Here are the cones we have, male and female, that need matches. Please contact me at info@cycads.com if you have a match for any of the follwing cones: Pollen from Male Cones I have that need Female Cones to Pollinate: Cycas debaoensis (would consider interesting crosses) C. diannanensis C. taitungensis Cz. hildae Cz. kuesteriana Cz. mexicana Cz. robusta D. angustifolium D. edule “Queretaro Blue” D. merolae E. altensteinii E. arenarius (green) E. arenarius (blue-green) E. cerinus E. eugene-maraisii E. ferox E. gratus E. horridus (3 different forms) E. lehmannii E. longifolius E. natalensis E. natalensis x woodii E. ngoyanus E. schaijesii E. schmitzii E. sclavoi E. senticosus E. transvenosus E. trispinosus (including a very blue "perfect" form) E. villosus E. whitelockii E. woodii L. hopei L. peroffskyana M. johnsonnii M. macleayii S. eriopus Females Cones needing Pollen from Male Cones: E. arenarius Blue Form E. dyerianus E. nubimontanus E. princeps E. senticosus Our general philosophy is that if you send us pollen, we'll give you 50% of the seed we generate from it. Likewise, if we send you pollen, you will send us 50% of the seed you generate. We always offer to include the floaters when we send you seed, so that you know we're doing our share. Likewise, we'd hope you'll offer to send us your floaters, too. It would be great to increase the worldwide population of these species. Please email us at info@cycads.com if you have a match for any of these. Thanks.
