THE CONNECTIVE AND ANTHER 223 



Syngenesious anthers also occur in LOBELIA and 

 others of another family the CAMPANULACE^E, which 

 are not included in the COMPOSITE, because their 

 flowers are not aggregated in heads in the same way. 



In CUCURBITA, CUCUMIS MELO the Melon, and others 

 of the family CUCURBITACE^E both the filaments and 

 the anthers are joined together into one mass which 

 occupies the centre of the flower. (The ovary with 

 its style occurs on separate flowers, not with the 

 stamens.) In some genera of this family, the anthers 

 appear to be doubled back on themselves in a S 

 shape. And in the ASCLEPIADACE^E, they are not 

 only fused all together but also connected to the top 

 of the styles. 



10. The two halves of the anther are usually exactly 

 equal in size, and together form one two-lobed anther. 

 In JUSTICIA, ADHATODA, and a few others, one half 

 of the anther stands a little lower down on the filament 

 than the other, and has a white appendage, or tail, at 

 the base. 



In MILLINGTONIA the Indian Cork-tree, in KIGELIA 

 the Sausage-tree, in TECOMA and in others of the family 

 BIGNONIACE^E, the two halves of the anther are 

 connected to the filament at the same level, but diverge 

 widely to right and left. 



In SALVIA, the two halves are completely separated, 

 and in some species the lower half is sterile, contain- 

 ing no pollen. It may, indeed, be flattened and quite 

 different in shape from the other upper half, so that 

 only the existence of transition species, in which both 

 halves are fertile, shows definitely that it is really 

 a deformed or rudimentary anther-lobe, and that the
