Notes on the Floral Biology, Cytology, and Embryology of Campynemanthe (Liliales: Campynemataceae)

Field observations of the endemic New Caledonian genus Campynemanthe (Liliales: Campynemataceae) indicate that at least C. neocaledonica and C. viridiflora are strongly protandrous and have an unusual postanthesis recurving of the filaments. A chromosome number of n = 11 has been determined for both...

Description
Summary:Field observations of the endemic New Caledonian genus Campynemanthe (Liliales: Campynemataceae) indicate that at least C. neocaledonica and C. viridiflora are strongly protandrous and have an unusual postanthesis recurving of the filaments. A chromosome number of n = 11 has been determined for both species from meiosis in pollen mother cells, these being first records for the genus and family. Endosperm formation in C. neocaledonica is nuclear rather than helobial as in several genera of the putatively related Melanthiaceae.
