1102 CRYPTOGAMIA. HEPATICiE. Anthoceros. 
(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. /3. 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 Splicer ocarpus. 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. Rot. 251— Pet. Mus. 2. 253— 
FI. 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. 
ANTHOCEROS.* 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. 47— E. Rot. 1537. E.)— Dill. 68. 1— Mich. 7.2— FI. 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 Spotted Horn-flower. E.) On 
heaths in moist shady places. Ellingham fen* Bungay* near the direc¬ 
tion 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. luE'vis. Leaf undivided* indented* smooth. 
Dill. 68. 2— (E. Rot. 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 ; Icevis the plant 
when barren, punctatus when fruiting* for the spots when highly mag¬ 
nified exhibit clusters of seeds or fertile flowers : and Dill. 68* 1 and 2* 
seem to countenance this hypothesis. 
* (From avGop, a flower ; and xeptxs, a horn : the latter word supposed by etymologists 
to refer to the ancient drinking-vessels, and thus in Homer. In the present instance the 
curled, concave leaves of the plants bear some resemblance to these cups: though, by 
another interpretation, the term might, perhaps with equal propriety, be considered de¬ 
scriptive of the erect capsules and fruit-stalks. E.)
