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 through an online vendor. Look to be really nice little plants. Had them for a few months now and are starting to put on some good growth. One of the seedlings is a bit spinier than the other, but they look a close match. I've got a bunch of Glauca seed to try in autumn also. I can't wait to see how these develop, should be interesting. Here's some pics :)
