Case 6. Calyx with six teeth, and with a large expansion 
between the upper ones. One margin of this expansion was free 
and inserted within the calyx like a vexillum. This structure 
was probably a union of a vexillum with a petaloid outgrowth of 
the calyx, although no line of junction was apparent. Free 
vexillum none. Stamens ten, united into a split tube. (fig. 70.) 
Case 7. Calyx asin z. Vexilla two, one with a downward 
hook. Stamens eleven, united into a tube. 
Case 8. Calyx asin z. Rest of flower normal. 
Case 9. The tissue of two of the upper sinuses of the calyx 
was expanded into irregular petaloid bodies, the upper one with 
a divergent lateral lobe. Vexilla two, each having the form of 
half a normal vexillum, one with a prominent downward hook. 
Alae abnormally narrow, curved upward and outward, and lack- 
ing the usual overlapping edge. Stamens twelve, of which 
eleven were completely united, the twelfth partially adherent. 
(Figs. 11-13.) 
Case ro. Calyx with a slight petaloid expansion which was 
united edge to edge with the outer vexillum. Vexilla two, each 
having one margin enclosed in the carina. One ala external. 
(fig. 14.) ” 
Case rz. Calyx the same as in z. Vexilla two. One ala 
narrow and much curved upward. Stamens nine united, one 
free, and one nearly free. 
Case r2. Calyx with six teeth. Vexilla two, each with a 
lateral lobe, one lobe unusually large. (Fig. 15. 
Case 13. Calyx teeth six, the lower two narrower and more 
approximate than the others. Vexilla two. Stamens nine 
united, three free. 
Case 14. Vexillatwo. Stamens nine united, and two free. 
Case 15. Vexilla two, each with a lateral basal lobe on the 
upper side. (Fig. 76.) 
Casest6 and 17. Vexilla two, the second having one margin 
enclosed in the carina. Stamens ten united, one free. 
Case 18. Vexilla two, which were slightly united edge to 
edge at the base. Stamens diadelphous, two and nine. (fig. Z 7-)
