In Japan and adjacent areas, N. Takaki (1956) accepted 15 species within <i>Bryhnia</i>, but only six survived the revision by A. Noguchi and Z. Iwatsuki (1987+); most were synonymized with <i>B. novae-angliae</i>. Among North American species, <i>B. graminicolor</i> is not closely related to the core group and possibly should be segregated in its own genus.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Plants small; stems to 2 cm; stem leaves narrowly ovate to lanceolate, 0.6-1.1 × 0.2-0.5 mm. |[[Bryhnia graminicolor|Bryhnia graminicolor]] |-id=key-0-1 |1 |Plants medium-sized; stems 2.5-10 cm; stem leaves broadly ovate-triangular to ovate, 0.7-1.3(-1.6) × 0.7-1.2 mm |[[#key-0-2| > 2]] |-id=key-0-2 |2 |Stem leaves ovate-triangular to ovate, 1-1.3(-1.6) × 0.7-1.1 mm, longer than broad; apices acute or acuminate, rarely cucullate; stems rarely julaceous along some portions; alar regions gradually differentiated; e North America. |[[Bryhnia novae-angliae|Bryhnia novae-angliae]] |-id=key-0-2 |2 |Stem leaves broadly ovate-triangular, 0.7-1.2 × 0.8-1.2 mm, often shorter than broad; apices broadly acute to rounded-truncate and short-apiculate, often cucullate; stems julaceous; alar regions abruptly differentiated; Alaska, British Columbia. |[[Bryhnia hultenii|Bryhnia hultenii]] |} </div></div><!-- -->{{#Taxon: name=Bryhnia |author=Michael S.
