Discusión taxonómica
R. Tryon (1955) reported that S. sartorii and S. sellowii are not well separated morphologically. The principal character of piliform pubescence on leaf bases is best seen on leaves at branching points. The less imbricate leaves of S. sellowii appear to correlate with the lack of pubescence and shorter setae on leaf tips. Tryon also synonymized S. porrecta and S. hintonii, which Weatherby (1944) distinguished on the basis of minor spore characters.A
