146 FLORA OF TASMANIA. [Ficoidea. 
Hab. Very abundant at Georgetown, in wet hollows, Gum. — (EL Oct.-Feb.) 
Distrib. South-eastern and south-western Australia. 
A very distinct little species, 1-2 inches high. Stems erect, dichotomously branched. Leaves oblong, blunt. 
Flowers pedicelled, some of the pedicels very long and slender. Flowers large for the size of the plant. Sepals 
four, oblong, acute, minutely ciliate. Petals four, rather smaller than the sepals. Scales 0. Carpels linear-oblong, 
rostrate, mauy-seeded, about as long as the sepals. 
4. Tillaea (Bulliarda) recurva (Hook, fil.) j csespitosa, caulibus elongatis parce ramosis, foliis an- 
guste lanceolatis linearibusve acuminatis, floribus tetrameris axillaribus solitariis pedicellatis nutantibus, 
pedicellis foliis brevioribus, sepalis ovato-oblongis acuminatis petalis lanceolatis sequilongis, squamis hypo- 
gynis liueari-spathulatis ovariis recurvis rostratis dimidio brevioribus. — Tillsea verticillaris, Hook. Ic. PL

Hab. Common in bogs and inundated places throughout the Colony, as at Circular Head, the Derwent, 
Launceston, etc., Gunn.—{Yl Oct.-Feb.) {v. v.) 
Distrib. South-eastern Australia. 
A wry distinct species, belonging to the section Bulliarda, with scales at the base of the carpels. Stems 
sometimes floating, 6-10 inches long, in shallow water or marshes quite prostrate and short. Leaves f-lf 
inch long, linear-lanceolate or linear-acuminate, the nerves in the broader-leaved specimens recurved. Flowers 
inclined or nodding, on slender, axillary, solitary pedicels, shorter than the leaves. Sepals four, with acuminate, 
recurved tips. Petals lanceolate, shorter than the sepals. Carpels produced into recurved beaks, twice as long as 
r !i'' spntlmlutc In populous scales. 
Note. The Tillaa 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, hypogynous scales.

The rarity of succulent plants in Australia has been alluded to under the Order Crassulacea. One of 
the Tasmanian Mesemoryanthema is confined to that Colony and Australia, and the other is found in New 
Zealand also. Of Tetragonia, the other genns, of which numerous South African species are known, there 
are in Australia only the two Tasmanian species.

This very extensive Sooth African genus may be recognized by its fleshy habit, its sepals being more or less 
united together, and with the ovaries ; by the numerous bnear petals often in several rows, and stamens ; and by 
the carpels being all confined into a few- or many-celled, many-seeded fruit, dehiscing along the top of each cell, and 
bearing free rtigniata.-0«fc, on long cords, numerous. (Name from ^een^ca, midday, and avSos, flower ; from 
many species opening their flowers only at midday.)
