map showing the distribution of the described taxa are included, as well as an identification key for all the species of Hechtia present in Guerrero.
