518 SMIL AX SOLANUM 



mentioned in these notes this species is easily distinguished by the length 

 of the main flower-stalk, which is 2 to 3 ins. long, flattened. Berries black, 

 in. diameter. 



Native of the eastern United States; said by Aiton to have been intro- 

 duced in 1739. The plant has a tuberous root-stock. 



S. ROTUNDIFOLIA, Linnceus. HORSE BRIER. 



A vigorous, deciduous or partially evergreen climber, with slender, round 

 or more or less angled stems, armed with one or two short spines between 

 each leaf; the stems are sometimes 6 or 8 yards long; branches four-angled. 

 Leaves ovate to broadly heart-shaped; 2 to 3 ins. long, often broader than 

 long, with a short abrupt point; prominently five-nerved, smooth and glossy 

 green on both sides; stalk |- to -^ in. long. Flowers greenish yellow, about 

 \ in. across, borne in umbels; main flower-stalk J to in. long, flattened. 

 Berries roundish, black, in. diameter, covered with glaucous bloom, usually 

 three to six of them in one cluster. 



Native of Eastern N. America; introduced in 1760. This is the 

 commonest, most vigorous and hardy of all the smilaxes in cultivation, 

 making a dense thicket of stems. It is the common horse brier or green 

 brier of the United States, where its stems are sometimes 30 to 40 ft. long, 

 stretching from tree to tree. In gardens it may be trained up stout oak posts 

 on which the stumps of the side branches have been left 2 or 3 ft. long. 

 Grown in this way it is very elegant. 



S. SlEBOLDll, Miguel. 



A deciduous or semi-evergreen species, the stems round or somewhat 

 ribbed, and more or less armed with slender prickles; branches distinctly 

 angular. Leaves ovate with a heart-shaped base and a long fine point, five- 

 or seven-nerved, margins minutely jagged; green both sides, i| to 3 ins. long, 

 two-thirds as wide. Flowers in small umbels of four to seven blossoms, green; 

 main flower-stalk ^ to in. long. Berries black, % in. diameter, often in threes. 



Native of Japan; introduced in 1908, perhaps before. It is a little known 

 species, very distinct from S. China, also Japanese, in the smaller black 

 fruits, few-flowered umbels, and triangular-ovate leaves. 



S. WALTERI, Pursh. 



A deciduous climber, with angled stems, armed only near the base ; 

 branches squarish, unarmed. Leaves ovate to ovate-lanceolate, 2 to 4^ ins. 

 long, | to 2-| ins. wide; broadly wedge-shaped to slightly heart-shaped at the 

 base, ending in a short fine point; five- or seven-nerved; smooth and green 

 on both sides ; stalk J to J in. long. Flowers greenish, in short and flat- 

 stalked umbels. Berries bright coral-red, globose, \ in. wide. 



Native of the eastern United States from New Jersey southwards ; 

 introduced early in the nineteenth century; rarely seen now. It is allied to 

 S. rotundifolia, but has narrower, proportionately longer leaves, and is not so 

 vigorous a grower. S. rotundifolia also has black fruits. 



SOLANUM CRISPUM, Ruiz and Pavon. SOLANACE.E. 

 (Bot. Mag., t. 3795.) 



A scandent, quick-growing, more or less evergreen shrub, with downy, 

 scarcely woody young shoots. Leaves ovate, variable in size, usually
