Sect. XIII. Phygoptilon Radlk. 11. cc. — Capsula, junior certe, trialata, denique 

 interdum alis evanidis trigona, elliptico-lanceolata, obovata vel suborbicularis, vix 

 brevissime stipitata (cf.. Fig. 5), glabra vel tomentosa, valvis interdum juxta 

 margines tuberculatis, cristatis, vel in alulas corniformes produetis, mesocarpio 

 parenehymatico, endocarpii sclerenchymate alas ingrediente et fere usque ad mar- 

 ginem percurrente, denique (seminum incremento) plus minus bipartito, alis inde 

 plus minus evanescentibus et ad loculorum parietes dorsales augendas consumtis, 

 valvis in hac parte epithelio destitutis, juxta margines septisque tomentellis; semina 

 e trigono breviter ellipsoidea, glabra, arillo dorso fisso usque ad medium obteeta; 

 embryo oleosus, rarissime oleoso-farinosus, cotyledonibus plerumque minus crassis 

 et (ut illae Serjaniarum) plicato-curvatis; flores plerumque parvi, alabastris saepius 

 trigonis, sepalis subcoriaeeis, saepius margine tantum puberulis, 3. et 5. fere usque 

 ad apicem connatis; thyrsi solitarii vel paniculatim congesti;' corpus lignosum sim- 

 plex; folia in 1 specie (P. coriacea) ternata, in paucis biternata (P. Plumieri, revoluta, 

 cristata, trigonia), in pluribus pinnata vel subbipinnata, in 1 tandem (P. thalictrifolia) 

 supradecomposita, petiolo nudo, rhachi saepius subalata; stipulae plerumque 

 minutae; foliola glandulis malleoliformibus ornata; epidermis in plurimis mucigera, 

 in 3 (P. revoluta, rhomboidea, uloptera) non mucigera. (Species 1 — P. Plumieri — 

 antillana, 1 — P. dasygonia — guianensis, reliquae brasilienses.) 

 A. Flores majusculi; alabastra ellipsoidea; sepala omnia 



dense adpresse tomentosa; Capsula pubescens; folia 



membranacea.
