Abstract

The leaf-anatomy, pollen and cytology of mature plants and seedlings of Calibanus hookeri (Lem.) Trelease have been investigated and compared with that of Nolina, Dasylirion and Agave spp. The close relationship of Calibanus to Nolina and Dasylirion, and the dissimilarity of Agave, are confirmed. Calibanus leaves have deep stomatal grooves as in Nolina; the pollen grains are elliptic and monosulcate as in all the genera examined; and the karyotype (2n = 38) is similar to that of Nolina and Dasylirion. Successful pollination with one-year old refrigerated pollen, and improved seed-germination after removal of pericarp and testa, are reported.
