lamina 1-3 poUices longa, nunc longitudine sequilata, nunc angustior, 

 basi 5- V. 7-nervis, membranacea, subtus in axillis nervorum lanafioc- 

 cosa rufescente vel lutescente barbata ; serraturse triangulares vel 

 rotundatse, plus minusve approximatse, vel distantes, insequales vel 

 subsequales, mucrone brevi, cartilagineo, albido, nonnunquam apice 

 calloso mucronatse ; petioius gracilis, 6-24 lineas longus (foliorum 

 infimorum semper lamina brevior). Pedunculi plerumque folio paulo 

 longiores (semper petiolo longiores) ; bractea lanceolata, v, lanceo- 

 lato-oblonga, apice rotundata v. attenuata, flores superans pedicellisve 

 superata, nunc usque ad basin pedunculi decurrentes, vel ab ea plus 

 minusve remota ; pedicelli umbellati, v. corymbosi, v. trichotorae cy- 

 mosi, pedunculi parte libera nunc longiores, nunc breviores. Sepala 

 vix ultra 2 lineas longa, oblongo- v. ovato-lanceolata, obtusiuscula, 

 subtus glabra v. pulverulenta, supra sericeo-tomentosa. Petala 2|-3 

 lineas longa, lanceolato- v. oblongo- spathulata, obtusa, albida, apice 

 obsolete crenulata. Stamina 25-30, libera (an semper ?), petalis de- 

 mum dimidio longiora. Ovarium sericeo-tomentosum. Stylus glaber, 

 post anthesin staminibus vix superatus. Nux pisi minoris volumine, 

 tenuis, fragilis, tomento rufescente, floccoso, demum deciduo induta, 

 immatura turbinata v. pyriformis.
