angles
notched at intervals of 1 in. Flowers in the notches, 1/2 in. across, white,
produced in August. Fruit a white, Mistletoe-like berry. A curious plant
from Brazil, and introduced in 1836. In stove temperature it forms a
compact pot-shrub, 2 ft. high, and is worth growing on account of its
singular stems.

R. rhombea (diamond-branched).--Stems and branches as in R. crispata,
but without the wavy margins, and with more elongated joints. Flowers
small, white, produced in the notches of the joints in November. Fruit a
shining, milk-white berry. A compact plant from Brazil, worth growing
for its bright green, leaf-like stems. It should be grown in pots, in
stove temperature, and encouraged to form a globose bush.

R. Saglionis (Saglio's); Bot. Mag. 4039.--A tiny plant, similar in
habit to R. penduliflora, but with brown branches, the small joints
angled, and bearing silky hairs. The branches and joints are set at
zigzag angles. Flowers pale yellow, produced in autumn on the younger
joints. Fruits white, Mistletoe-like. A small, delicate plant from
Buenos Ayres, not more than 6 in. high. This species requires stove
treatment.

R. salicornoides (Glasswort-like); Bot. Mag. 2461.--Stem woody when
old, brown, jointed like hens' toes, not quite as thick as a
goose-quill. Branches in clusters; joints 1/2 in. to 1 in. long, the lower
half much thinner than the upper, so that the joints look like a number
of superposed, miniature clubs. Flowers pretty, on the ends of the
terminal joints, yellow, becoming red with age. An erect plant, 3 ft. or
more high, introduced from Brazil in 1830. The joints are clustered on
the upper part of the stem. When in flower in spring this is an
attractive and very remarkable-looking plant. It thrives best in stove
temperature.

R. s. stricta (straight).--This variety has the joints all pointing
upwards, and is much more compact than the type.

R. sarmentacea (runner-stemmed); Fig. 90.--A creeping, prostrate plant,
with round stems as thick as a goose-quill, and attaching themselves to
tree-trunks or other bodies by means of numerous adventitious roots,
which spring from the under side of the stems. Surface of stem furrowed,
and covered with numerous small clusters of short, hair-like, whitish
spines. Flowers 1 in. across, springing from the sides of the stems, with
pointed, creamy-white petals; stamens spreading; stigma erect,
four-lobed. Fruit small, currant-like. This is a pretty little s
