"10. Lemaireocereus aragonii (Weber).
Cereus aragonii Weber, Bull. Mus. Hist. Nat. Paris 8:456. 1902.
Columnar, 5 to 6 meters high, dark green with glaucous bands at intervals of growth; terminal branches about 3 meters long, 12 to 15 cm. in diameter; ribs 6 to 8, very large, 2 to 3 cm. high, rounded; areoles about 2 cm. apart, large, brown-felted; spines gray, about 8 to 10, but new ones developed from time to time, acicular, the radial ones about 1 cm. long, one of the centrals 2 to 3 cm. long; flowers 6 to 8 cm. long; ovary tuberculate, bearing clusters of spines; flesh of the fruit white; seeds large, black, 5 to 6 mm. long.
Type locality: Western Costa Rica.
Distribution: Costa Rica.
This cactus is used a good deal as a hedge plant in Costa Rica, much as is Pachycereus marginatus on the table-lands of Mexico. It is the only columnar cactus in Costa Rica. We have had living specimens of it in Washington since 1907, but they have never grown very much.
A cristate form of Cereus aragonii was named as a variety (palmatus) by Weber (Bull. Mus. Hist. Nat. Paris 8:456. 1902).
Illustrations: Boletin de Fomento Costa Rica 4: 117; Iberica 48: 339, both illustrations from the same source as the one used as figure 135.
Figure 135 is from a photograph taken by Otto Lutz at Tres Rios, Costa Rica, 1,350 meters altitude."
