IJookeria caule suberecto vage ramoso, ramis compressis,
foliis undique imbricatis ovatis obtusis minute reticu-
latis, basi binervibus, seta elongata, capsula subovata,
calyptra multifida. (Tab . XXXVIII. )
Hab. Ad npam flumiiiis Orinoco prope Esmeraldam, locis opacis,

Folia undique imbricata, albida, ovata, concava, obtusa, integerrima,
basi binervia, dorso versus apicem minute papillosa,

lacinias satis longas fissa. Peristomium Leskeæ, dentibus ext.
brevioribus.
This species will rank near Hookeria {Lesk., Hedw.) albicans.
1 he very pale, almost white, colour is common to both. Our
plant IS much larger, more straggling in its growth ; the fruitstalks
are much longer; the leaves very obtuse, entire, slightly
papillose at the back, with short nerves and a very minute reticulation.
Ill both the calyptra is multifid at the base, but the
divisions are longer in tlm ; both too are smooth, not marked
with reticulations, of which the interstices are sunk so as to form
pits or hollows, as in Hook, læte-virens and lucens.
