Perianth-segments usually 5, but sometimes 4 or 6. Stamens the same 
number; filaments short. Nut oblong, black, about }1in. long, peduncle 
much enlarged and thickened, often red and succulent, the perianth-

long; stigma simple; ovule solitary, erect, adnate to the walls of the 
ovary. Fruit a l-seeded berry or drupe, pericarp usually viscid. Seed 
generally albuminous; embryo straight, axile, radicle superior. 
A family comprising 21 genera and about 525 species, chiefly found in the tropical 
or warm regions of both hemispheres, with comparatively few species in the temperate 
zones. The order has no important properties or economic value, and the common 
mistletoe is the only species of any repute. Of the 5 New Zealand genera, Tupeva is 
endemic; the remaining two are widely distributed in both temperate and tropical 
climates.

An important series of memoirs on the structure and classification of this family, 
by the French botanist Van Tieghem, was printed in the Bulletin of the Botanical 
Society of France for the years 1894-96 (vols. xli-xliii). One of these memoirs, 
entitled “‘ Sur les Loranthoidées de la Nouvelle-Zelande,’’ deals specially with the New 
Zealand species, and contains many original and valuable observations. Van 
Tieghem’s researches have to a large extent supplied the basis of a new classification 
of the family proposed by Engler in ‘‘ Die Pflanzenfamilien *’ (Nachtrage, i, 124), 
although most of his genera are reduced to the position of subgenera or sections. The 
following arrangement of the New Zealand species is based largely on Engler’s views. 
1. ELYTRANTHE Blume. !% 
Parasitic shrubs. Leaves opposite, rarely alternate, usually coriaceous. 
Flowers hermaphrodite, often brilliantly coloured, red, orange, or yellow, 
rarely green ; sessile in the axils of the leaves, or more generally arranged 
in short spikes or stalked clusters. Perianth double ; outer (calyx) adnate 
to the ovary, limb obscurely sinuate or truncate; inner (corolla) tubular
