1322 L. Radlkofer. — Sapindaceae. 



crystallorum seriem foventiu m exstructum duplo triplove crassiore in speciebus pluribus 

 (P, longifoliolato et P. macrophyllo exceptis) cellulis secretoriis saepius magnis erecte 

 ellipticis vel subglobosis substantiam quandam saponino affinem et granula chloro- 

 phylli pauca gerentibus persito, foliolis inde aqua agitatis spumam efficientibus, 

 glandulis microscopicis subtilibus ^ digitiformibus vel clavatis rariusculis praesertim 

 subtus adspersa, epidermide non mucigera praesertim paginae inferioris e cellulis 

 margine subtiliter plicato-sinuatis conflata; petiolus teres, basi incrassatus, rhachis 

 supra bisulcata. Inflorescentiae axillares vel ad foliorum cicatrices singulae vel paucae 

 fasciculatae, thyrsi parvi vel paniculae mediocres, folia dimidia vix unquam aequantes, 

 interdum a basi ramosae, ramis thyrsoideis saepius elongatis divaricatis cymulas 

 stipitatas (polychasia parva vel dichasia in cincinnos abeuntia vel cincinnos) paucifloras 

 basi laxius superne densius gerentibus; bracteae bracteolaeque parvae, subulatae vel 

 lineares, puberulae. Flores longiuscule tenuiter pedicellati, parvi, 2 — 3 mm longi et 

 lati. Fructus nunc magni, Aesculi fructum aequantes, nunc minores. 



Species 8, per Asiam tropicam orientalem (Malaccam, Burmam, Indo-Ghinam) et 

 insulas asiaticas (Sumatram, Philippinas) divulgatae. 



Genus ab omnibus reliquis Cupaniearum generibus recedens foliis genuine impari-pinnatis, 

 fructus et seminis (magni, globosi, exarillati, hilo lato praediti) indole Aesculi genus in mentem 

 revocat; petalorum configuratione infundibuliformi ad genus Lepidopetalum accedit; foliolorum 

 sti'uctura lacunosa genera quaedam Nepheliearum {Otonephelium, Pseudonephelium, nee non Litchi) 

 appropinquat, insuper genus Smelophyllum cellulis secretoriis chlorophylli quoque granula foventibus.
