»Ramulis angulatis glaberrimis, foliis tenuiter coriaceis lanceolatis inte- 
gerrimis basi rotundatis apice caudato - acuminatis penninerviis opacis 
utrinque subdistincte reticulatis, 9—2!/, poll. longis, 9—11 lin. latis, petiolo 
filiformi 3-lineali, floribus . . .? samaris paucis fusco brunneis, in cymas 
terminales laxas dispositis, 45 lin. longis divergentibus, alis venosis dorso 
rectis ex apice obtuso intus sensim curvatis loculum ovoideum valde con- 
vexum nervatum triplo superantibus. 
In jugo Lo-fau-shan, prov. cantonensis, m. Sept. 1883, detexit 
E. Faser. (Herb. prop. n. 22 220.) 
Intermediate between A. reticulatum Champ. and 4. laevigatum Wall., but with the 
leaves much less closely netted than in either. In foliage it agrees most with the latter, 
in fruit with the former, except that the dorsal edge of the wing is contiguous to the 
fruit-cell, and not separated by a distinct intermediate membrane.» 
Specimina examinare non potui. 
VI. Negundo. 
Arbores dioicae ramis gracilibus, gemmarum perulis non imbricatis, 
gemmis basi petiolorum obtectis. Gemmae ramorum terminales semper 
vegetativae, nunquam flores producentes. Folia impari-pinnata, 3 —5-fo- 
liata, foliolis petiolulatis. Flores foliis multo praecociores, in inflorescentias 
semper laterales dispositi, apetali, sepalis minutis, basi unitis, disco nullo, 
Inflorescentia mascula laxa, primo statu capitato-fasciculata, deinde pedi- 
cellis capillaribus plus minus elongatis. Stamina pauca, 4—6, filamen- 
tis elongatis, connectivo ultra antherarum linearium apicem producto. 
Inflorescentia foeminea longe racemosa, pendula. Gynoeceum juvenile to- 
mentosum, mox glabrescens, stylo saepius usque ad basin partito. Fruetus 
loculi angulo acuto adscendentes, angusti, alis adultis pellucidis. 
Sectio Negundo continet tres species boreali-americanas arete affines, 
quarum una incola regionum atlanticarum, altera quasi medium tenens 
inter praecedentem et sequentem in regno mexicano lecta est; tertia in 
regionibus occidentalibus viget. 
Clavis specierum dichotoma. 
I. Fóliola adulta subtus velutino-pubescentia. 
1. Foliola irregulariter inciso-serrata ; stylus non usque ad basin 
partitus; rami juveniles densissime cinereo-pubescentes . A. californicum. 
2. Foliola regulariter dense serrata; stylus usque ad basin 
partitus; rami juveniles parcissime vel non pubescentes . . A. mexicanum. 
II. Foliola adulta subtas glabra vel pilosa.. Rami juveniles 
glaberrimi . . . . . . . . . 7... A. Negundo.
