52 NATIVE HONEYSUCKLES OR BANKSIAS. 
very unequal lobes, indicating the four partly connate sepals (or 
petals), silky outside, glabrous inside. Anthers oval, almost 
sessile in the cavities near the summits of the sepals. Style not 
much longer than the calyx, glabrous, persistent. Stigma almost 
lateral, roundish-oval. Fruit provided with a long special stalklet, 
bivalved, compressed, oblique, oval, protracted at the base, 
scarcely half an inch long. Seeds oblique-ovate, plan-convex, 
with a very narrow membraneous margin. Albumen none. Coty- 
ledons straight; radicle basal, very minute.

In comparing the flowers of a Mistletoe (see Fig. XIX.) with 
those of a Grevillea and of many other proteaceous plants, a 
great resemblance in structure must be apparent, particularly 
when the floral envelope of the Proteacee is regarded as consisting 
of petals (not sepals). This view seems to receive confirmation 
from some Grevilleas, like G. Huegelii, in which a distinct 
calycine base of the flowers with an adnate gland is by an oblique 
descending line separated from the petaline portion of the flowers. 
It has been shown already, that in the allied order of Santalaceze 
genera are contained as well with superiorly as inferiorly placed 
fruits ; hence merely the inferior ovary of Loranthacez and the 
superior ovary of Proteacez place these orders not so far apart as 
other families of plants, differing in these respects and for this 
reason brought in different series, for instance those of the 
Thalamifloree and Calyciflore. The contiguous contact of the 
floral lobes (called valvular preflorescence) is the same in all 
Loranthacee, Santalaceze and Proteacez, and these orders agree 
likewise in having their stamens opposite to the petals, not alter- 
nate as in the majority of dicotyledonous orders. The habit of 
the terrestrial Nuytsia of West Australia and Atkinsonia of New 
South Wales among Loranthacee is quite that of proteaceous 
shrubs. The presence of petals not absolutely necessitates the 
development of a calyx also, as may be seen among Victorian 
plants in a species of the rutaceous genus Hriostemon (EH. pleu- 
randroides from the Grampians), in which the calyx is totally 
obliterated. The unexceptional uniformity of four sepals or petals 
in so vast an order as Proteaceze is the only instance of a very
