Jubulaceae ( 4 species)

Scientific NameCommon NameSummary
Frullania californicaID notes from BFNA treatment:

Has dorsal lobe ocelli that are variable in their location. While the ocelli are generally few, they may also be scattered or form a short median line in some expressions. May sometimes have dorsal lobe apices that are sporadically acute or even sometimes acuminate. These specimens are otherwise identical to specimens with rounded apices.

Distinguishing from Frullania franciscana: Ocelli sometimes scattered on the dorsal lobe (cf.

Distinguishing from Frullania nisquallensis: ventral leaf margins plane or nearly so
Frullania chilcootiensis
Frullania franciscanaID notes from BFNA treatment:

has variable dorsal lobe apices that are usually rounded, but may sometimes be bluntly acute.

Distinguishing from Frullania californiana: ocelli arranged in a median line that is 1--2, sometimes 3 cells wide for F. franciscana, versus ocelli sometimes scattered on the dorsal lobe

Distinguishing from Frullania nisquallensis: In F. nisquallensis the ocelli are frequently absent, although they may be present in a few dorsal lobes as a short, broken line. The ventral leaf margins of F. franciscana usually have a blunt angulation on one or both sides at about the middle of the leaf.
Frullania nisquallensisSmall golden to dark brown leafy liverwort found on tree trunks and less often on rock surfaces. Plants have tiny gladiator-helmet shaped lobe on the lower surface of leaves.


ID notes from BFNA treatment: has ovate dorsal lobes with acute to acuminate, deflexed apices, and ocelli absent, scattered, or forming a partial or broken median line.

In F. nisquallensis, the ventral leaf margins are entire and reflexed at or above the sinuses. By comparison, both F. franciscana and F. californica have the ventral leaf margins plane or nearly so.

PacNW herbarium database shows no collections of this species from Southeast Alaska (only from the Aleutian Islands). Possible mix-up with Plagiochila porelloides, which Worley apparently did not include (though there are several collections identified as this species which he made - habitat is different than he described for P. schoefieldiana, however)?

Orthotrichaceae ( 18 species)

Scientific NameCommon NameSummary
Lewinskya speciosaWorley's map shows collections from the northern mainland. From BFNA "The ribbed capsule, large size, and more slender leaf apices distinguish it."
Orthotrichum anomalumWorley reports this as primarily an interior species, with the only coastal record from Skagway.
Orthotrichum columbicumRecently (re)separated from Orthotrichum consimile (see paper linked below in references). Calyptra naked (separating from O. consimile) and exostome not reddish (separating from O. pulchellum)
Orthotrichum consimileRecent paper (see link below) indicates this species may occur in the region, but Orthotrichum columbicum is likely much more frequent. Hairy calyptra distinguishes this species from Orthotrichum columbicum
Orthotrichum cupulatumReported from limestone outrcrop on Kuiu Island. Has been considered rare in Alaska and BC, where it is primarily known from the interior (Worley notes)
Orthotrichum lyelliiCollections noted by Worley all from far northern mainland. Has been found on non-native landscaping trees in Sitka.
Orthotrichum obtusifoliumWorley reported as known only from Skagway.
Orthotrichum pulchellumScattered collected noted by Worley from across much of the region.

Separated from Orthotrichum consimile and Orthotrichum columbicum by reddish exostome.

From BFNA account: "Distinguished from all species of Ulota by the glabrous calyptra and immersed stomates, and from O. consimile by the 16, reddish exostome teeth that are papillose-reticulate with slender, high papillae, and by the stomates that are always located at or beyond the middle of the capsule. Also, O. pulchellum has plants that are rarely longer than 1 cm and the capsules are usually just barely exserted and oblong-cylindric."
Orthotrichum rupestreWorley reports this has been found at Lake Lindeman, BC - and has more of a continental distribution.
Ulota barclayiWorley shows collections span the region. BFNA indicates leaves should be much less twisty than other species in the area. Also leaves at base of sporophyte will be different than the rest of its leaves, and exostome teeth are reflexed.
Ulota curvifoliaWorley notes only reports are from Skagway and Lake Lindeman. Grows on rock (may be more likely to be found at higher elevations - if it occurs in the region beyond where it's been reported).
Ulota drummondiiWorley shows records from outer islands and near Juneau, and reports its generally on alder in this region. Capsule more football shaped should be distinct.
Ulota megalosporaA few collections were noted by Worley, who thought it probably occurred throughout the region. Creeping stems with erect branches should be distinct in this genus in the region (though consider Ulota reptans)
Ulota obtusiusculaCommon throughout the region. BFNA notes this species has consistently contorted and twisted leaves, even when wet.
Ulota phyllanthaCommon maritime species. Dark brown 'brood-bodies' at the end of leaves are usually present and distinctive for this species.
Ulota reptansBFNA doesn't indicate this species is currently known from NA, see http://www.efloras.org/florataxon.aspx?flora_id=50&taxon_id=250062028
Zygodon reinwardtiiWorley reports an old record from southern tip of Prince of Wales Island as the only one in the region.
Zygodon viridissimusBFNA does not include Alaska in the range of this species, though Worley indicates a handful of records from as far north as Sitka (while noting it is increasingly rare at the northern end of its range).
