A parasitic shrub; branches terete, jointed. Leaves opposite or 
alternate, flat, broad or narrow. Flowers dioecious, in small axillary 
and terminal panicles. Perianth-tube of the male flowers very small, of 
the female flowers adnate to the ovary; limb 4-partite, rarely 5-partite. 
Stamens in the male flowers affixed to the base of the segments; filaments 
long, filiform ; anthers ovate-oblong. Ovary in the female flowers inferior, 
ovoid; style short and thick; stigma obtuse. Fruit a subglobose 1-seeded 
berry ; mesocarp succulent and viscid. Seed globose; albumen copious, 
fleshy ; embryo almost terete. 
The genus is limited to a single species, endemic in New Zealand. 
1. T. antarctica Cham. and Schl. in Linnaea, in (1828) 203, — 
A small branching shrub 2-3 ft. high; bark pale; branchlets finely 
pubescent. Leaves very variable in size and shape, $-24in. long, from 
broad ovate-rhomboid to elliptic- or oblong-lanceolate, acute or obtuse, 
narrowed into short petioles, pale-green, rather thin; veins faint but 
evident, anastomosing. Panicles shorter than the leaves, 6—12-flowered ; 
peduncles and pedicles slender, pubescent. Flowers small, ¢in. diam., 
greenish-yellow, often very abundantly produced. Segments of the male 
perianth linear-oblong or oblong-spathulate, of the female narrower and 
more acute. Stigma large, globular, obscurely lobed. Berry about }in. 
diam., white or pink spotted with darker pink; pulp extremely viscid.—

Van Tieghem draws attention to the fact that this species is not simply dioecious, 
yf s described by Hooker, but consists of three sorts of individuals—hermaphrodites,. 
males, and females. This peculiarity was first pointed out by A. Richard, from Foster's 
J: manuscripts (Flore Nouv.-Zel. 269).

CoM we Tupeia is occasionally doubly parasitic. Many years ago Kirk recorded an instance 
wn Ww yf where it was parasitic on Elytranthe, growing on Nothofagus. Quite lately Mr. W. A. 
pie omson has brought under my notice an instance where it was growing on Loranthus 
gt mic Nahe, in its turn parasitic on the common hawthorn !

5. KORTHALSELLA Van Tiegh. )%'\\c . 
Parasitic shrubs, often of small size; branches opposite, divaricate and. 
dichotomous, flattened or ‘terete, jointed; leaves wanting or reduced to 
minute scales. Flowers monoecious, very small, arranged in whorls or 
spikes at the top of the joints of the stem or branches. Perianth-tube of 
the male flowers very short and solid; of the females adnate to the ovary, 
limb 3-4-partite. Stamens 3-4 ; anthers 2- celled. Ovary inferior ; stigma 
large, sessile. Fruit a 1-seeded berry, usually crowned by the remains of 
the perianth,
