 75.)_Flores monoici, ad axillas 1-3-ni. FL <? : Perianthium in alabastro globosuin membra- 

 naceum claiisum, per aiithesin valvatim 2-partitum, segmentis patcntibus latis 5-nervibus. 

 Stamina in centro floris cc (ssepius 7-12, ex A. DC. 2-20), filamentis liberis filiformibiis ; 

 antheree jam in alabastro erectse, lineares, prope basin dorsifixae. Ovarii rudimentum 0. 

 Fl. $ : Perianthium membranaceum, valde oblique hageniforme, tubo basi circa ovarium 

 globoso, fere a basi uno latere in coUum ascendens tubulosum basi constrictum apice 

 minute 2-4-dentatum producto. Staminudia 0. Ovarium tubo globoso inclusum, basi 

 prope collum perianthii affixum, stylus basilaris, e coUo perianthii exsertus, filiformis, fere 

 a basi papilloso-pilosulus ; ovulum a basi erectum, mox a stylo averse incurvum, micro- 

 pyle terminali. Nux subglobosa, perianthii tubo tenuissime membranaceo (interdum 

 adnato v. deliquescente) inclusa, coUo marccscente v. demum evanescente ; pericarpium 

 tenuiter crustaceum. Semen sessile, a basi erectum, ambitu pericarpio conforme sed valde 

 curvum sinu a latere inferiore profunde intruso hippocrepiforme v. quasi 2-lobum ; teata 

 tenuiter membraiiacea, dorso pericarpio subadhrerens, in latere inferiore seminis et intra 

 sinuni laxior ; albumen dense carnosum, semini conforme ; embryo in centro albuminis 

 pariter curvus, albumine pauUo brevior, cotyledonibus planis ellipticis sibimct applicitis, 

 radicula incumbenti-incurva a basi seminis aversa. — Herba annua, procumbens, ramosa, 

 camosula. Folia inferiora opposita, superiora defectu unius cujusve paris alterna, breviter 

 petiolata, ovata, integei-rima, succulcnta ; stipulfe liberie. Florum cymulpe sessiles, foHo 

 opposite^ (ad axiUam folii oppositi abortientis). Flores ^ 2-3-ni, subsessiles, ebracteolati, 

 mox caduci, ? ex eodem v. di verso nodo 1-3-ni, v. in axiUis gemini, pediceUis brevibus 

 obconicis post anthesin calloso-incrassatis fulti, bracteolis 2 stipati, sub anthesin mmuti.

Genus olini ob stationem s*pe maritimam et habitum caruosulum aenvpodiacct^ adscnptum, 

 sed fiorum et prsecipue seminum stmctura longe distat, a nonnullis pro ordine proprio habetur. In 

 omnibus tamen cum tribu Urticeannn convenit, exceptis staminibus indefimtis erectisquo quae 

 prseterea in sola Ampelocera e tribu Celiidcarum observantur, et embryone curvo, in tnbu Ulti- 

 dcarum constante, in Morels minus frequente, in Urficeis nondum note.
