larger, plane postical lobe, which is not turgid at the base ; from
B. Carrwytoni, Jack, by its greenish sordid brown colour, presence
of gemmæ, coarser texture, and relatively larger postical lobe.
After the examination of numerous specimens of Badida
commutata, G., I have been unable to find sufficient characters to
separate it from B. Lindheryii, G.
This species was named by Dr. Gottsche after the late Prof.
S, O. Lindberg, of Helsingfors, one of the most di.stinguished
botanists of our time, and whose contributions to the knowledge
of the Hepaticæ, especially of European species, have been
numerous, original, and marked by an accuracy of observation
which commands both our respect and admiration.
By an error it was first published in Hartmann’s “ Handbok
i Soand. Flora ” as Badida Lindewbergiana ; as Lindberg was the
discoverer of the species, I have further altered tlie name from
Lindbergiana to Lindheryii.

Dioicous, cæspitose, small, pale yellowish or bright pea-green
in colour, young terminal branches darker green, the lower parts
and older stems being of a pale sordid brown colour. Stems
procumbent or erect when growing with mosses, imbricate,
frontally compressed, narrow, graceful, flexuose ; female plant
subpinnate, furcate or dichotomous, barren stems almost simple,
with few and very short branches, which are longer near the
apex; radiculose, rootlets few, arising from the underside of the
lobule, fasciculate, short, sordid white. Leaves imbricate, below
approximate, alternate, unequally bilobed, antical lobe roundishovate
or obovate, convexulous, entire, or when gemmiparous, erose;
postical lobe about one-third the size, rhomboid, subquadrate
or quadrate, obtuse or acute at the free angle, tumid at the base,
upper portion plane and appressed to the antical lobe ; cells
small, hexagonal, lumen usually filled with chlorophyllose
granules, walls moderately firm, trigones very minute or not
observable. Bracts, antical lobe oblong-obovate, postical oblong-
quadrate narrow. Perianth projecting two-thirds beyond the
bracts, oblong-ohconioal, with a tapering base, complánate, mouth
truncate, quite entire. Pistillidia 8-10. Calyptra with a long
neck, delicate, pyriform. Capsule oblong-oval, dividing to the
base into 4 oval valves. Spores subspherical, finely granulate.
Elaters bispiral, loosely twisted.
Male stems irregularly pinnate, catkins lateral, long or short,
consisting of from 8 -1 5 pairs of perigonial bracts, which are
closely imbricate, erect, tumid, bilobed; antical lobe oval,
postical shorter, roundish-oval ; antheridia oval, large, solitary.
