Caspiies parvi, pallide olivaceo-virides. Caules sub J- unc. longi, ramis divaricatis. Folia remota, suberecta, anguste obovata, lobo inferiore extus ad inflexionem dento obtuso aucto.
The miimte size, more erect, narrow and more distant leaves, will readily distinguish this species from small states of /. serpyllifolia, even in the absence of fructification.

Laxe cellulosa. Caules per plantas alias dispersi, non csespitosi, pallide flavo-olivacei, 2-3 lin. longi, siccitate fragiles, irregulariter ramosi, ramis remotis. Folia basi semiamplexicaulia et subsaccata, superne oblonga et rotundata, apicibus plerumque reeurvis, cellulis majusculis aquosis. Stipula cauli arete appressse, inconspicuse, oblonga?, caule vix latiores. Ferichatii foliola tria, lateralibus erectis concavis obtusis lobulo acuto intus auctis, tertio v stipulari oblongo bifido stipulis omnino conforrni sed majore. Calyx apice tubulosus, demum in lacunas quatuor dehiscens. Capsula spherica, pallide brimnea, valvis basi coadunatis. Senium majuscula, pauca, angulata ; filis spira- libus paucis, diametro seminiun.
Very nearly allied to the J. ulicina, Tayl. (./. minutisshna, Brit. Jung.), preferring also wet mosses on which to grow. The British plant may be distinguished by its smaller size, the larger cells of the leaves, which are not so concave and subacute, whilst then lobulus has a sharp process or tooth at the point of involution, also by the more divided stipules, whose segments are acuter, and by the recurved perichsetial leaves.

76. Jungermannia latitans, Hook. fil. et Tayl. ; minima, caule tenuissimo prostrato ramoso, foliis remotiusculis suberectis celluloso-crenulatis ovatis acutis apicibus seepe incurvis, lobulis ovatis involutis, stipulis inconspicuis bifidis segmentis lanceolatis obtusis, foliis perichsetialibus late obovato-cuneatis acuminatis.

Cellulosa, minima. Caspites laxi, dispersi, planiuscub, pallide virescentes. Folia remotiuscula, longitudine varia, acuta v. acuminata, cellulis preecipue versus margines majusculis tumidis et prominentibus, hinc folia subcrenata, lobulo a latitudine folii. Stipula valde inconspicure, caule vix latiores. Perichatii foliola ramis anni pnece-dentis terminalia, erecta, obovata, acuminata, lateralia incurva, tertio oblongo concavo bifido.
Closely resembling the /. kamatifolia, Hook. ; but the leaves are much broader. From /. echinata, Tayl., it may be known by the presence of stipules ; from /. albo-virens, by its smaller size, more cellular texture, and acute leaves.
