CHARACTER MORPHOLOGICUS 



E COMPARATIONE 



EVOLUTIONIS ORGANORUM PER UMVERSUM RECNUM VEGETABILE OBVIAE. 



Plantae ligncsccntcs (s. xylinae), pcrenncs, loxines, i. c. ftbris ligni decussatim procurren- 



tihits instructae. Radix palaris in adu/tis nulla, radiculae plures in conicam molem compactae. 



Vaudex arborcus, teres, plerumque simplex, i.e. ramis persistentibus phyllophoris s. frondescentibus 



destitutus, rarissime ramosits. Folia c gemma nuda solitaria, rarissime, in caudice ramoso^ e mul- 



tiplicibus versus apicem conferta, vagina complete amplcxicau/ia caudieique cicatrices insculpentia, 



cxstipulata, petiolafa et laminata, completa igitur, nee vaginam nee petiolum solum exhibentia 



(quae holophylla hue ratione, ncc coelophy/la nee steleophylla nuncupavcrim). Lamina quasi 



petioli parti anticae circumcirca adnata, sursum ct deorsum p/icata intcrque plicas vario modo 



palmato- aut flabe/tato-divisa simpiiciterve fissa, divisionibus sursum ant deorsum plicatis, (indupli- 



catis aut rcduplicatis). Rami, qui adsunt, axillarcs simulquc terminates, transformati in spadices 



?. e. in ramos sexu affectos ideoque transitorios, qui loco ramulorum ultimorum phytlophororum 



f lores fcrunt, praeterea plerumque instructi foliis spathaceis s. coelophyllis (spathis) in basi 



tnquc ramificationibus. Rami hi sexuales, revcra terminates, scd succrescente coma jierennante specie 



laterales, exceptis nonnullis speciebus monocarpeis. Bractcae et bracteolae saepe binae sub- 



oppositae, saepe delitesccntes. 



Florcs symmetrici, trimeri, rcgnlarcs, verticillis iloralibus in toro parum clcvato rcgulariter 

 ahernantibus, diploperigonici, quoad inscrfioncm thalamostemoiics, inferi s. hypogyni, saepe sexus 

 diclinia (rclativa, ncc absoluta quidein) dimorplii, rarius hcrmaphroditi. Perigonium duplex: calyx 

 et corolla; utrumquc persistens, hac ratione et ob corollac structuram eoloremque plerumque quasi 

 totuin calycimnn. Calycis pars impar plerumque antica. Aestivatio valvata aut imbricata. 



Androecium duplex, rarius multiplex, singulum trimcrum (aut in indefinite polyaudris 

 intcrdum depauperatum) , rarissime simplex. Filamenta aut ima basi in toro carnosiusculo plus 

 minus connata, aut prius omnino libera, vol altius connata ideoque quasi perigyna, in aesrivatione 

 erccta. Antherae versatilcs, inter sc liberae, quadrilocellarcs, bilocnlarcs, rima dehisccntes. Pol- 

 len pulveraceum, liberum, ellipsoidcum, sublincare aut sphacricuin, sulco pcrfossum. 



Gynoecium simplex, trimerum, rarius dimerum aut simplicissimum (haplocarpicum), car- 

 pidns plerumque (sub anthesi) coadunatis, rarius distinctis. Ovulum solitarium, erectum vel ex 

 axi fructus cernuum, in fructu trimcro saepe duo abortientia. Styli perbreves indivisi, tot qnot 

 carpidia, plerumque in unum connati. Stigmata pariter simplicia, saepe connata. Fructus sim- 

 plex, tri-bi- rarissime uniloculars, aut raro triplex; drupacens vel baccatus, tri-mono-dispermus. 

 Embryo m peripheria albuminis locatus, monocotyledoneus, rostcllo centrifuge Sunt igitur

 stae ), unigeminae; spadiciflorae, spathaceae; diploperigonicae, subcalycinae (homoeo- 

 perigonicae), flore syinmetrico, triinero, regulari; e toro diplo-polyplostemones; triplo- 

 rarius diplo-aut haplocarpae, earpidiis monospermis; anospcrmae, albuminosae, embryone 

 intra periplieriam albuminis monocotyledoneo.
