sevta, duplo fbliorum calycis numero uniseriata 

 8 — 10, aut abortu pauciora, rarissime qua- 

 drupla, biseriata, ovariutu cingentia, saepis- 

 sime escentrica, in floribus masculis a disco in 

 antica calycis parte luxuriante saepe in posti- 

 cam retrusa. Filamenta filiformi-subulata, 

 libera v. basi inter se coalita, saepe villosa, 

 aequalia v. iiiaequilonga. Antherae intror- 

 sae, biloculares, dorso insertae, connectivo 

 cum filamento articulato mobiles , locuiis sub- 

 oblique appositis v. sujjoppositis, intus v. latere 

 longitudinaliter dehiscentibus. 



Ovarium in floribus masculis rudimentarium 

 v. nullum , in hermaphroditis liberum, sessile 

 v. brevissime stipitatum, nunc centrale , nunc 

 disci inaequali evolutione relrusum, excen- 

 tricum, subobliquum, triloculare , rarius bi- 

 v. quadriloculare. Ovula loculorum angulo 

 centrali inserta, saepissime solitaria, adscen- 

 Oentia, rarissime suspensa, rarius geinina v. 

 interdum terna, superposita, inversa et ad- 

 scendentia, nonnunquam plurima, horizontalia. 

 Stj I ii s terminalis, simplexj stigmata lo- 

 culorum numero. 



Fructus bi- tri- quadrilocularis, v. abortu 

 unilocularis, nunc capsnlaris, lignosus, coria- 

 ceus v. niembranacens , locuticide v. septicide 

 dehisceus , valvis septiferis v. ab axi angulis 

 septante solutis , nunc samaroideus, sainaris 

 dorso, basi v. apice membranaceo-alatis , axi 

 adnatis, saepissime indehiscentibus. 



Srmina globosa v. compressa, in loculis 

 solitaria v. gemina, rarissime plura, erecta v. 

 adscendentia aut rarissime pendula, testa crus- 

 lacea v. membranacea, interdum in alam ex- 

 pansa, saepe arillata v. umbilico lato instructa. 

 Albumen nullum. 



Embryo rarissime rectus , saepe curvatus 

 v. spiraliter convolutus. Cotyledones in- 

 cumbentes, interdum transversim plicatae, non- 

 nunquam in massam carnosam coalitae. Hadi- 

 cula in convolutis extraria, saepe brevissi- 

 ma, umbilicum spectans, infera v. rarissime 

 supera. 



Sapindaceae ab ordinibus proximis non- 

 nisi plurium notarum combinatione distinguen- 

 dae, in regionibus intertropicis totius orbis, 

 copiosius tamen in America reperiuntur, in re- 

 gionibus subtropicis et temperalis hemispbae- 

 rae australis multo rariores , cis Cancrum nisi 

 in Cliina boreali vix obviae. 



Hippocastaneas olim imprimis propter folia 

 opposita palmatim composita in proprium ordi- 

 nem segregatas , vix a Sapindaceis reliquis, 

 quarum loco cis Cancrum vigent, separandas 

 putaverim , foliis in Ungnadia, genere Aesculo 

 arctissime affini, oppositis et imparipinnatis, 

 iisdem neque in Valenzuelia, genuino Sapinda- 

 cearum genere, alternis. Caeterum propriam 



inter Sapindaceas sibi tribum vindicant, a Sa- 

 pindeis ovarii loculis biovulatis, a Dodonaeeis 

 embryone haud spiraliter convoluto diversae, 

 quibus notis ad Meliosma, et ad genera Sa- 

 pindacearum anomala, quodauimodo accedunt.
