Within the Anomodontaceae, Anomodon is distinguished from the only other genus, Herpetineuron, by the shape and other features of the leaves. In Herpetineuron, leaves gradually taper to a point and the cells are smooth, without papillae. Three other species of Anomodon occur in Florida. A. tristis appears to form thinner mats, occurs higher up on tree trunks, and is found only in the northern part of the state. A. attenuatus forms denser mats, with more frequently branched stems that lay more-or-less flat, and taper at the ends with increasingly smaller leaves. In A. rostratus, leaves are long and taper to a fine, hair-like point.
|Leaves of Anomodon minor are elongate, tongue-shaped and with a rounded|
tip with small hard point. Cells are tiny, roundish and equipped with papillae.
Lighter streak in the center is the midrib.
Dear Associate Profesor Emeritus Frederick, as far as I know, Herpetineuron does not belong to Anomodontaceae anymore, but it belongs to Thuidiaceae. Cmiiw.ReplyDelete
Actually, there seems to be some uncertainty about this. The Plant List indeed includes Herpetineuron in the Thuidiaceae, but Flora North America, which I based my report on, included it in the Anomodontaceae. The families of mosses are in a fluid state and there have been many switches in recent years. I'm not sure what the latest expert opinion is. Do you know a more recent reference?ReplyDelete
I was curious about this uncertainty. After comenting your blog, I tried to find the recent literature. Eventually, I got the answer from SEABAL (Souetheast Asia Bryophytes and Lichens), they said that Herpetineuron is the member of Anomodontace based on the latest classification of the bryophyta (Goffinet B. & W.R. Buck,2018). This is because it's paraphyllia are not developed as well as the member of the Thuidiaceae. (furthermore: https://bryology.uconn.edu/classification/)ReplyDelete
