Hey guys! I hope someone can tell me what these plants are. I live in Northern Florida and collected them at my local creek. The first plant grows to be 6 to 9 inches tall with 4 inch leaves. The second is a small leafed low growing vine.It has leaves that are 1/4 inch long,sometimes reaching 1 inch.The plant itself seems to grow quite long, longer than 18 inches,putting down roots by each leaf that touches the ground. The third is a moss that grows mostly under trees in dappled light with star shaped "leaves". Fourth is another moss with a pin point appearance. All these plants are growing in dappled light. Thanks!
Talk about a challenge! First of all, there is absolutely no way anyone could identify the mosses via a photograph. Moss identification requires details about the reproductive structures, what the moss is growing on and perhaps microscope work with the "leaves" (actually phyllids - not a true leaf). To give a story of how difficult it is to identify a moss via a photograph, I snapped a high quality photograph of a moss for the cover of an issue of the Davidsonia. The plant was displaying its reproductive structures and I knew what it was growing on - even so, some of UBC's (and also western North America's) acknowledged experts on mosses could only say "most likely it is this" without a specimen in hand and microscopy work. As for the other two, better photographs are needed, preferably "in situ" (on site) so that the shape of the plant (e.g. leaf arrangement, habit, leaf growth patterns) can give a clue of what possible plants to consider. Also, photographs of the flowers and / or fruit are highly desirable. With the photos and descriptions supplied, there are just too many "it could be"s to hazard a guess.
If the one to the top right has prickles or thorns then it could be one of the Green Briers My guess bristly Green Briar, the moss to the top left looks like polytrichum but I would check it with a list of characteristics that goes with that sp.
