SpuzrpiopHorum Desyaux, Journ. Bot. iii. (1818), p. 125, t. 6, 
founded on J. esheets Retz, differs from the true Todtgetarse in the 
ovoid globose legume. I have retained it as a section, but the 
ties limits are Corenmbat difficult to define. In J. linifolia the 
also 2-seeded pods occur in the same plant. In J. demissa Taubert, 
for instance, the legume is Senet suborbicular and monospermous 
or ovate-oblong and disperm 
have ventured to ssh e two new groups in the Euindigofere 
foun 
associated with compound leaves, as, for instance, in I. Schwein- 
ey Taubert, J. trimorphophylla Taubert, J. Dupuisii Micheli, 
&e. have named Hereropuyi.z ; the other (for I. strobilifera 
t 
have named OpertirLoRE#. ather associated J. strobilifera 
Hochst. with I. capitata Roteghy i in the Capitate, but the structure 
of the heads of J. capitata is different. Dr. Taubert places I. strobili- 
fera Hochst. in the group she onned but the typical species of this 
group, I. trichopoda, is very differen
