SYNOPSIS. 
Dr. Taylor finds this species in Ireland with calyces, of which the perichaetial leaves 
vary somewhat from our figure, tab. vin.: and I have consequently figured them in the 
supplementary plate, where it will be seen that they are divided into three or four large 
and broad, unequal, slightly toothed segments. Dr. Mohr has the subjoined observation in 
his FI. Crypt. Germ., immediately following his division of Hypnum, “ foliis diversimode 
vergentibus, binerviis v. subcnerviis.” p. 349. ” Hujus subdivisionis videtur, Jung, setacea, 
Web. Spic., ex ipsius herb., frucfu vero carens. Folia non gemina, quod auctor habet, sed 
laxius disposita, subpatentia, subulata, enervia omnino visa, integerrima. Jungermanniu 
nullo modo est. Vix unquam teneriorem speciem vidimus.” Weber's words are certainly 
at variance with this description, and are such as I think no one would hesitate in applying 
to our Jungermanma : “ Surculi sunt tenuissimi, repentes, semiunciales, unciales, into 
interdum longiores, ex albo virescentes. Folia alterna, gemina, setacea, brevia, non nisi 
lente accurate perspicienda.” Web. Spic. p. 156. 
3. J. julacea, cattle erectiusculo, vage ramoso, filiformi: foliis quadrifariis, ovatis, arete 
imbricatis, ercctis, acute bitidis, segmentis lanccolatis, acuminatis, subserratis ; peri- 
chaetialibus quadripartitis : fructu terminali; calycibus oblongis, superne plicatis; 
ore aperto, dentato. (Tab. ii.) 
J. concinnata. Wahl. Lapp. p. 384. ( excl . syn. Lightfootii.) 
From the description, no less than from the reference to the figure of J. julacea, in 
English Botany, there is no doubt but Dr. Wahlenberg has quite mistaken the J. concinnata 
of Lightfoof, calling it J. julacea, and vice versa the true J. julacea, J. concinnata : but 
why he has arranged our plant among the stipulated Jungermanniae 1 cannot conceive. 
Indeed, in order to do this, he has been under the necessity of forming a division, which 
he defines, “ Stipulis magnitudine et figurh ferb foliorum : ” this contains, besides our 
J. julacea, J. setiformis and J. tricliophylla ; on none of which have I ever seen any thing 
which can be looked upon as stipules. Even in the arctic regions, this species is confined 
to the highest mountains. “ Habitat,” says Wahlenberg, " in teriA nudk limos& irrigate 
juxta nivem perennem summarum alpium passim.” 
4. J. laxifolia, cattle erccto, simpliciusculo, filiformi: foliis distantibus, quadrifariis, erecto- 
patentibus, ovatis, subcarinatis, acute bitidis ; (perichsetialibus similibus :) fructu 
terminali ; calycibus oblongis, subplicatis ; ore coutracto, dentato. (Tab. lix.) 
5. J.juniperina cattle erecto, flexuoso, subsimplicc : foliis quadrifariis, lalcato-secundis, 
lineari-lanceolatis, bipartitis; segmentis rectis, acuminatis : fructu terminali; caly- 
cibus ovatis, foliosis, (Tab. iv.) 
I have gathered specimens of this species with male fructification, which is axillary. 
Perigonial leaves large, swollen at the base. Anthers spherical, (v. Suppl. Tab. i.) 
6- J. Hookeri, cattle erecto, subramoso : foliis undique imbricatis, ovatis v. oblongo-ovatis, 
hie illic lobatis angulatisve : fructu terminali ; calyce nullo ; calyptra magna, 
oblonga, carnosa, la;vi. (Tab. liv.)
