Petit bug

Britton et Rose, The Cactaceae vol. 2 p. 122. Dans la forme texte, en dessous de l'image, il manque la plus grande part de la description d'Acanthocereus horridus.

Une explication?

Philippe.

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
spines 1 to 6, very short, conic, less than 1 cm. long; central spine usually 1, sometimes 2, often very
stout and elongated, sometimes 8 cm. long; flower, including the ovary, 18 to 20 cm. long; tube 4
cm. long, including the funnelform throat 12 cm. long; throat 4 cm. broad at mouth; outer perianth-segments
linear, brown or greenish, 6 cm. long; inner perianth-segments 3 to 4 cm. long; stamens
white; style thick, cream-colored; fruit 3.5 cm. long, light red, glossy, covered with large areoles
bearing white felt; skin thick, finally splitting as the
fruit ripens; pulp red.
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.

Merci pour le texte, même si je l'avais trouvé ailleurs.

C'est surtout que ça me surprenait un 'manque' aussi important.
