Elizabeth Juliana Sabine translation
p. 19.—“The Melon-Cactus.”
The Cactus melo cactus is often 10 to 12 inches in diameter, and has usually 14 ribs. The natural group of Cactaceæ, the whole family of Nopaleæ of Jussieu, belong exclusively to the New Continent. The cactuses assume a great variety of shapes: ribbed and melon-like (Melo cacti); articulated or jointed (Opuntiæ); forming upright columns or pillars (Cerei); serpentine and creeping (Rhipsalides); or provided with leaves (Pereskiæ). Many extend high up the sides of the mountains. Near the foot of the Chimborazo, in the elevated sandy plain around Riobamba, I have found a new kind of Pitahaya, the Cactus sepium, even at a height of 10,000 (10,660 Eng.) feet.
