long as the capsule. Vaginula whitish, cylindrical.  Cilie of the 
inner peristome perforate, a pair of filiform processes interposed. 
This differs from H. Megapolitanum, Bland., by the narrower leaves 
(not at all cordate,) and which are gradually (not suddenly) acu- 
minate, also by the smaller size, paler colour, and more patent 
foliage. | 
5. H. Zatifolium, Tayl. Caule procumbente, vage pinnatim ra- 
. moso; ramis brevibus, subincurvis ; foliis laxis, subcomplanatis, 
subdistichis, patentibus, late cordatis, serratis, enerviis, margine 
basi reflexo ; capsula ovata, cernua; operculo conico; seta levi. 
On soil; with Hookeria parvifolia, Tayl. Puerto del Napo. Dr. 
Manuel Villavicensio ; communicated by Prof. W. Jameson. 
Stems very slender. Shoots pale green. Leaves rather dis- 
tichous, patent, almost squarrose, their points elongated. Inner , 
peristome with sixteen minutely perforate Zacinia, having paler and — 
shorter but similarly perforate processes interposed, which, how- 
ever, sometimes divide at their apices. No male flowers observed. 
Perichatia very short. Numerous are the foreign Hypna with a 
similar aspect, and with patent, nerveless and subdistichous leaves ; 
we have seen none of the minuter species, (among which ours must 
range,) with leaves so widely cordate, or with so short a conical lid. 
6. Hypnum? Zeucotrichum, Tayl. Caule prostrato, longissimo, 
pectinato, apice simplici, elongato; ramis brevibus, patentibus, 
complanatis, incrassatis, apice arcte convolutis ; foliis lucidis, 
imbricatis, caulinis raris, adpressis, rameis erecto- patentibus, 
siccitate plicatis, rotundato-oblongis, elongate apiculatis, pili- 
feris, pilo subdenticulato, concavissimis, mediotenus tenuinerviis.

Stems one foot and a half long ; biais half an inch long, | 
closely set; but the summits of the stems, for one or two inches, 
are simple and have but a few distant leaves. The new shoots on — 
the summits of the branches, having the leaves closely comp : 
into brownish points, may be mistaken for perichetia. This bears | 
some resemblance to a variety of H. palustre, L., found on wet 
rocks in rivers in Ireland, but is easily disioi by the more 
suddenly acuminated leaves, and by their distinct though es 
nerves. No male flowers were observed. Du
