PLATE IV. 



Figs. 1, 2, 3. Different views of the stamens and stigma of Stylidium violaceum ; 



after Ferdinand Bauer : a a, anthers ; b, a column formed by the union of 



their filaments ; c, a cup-like disk, consisting of the flattened and united 



apices of the filaments ; d, the stigma, the style of which is united with the 



column of filaments through its whole length. Fig. 1. The anthers when 



burst, seen in front ; fig. 3. the same, from behind ; fig. 2. the anthers 



pushed aside, so as to show the stigma. 

 Fig. 4. Stamen of Rhynchanthera cordata ; after Von Martius : a, a minute 



membrane that separates the filament d from the elongated connectivum c ; 



b, the attenuated beak-like apex of the anther, opening by a single pore at 



the point. 

 Fig. 5. Stamen of Lasiandra Maximiliana ; after Von Martius : a, dilated bases 



of the two cells of the anther; 6, pore at the apex, through which the 



pollen is discharged. 

 Fig. 6. Stamen of Glossarrhen floribundiis ; after Von Martius : a, a dilated 



petaloid connectivum, to the face of which the lobes of the anther adhere ; 



6, the filament. 

 Fig. 7. Stamen of Lacistema pubescens ; after Von Martius : a, filament ; 



&, forked connectivum ; c c, separate lobes of the anther. 

 Fig. 8. Stamen of Gomphrena leucocephala ; after Von Martius : a, broad 



dilated two-toothed filament, bearing a linear one-celled anther. 

 Fig. 9. Stamen of Humirium floribundum ; after Von Martius : a, a large 



tuberculated petaloid connectivum. 

 Fig. 1 0. Stamen of a species of Cryptocarya, from Chili, in which the anther 



opens, as in other Laurinese, by valves that roll back when they separate : 



a, one lobe of the anther, with the valve not separated ; 6, the other lobe, 



with the valve in the act of rolling back ; c c, abortive stamens, under the 



form of glands. 

 Fig. 11. Stamen of Berberis vulgaris, exhibiting the same phenomenon : a, valve 



closed ; &, valve separated and recurved.
