and subtropical |discussion=<p>Species 23 (2 in the flora).</p><!-- --><p>Braunia is distinguished from the other two genera of the family in the flora area by the flagelliform-stoloniferous branches emerging laterally from the stem bases or from branch apices, bearing small, distantly spaced, squarrose-recurved, abruptly setaceous-acuminate leaves. The undersides of the mats are a tangle of wiry stolons. The stolons do not appear to be involved in the proliferation of the plant and may have more of a rhizoidal function, perhaps keeping the acrocarpous stem closer to the substrate. The essentially concolorous apices of the leaves are without whitened areas or filiform processes, although occasionally larger leaves will have several hyaline apical cells or chlorophyllose cells with pellucid margins; the apical cells are somewhat longer (3–4:1) in long-acuminate leaves. The leaves are plicate-undulate, like the ridges in a scallop shell. The capsules are not immersed as in Hedwigia, but distinctly exserted. The cells are multipapillose and the papillae are low, irregularly rounded rather than tuberculate or obviously branched. The perichaetial leaf apices are not pilose, with channeled acumina and a sharp apical cell.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Leaf margins recurved proximally, plane distally; distal medial laminal cell walls straight or weakly sinuate; sexual condition autoicous. |[[Braunia andrieuxii|Braunia andrieuxii]] |-id=key-0-1 |1 |Leaf margins recurved to near apex; distal medial laminal cell walls strongly sinuate; sexual condition paroicous. |[[Braunia secunda|Braunia secunda]] |} </div></div><!-- -->{{#Taxon: name=Braunia |authority=Bruch & Schimper |rank=genus |parent rank=family |synonyms= |basionyms= |family=Hedwigiaceae |distribution=Nearly worldwide;mostly tropical and subtropical |reference=None |publication title=Bryol.
