Cultivated plants flower mostly in summer.</p><p>Conservation status</p><p>Listed as Vulnerable under the Biodiversity Conservation Act 2016, New South Wales.</p><p>Notes</p><p>Simonachne maidenii shares morphological characters with all of the other taxa in subtribe  Cleistochloinae (Table 1). Notable similarities include  S. maidenii and  Calyptochloa spp. having a contraligule and the stoloniferous growth habit, giving plants a very similar appearance in the field.</p><p>Breeding system</p><p>The type of CL manifested by  Simonachne maidenii fits the category of dimorphic anthers with amphigamy in the classification of CL by Thompson (2017). Axillary CL in  S. maidenii is obligate, whereas in  Ancistrachne, CL is facultative with the CL and CH anthers, the same size fitting the type ‘monomorphic CH and CL anthers’ on the same plant as defined by Thompson (2017).</p><p>Micromorphology and macromorphology of the lemmas and palea</p><p>Simonachne maidenii and  Ancistrachne s.s. differ in the lower lemmas by  S. maidenii having absence of prickles and film of epicuticular wax. Upper lemmas of  S. maidenii have minute longitudinal ridges and lack papillae. Upper lemmas of the terminal spikelets of  S. maidenii are chartaceous to slightly hardened and loosely clasping the caryopsis, whereas for  Ancistrachne s.s. they are hardened, glossy and tightly clasping the caryopsis.  Simonachne maidenii, as for other species in  Cleistochloinae, lacks a lower palea, whereas species of  Ancistrachne, members of  Neurachninae s.s. and the species of  Panicum have a lower palea.  Simonachne maidenii differs from  Ancistrachne by the indumentum on the upper glume and lower lemma and differs from other members of  Cleistochloinae by having an indistinct germination flap on the upper lemma (Tables 1, 3, Fig. 4; Appendices 8, 10–13).</p><p>Abaxial leaf-blade epidermis</p><p>Costal−intercostal zonation conspicuous. Papillae absent. Costal long cells rectangular, much narrower than intercostal; anticlinal walls of intercostal long cells Ω-shaped. Anticlinal walls of intercostal long cells moderately undulating, often irregular with short-wave length. Stomata 38–43 µm long with low triangular subsidiaries, in 2 rows separated by 5–6 files of long cells. Bicellular microhairs 52–56 µm long, proximal cell longer than distal, occasional. Silica bodies in single rows, bilobate and polylobate, 16–25 µm long, common. Hooks present (Appendices 14, 15).</p><p>The shape of the anticlinal walls of long cells in the upper lemmas and the abaxial leaf surface in  A. maidenii differ from those in  A. uncinulata, and, in  A. maidenii, the shapes of these walls differ from each other (Table 3). Such differences in the shape of anticlinal walls of long cells have been reported for some other panicoid grasses (Lu et al. 2009; Harun et al. 2020).</p><p>Transverse section of leaf blade</p><p>C 3; XyMS+. Mesophyll with radiate chlorenchyma; adaxial pallisade chlorenchyma present. Midrib not prominent; with a double bundle sheath; outer complete ring of parenchyma cells and partial inner ring of thick-walled cells with adaxial arc of clear parenchyma cells. Bulliform cells in discrete regular groups; in simple fans. Sclerenchyma accompanying all vascular bundles as adaxial strands and abaxial girders (Appendix 16).</p><p>Transverse section of culm</p><p>Culm examined 0.6 mm in diameter. Outer smallest vascular bundles adjacent to tangential girder sclerenchyma and imbedded in large-celled sclerenchyma. Vascular bundles with a ring of clear parenchyma; three sizes in separate circles, smallest to the periphery. Chlorenchyma in rectangular blocks, 2 or 3 cells deep by up to 10 cells wide; cells with regular size and shape, more or less circular. Inner ground tissue consisting of large thin-walled cells. (Appendix 17).</p><p>The distribution of the bundle sheath parenchyma of  S. maidenii has similarities to the fresh culm sections of  Entolasia spp. prepared for this study.</p><p>Surface of inflorescence culm</p><p>Pilose with tuberculate-based macrohairs up to 2 mm long, muriculate with hooks and scabridulous with prickles. Stomata frequent, similar to those on the abaxial leaf surface. Bicellar microhairs, ~44 μm long, occasional. Silica bodies absent.
