Nyctocereus hirschtianus (Schumann) Britton and Rose, Contr. U. S. Nat. Herb. 12: 424. 1909. Cereus hirschtianus Schumann, Gesamtb. Kakteen 130. 1897. Stems columnar, erect, slender, 10 mm. in diameter; ribs 10, somewhat acute, 3 mm. high; radial spines 7 to 9, slender, 4 to 5 mm. long; central spines 1 to 5, the lower one stouter and porrect; flowers probably white, 5 to 6 cm. long, funnelform; perianth-segments spreading, acute; stamens numerous, somewhat exserted; ovary and tube very spiny; fruit not known. Type locality: Nicaragua. Distribution: Known only from the type locality. This species differs from N. guatemalensis in its habit, more slender stem, its spines, which are much more slender and delicate but not as long, and its smaller flowers. Weingart has written extensively (Monatsschr. Kakteenk. 23:108 to 111. 1913) about this species, reaching the conclusion that it and N. guatemalensis are the same. We have both types before us, and feel convinced that the species are distinct. Illustration: Schumann, Gesamtb. Kakteen f. 31, as Cereus hirschtianus.
