CRYPTOGAMIA. HEPATIC^. Jungermannia. 1089 
with two or three teeth at the end; lower ones with more teeth. Dill. 
(Barren fructification unknown: fertile, lateral upon the surculi, and fre¬ 
quently arising from the axillae of the branches. Hook. Teeth acute, 
mostly on one side the leafit. 
(An elegant var. has been observed scarcely exceeding an inch in length, 
slender, and minute. E.) 
(Sharp-toothed Jungermannia. E.) On Snowdon. Dillenius. On 
the mountains of Scotland. Dickson. On Crib y Ddescil, and Cader 
Idris. Griffith. 
J. pauciflo'ra. Shoots creeping, very much branched, thread-shaped: 
fruit-stalks lateral: leaves bowed in, deeply divided: sheaths 
conical, remote. Dicks, ii. 15. 
{E.Bot.2 482? E.)— Dicks. 5. 9. 
Leaves alternate, remote, cloven down to the base. Segments equal, strap- 
awl-shaped, bluntish, concave, transparent, in the instertices opake. 
Fructifications solitary, remote. Sheaths conical. Fruit-stalks as long 
again as the involucrum. Nearly allied to J. multiflora , and at first 
sight greatly resembling it, but differs from it in the number of its fruit- 
stalks, &c. Dicks. 
(Few-flowered Jungermannia. E.) Near Croydon, growing on Sphag¬ 
num palustre. Dickson. Yorkshire. Mr.Teesdale. (Norfolk and Suf¬ 
folk. Mr. Turner. E.) 
C. (1) Leaves winged : leafits with appendages : fruit-stalks terminal. 
J. undula'ta. (Stem erect, subdichotomous: leaves unequally two- 
lobed, waved, entire: lobes roundish, con duplicate, lower ones 
largest: fruit terminal: calyx oblong, incurved, compressed, the 
mouth truncate, entire. Hook. E.) 
{Hook. Jung. 22— E. Bot. 2251. E.)— Vaill. 19. 6— Bill. 71. 17. 
{Stems one to five inches long, mostly naked below. Leaves distichous, 
lower ones distant and small, upper ones larger and imbricated; colour 
varying from dull green to purplish: Peduncle about half an inch long. 
Calyx compressed and incurved towards the mouth which is entire and 
truncate. Grev. E.) 
(Wavy-leaved Jungermannia.) Shady places, moist rocks, and in 
small streams. E.) P. March—April. 
J. nemoro'sa. Shoots doubly winged above: leafits fringed. 
{Hook Jung. 21— E. Bot. 607— Hedw. Theor. 15— JDill. 71. 18— Mich. 5. 8 
— {Hill. 71. 19— E. Bot. 2437— J. resupinata : Jid. Hook. J. nemorosa 
var. E.) 
Leafits broad at the base, and enveloping the mid-rib, so that there appears 
no interstice between the leafits and the appendages or coloured scales 
placed above them. Weis. Plant mostly about one and a half inch long, 
branched or unbranched. Leafits oblong, numerous, green, pellucid. 
Involucrum terminating, broad; at first leaning. Dill. (The strongly 
dentato-ciliated margins of the leaves in J. nemorosa will readily distin¬ 
guish it from J. undulata; and J. umhrosa ; Hooker; who suspects our 
author to have mistaken a purple var. /3 purpurascens, f. 16. for the real 
J. purpurea of Weis, {Mnium Jungermannia. Linn. E.)
