Taxonomic notes on Bornean Cryptocarya R.Br. (Lauraceae)  [Page 63 - 68]
Cryptocarya is sharply defined from other genera in the Lauraceae by floral morphology and fruit development. The ovary is superior and seated within a deep and distinct hypanthium. The developing fruit remains free from the hypanthium but is completely enclosed by it. The resulting inferior fruit has two walls - an outer wall developed from the hypanthium. and an inner wall derived from the ovary wall. The only other tree genera of Lauraceae in SE Asia with inferior fruits are Eusideroxylon and Potoxylon, but in these two genera the ovaries are semi-inferior and the pericarp develops from the 'fusion' of the receptacle and the ovary wall resulting in a single fruit wall.                                                                                                In Borneo, 15 species of Cryptocarya are recognized. Seven species are reduced to synonymy.
