268 NOTES ON SOME PORT JACKSON PLANTS, 



vein prominent, the smaller veins very plainly reticulate, the 

 interspaces only slightly white tomentose. 



Spikes cylindrical, usually from 2 to 4 inches long and 1^^ 

 inches wide between the stigmatic tips, very distinctly rufous, 

 which appearance is especially marked before the splitting of the 

 corollas. 



Stjdes not more than 8 lines long and inserted strictly at right 

 angles to the axis of the spike, quite straight and needle-like, 

 except sometimes the stigmatic end, which is slightly bent; the 

 base away from the rather contracted point of insertion, very 

 slightly flattened; the stigmatic end scarcely thickened. 



The segments of the corolla-tube very obtuse, with very short, 

 shining, and closely appressed hairs from base to summit. 



The whorled arrangement of its leaves and their similarity in 

 shape to B. integrifolia place it near to that species. In the 

 latter, however, the young branches are densely tomentose, while 

 the secondary veins of the leaves are almost transverse and com- 

 paratively straight. In B. paludosa the young branches are 

 almost glabrous, and the secondary veins of the leaves are much 

 more oblique with apparently a greater tendency to curve 

 upwards. But the principal differences are in the flowers. In 

 B. integrifulia the styles in the fully developed inflorescence stand 

 away very prominently frum the split segments of the corolla- 

 tubes, more than half an inch, while also there is a very decided 

 tendency for them to curve downwards. Its corolla-segments 

 also cohere; they also adhere to the style, so that it is very easy 

 to pull them out altogether in a little bundle. In B. imludo^a 

 this usually seems not possible, as when the floral organs are 

 pulled away from the rhachis they come in detached pieces; the 

 styles also as previously mentioned are quite straight and exactly 

 at right angles to the rhachis; nor in the freshly developed flowers 

 do the styles stand so far away comparatively from the corolla- 

 segments. 



We may also draw attention to the young inflorescence of B. 

 inteyrijolia in which the unsplit corolla-segments have an almost 

 perpendicular habit caused by the bending of the elongated style.
