Arr. LXXIX.—On the Fertilization of Selliera. By T. F. Onxzsxuas, F.L.S. 
[Read before the Auckland Institute, July 3rd, 1876.] 
Tue singular cup-shaped covering, generally known as the indusium, that 
‘surrounds the stigma in the Goodeniacee has long been recognised as play- 
ing an important and probably somewhat varied part in the fertilization .of 
the plants composing the order ; but nevertheless, so far as I am aware, no 
one has yet indicated the exact way in which this takes place in any one 
species. As one member of the order— Selliera radicans—is abundant near 
Auckland, I have been enabled to make a few observations that bear upon 
the subject, and consequently take this opportunity of placing a resumé of 
the results obtained before the Institute. 
Selliera radicans is a common plant in salt marshes along the whole 
of our coast-line, but is rarely found inland. It has a stout creeping stem, 
thick and succulent dark green leaves, and small white flowers, that are 
abundantly produced during the whole of the summer months, often whiten- 
ing a broad band near high-water mark at the head of many of our shallow 
bays and inlets. The corolla is split to the base at the back, the five lobes 
all turning to the front, thus giving the flower a peculiar one-sided or incom- 
plete appearance by which the plant can be readily identified. 
If a young flower-bud, some days before it is ready to expand, is exa- 
mined it will be found that the corolla lobes cohere by their edges, that is, 
are valvate. The five stamens form a ring in the centre of the flower, 
closely surrounding the style, than which they are a little higher. The 
style, as is usual in the order, is terminated by the widely expanded cup- 
shaped indusium, in the base of which the stigma, as yet quite young and 
immature, is hidden. As the flower approaches expansion, the stamens, at 
first erect, arch over the indusium; each anther case splits along its inner
