METZGERIA. 551 
Flores dioici: 9 spicam perbrevem, limbo laciniato utrinque involucra- 
tam, pistillidia sub 8-juga foventem, sistentes. Calyptra magna 
clavata, prope basin 6 cellulas, apicem versus 1-2 cellulas,-crassa, 
tuberculata, desquamans. Capsula multo brevior, subcylindrico- 
oblonga, endothecii cellulis crebre columniferis. Pedicellus brevis, 
cellulis 16-seriatis (se. corticalibus 12-, axialibus 4-seriatis) constans. 
Elateres prelongi laxe unispiri, utroque fine capillacei. Spora 
minut, elateribus vix equilatie. 
Amenta ¢ pinnulis pinnaruin infimis abbreviatis constantia, alveolis 
biseriatis sub 8-jugis excavata, limbo incurvo acute plurilobulato 
involucrata. 
A. prehensilis Tayl.! (Caput Horn, Mook. fil.) statura habituque nostra
