part of the funiculus, runs around the seed; the bony coating very thick, albumen very scant, 
cotyledons contrary to the side of the embryo (as normally in most Opuntie). Our plant is closely 
allied to O. cylindrica, which, like it, comes also from the west coast of South America. 
The Cylindropuntie differ very materially from the common flat-jointed Platopuntia, not only 
by their external form but also by the character of their seed, which is destitute of the broad rim or 
commissure of the Platopuntia seed. They form three natural sections. 
Tunicate.— Spines mostly numerous and very irritating, the larger ones covered with a 
loose shee: seeds with a comparatively large albumen. Plants usually erect, often tall, wood 
reticulated, files a very hard skeleton. Peculiar to Mexico, and especially to the southwestern 
parts of the United States. 
2. Clavate.—Spines without sheaths, generally annulated, and the larger ones compressed ; 
seed as in the last. Growths low, czspitose, without a solid skeleton. In the same regions as the 
last, perhaps also in South America. 
3. Pachysperme.—Spines without sheaths, terete; leaves often somewhat persistent; seeds 
thick in proportion, albumen often very scanty, or scarcely any ; wood unknown; growth tall or low. 
South America, Of this section I could only study O. subulata, cylindrica, and vestita, of the West 
Coast, and with red flowers. Perhaps the yellow-flowering O. Salmiana of Brazil also belongs here, 
and also the different South American Opuntia classed as Ovate; the Platacanthe, with flat, flexible 
spines, I do not know at all; they may form a fourth section.* — Gardeners’ Chronicle, May 19, 1883,
