Diplocentrus
Toothed Scorpions
Diplocentrus is a genus of scorpions in the family Diplocentridae, commonly known as toothed scorpions. The genus contains more than 60 described species distributed primarily in Central America, Mexico, and the southwestern United States. Species in this genus are characterized by their elongated pedipalps and distinctive tooth-like structures on the chelicerae. The genus includes both mainland and island-dwelling species, with documented occurrences in the Chisos Mountains of Texas and Islas de la Bahía in Honduras.
Pellaea
cliffbrakes
Pellaea is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae, commonly known as cliffbrakes. The genus name derives from Greek 'pellos' meaning 'dark,' referring to the bluish-gray stems characteristic of many species. These ferns are primarily adapted to rocky habitats, including cliff faces, rocky slopes, and bluffs. Molecular phylogenetic studies using chloroplast DNA restriction site variation have clarified relationships within the genus, particularly resolving the P. glabella complex and establishing that P. atropurpurea is sister to this complex rather than the previously hypothesized P. breweri.
