Studies in the order piperales

V. A contribution to the study of floral morphology of some species ofPiper

  • Published:
Proceedings / Indian Academy of Sciences

Summary

The vascular anatomy of the flower in general is uniform in all the species ofPiper studied. A flower is always supplied by a single branch that gives out first a trace to the bract. The remaining vascular supply gives out traces to the stamens or staminodes when present and then supplies the gynæceum. Only in some species likeP. Tucumanum adnation of the stamen traces and in the female flowers ofP. longum of the bract trace with the carpellary dorsals, has been observed. The gynæceum supply splits up at its base into three dorsals and one ventral strand. Secondary laterals are observed only in three species. InP. longum the dorsals are seen fusing below the stigmas otherwise they directly supply them.

Embryology inP. Gaudichaudianum has been studied and it is concluded that it followsFritillaria-type as in other species ofPiper.
