banner is more strongly reflexed in flower. The calyx tube is 
deeper in the tepary, and the two upper teeth are united to form 
one prominent acuminate tooth rather than being separate and 
nearly obscure as in the bean. The lower three teeth of the calyx 
tube of the tepary are also much longer and more tapering than 
those of the bean, being described as acuminate rather than acute 
triangular to obtuse or rounded as in the latter species (fig. 4). 
The bracts subtending the calyx of the bean are large and nearly

orbicular, measuring about 5 mm. in either direction. The cor- 
Tesponding bracts of the tepary are exceedingly small, — 
spicuous, and early deciduous. They are lanceolate in outline and 
are about 1.5 mm. long by o.5-0.66 mm. broad. In this respect 
the tepary resembles the lima bean. The flower of the lima differs 
from that of the bean or tepary in having its banner of a different 
texture and color from the wings, since it contains chloroy phyll and is 
a pale greenish-yellow color with a purple tinge, whereas the banner 
of the other two species is either white or colored in the normal way.
