622 HALORAGIDACEAE. [ Haloragis. 
much reduced in size towards the tips of the branches, where they usually 
become alternate, generally sparsely clothed with short appressed hairs, 
sharply serrate; serratures few. Flowers minute, solitary and sessile in 
the axils of the upper leaves or floral bracts, forming slender leafy spikes. 
Calyx-tube broadly oblong, longer than broad; 8-costate, tetragonous ; 
calyx-lobes 4, ovate-lanceolate. Stamens 8. Styles 4; stigmas plumose. 
Fruit ovoid, 4-8-ribbed; more or less rugose or nodular—H. tetragyna

Hooker regarded this as a variety of the preceding species, from which it differs 
in the slender and much-branched procumbent or prostrate stems; and in the smaller, 
broader, and more obtuse leaves, with fewer serratures. I think there can be no doubt 
as to its specific distinctness. 
5. H. depres (Walp. “Sed i (1843) 99.—Stems creeping and rooting 
at the base, ascending and erect above, much branched, slender, wiry, pilose 
with appressed whitish hairs. Leaves usually all opposite, more rarely 
alternate towards the tips of the branches, the lower pairs remote, the 
upper closer together, sessile or shortly peticled, 1-4in. long, ovate or 
broadly ovate to oblong or oblong-lanceolate, acute or subacute, more or 
less pilose with appressed hairs, thinly coriaceous, crenate-serrate or incised ; 
teeth 2-4 on each side. Flowers at the tips of the branches, solitary, 
axillary, sessile, often close together through the shortening of the inter- 
nodes between the upper pairs of leaves, about ~4in. long. Calyx-tube 
tetragonous, 8-ribbed, broadly ovoid, smooth and polished; lobes 4, 
triangular. Stamens 8. Styles 4, large, plumose, exserted between the 
calyx-lobes. Fruit shining, tetragonous, 8-ribbed, smooth and_ polished 
between the ribs or very minutely rugulose——Hook. f. Fl. Nov. Zel. i (1853)

Schindler has separated the Australian and New Zealand plants associated by 
Hooker and Bentham under the name of H. depressa. The New Zealand species has 
rather large tetragonous fruit with decidedly large persistent styles, decurved between 
the calyx-lobes; whereas the Australian plant has small oblong barely tetragonous 
fruit, and the persistent styles are much smaller and erect. Unfortunately, Schindler 
applied the name of depressa to the Australian plant, overlooking the fact that it was 
given by A. Cunningham to the New Zealand species, to which it must therefore be 
restored.
