Lemaireocereus humilis Britton & Rose
Publication The Cactaceae 2: 101, fig. 149-151 (1920).
"20. Lemaireocereus humilis sp. nov.
Stems weak, forming dense thickets, dark green, 1 to 4 meters long, about 4 cm. thick, usually with few branches or none; ribs 3 or 4, sometimes 6, more or less interrupted, little undulate; areoles borne in the depressions of the ribs, large, white-felted, bearing spines only in the lower part; spines 5 to 8, brown, becoming white, acicular, 1 to 2 cm. long; flowers greenish white, about 6 cm. long; outer perianth-segments linear-oblong, spreading; ovary with small scattered scales, at first without spines; fruit very spiny, spherical, 4 cm. long.
Collected by H. Pittier at Venticas del Dagua, Dagua valley, Western Cordillera of Colombia, altitude 700 to 1,000 meters, February 1906, and described from a plant collected by him (New York Botanical Garden, No 34794) and from his field notes and detailed and habit photographs. It is called tuna colorado.
This plant is quite different from the other species in its slender stems with very few ribs and in its tendency to form dense thickets, but it has the characteristic flower and fruit of this genus.
Figure 149 is from a photograph taken by Henry Pittier at the type locality; figure 150 shows a flowering branch, and figure 151 shows details of the type."
Type: Pittier s.n., en culture, NYBG 34794, Colombie, vallée de Dágua, Venticas del Dágua, 700-1000m d'altitude, février 1906.
humilis: du latin humilis, bas, près de la terre, en référence au port de la plante.
