Ignacio Bolívar
Al2(PO4)(OH)3 · 4-5H2O
Pale greenish-yellow
Specific Gravity:
Crystal System:
Named by L.F. Navarro and P.C. Barea, P.C. in 1921 in honor of Ignacio Bolivar (9 November 1850, Madrid, Spain - 19 November 1944, Mexico City, Mexico), naturalist, entomologist, and director of the National Museum of Natural Sciences in Madrid.
See also kobokoboite.

Possibly only a variety of evansite (if bolivarite was formally discredited, evansite would have priority as the species name).
