. Ornamental shrubs of the United States (hardy, cultivated). Shrubs. ARALIA 211 eral species found in the Mississippi Valley, Western Pkicklt ' Pear ' (334) âOpuntia Eafinfequii â etc. MamilUria. The next group of cacti in number and variety of forms â wild in the United States are more or less rounded or oblong masses hav- ing the surface entirely covered with spiny-tipped tubercles (raammillse) ; as, Purple Cactus (335) â Mamillaria vivfpara. Of this group there are a dozen wild and many cultivated species. The hundreds of species in cultivation belong to these two and some dozen other genera. There is a group very popular in cultivation which has broad flat leaf- like growths for stems, thus called Leaf Cactus â Phylloodotus. A few of these are night-blooming of great beauty and delicious perfume. Though some of these . are wild in Cuba, probably none can be grown out of doors except in southern California. [Cuttings.] Alalia. The Aealias proper form a large group (40 species) of mainly tropic plants with com- pound leaves and clustered small flowers; two of the species are shrubs or small trees nearly hardy North. Hercules' Club or Devil's Walking-stick, and Angelica- tree are beautiful prickly shrubs or small trees with very large com- pound leaves 1 to 4 feet long, with 75 to 200 blades and enor- mous clusters of'white flowers, in August. The two species are the American Hercules Club (336) âAralia spin6sa,âand the Chinese An- gelica-tree â Aralia chin&sis, â either of which occasionally grows to the height of 40 feet. The American is apt to be the more prickly, on both stem and leaves. The blades of the bipinnate leaf of the American are usually smaller, 1^ to 3J inches long, and short-stalked, while the Chinese blades are larger, 3J to 6 inches long, and about stemless. Neither are fully hardy North without some protection, but the Chinese is the more hardy. In the American species the veins peculiarly curve near the margins, while those of the
