or vascular cords are observable, which are continued into the style, where they become 

 approximated and parallel. This structure, so nearly resembling that of Compositae, 

 seems to strengthen the analogical argument in favour of the hypothesis of the com- 

 pound nature of the pistillum in that Order, and of its type in phsenogamous plants 

 generally ; Brunonia having an obvious and near affinity to Goodenoviae, in the greater 

 part of whose genera the ovarium has actually two cells with one or an indefinite 

 number of ovula in each ; while in a few genera of the same Order, as Dampiera, 

 Diaspasis, and certain species of Scsevola, it is equally reduced to one cell and a single 

 ovulum." The habit of the Order is much that of Globularia. But its most immediate 

 affinity seems to be collaterally with Nolanads, which it appears to combine with such 

 genera as Phyteuma among Bellworts. Its hypogynous stamens are, however, so 

 peculiar that we may well doubt whether the true affinity of the plant can yet be 

 demonstrated.

M. Alphonse De Candolle suggests an affinity with Leadworts (Plunibaginaceje), 

 in which also there are scarious bracts, and sometimes hypogynous stamens.
