424 ON FLORAL VARIATIONS IN PLAN'S. 
fig. 24, in which all the petals are marked, there are four complete 
stamens. 
Fig. 4. Flower having three posterior petals and ¢wo anterior petals. Only one 
stamen is developed. The axis is not shown in this case, as its rela- 
tion was not satisfactorily made out, but the attitude of the flower 
was that indicated in the diagram. 
5. Actinomorphic (peloric) flower with four petals, sepals, and stamens, 
All the petals were marked as anterior petals of the normal flower. 
6. Conventional representation of the parts of the flower in the two 
types of Gladiolus gandavensis, showing the planes about which their 
zygomorphy develops in each case respectively.—N.B. The anthers 
are shown in the positions which they commonly assume in the 
expanded flowers of each type. In flowers of type II. the anther 4 not 
infrequently retains its position of origin, facing the segment 4; 
rarely it turns completely round so as to face the segment 2. The 
* unguiculate ” segments are shaded darkly. 
7. Gladiolus gandavensis, Type I., from same spike as fig. 4 (from a 
photograph). 
8. Gladiolus gandavensis, Typs IL, from the same spike as fig. 3 (from a 
photograph). 
Both are from the same side of the spike.
