Two New Trifoliolate-Leaved Species of Cucurbitaceae (Cucurbiteae) from Central and South America

  title={Two New Trifoliolate-Leaved Species of Cucurbitaceae (Cucurbiteae) from Central and South America},
  author={Michael H. Grayum},
Abstract Two new species of Cucurbitaceae, tribe Cucurbiteae, with trifoliolate leaves are described from Costa Rica, one each in Cayaponia Silva Manso and Cionosicys Grisebach. Cayaponia hammelii Grayum, with large, pendent staminate flowers, ranges from Costa Rica to Pacific Ecuador, while the exceptionally large-fruited Cionosicys guabubu Grayum & J. A. González is restricted to Nicaragua, Costa Rica, and central Panama. Both of these new species have sometimes been misidentified as… 
The evolution of Cayaponia (Cucurbitaceae): Repeated shifts from bat to bee pollination and long-distance dispersal to Africa 2-5 million years ago.
Cayaponia provides the first example of evolutionary transitions from bat to bee pollination as well as another instance of transoceanic dispersal from the New World to Africa.

Four new species ofCayaponia are described and illustrated: three from Brazil (C. cogniauxiana, C. nitida andC. rugosa) and one from Brazil and Bolivia (C. ferruginea).
Further notes on Cucurbitaceae: IV* Some New-World taxa
The New-World Cucurbitaceae badly need a thorough taxonomic revision along 'Flora Neotropica' lines, and the present paper is hardly more than a stop-gap pending the undertaking of such an account, but may be found of value to workers on the crop plants in the family as indicating the taxa most closely allied to the cultivated species.
Further Notes on Cucurbitaceae: II*
These notes are merely preliminary to a much-needed revision of this almost entirely New World tribe, which is here delimited in the sense of Jeffrey (1964). Of the genera listed by Jeffrey (1962,
Gourds afloat: a dated phylogeny reveals an Asian origin of the gourd family (Cucurbitaceae) and numerous oversea dispersal events
The history of Cucurbitaceae is addressed, using a multigene phylogeny for 114 of the 115 genera and 25 per cent of the 960 species, and an Asian origin in the Late Cretaceous is revealed followed by the repeated spread of lineages into the African, American and Australian continents via transoceanic long-distance dispersal (LDD).
