B. ccerulea , Planch, in Ann. Sc. Nat. ser. 3, ix. 30G, is founded on Bauer’s drawing published 
by Endlicher of R. Brown’s specimens, in which the short anthers are represented as attached 
by the middle of the back, and Planchon thought he recognised these anthers in the specimen 
glued down in the Banksian herbarium. The excellent specimens in Brown’s own herbarium 
show, however, that this is a mistake. The anthers are often as short as figured by Bauer, 
sometimes as long as figured by Salisbury, but always attached by the base, and varying much 
in intermediate lengths in different specimens. Benth. 
Order XLYIII. HALORAGE,®. 
Calyx-tube adnate to the ovary ; lobes 2, 4 or none, or rarely 3. Petals 2, 4 or 
none, valvate induplicate or slightly imbricate. Stamens 2 to 8, rarely 1 or 3; 
filaments short ; anthers erect, 2-celled, opening longitudinally. Ovary inferior, 
flattened or angular, either 2 or 3 or rarely 4-celled, with 1 pendulous ovule in 
each cell, or 1-celled with 1 to 4 pendulous ovules ; styles as many as ovules, 
quite distinct, with papillose or plumose stigmas. Fruit inferior, small, inde- 
hiscent, with 1 to 4 cells and seeds or divisible into 2 to 4 1 -seeded indehiscent 
carpels. Seeds pendulous, with a membranous testa ; embryo cylindrical, in the 
axis of a fleshy albumen ; radicle long, superior ; cotyledons small. — Herbs, often 
aquatic, or undershrubs. Leaves opposite, whorled or alternate, without stipules. 
Flowers small, often unisexual or incomplete, axillary or rarely in terminal 
corymbs racemes or panicles. 
The Order is dispersed over nearly the whole globe. All three Queensland genera have a wide 
range. 
A. True Halorageae. — Flowers with petals, at least in the males, answering to the ordinal 
characters given above. 
Petals, at least in the males, induplicate, keeled. Fruit a nut-like or rarely 
spongy, undivided drupe. Flowers solitary or clustered within each bract, 
along the rhachis of simple or paniculate terminal racemes. Flowers 3 or 
4-merous 1. Haloragis. 
Petals in the males imbricate. Fruit separable into 2 or 4 nut-like carpels. 
Aquatic or mud plants 2. Myriophyllum. 
B. Anomalous genera of a very reduced type allied to Haloragese, but often referred to 
Monoehlamydese. Flowers unisexual. 
Perianth none. Flowers with or without 2 bracteoles. Stamen 1. Ovary 
4-celled, with 1 ovule in each cell. Styles 2. Aquatic or mud plant, with 
opposite entire leaves 3. Callitriche. 
1. HALORAGIS, Forst. 
(From halo, the sea, and rax, a grape-stone.) 
(Cercodia, Murr.; Goniocarpus, Korn.) 
Calyx-tube or ovary with as many or twice as many nerves as lobes, those 
alternating with the lobes occasionally expanded into angles or wings ; lobes 4, 
rarely 3 or abnormally 5, short. Petals as many as calyx-lobes, induplicate and 
boat-shaped or hood-shaped, deciduous, often wanting in female flowers. 
Stamens twice as many as petals or fewer, those opposite the petals and enclosed 
in them always present in complete or male flowers, one or more of the alternate 
ones occasionally wanting, and female flowers usually without any ; anthers 
oblong or linear, deciduous ; filaments short. Ovary 2 to 4 or rarely 5-celled, 
with 1 pendulous ovule in each cell ; styles short and thick, stigmatic at the top,
