V On a New British Jungermannia. 



By Dr Thomas Taylor. 



iWitha Plate, Tab. XX.] 



Jungermannia microscopica. 



Foliosa, exstipulata ; caule tenuissimo, repente, vage 

 ramoso ; foliis distichis, emarginatis, rotundato-ovatis, con- 

 vexissimis, marginibus suboccurrentibus, dorso celluloso- 

 echinatis; fructu laterali ; calycibus obovatis, ore contracto, 

 subdenticulato. 



J. microscopica, Taylor in Flor. Hib. p. 59. — (Tab. XX.) 



Hab. In udis sylvaticis, septentrionem aspicientibus, super 

 muscos et Jungermannias parasitica. 



Oculis nudis vix cernenda, pallide virens, subpellucida. 

 Caules bi-trilineares, gracillimi, subflexuosi, parce ramosi, 

 hie illic fila pellucida, simplicia, brevia demittentes, quorum 

 ope plantula subjectis committitur. Folia subdistantia, nisi 

 arte explanata sint acuminata, cellulis eminentibus serraturas 

 mentientibus dorso exasperata ; perigonialia apice obtusiora, 

 in gremiis unicam aut duplicem antheram rufescentem, ova^ 

 tarn claudentibus; perichaetialia bina,calycis basi subappressa. 

 Calyx tumidus, ex angusta basi obovatus, ecostatus, cellu- 

 lis, aeque ac folia, externe echinatus, foliis duplo procerior. 

 Pedunculus pellucidus, transverse striatus, calycis longitu- 

 dini vix aequalis. Capsula rotundato-ovata, pallide brunnea, 

 apice in segmenta quatuor fissa, minime vero basin usque 

 laciniata. Fila pauca, recta, capsulse segnientorum apicibus 

 adfixa. Semina hand visa. 



At Gortagaree, in the wood on the roadside, between 

 Kenmure and Killarney, on the 29th January, 1835, I 

 found on the leaves of Hypnum loremn, this, perhaps the
