It is planted by the natives as a dooryard tree. It 
is very hard to establish the young trees which accounts 
for the small plantings which have been made. (Adapted

Phaseolus lunatus (Pabaceae), 46304. Lima bean. From 
Paraguay. Presented by Mr. Thomas R. Gwynn, Cone epc ion. 
"The Llnconia butter bean is the very finest that I have 
ever come across. It yields in full blast for at least 
eight months and with a good season will give, in a 
climate like this, a year or more in superabundance con- 
tinually, day after day. The plant is extraordinarily 
hardy and thrifty, as neither the extreme drought nor 
the hard frosts of last year put it out of business. 
When I pulled the plants September first they were still 
bearing (not a great deal). I planted this year Sep- 
tember fifteenth, and as we had a splendid year the 
plants are extra fine and are loaded with fruit of all 
sizes, and flowers to the very tip ends. I have them 
planted along a wire fence with poles 12 feet high 
stuck in about one yard apart." (Gwynn.)

leaves are covered with close white hairs.. The fascicles 
of small bell-shaped, dark crimson flowers, with pro- 
truding yellow anthers resting on the downy white young 
leaves, make it a very attractive ornamental shrub.
