WILLIAM TBELBASE. 



APIOS (pear, from the Greek, 

 alluding to the shape of the tubers). 

 Legumindsse. Hardy twining herbs, 

 with tuber-bearing roots, infre- 

 quently planted. 



Leaves pinnate, of 3-9 mostly 

 ovate-lanceolate scarcely stipellate 

 Ifts.: fls. in dense, short racemes, 

 papilionaceous, the standard broad 

 and reflexed, keel incurved and 

 coiled; stamens 9 and 1: pod linear 

 and flat, several-seeded. Two spe- 

 cies in E. N. Amer , and 3 others 

 in Asia. 



tuberdsa, M conch. GROUNDNUT. 

 WILD BEAN. Fig. 233. Four to 8 ft., 

 climbing over bushes: root bearing 

 strings of edible tubers, 1-2 in. long: 

 Ifts. 5-7, ovate-lanceolate: fls fra- 

 grant, chocolate-brown, the standard 

 very broad and turned back, the keel 

 long, incurved and scythe-shaped. 

 July, Aug. Common in low grounds 

 and swamps. The fr. often fails 

 to mature. Prop, by the tubers, 

 24 of which should be planted 

 together at a depth of 3-4 in.; also, 

 by seeds. Grows well in the wild 

 border, in any loose, rich soil. Under 

 these conditions, the plant covers a 

 trellis or other support in a com- 

 paratively short time. Dry tubers 

 offered by seedsmen are h'kely to 

 start slowly. The brown of the fls. is 

 a very unusual color in hardy herbs. 2 34 Fruit of Aplec- 

 Likely to become a weed in rock- tram hyemale. 



eries and wild gardens. Nearly natural sizr.
