--><p>Section Niphotrichum is best characterized by fairly short costae that usually extend to 1/2–3/4 of the way up the leaf and often imperceptibly merge with the laminal cells. This results in the shape of the distal parts of the leaves, which are broadly canaliculate to obtusely carinate in profile as clearly seen in transverse sections. In addition, the costae are distinctly branched or forked at the apex in most leaves.</p>
