PHASEOLUS 



4. retilBUS, Benth. Metcalfe Bean. Root very large, 

 said sometimes to weigli 30 lbs., ruuniug deep into the 

 ground: stem trailing, roughish; Ifts. rhombic to oblong, 

 mostly obtuse and often retuse, rough on both sides : fls. 

 in loose, interrupted racemes, 

 rather small, purple: pod flat, 

 short, broadly oblong, some- 

 what curved. Tex., west and

south. — Lately recommended as a forage plant in the 

 dry regions of the Southwest. The Ivs. are thick and 

 heavy and well adapted to dry, hot climates. Stems 

 grow 8-10 ft. or more long.

"bush," the Jvs. mostltf pubescent, cult, for food.

slender stems, growing 1-2 ft. tall: Ifts. mostly ovate 

 to rhombic-ovate. 2-3-lobed at the apex for one-fourth 

 to one-half their length, the lobes narrow and obtuse;

stipules small, narrow and pointed : fls. very small, yel- 

 lowish, in heads on the ends of hairy axillary peduncles: 

 pod becoming 2 in. long, nearly cylindrical, glabrous. 

 India, where it is cult, for human food and for forage, 

 but only rarely seen in collections in this covintry. It is 

 said to be able to withstand much dry weather. 



6. Miingo, Linn. Gram. Erect or 

 nearly so, 1-2 ft., stout, with the fur- 

 rowed stems densely clothed with 

 long brown hairs: Ivs. large and 

 long-stalked : Ifts. very broadly 

 ovate or nearly rhomboid-orbicular, 

 usually entire, thin, short-acute: 

 stipules large, ovate ; fls. rather 

 small, yellowish, in a capitate clus- 

 ter of 5 or 6 on the end of tlir 

 stout hairy peduncle: pod 3 in. or 

 less long, nearly cylindrical, some- 

 what curved, bearing 10-15 beans. 

 S. Asia, where it is everywhere cul- 

 tivated for human food.— Rarely 

 seen in this country. In habit it 

 somewhat resembles the Soy bean 

 (Glycine). The slender pod is 

 hairy at first, but the hairs are de- 

 ciduous. It is very variable. From 

 botanists it has received many 

 names. 



Var. gibber, Roxbg. Lvs. and 

 pod, and sometimes the stem, gla- 

 brous.— A domestic form. This is 

 probably the Adzuki bean of 

 Georgeson, Bull. 32. Kans. Exp. 

 Sta., where it is praised for the 

 high quality of the bean. He de- 

 scribes 2 forms, the White-podded 

 and Black-podded Adzuki, both 

 with small red or brownish seeds 

 with truncated ends and a long 

 narrow scar. Pods 3-.5 in. 

 long. 



Var. radiitus, Hook. f. 

 {P. radidtKS, LinD.). Stems 

 twining, all parts densely 

 hairy. 



BB. Pod usually K in. or 

 more broad: plants not- 

 urally c limbing, but 

 giving rise to "bush" 

 forms. 

 C. Beans large and usu- 

 ally flat. 



7. lunitUB, Linn. Sieva 

 or Civet Bean. Figs. 1741- 

 4. Small and slender, usu- 

 ally not climbing very high : 

 Ifts. thin, short and broad, 

 ovate - pointed (except in 

 special forms, as the Willow- 

 leaf) : fls. of medium size, 

 white or whitish, in axillary 

 racemes : pods small and 

 papery, 2-3 in. long, much 

 curved on the back and pro- 

 vided with a long tip, split- 

 ting open when ripe and the Leaf, a very narrow- leaved 

 valves twisting: beans form of tlie .Sieva type : mid-

 tries, ami prized for its earli- 



ness and prolificacy. It gives rise to dwarf or bush 

 forms, as the Dwarf Carolina, Henderson Bush Lima 

 (Fig. 1743). Common in American gardens.

 Lima Bean. Figs. 1742, 1744. Distinguished from the 

 Sievas by tall, robust growth and late ripening: Ifts.
