D i s t r i b . South-eastern Australia.
A veiy distinct species, belonging to the section Bulliarda, with scales at the base o f the carpels. Stems
sometimes floating, 6 -1 0 inches long, in shallow water or marshes quite prostrate and short. Leaves 4 -1 4
inch long, linear-lanceolate or linear-acumiiiate, the nerves in the broader-leaved specimens recurved. Flowers
inclined or nodding, ou slender, axiUaiy, solitaiy pedicels, shorter tban the leaves. Sepals four, with aciuuinate,
recurved tips. P etals lanceolate, shorter than the sepals. Carpels produced into recurved beaks, twice as long as
the spathulate hjq)ogynous scales.
N o t e . The T illa a moschata. Hook, fil., a very common New Zealand and Antarctic plant, has not yet been
met with in Tasmania, but may be expected to occur on the south coast ; it generally grows on maritime rocks,
and has oblong leaves, rather large white or pink flowers, and cuneate, hypogj'nous scales.

The rarity o f su c cu len t plants in Australia has been alluded to under the Order Crassulacea. One of
th e Tasmanian Mesenihryantkema is confined to that Colony and Australia, and th e other is found in N ew
Zealand also. Of T etragonia, th e other genus, o f which numerous Sou th African species are known, there
are in Australia only th e two Tasmanian species.

This very extensive South African genus may be recognized by its fleshy habit, its sepals being more or less
united together, and with the ovaries ; by the numerous linear petals often in several rows, and stamens ; and by
the carpels being all confined into a few- or many-celled, many-secded fruit, dehiscing along the top of each cell, and
bearing free stigmata.— Ovules on long cords, numerous. (Name from fic<rqpfpui, midday, and avdoi, flower ; from
many species opening their flowers only at midday.)

D i s t r i b . South-eastern and South-western ? Australia.
A common sea-shore plant, the fmit of which is edible and agi’eeable, about the size of a good gooseberry ; it
may be readily recognized by the fleshy, linear, triangular, opposite leaves, 1 -3 inches long and 4 inch broad.
Flowers solitary, terminal, on thick peduncles, 14 inch across. Sepals rounded. Petals very numerous, slender,
linear.

I have seen the flowers only of this species sent by Gunn, with notes, from which it appears that there is so
little reason to doubt its being identical with the M. australe that I have described it as above, from Australian and
New Zealand specimens. I t is a smaUer and more slender plant than M. aquilaterale, with narrower, smaUer, less
linear or oblong leaves, longer, elavate peduncles, and smaUer flowers.

This genus is almost confined to the sontbera hemisphere, one speeies alone having hitherto been found in the
North Pacific ; the majority are natives o f South Africa. Procumbent or climbing, littoral, herbaceous or somewhat
slirubby plants, with alternate, petiolate, fleshy leaves, and axiUary, peduncled flowers.— Oalyx-tuhe adnate with the
ovarj', four-angled; limb six-lobed. Petals 0. Stamens foui- to twelve. Styles three to eight, short. Fruit au
obconic, four-angled drape, with a fleshy, green sarcocaip, and a bony eudocaip, often produced into four or more
lateral horns, three- to eight-eeUcd, with a pendulous seed in each cell. (Name from rerpa, four, aud yoivia, an
angle; from the four-angled calyx.)

Gunn’s specimens precisely accord with the figure of De CandoUe (‘ Plantes Grasses’), who quotes the Japan
plant as being the same; they are furtlicr identical with South American specimens, but the New Zealand ones are
considerably smaUcr, with rather longer peduncles and smaUer flowers and fruit, precisely according n ith Bonin
