 [Page 14

Erect stems.

Columns are budding only weakly, or not of the all, from the base, 3-4 m tall, 8-10 cm thick, dark green in color.

Ribs: 4-6, generally 5, almost lacking tubercles, wide and blunted to flanks a little bombés, to a thickness of about 3-4 cm.

[??] [Problematic passage. “larges et émoussées à flancs un peu bombés” Thusfar we unable to locate “bombés” in the available dictionaries]

The furrows that separate the ribs are rectilinear [i.e. straight & even].

 [Page 15]

 Areoles: slightly sunken, with a little white wool. They are circular or oval, 1-3 mm long, 1 mm wide, and separated by from 1.5 to almost 3 cm;
The circular flowering areoles have a diameter of about 4-5 mm.

Spines: lacking in the case of large plants or can number from 3-5, brown in color, [awl-shaped and only around 1 mm long] (?)

[Unclear passage: “seulement de 1 mm environ subulés”. www.freetranslation.com gave as “only of 1 mm about subulés”]

Seedlings: Have 6-7 ribs, whitish or brown areoles are 1-1.5 mm in diameter, separated by 3-5 mm, with 7-13 needle-shaped whitish or brown spines, 2-5 mm of long; 1-2 of these are placed as central spines.

Flowers: Generally borne in the neighborhood of the apex and sometimes also lower, 16-20 cm long, fragrant, opening at night and remaining again into the cool hours of morning.

Ovary: Green, with large podaria around 1 cm in diameter, upwards running out into greenish scales and pointed bracts 1-2 mm of length with white woolly hairs; upwards there is also black hairs.

Nectar chamber: White-brownish, tube-shaped, surrounding the style very closely, about 2 cm long, with nectar.

Floral tube: (above the nectar chamber): Has the form of a funnel, 6.5-8.5 cm long and around a 3 cm width on the upper part; bright green in color inside and outside.

 The green scales increase in size while passing from the bottom upwards, to around 2.5 cm long and 1.5 cm wide. The transition regions situated between the tube and the floral envelopes, are reddish-brown.

[Unclear passage: “Les régions de transition situées entre le tube et les folioles du périanthe” (freetranslation.com gave as “The transition regions situated between the tube and the folioles of the périanthe”)

Very curly black and white hairs and wool are present.

Stamens: pale Green towards the bottom and yellowish upwardly, 7-9 cm long, (those of the hymen are 4-5 cm), inserted on a distance of around 4 cm.

Anthers: Brownish.

Style: pale Green, 14-18 cm long, taking into account 2 cm that corresponds to the length of the 12 lobes of the pale yellow and spreading stigma.

Perianth sgements: 6-8 cm long, 2.5-4 cm long with a narrow base. The rounded terminal portions may have or lack small points.
The petals are white and wider at the top.
The sepals are not as wide, they are white with a green midstripe.

Fruit: Green, 4-5 cm long and wide; the zoned surface is analogous to that of the ovary. It has a savory taste.

Seed: 1.75 mm long, 0.75 mm thick, 1.25 mm wide. In the shape of a kidney, glossy, black surface, lightly tubercled. Base is very inclined. Hilium is oval and brownish.

Systematic position: Closely related to the type of Trichocereus bridgesii (SD) BRITTON & ROSE and closer to Trichocereus crassicostatus RITTER spec. nov.

Habitat: Slopes and rocky hills of the mountainous virgin forests of southern Bolivia.

Holotype: Collected in the vicinity of Tapecua, O'Connor province, Bolivia, and deposited in the herbarium of Ultrecht University.

This species was found to exist by F. Ritter in May 1959 and was catalogued under the collection number FR 991.
