From Backebergs Trichocereus Lexicon, T. glaucus Ritt.—Kakt. u.a. Sukk., 13: 11, 180-181.1962(1)
Bo. forming a bush 1—2 m h., branching from the base; branches 5—8 cm 25, first bluish then greyishgreen; Ri. 7—9, notched; Ar. grey, 1—2 cm apart, to 7.5mm long.; Sp. black, greying; Rap. 7—10, to 1.5cm
long., stoutly acicular, somewhat flattened, sometimes also brown; Csp. 3—6, 2—8 cm long., ± erect Fl. 13—19cm long., perfumed, white or delicate pink; Pet. to 2 cm br.; Sep. pink to ± blood-red; Tu. greyish-green; nectary brownish, to 2.3cm long.; style pale green; Fil. white, greenish below; Fr. grass-green, 4 cm long., pulp white; S. 1.2 mm long., weakly glossy, black.—Peru (Dept. Arequipa, along the lower Rio Tambo, on mountains and in the region of Ilo) (FR 270). (T. uyupampensis v. glaucus ?).
v. (forma Ritt.) pendens Ritt.—1.c.: Ba. hanging, or inclined and ascending; Fl., Fr. and S. unknown.—Chile (coastal cliffs near Arica) (T. uyupampensis Backbg. ?).
Acc. Ritter, this is a survival, only 3 plants having been found. In view of the unusual habit, and the fact that many characters are found in common, these may have been representatives of T. uyupampensis which perhaps once had a much more southerly distribution but, because of the increasing desiccation of the intervening areas (Ritt.), it has since disappeared there; it is the only prostrate or hanging plant of the sort in S. Peru. If my assumption is correct, the type of T. uyupampensis would need to be re-designated a variety, as shown above.
I got these little guys through an online vendor. Is probably not the real Gluaca according to most, just what Knize sells as 'Glauca'. They are most likely peruvianoids. Spikey little buggars already. Be interesting to see how they turn out. Probably isn't really T. Glauca, but should be nice cacti regardless. That's the thing with plants from Knize (KK), they may or may not be what they are supposed to be, but they are still beautiful cacti, whatever they are. Just can't be too fussed about the names ;)
