Bonsoir Philippe,
Ben oui… petit (si on veut!) bug. Incontournable semble-t-il: c'est le problème de l'extraction automatique du texte depuis un pdf, surtout quand le texte "habille" une image.
Voici le texte au complet:
Plants stout, the joints strongly 3-angled or 3-winged, the young growth 5 or 6-angled; wings
with deep undulations; areoles large, 3 to 6 cm. apart; spines brown or blackish when young; radial

cm. long, including the funnelform throat 12 cm. long; throat 4 cm. broad at mouth; outer perianth-segments

Collected in Guatemala by F. Eichlam in
1909 (New York Botanical Garden No. 34788).
It has frequently flowered in cultivation, both
at Washington and at New York.
Here we are disposed to refer E. W. Nelson’s
plant from San Juan Guichicovi, Oaxaca, Mexico,
collected June 21 to 24, 1895 (No. 2729).
Figure 181 shows a part of a joint of the
type specimen.
