Synopsis
Excerpt from Teratology in the Flowers of Two Californian Willows
In degree of anatomical intimacy, the hermaphroditism seen in the monstrous floral organs, - where the seats of pollen-sac and ovule-production are so very close together on one phyllome. - is analogous to that bisexualism occasionally found in the common frog, where a testis may have an anterior ovarian por tion, or an ovary be anteriorly replaced by a testis.
These cases, then, of sexual abnormality among plants, like the similar instances among animals, bear upon various general questions of sex - is hermaphroditism the primitive condition in all organisms; and are male and female sex-elements, - micro Spores and macrospores, sperm and ova, - universally devel oped by differentiation of sexless cells, or, better perhaps, of cells potentially of either sex; and so on. The facts here noted may prove of interest in some such connection.

Teratology in the Flowers of Two Californian Willows (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book presents an intriguing exploration of unusual flower developments observed in two Californian Willow species, detailing how some flowers exhibit both male and female characteristics, while others show the duplication of normal sexual organs. The author posits that the existence of bisexual flowers points to the possibility that the ancestral Willow flower may have possessed both male and female reproductive structures, challenging the prevailing assumption of unisexual origins. This comprehensive work delves into various theories regarding the evolution of Willow flowers, including the idea that changes in the number of stamens may have occurred through a process of reduplication, similar to the proliferation seen in polyandrous species. The author provides evidence from monstrous bisexual organs, considering them distinct from the hermaphroditism exhibited in perfect flowers, and suggests possible reasons for the suppression of one sex in unisexual flowers. This book offers valuable insights into the evolution and development of Willow flowers, providing a significant contribution to the field of botany.
