slit, and subglobose in Boschia, opening by a terminal, circular or 
elliptic pore. Three stages in the evolution of the androecium may be 
traced in both genera: 1, stamens all free; 2, stamens united in 
five phalanges alternating with one or more free filaments ; 3, stamens 
arranged in phalanges which are connate below in a staminal tube. 
The third type of androecium is characteristic of Boschia Mansoni and 
several species of Durio—T. A. SPRAGUE.
