The central leaves are inserted dorsally or ventrally and the costa is almost aligned with the central stem axis; in lateral leaves the insertion line surrounds the stem, and thus costa alignment is displaced toward one side. Lateral leaves can be distinguished as dorsal or ventral; if the leaf is inserted dorsally (with costa on the dorsal side), then there will be a small fold on the ventral side. The secondary stems are perpendicular to pendent, and unbranched, irregularly branched, or pinnate. The primary stem leaves are erect to erect-spreading, triangular, lanceolate, broadly ovate, or obovate, with margins recurved to plane basally and entire to slightly serrate; the apex is acute, narrowly acute, or sometimes long-acuminate; and the costa is absent, single, or double and short. The alar cells are undifferentiated to differentiated and short-quadrate; the basal laminal cells are usually rectangular; and the distal medial cells are fusiform to linear. The inner perichaetial leaves have margins that are entire to slightly serrate at the abruptly to gradually acute apices, costae to mid leaf or absent, and fusiform to linear distal medial laminal cells. The capsules are erect; the exostome teeth are sometimes perforate.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Leaves flat |[[#key-0-2| > 2]] |-id=key-0-1 |1 |Leaves undulate |[[#key-0-3| > 3]] |-id=key-0-2 |2 |Plants 3.5-4 cm; central stem leaves oblong; apices rounded-apiculate. |[[Neckera complanata|Neckera complanata]] |-id=key-0-2 |2 |Plants to 2 cm; central stem leaves ovate to obovate; apices obtuse to broadly acute. |[[Neckera besseri|Neckera besseri]] |-id=key-0-3 |3 |Capsules exserted; leaf margins serrate to dentate at apex. |[[Neckera douglasii|Neckera douglasii]] |-id=key-0-3 |3 |Capsules immersed; leaf margins slightly serrate to serrulate at apex |[[#key-0-4| > 4]] |-id=key-0-4 |4 |Paraphyllia few to absent; central stem leaves oblong-ovate; ecostate or costae double, short; widespread. |[[Neckera pennata|Neckera pennata]] |-id=key-0-4 |4 |Paraphyllia many; central stem leaves oblong to oblong-ligulate; costae single, 3/4 leaf length; w United States, Canada. |[[Neckera menziesii|Neckera menziesii]] |} </div></div><!-- -->{{#Taxon: name=Neckera |author=Inés Sastre-De Jesús |authority=Hedwig |rank=genus |parent rank=family |synonyms= |basionyms= |family=Neckeraceae |distribution=North America;Mexico;West Indies;Central America;South America;Europe;Asia;Pacific Islands;Australia |reference=None |publication title=Sp.
