Fronds 3.5-5 ora. high, usually densely tufted, with
main, central axis and three orders of branches; main
axes 130-150 p. diara. in the lower parts; branches and
main axes giving rise to rarauli chiefly distichous "but
in part in whorls of three; the ramuli, variously branch-
ed in the lower parts of the frond, becoming less complex
and finally simple above, for the most part with ultimate
ramuli distichous, widely divaricate, and either alternate
or opposite above and below, or adaxial and abaxial; scatter-
ed promiscously throughout the frond, the basal cells of the
primary ramuli giving rise from the lower side to long, cy-
lindrical or slightly tapering filaments, variously curved,
18-20 p. diam.,with cells 4-6 times as long as the diam.;
ramuli gradually tapering to acute apices, with slightly
dolioform cells not conspicously shorter at the base; tetra-
sporangia 1-3 seriate, sessile,on the adaxial side of the
primary ramuli or at times on the larger ultimate ramuli;
carpogonia, cystocarps, and antheridia unknown; gland cells
widely distributed, usually one near the base of each order
of ramuli.

Growing on rocks in a sheltered locality in
littoral belt. Sitka, Alaska. Type, Gardner, no.

Apparently the nearest relative of Antithamnion simulans
is A. boreale f. corallina Ejell. The former is more robust
than the latter as the two species grovv on the ITorth American
coast. The former differs from the latter principally in the
presence of numerous gland cells and the long, slender, curved
branches always arising on the lower side of the geminate or
who rle d ramuli.
