1154. I. brachycladon, Kindb., Bryol. N. Am. & Eur. 35.

Differs from I. aplocladum: Leaves smaller; those of the stem subovate, nearly entire, with very short or indistinct costa; branchleaves sometimes short-acuminate. Stem creeping, irregularly divided; branches distant, very short,slightly curved not julaceous. Tufts bright green. Capsules unknown. Habit of I. striatum.

Dr. A. J. Grout writes on this specimen "Not aplocladon. Probably myurellum."

1155. I. hylocomioides, Kindb., Bryol. N. Am.& Eur. 35.

Differs from I. Breweri. Leaves shorter, subovate, generally subobtuse, more sharply serrate above to below the middle; apical cells oval-oblong, middle and lower linear, alar disposed on a short space. Perichetial leaves minutely denticulate. Capsule cylindric-oblong sometimes curved; teeth pale yellow; cilia short; lid not seen. Tufts loose, green or brown-green. Stem bipinnate; branches numerous not julaceous, often with short flagellae.

1156. I. thamnioides, Kindb., Bryol. N. Am. & Eur. 36.

Stem-leaves denticulate below, serrate or twice serrulate above; upper cells rhombic or rhomboidal. Branch-leaves serrate nearly all around; upper cells lanceolate-linear, middle and lower sub-linear, alar disposed on a short space. Perichetial leaves serrate. Capsule cylindric, inclined or slightly curved; lid short-acuminate; teeth yellow; cilia short appendiculate. Tufts loose, glossy green. Branches long-attenuate nearly crowded not julaceous.

1157. I. obtusatulum, Kindb., Revue Bryol.; 1895.

Stem-leaves broad-ovate, short, acuminate, acute, recurved below, serrate above; branch-leaves smaller, suboval, obtusate often obtuse; upper (sometimes also the middle) cells oval or broad-oblong, middle narrowly oblong or sublanceolate; costa reaching to 3/4 or shorter. Capsule oblong; teeth yellowish; cilia nodose, shorter; lid muticous, acute. Stem pinnate; branches generally distant, often flagelliferous. Tufts dark green.

On rocks, Parson's Mountain, near Victoria, Vancouver Island, May 17th, 1893. (Macoun.)

The whole genus needs revision as altogether too many species have been made.

(758.; I. myosuroides, Brid.

On stones and the bases of trees at Yarmouth, N.S., June 20th, 1883. (Macoun.)

(760.) I. Cardoti, Kindb.

Rhizome creeping; secondary stems pinnate, also ligneous, often curved, sometimes bearing rigid, long and at the apex branching flagella.

Stem-leaves ovate-lanceolate, subulate-acuminate, faintly denticulate below, the acumen serrate and twisted above; cells often yellowish, all long and narrow, except the basal, the alar and inner basal dark-yellow or orange, quadrate or rectangular; costa stout reaching to 2/3; branch-leaves shorter-acuminate, sharply serrate above the middle, borders often faintly reflexed to the acumen. Perigonial leaves sub-ovate, reddish at the base; costa fine and short; antheridia 3-4 Perichetial leaves nerveless, from a short, ovate base suddenly tapering to the much longer, subulate, acumen; vagina long-ciliate above. Capsule oval, horizontally patent or cernuous, teeth pale-yellow; segments rimose in the middle, prolonged into long and smooth cilia; pedicel smooth, about 1 cm. long, arcuate above. Monoecious.

This fine species differs from I. myosuroides, in the doubly larger leaves, the stout costa, the robust ligneous stem, the rigid flagella, etc.
