We report the Spitzer Infrared Spectrograph (IRS) observations of threeevolved stars: IRAS 16456-3542, 18354-0638, and 23239+5754. The 9.9--37.2umSpitzer/IRS high resolution spectra of these three sources exhibit rich sets ofenstatite-dominated crystalline silicate emission features. IRAS 16456-3542 isextremely rich in crystalline silicates, with >90% of its silicate mass incrystalline form, the highest to date ever reported for crystalline silicatesources.
