TAXI-LEJEUNEA. Pail 
Flores monoici: 9 in ramulis microphyllis, simplicibus vel pinnulatis, 
seriatim secundi quasi-laterales. Bractez foliis caulinis sat minores, 
forma varie, oblong vel ovato-lanceolatee superne plus minus 
serrate; bracteola oblonga ad + bifida pauciserrulata. 
Perianthia folio caulino breviora tubiformia vel anguste infundibuli- 
formia, inferne teretia, apice pentagona, angulis alatis, alis apice in 
cornua laciniato-ciliatove-cristata porrectis. Sectio perianthii juve- 
nilis transversa media subovalis, distincte obtuse pentagona. 
Obs. The leaves and underleaves on the fertile branchlets are only one- 
third the size of those on the stem, but of similar form, and there is only 
a single row of them below the flower on each innovation.

Pallide viridis, siccando interdum flavicans, prostrata pendulaque, tenuis 
flaccida pellucida. Caules 3-pollicares intricati subpinnati, ramis 
brevibus szepe fcemineis. 
Folia subimbricata, basi lata longitudinali inserta, semicordato-ovato- 
triangularia, rotundata vel ex obtuso apiculata, medio supero cellu- 
loso-crenulata-serrulatave, apice distincte serrulata, dentibus ine- 
qualibus sub 7, basi postica minutissime inflexa, vel non; cellule 
majuscule equilaterze vel suboblong leptodermes, basin versus sen- 
sim laxiores, marginales superiores prominule. 
Foliola foliis + breviora subimbricata, raro subdissita, cordato-orbiculata 
undulata, rim& brevissima 5 cellulas solum alta apice bidentula, 
dentibus contiguis forficatisve acutis. 
Flores monoici: Rami ¢ breves parvifolii innovando-pauciflori. Brac- 
tex foliis 1 breviores lanceolatze acute serrulate elobulat, vel altera 
parvilolobulata; bracteola obovata repanda serrulatave apice biden- 
tata, raro integra. 
Perianthia foliis caulinis vix breviora, (duplo fere longiora quam lata) 
obeonico-campanulata—rarius clavata vel subcylindrica—eplicata, 
apice dilatato corrugato-inflexa demum lacero-lobulata. Capsula 
parva globosa. ; 
Amenta ¢ ad caulem, raro etiam ad ramos, foliis obtecta iisdemque 
multo breviora, decurvo-circinata; bracteze minute 3-5-juge. 
Obs. In plagule ambitu rami arcte bipinnati parvifolii, florescentiis 
erebris, masculis precipue, onusti interdum videntur. In talibus ramis 
folia multo minora angustiora subacuminata et validius dentata sunt, 
ita ut, si non e caule typice folioso plane orta fuissent, ad speciem 
alienam pertinere viderentur.
