-PortulacecB.] FLORA OF TASMANIA. U3 
a coriaceous, ovate, hispid or spinous nut, with a pendulous seed. (Name from VUMtj I MM**; from the 
appearance of the species, which are allied to the Cucumber.)

Disteib. South-eastern Australia, New Zealand, Norfolk Island, and the coasts of North and South 
America. 
A scrambling, herbaceous, glabrous or pubescent plant, with stems 2-4 feet long, most hairy at the nodes.— 
Petioles 1 inch long. Leaves about 2 inches broad, cordate at the base, five- to seven-lobed ; lobes broad, acute or 
acuminate, the point of the middle lobe often elongate, all irregularly toothed. Peduncles of the male flowers 
shorter than the petioles. Ovary hispid with barbed bristles. 
Nat. Ord. XXXIII. PORTULACEyE. 
This Natural Order, which in De Candolle's system is placed in Calyeijloivr, is in many respects allied 
to Caryophyllea : from Ficoidea it hardly differs. There are very few Australian genera, and about 3d 
species, amongst which there are, besides the following, the tropical Asiatic Trhmthnna d 
lotoides, Sesuvium Portulacastrum, and Mollugo Spergula. Of Talinum nearly 20 are known, chiefly natives 
of South-west Australia. 
Gen. I. CALANDR1NIA, //. P. K. 
Calyx persistens, bipartitus. Petala 3-10, subhypogyna, libera v. ima basi connata, membranacea, mox 
gelatinoso-confluentia, ovarium tegentia. Stamina 3-15, petalis subopposita et basi iis coluerentia. Ova- 
rium liberum, 1-loculare. Ovula plurima, columellas centrali funiculis liberis inserta, amphitropa. Stylus 
filiformis, 3-partitus, lobis intus stigmatosis. Capsula 3-valvis. Semina plurima, lenticularia. Albumen 
farinaceum. Embryo periphericus. — Herbs succulents; foliis attends, mttytrrmit, tssn^ulatis ; floribus 
s v. oppositifoliis. 
The genus Calandrinia (which hardly differs from Claytonia) is almost exclusively American, the majority of 
the species being extratropical South American. — Cah/.r persistent, two-parted. Corolla usually of five, membra- 
nous, hypogynous petals, more or less united at the base, often coalescing after flowering. Stamens usually five. 
opposite the petals, and united to their bases. Ovary one-celled, with many ovule<, attached !>\ long funiculi to a 
basal, free placenta. Stigma* three. Gapnde threc-\.ihed. with several - ag farinaceous 
albumen. (Named in honour of J. L. Calandri,ii, a Genevese Botanist.) 
, calyptrata (Hook. fil. Ic. PL t. 296) ; annua, caule gracili ramoso, foliis parvis 
lineari-spathulatis superioribus minutis bracteaeformibus, pedunculis axillaribus post anthesin deflexis,

Distkib. South-eastern Australia, King George's Sound ? 
The only other Australian species known to me is the C. pygnuza of F. Mueller, from Victoria. There are 
fine specimens in Herb. Hook, from Baxter, marked as King George's Sound, but as it has not since been found in 
South-western Australia, and as several of that collector's tickets are erroneous, I am in doubt about the distribu-
