JUNGERMANNIA LOBULATA.
Jungermannia caule repente ramoso, foliis distichis lio-
rizontalibus ovato-rotundatis subæqualiter bilobis, lobis
conduplicatis inferioribus saccatis, stipulis rotundatis
planis emarginatis, calyce oblongo-ovato lævi trian-
gulari. (T a b . CXIX.)
H ab. In insula Staten Land dieta, prope Cape Horn. D . Menzies,
1787.
Caules vix unciam longi, flexuosi, subpinnatim ramosi, ramulis
brevibus. Folia fuscescentia, laxe imbricata, horizontalia,
disticha, subæqualiter biloba, lobis conduplicatis ovato-rotundatis,
superiorìlìus convexis integerrimis ìnferiorilus saccatis ;
substantia compacta cellulis minutis punctata. Perichætialia
duplo triplove majora, oblonga, lobulis explanatis subæqualiter
acutis. Stipulæ parvæ, rotundatæ, planæ, apice acute emarginatæ,
marginibus hic illic denticulo instructis; calj'cinæ multo
majores, oblongæ, subbifldæ. Calyx terminalis, lævis, fusco-
purpiireus, oblongo-ovatus, dorso plano facie inferiore ángulo
longitudinali prominente.
There is a peculiar slenderness and neatness about this plant,
which at first sight distinguishes it from its very near affinity the
European J . dilaiala-, and in addition to this, I may observe
another point of distinction between them, which is, that in this
species the smaller lobe is so much larger, as to be almost equal
in size to the larger one, and that the calyx is much more attenuated,
and perfectly free from tubercles.
