Strongly inclined to suspect that T. impUxicoma is the male plant o f li.— Stems decumbent, several feet long,
branched, brittle, covered with yellow bark. Leaves petiolate, 1 4 -2 4 inches long, ovate, ovate-triangular, or rhomboid,
acute or obtuse, quite entire, sometimes concave at the base, when they are almost hastate, pale gi-een.
Flotcers solitary, axillary, on short peduncles, 4 inch long. Drupes nearly 4 inch long, with four horns, and sometimes
four other smaller ones alternating with them.— Tiiis plant is used as a spinach in New Zealand, and is very
palatable; it sometimes bears flowers at the tops o f the horns of the fruit.

Having never found any o f my numerous specimens o f this plant, from Tasmania or Australia, to bear fmit, I
am inclined to suspect that it is the male plant o f T. expama. I t varies extremely in the size of its leaves, those o f
large-leaved specimens equalling the T. expansa, from which however it usually differs in the smaller size of all its
parts, uarrower, lauceolate or oblong-rhomboid leaves, and long, slender peilicels. In its Hve state the surface of
the leaves and young stems is covered with buUate watery cells, giving a crystalline look to the whole, whence its
name of “ Ice Plant.”

This Order, or Suborder o f S a x i/ra g e a , as it is considered by many, differs from th e latter in its
shrubby or arboreous habit, persistent foliage, usually opposite leaves, aud interpetiolar stipules. Tetra-
c a rp a a , however, a doubtful member o f th e Order, has exstipulate, alternate leaves, and Bau era , an
anomalous member, has no stipules. The greater number o f th e speeies are natives o f the Southern
Hemisphere, where they may be regarded as r epresenting th e S a x ifra g e s o f the north temperate zone,
which are almost entirely absent. There are seven or e ig h t Australian species o f the Order, be lon g in g to
almost as many g en era ; th ey are almost exc lusively confined to the east coast and Tasmania.

This curious plant usually forms a straggling bush 8 -1 0 feet high, but also attains a height of 6 0 -7 0 feet,
Hiih a trunk of 4 feet in girth. Everywhere quite glabrous.— and branches very tough, covered with shining
bark. Leaves 1 4 -2 4 inches long, lanceolate, obtuse, shortly petioled, obtusely serrate, deep gi-een, coriaceous,
sliining; stipules lanceolate. Flowers axillary, small, solitary or few together, shortly peduncled, 4 inch diameter.
Sepals four, spreading, connate at the base, lanceolate, valvate, pubescent witliin. P eta ls much smaller than the
sepals, inserted into a lobed disc. Stamens inserted into the disc ; filaments slender, as long as the sepals ; anthers
cordate, produced into a long point. Ovary free, two-celled, with two diverging, slender styles. Ovules few, pendulous
from the dissepiments o f the ovary. (Name from avoSos, difficult o f access, and ircroXov, in allusion to the
small petals.)

This pretty and very curious genus is confined to South-eastern Australia and Tasmania ; several species have
been described, but they are probably all reducible to one. I t bas no immediate allies, and has by some been considered
the type of a distinct Natm-al Family.— Small, stragghng or subscandent shrubs, with opposite, exstipulate,
ti-ifoliolate leaves, and axillary, one-flowered, solitary peduncles. Flowers wliite or pink. Calyx with six to ten
spreading lobes. Fetals six to ten, perigjuious. Stamens numerons, perigjmous, with slender filaments attached
to the back of the anthers, whose cells are united throughout their length, and blunt. Ovary adnate with the base
of the calyx, two-celled, with many ovules and two spreading, slender styles. Capsule two-lobed, with two cells
and many seeds, bursting along the top of each cell. (Named in honour of the brothers Francis and Ferdinand
Bauer, the celebrated Botanical painters.)
