Cool achlrophyllous mycoheterotroph coming up on the main road near the turn off to the Los Arroyos guard shack (these bases occurred every 15-20 km or so). In fruit, no flower. No doubt a healthy mycorrhizal community in this pine duff/soil

Somehow I overlooked or got waylaid and did not take a habit view of this very slender arborescent shrub, erect, 3 m tall; lvs. not yet mature, w/ 30--33 teeth/side, glabrate; racemes loose, nodding; sepals tomentose (looks like they might be on the way to becoming glabrate); summit of ovary tomentose.

Balsam fir-Canadian hemlock-white-cedar conifer swamp, W side of creek S of Kluck Rd.

Not that anyone would be able to locate this, but I'm not going to put an exact location for this plant because of the extreme rarity in S. Florida. I believe this individual as since been extirpated due to tree fall. This was the second individual known from ENP. See Rare Plants of the Everglades (Gann et al.) for more info.

Visual Description: Gametophyte was dark green and about 1/4 inch wide. Sporophytes were green and about 1 inch in height. Spores were dark brown / black.

Habitat: Found growing next to a freshwater pond. Location was disturbed with infrequent mowing. It has a world wide distribution that includes Florida. Full distribution here: http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:30040623-2#distribution-map
