of both genera, I have come to the conclusion that they mus 
be united, even if extreme species in the two genera seem t 
be so unlike each other.  Hoffmanseggia caudata Gray Ws 
more the characters of C@salpinia Palmeri Watson than ay 
species of its own genus. Its broad oval sepals, short-clawet 
elliptical petals, glandless filaments, and broadly ascinath | 
form pod, are characters which bring it very near C. Palmeny 
while the stipitate and black sessile glands, ovate bracts, d& 
ciduous sepals, and somewhat declined stamens, place itin@ 
intermediate position between Hoffmanseggia proper, and 
Pomaria. <a 
Bentham and Hooker have placed Pomaria in Cesalpme 
(which seems to differ from Torrey and Gray’s idea),and thet 
speaking of Hoffmanseggia, say: ‘‘The genus scarcely differs 
from Ceésalpinia § Pomaria in habit, the sepals less imbn- 
cated and the legume thinner.” 
At first sight H. falcaria Cav. seems distinctly sep’ 
from any species of Cesalpinia, but following my classi 
tion through this section to HW. izéricata Brandg., we P®* 
caudata Gray, and very naturally approach the = 
Pomaria. The black glandular section is very near Pon si 
(according to Benth. and Hook.) the legumes taking on Ci 
acters of Cuzlandina, Sappania, etc. a ‘ity ¢ 
Considering all these relations, and the impossibiy 
establishing any sure generic distinctions, since there at 
termediate forms which bridge all proposed distinction,
