144 Salmon.— A Monograph of 
cells wide. The leaves in drying shrink very much, and 
become slightly twisted, keeping erecto-patent and not be- 
coming appressed. 
The present species is described as ‘ monoicous ’ in ‘ Muse, 
austr.-amer./ but no description of the male inflorescence is 
given. On dissecting several fertile stems of the examples in 
s Muse. Amazon, et And., nr. 141 d,’ no trace of any male 
inflorescence could be found. Further, a specimen in Mitten’s 
herbarium shows that clavipes is really dioicous. This 
specimen bears the name of ‘ 5 . Masseei’ and is thus described 
in manuscript: 
‘Folia oblongo-ovalia patentia apice recurva acuminata nervo in 
acumen piliferum apice laeve exeunte margine recurva inferne reflexa 
apicem versus denticulis aculeiformibus e limbo cellularum angus- 
tissimarum seriebus 2-3 oriundis serrulata, cellulis in folii medio 
oblongis versus marginem abbreviatis subquadratis utriculo collapso 
[repletis] perichaetialia parum longiora ad thecae cylindraceae apicem 
vel paulo infra attingentia, pedunculus brevissimus in collem thecae 
sensim dilatatus operculum elongato-conicum, peristomium basi 
coalitum. — Loxa, on branches ; Massee to Spruce. Very like -V. 
setiferus , but with a distinct limb ; the capsule with scarcely any 
distinct seta which is not twisted.’ 
This moss is certainly 5 . clavipes , agreeing exactly with the 
examples in Spruce's ‘ Muse. Amazon, et And., nr. 141 d.' 
The specimen is of special interest from the fact that it bears 
male flowers. These are borne on what appears to be a dis- 
tinct plant, the stem of which arises out of the tomentum by 
the side of a fertile plant. The stem of the male plant is 
1 centimetre high, and is branched dichotomously at half its 
height beneath a male inflorescence ; each branch bears 
a male inflorescence at its apex, beneath which the dichoto- 
mous branching is repeated. The stem at the places where 
the branches originate produces numerous brown radicles. 
In general habit, and in the rather thick gemmiform flowers, 
the male plant of S. clavipes much resembles that of S. lati- 
folius , Mitt. (S. Lindigii , , Hpe). In the single stem that
