Comparative pollination biology of Venezuelan columnar cacti and the role of nectar-feeding bats in their sexual reproduction.
Nassar J, Ramirez N, Linares O. Nassar J, et al. Am J Bot. 1997 Jul;84(7):918. Am J Bot. 1997. PMID: 21708646 Free article.
Additional information on the floral biology of a fifth species, Pilosocereus lanuginosus, was also included. All species showed the typical traits that characterize the pollination syndrome of chiropterophily. All species but Pilosocereus moritzianus were ob …

Population genetic structure of Venezuelan chiropterophilous columnar cacti (Cactaceae).
Nassar JM, Hamrick JL, Fleming TH. Nassar JM, et al. Am J Bot. 2003 Nov;90(11):1628-37. doi: 10.3732/ajb.90.11.1628. Am J Bot. 2003. PMID: 21653338 Free article.
We conducted allozyme surveys of three Venezuelan self-incompatible chiropterophilous columnar cacti: two diploid species, Stenocereus griseus and Cereus repandus, and one tetraploid, Pilosocereus lanuginosus. The three cacti are pollinated by bats, and both bats an …
