The botanical name is derived from the Greek '''anastomosis''' ''Italic text''(formation of a network), in allusion to the reticulately nerved phyllodes.

Spindly, straggly, multi-stemmed shrubs 1–2 m tall. Bark smooth, brown. Branchlets angled at
extremities but soon terete, marked with short, raised stem projections where phyllodes have fallen,
finely ribbed (often appearing obscurely striate), the ribs dull or shiny (but lacking obvious resin)
and of the same colour as the inter-rib spaces, dark red aging greyish, glabrous or with microscopic,
red-brown glandular trichomes. Stipules mostly caducous, triangular, inconspicuous, c. 0.5 mm long.
New shoots shiny, green except with minute, reddish brown glandular trichomes when very young.
Phyllodes narrowly elliptic or sometimes obovate, mostly dimidiate with lower margin straight or
shallowly convex and upper margin clearly convex, sometimes a few symmetric with both margins
convex, (4–)5–9(–12) cm long, 15–25(–40) mm wide, sometimes interspersed with a few c. 10 mm
wide, l: w = 2.5–4.5(–6), thinly to moderately coriaceous, straight or slightly recurved, green, glabrous;
main longitudinal nerves 2–4 and normally with an additional 2 or 3 imperfect and/or less discrete
nerves parallel to them, not especially prominent (but visible to the unaided eye), plane or slightly
raised (when dry), yellow, not or scarcely resinous, some or all confluent with lower margin of phyllode
for 2–12 mm above the pulvinus, minor nerves anastomosing to form an open, net-like reticulum,
the nerve-islands ±irregularly square to oblong (longitudinally orientated), some or all nerves of the
reticulum commonly lack capping cells and may therefore be somewhat obscure; marginal nerve
discrete but not prominent, yellow to light brown, not or scarcely resinous; apices mucronate, the
mucro triangular, 0.7–1.7 mm long, flattened (not noticeably thickened); pulvinus 2–3(–4) mm long

Gland situated on upper margin of phyllode at distal end of pulvinus or to 2 mm above it, sometimes
absent, sometimes phyllode lamina slightly swollen about the gland. Inflorescences simple, 1 or
2(–3) per axil; peduncles 8–17 mm long, 0.6–0.8 mm diam. when in flower, to 1.5 mm diam. when in
fruit, glabrous except often with scattered hairlets as on receptacle, striate by very fine, longitudinal
furrows when dry; basal peduncular bract single, early caducous, triangular, c. 1 mm long; spikes
10–20(–28) mm long, with flowers rather close together; receptacles c. 1 mm diam., with microscopic,
red-brown glandular trichomes. Bracteoles spathulate, 0.5–1 mm long, claws linear and expanded
into ovate, slightly thickened laminae, some persistent on receptacle after flowers have dropped.
Flowers 5-merous; calyx c. 1/3 length of corolla, gamosepalous, shortly dissected into triangular to
broadly triangular or oblong lobes, calyx tube sparsely hairy (some glandular) to sub-glabrous and
nerveless; corolla 1.5 mm long, glabrous or sub-glabrous but the nerveless or finely 1-nerved petals
with microscopic white villae along their margins towards apices. Pods (dehisced valves plus few
aborted, unopened pods) narrowly oblong to narrowly oblong-oblanceolate, narrowed towards the
base, not constricted between the seeds, 5–10 cm long, 7–10 mm wide, crustaceous to ±sub-woody,
straight, opening elastically from apex with the dehisced valves strongly recurved (often forming a
±open coil), dark brown and sometimes faintly pruinose, glabrous, obliquely nerved with some nerves
sparingly anastomosing, inner surface of valves dark red except for yellow or light brown marginal
nerve; marginal nerve thick and evident but not raised

Seeds (immature, few seen) oblique in the
pods, seated in shallow but distinct chambers each separated by a narrow septum, ellipsoid; ''funicle-aril'' fleshy, white and narrowly turbinate, the funicle straight or sometimes convoluted

== Geographic distribution ==

Occurs in the Kimberley region of northern Western Australia where it is known only
from south of Kalumburu.

Grows on red volcanic soil in open woodland with Eucalyptus tectifica, Corymbia greeniana
and Erythrophleum chlorostachys over Gossypium exiguum, Chrysopogon fallax and C. latifolius

== Identification ==

Characteristic features. Spindly, predominantly glabrous shrubs. Phyllodes mostly dimidiate, moderately
short and broad (mostly 5–9 cm long and 15–25 mm with l: w = 2.5–4.5), with 2–4 main longitudinal
nerves (plus a few imperfect ones) of which some or all are confluent with lower margin of phyllode
at base, minor nerves forming an open net-like reticulum comprising ±irregularly square to oblong
nerve- islands, apical mucro short and not noticeably thickened. Inflorescences simple; peduncles
8–17 mm long; spikes short (10–17 mm long) and rather densely flowered. Flowers 5-merous; calyx
c. 1/3 length of corolla, shortly dissected into triangular to broadly triangular lobes. Pods narrowly
oblong to narrowly oblong-oblanceolate, narrowed towards the base, 5–10 cm × 7–10 mm, crustaceous
to ±sub-woody, straight, opening elastically from apex with the dehisced valves strongly recurved
(often forming a ±open coil); marginal nerve thick. Seeds oblique, seated in shallow but distinct
chambers each separated by a narrow septum

Because of the paucity of collections it is not possible to determine an accurate phenology
for this species; however, three specimens with flowers at anthesis have been collected, one in April,
one in late May and the other in mid-June. The one known fruiting collection, with aborted and
seemingly recently-dehisced pods, was collected in mid-October. This species therefore probably flowers at the end of the wet season and into the early dry season with fruit developing from the
middle of the dry season
