Euchorium, Exothea. 1411 



granulata, cellulis secretoriis sparsim et minutim (saepe obsolete) pellucido-punctata, 

 epidermide valde mueigera, contrita aqua agitata spumam sat copiosam efficientia. 

 Thyrsi paniculiformes, laxiflori, folia dimidia aequantes vel superantes, longius pedun- 

 culati, apice dichasia 3-flora vel ad flores singulos reducta gerentes, bracteis parvis 

 subulatis puberulis; pediqelli filiformes, mediocres, obsolete 1 — 2-bracteolati, ad tertiam 

 inferiorem partem articulati, circa articulationes breviter albido-pubescentes, ceterum 

 laxe pulverulento-puberuli. Flores viridule albidi. 



Species 1, cubeiisis. 



Genus — quantum ex habitu et floris indole, etsi fructus desunt, concludi potest — quasi 

 intermedium inter genera Hypelate et Exothea quorum illud inter alia differt foliis 3-foliolatis, alterum 

 germine 2-loculari. Insigne est substantia saponino, ut videtur, affini peculiari in ramorum cortice, 

 petiolis, nervoque foliolorum mediano obvia, ulterius inquirenda. 



Obs. Nomen Euchorium {ev, bene, et xÖQior, corium, cutis) a cl. Ekman propositum, cum 

 folia exsiccata ad novellorum evolutionem quasi cute (cortice) tenaci adhuc retineantur. 



E. cubense Ekm. et Radlk. — Gharacter ut supra. 



Arbor circ. 5 m alta. Rami florigeri 2 — 3 mm crassi, internodiis 2 — 6 mm, vix 

 unquam 1cm longis, glabri. Folia petiolo 2 — 4 cm longo adjecto 10 — 16 cm longa, 

 8 — 12 cm lata, interjugis circ. 2 cm longis; foliola cum petiolulis 4 — 6 mm longis ad 

 6 cm longa, ad 3 cm lata. Thyrsi plerumque 4— 6 cm, rarius 8 — 10 cm longi, apice 

 circ. 2 cm lati. Pedicelli 4 — 8 mm longi. Flores aperti diametro 1 cm.
