NTER arbores illas Indicas, quarum figuras et defcriptiones 
nobifcum communicarunt illuftriff. Rheede in Horto Malaba- 
rico et Rumphius in Herbario Amboinenfi, DiiLeni1æ Genus certe 
adeo fpeciofum fefe offert, ut ulterius et accuratius noftrum examen 
merito mereri videatur. Hujus fpeciem non nifi unicam, à Rheede 
ab Ouds Hoorn commemoratam, illuftris à Linné in Syítemate fuo 
. fexuali collocavit, ac minus jufte huc retulit Songium Rumphii, qui 
quidem, uti etiam ejus 5a7g;u5 valde diffimiles et diftinétæ funt, atque 
fic etiam tres diverfas conftituunt fpecies. Poftea, fub meis in infula 
Ceilona excurfionibus botanicis, tres alias et quidem valde ab in- 
vicem diftinétas fpecies indagare mihi contigit, fic ut fex fint, que 
fub Dilleniz pulcherrimo genere, jam militent fpecies. Has omnes, 
breviter defcriptas, novafque depiétas, non indignas fore credidi, qu 
inferantur Actis Societatis, quz non modo pro incremento Hiftoriz 
Naturalis, et imprimis Botanices, fed etiam pro ulteriori ejus refor- 
matione fedulo vigilare fibi propofuit. 
Character generis, in Generibus Plantarum Linnzi Maras vitu- 
perandus omnino non eft, licet ill, botanicus ipfe ipfam non vidiffet
