According to H. A. Crum and L. E. Anderson (1981), the columella is persistent and exserted after dehiscence. Both species in the flora area may have hyaline decurrencies only one or two cells wide descending from the alar region. Climacium japonicum Kindberg is known from eastern Asia.</p><!-- --><p>Plants in Climacium show strong phenotypic variability; in drier habitats the erect secondary stems are shorter and branches more tightly crowded (A. J. E. Smith 2004); with increasing wetness the stipe is more elongate and the distal secondary stems are more frondose. Variation between specimens of Climacium occurs also in thinness and angularity of cell walls and strength of red coloration near the leaf insertion and adjacent to the costa; these traits are probably associated with habitat shade and degree of moisture.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Branch leaf medial laminal cells (6-)7-13:1; stem leaf apices obtuse, often abruptly apiculate; branch leaf bases not or somewhat auriculate, apices obtuse; stem leaf laminal cells near insertion with walls thin, not porose; capsules shortly oblong-cylindric, 1.5-3(-4) mm. |[[Climacium dendroides|Climacium dendroides]] |-id=key-0-1 |1 |Branch leaf medial laminal cells (2-)3-5(-7):1; stem leaf apices broadly to sharply acute, sometimes apiculate; branch leaf bases sharply flexuose-auriculate, apices acute; stem leaf laminal cells near insertion with walls thick, porose; capsules long-cylindric, 3.5-6 mm. |[[Climacium americanum|Climacium americanum]] |} </div></div><!-- -->{{#Taxon: name=Climacium |authority=F.
