(DWARF Blasia. JUNGERMANNIA BLASIA. Three illustrative plates,

and a very ingenious dissertation, are bestowed upon this little plant, by Dr. Hooker, to prove that it does not properly belong to the genus to which authors have hitherto referred it, but rather to Jungermannia. E.) On the sides of ditches and rivers in a sandy soil. At the breaking of Medlock River Bank at Feasington Wood between Garret and Knotmill, about a mile from Manchester. Harrison, in Dill. 238. Near Halifax. Bolton. On Hounslow Heath. Hudson. (and on Shotoverhill, April, 1821, in full fructification, by Mr. Baxter, though rarely

found in that state in so southern a station. Purton. E.) P. Aug.-Nov. RICCIA.* Capsules sessile, globular, one-celled, attached to

the apex of the leaf, and containing from twenty to thirty

seeds. See vol. i. pp. 352 and 371. R. NA’TANS. Leaves inversely heart-shaped: fringed.

E. Bot. 252-Dil. 78. 18. The edges of the leaves are not really fringed, but assume that appearance

in consequence of their sending out fibrous roots. Web. About half an inch long. Fringe sometimes white. Schol. Leaves sometimes only inversely, egg-shaped, and without any notch at the end; entire at the edge, bright green. Web. Very nearly allied to Targionia hypophylla.

Huds. (Floating Riccia. E.) Pools about Hadley, Suffolk. Buddle, in Dill.

537. Sawston Moor, Cambridgeshire. Mr. Relhan. A. Aug.-Oct. R. MIN'IMA. Leaves smooth, deeply divided : acute. Dill. 78. 11-Mich. 57. 6, magnified-Schmid. 45. 3, ends of the segments

blunt. Shoots hardly a line in breadth, generally forked, entire and pointed, or else

notched at the end. In the substance and towards the base of the leaf, in the month of October we may observe greenish globules, changing to

brown and then to black. Web. (Identified with the following in Musc. Brit. E.) (LEAST Riccia. E.) On Blackheath, near Greenwich. Dillenius. In places that have been overflowed. Hudson.

A. Nov.-Dec. R. GLAU'CA. Leaves smooth, channelled, two-lobed, blunt. Schmid 44. 1—Hedw. Theor. 29. 165 to 174—(Purt. 5E. Bot. 2546. E.)

Vaill. 19. 1-Fl. Dan. 898. 1-Mich. 57. 4-Dill. 78. 10-Buxb. ii. 5. 5. I have frequently observed black spots immersed in the substance of the leaves, which are what Micheli has described as capsules full of seeds, and which has been since clearly ascertained by Hedwig. Woodw. Leaves small, the under side firmly fixed to the ground, adhering at the base to each other, deeply divided, Pol. whitish green, thick, slippery, very smooth, broadish, furrowed on the upper side, frequently forked; segments blunt. Web. Growing in a circular form. Leaves thick, issuing from a centre, often cloven. Roots fine black fibres from the under surface of the plant which floats on the water. Ray. I have never seen it on the water, but in roads and wet corn-fields both in spring and autumn. Dill.

* (A name conferred by Micheli, in honour of Signor Ricci, an Italian knight. E.)

(With the above-described species, under the name R. crystallina, Drs.

Hooker and Taylor include Var. a. Frond fleshy, glaucous, channelled, segments acute. R. glauca,

and R. minima. Linn. Var. B. Frond thin, nearly plane, yellowish green, segments obtuse.

R. crystallina. Linn. Depending on age and place of growth: the first var. growing on banks in dry and exposed situations: the latter in moist

spots, as the mould of garden pots in the greenhouse and stove. E.) (Glaucous Riccia. E.) Sandy moist heaths. In the same situations,

and usually growing with Targionia Sphærocarpus. Mr. Woodward. In clover stubbles near Bungay, Suffolk, frequently. Mr. Stone.

A. Oct.-April. R. FLU'ITANS. Leaves forked, strap-thread-shaped. Vaill. 19. 3-Dill. 74. 47-Mich. 4. 6-E. Bot. 251Pet. Mus. 2. 253–

Fl. Dan. 275. Not having seen its fructifications, it is still a doubt whether it really

belongs to this genus. Linn. Floating in stagnant water ; brown green

in spring, pure green in summer. Dill. (FORKED-LEAVED Riccia. E.) Ditches and sides of pools. P.Jan.-Dec. ANTHOʻCEROS.* Capsule awl-shaped, two-valved: Seeds

fixed to the partition or to the valves. See vol. i. pp.

352 and 3170. A. PUNCTA’TUS. Leaf curled, indented, jagged, dotted.

(Schmid. 47E. Bot. 1537. E.)-Dill. 68. 1-Mich. 7.2-Fl. Dan. 396. Capsules and fruit-stalks from one to three inches long, spreading wide in

shady places. Leaves short, scolloped, jagged, thin, pellucid, deep green. Fruit-stalks green, numerous, sheathed at the base. The whole plant turns black when dried in paper. Dill. Leaves deep green, crisp, resem, bling Jungermannia pinguis. Fruit-stalks simple, issuing out of a lopped sheathing involucrum. Capsules at the end of the fruit-stalk; valves two, bursting. Seeds adhering to a columnar receptacle. Woodw. Dots

on the leaves black. Web. (JAGGED-LEAVED ANTHOCEROS, or SrotTED HORN-FLOWER. E.) On

heaths in moist shady places. Ellingham fen, Bungay, near the direction post. Mr. Stone. Brome, Norfolk, on the borders between the high and boggy ground. Woodward. (In a stubble field at Kinwarton, Warwickshire. Mr. Purton. E.)

P. Aug.--April. (A. LEVIS. Leaf undivided, indented, smooth.

Dill. 68. 2–(E. Bot. 1538. E.) When recent, of a rich velvety green colour; the texture most beautiful

when held to the light, but without spots, Stackh. who thinks this and A. punctatus may probably be one and the same species; lævis the plant when barren, punctatus when fruiting, for the spots when highly magnified exhibit clusters of seeds or fertile flowers; and Dill. 68, 1 and 2 seem to countenance this hypothesis.

(From arbos, a flower ; and xepas, a horn: the latter word supposed by etyniologists to refer to the ancient drinking-vessels, and thus in Homer. In the present instance the curled, cuncare leares of the plants bear some resemblance to these cups: though, by another interpretation, the term night, perhaps with equal propriety, be considered de scriptive of the erect capsules and fruit-stalks. E.)

(These suggestions of Mr. Stackhouse are in some degree corroborated by

the researches of Drs. Hooker and Taylor. E.) (BROAD-LEATED ANTHOCEROS. A. major. E. Bot. First discovered in

Britain by Mr. Stackhouse, in a shady over-hanging cavity in Fowey Harbour.' Upon a tomb-stone on the north side of Arrow Church, Warwickshire: and on a ditch bank in a wet lane, near to Llanvayer Rectory,

Monmouthshire. Mr. Purton. E.) A. MULTIF IDCS. Leaf with doubly winged clefts: segments strapshaped.

Dill. 68. 4. Dillenius had not discorered this plant, but figured it from specimens sent

by Haller. I am indebted to Mr. Dickson for specimens. Resembles

Riccia fluitans, but the segments are pointed, not lopped at the end. (WING-CLEFT ANTHOCEROS. Respecting this production, so imperfectly

understood, the authors of Musc. Brit. state: * Whether we consider the descriptions of Dickson and Dillenius, or the figure of the latter, we have little hesitation in supposing that plant to be Jungermannia multifida" E.)
