pericarpio succulento v. tenui et fere sicco. Semen v. semina globosa, ovoidea v. 

 oblonga, testa membranacea v. tenuiter subcaruosa, rarius coriacea. Albumen copiosum' 

 farinaceum, scepiua niveum, extus hand raro induratum. Embryo minimus saccule 

 amniotico inclusus, in foveola albuminis ad extremitatem ab hilo remotam situs radicula 

 supera, cotyledonibus brevibus sfepius parum distinctis. 



Herbae, frutices v. rarissime arbores, ssepe aromaticte v/stimulantes. Systema fibro- 

 vasculare caulis, ex obs. Casim. DC, *modo (in caule lignoso Piperis) duplex, id est 

 fasciculis periphericis tubum periphericum lignosum formantibus et fasciculis in medulla 

 sparsis stepe tubum lignosum internum formantibus, semper inter se et cum periphericis 

 quoqiie node anastomosantibus ; modo (in caule annuo Peperomke) simplex, id est nunc 

 tubo pcripherico nunc fasciculis sparsis constans.' Folia alterna v. rarius opposita v 3-4 

 natim verticillata, rarissime 5-6~na, integerrima v. rarissime 3-fida, 3-oc-nervia v a basi 

 pennivenia, baud raro pellucido-punctata v. succulenta. Stipul«j dum adsint petiolo 

 adnata;, v. ad basm dilatatam amplexicaulem petioli reducti^, v. postice in unam 

 oppositifoliam connata?, v. omnino nulL^. Interdum etiam prophyllus ramuii oppositi-

 amenta dict.t=) plus minus pedunculata., ssepius simplices, terminales v. mox oppositi- 

 folia;, rarius axiUares v. plures in pcduncido communi sparse, in Lactore ad florem 1 v 

 2-5 reducUe. Flores parvi, s®pe minuti, secus rhachin sparsi v. sa^pius rhacliin undique 

 dense obtegentes, mterdum aimulatim v. spiraliter dense oc-seriati. Bracte.'e subquouue
