H ab. Strait of Magalhaens, D ’ Urville. Hermite Island, in th e woods, on steep banks by riy-ulets,
not uncommon, b u t rare iu fruit.
In fertile specimens the branches are arranged at intervals around a common axis, the lo-wer ones usually subdivided.
The peristome has some analogy to that of Lyellia, the teeth being vei-y smaE and the connecting base
remarkably thick and prominent. The calyptra is quite glabrous. ColumeUa apparently winged. In babit this
moss belongs to Pogonatum of Bruch aud Schimper, but its other characters do not comspond.
6. POLYTEICHUM squaniosum. Hook. fil. et Wils.; caule elongato squamoso fastigiato-ramoso, ramis
patentibus brevibus densis curvatis, foMs dense imbricatis erecto-patentibus lanceolato-subulatis stnctis

Caulis subspithameiis, ascendens, firmus, subflexuosus, atro-purpm-eus, maxima ex parte humo sepultus, triqueter,
superne squamis appressis luteo-fuscis scariosis nitidis in folia caubna gradatim abeuntibus vestitus, apice dendi-oideo-

subsecunda, siccitate appressa, e basi membranacea peUucida semiampIexicauU lanceolato-subulata, -i-ix ti-iUnearia,
superne lameUata, dorso carinaque scabra.
AltUougb this moss is very diflerent in aspect fi-om P. dendroides, the chai-acters seem scarcely sufficient to
distinguish it. The short straight leaves are only half as long as in that species.
