Fig. 1. Sketches of leguminous leaves showing evidence of reduction in compound 

 leaves. A, in Ccrcis canadensis, survival of a terminal leaflet, articulation prominent; 

 B, in a 5-foliolate leaf of Trifolium arvense, reversion of normal trifoliolate to an- 

 cestral multifoliolate; C to H, in leaves of Bauhinia (C, B. saigonensis; D, B. acu- 

 minata; E, B. reticulata; F, B. mollicella; G, B. malabarica; H, B. retusa), a series 

 in connation of two lateral leaflets to form one pseudoterminal leaf, the tip of the 

 rachis still evident in D to G.
