|discussion=<p><i>Ptychostomum subneodamense</i> is a distinctive species that can only be confused with <i>P. cyclophyllum</i> and <i>P. neodamense</i>. Diagnostic characters include very distant, strongly shrunken leaves when dry, a rather narrow reddish leaf base, and 1-stratose border. When leaves are stripped off the stem, a long strip of the stem often remains attached to the leaf base. <i>Ptychostomum cyclophyllum</i> has broadly ovate to orbicular green leaves with very long proximal laminal cells, base not red, and 2-stratose margins; whereas <i>P. neodamense</i> has much more crowded leaves with a fairly broad attachment to the stem, but is otherwise similar.</p>
