F. pennsylvanicae formae hortenses (varietates sec. Dippel 1. c. 77) in hortis 

 sequentes oecurrunt: 



f. nana Dippel, Laubholzk. I. (1889) 77. — Arbuscula foliis minutis. 



f. Boscii Dippel, Laubholzk. I. (1889) 77. — Rami pulverulento-tomentosi. 



Nota 1. F. profunda Bush tantum varietatem F. pennsylvanicae fructibus majoribus 

 praeditam sistit. Etiam F. lanceolata in civitate Missouri varietatem raacrocarpam habet. 



Nota 2. Formae hortenses ovata Dippel, glauca, ovalis hört., eoriaeea Dippel, longifolia 

 Dippel, fortasse magis habitu quam notis certioribus a typo differunt. Formae hortenses foliis 

 variegatis e F. pennsylvaniea X lanceolata exoriuntur.

 attenuata, breviter acuminata, superiora breviter, inferiora longius petiolulata, petiolulo 

 1 cm fere attingente pubescente instrueta, supra glabrescentia, subtus pubescentia, margine 

 indistinete denticulata. Inflorescentia circiter 1 cm longa, pubescens, satis densa. Fructus 

 late spathulatus, e basi angusta latialata, apice late euneata, obtusa vel subacuta, ca. 

 3,5 cm longus, 1 cm latus, calyce crateriformi, irregulariter dissecto, pubescente instruetus.
