Ganges Hoya

Sperlingia

The following presentation of mine (via .pdf document) is an attempt to show that H. verticillata is not synonymous with Hoya acuta (H. parasitica the non homotypic specimens mentioned by Traill).

I am again trying to resolve all the material relating to the Denmark Herbarium material of Vahl's species collected evidently in 1804. For years I have been troubled by the photocopies of the images on Vahl's sheets labeled Sperlingia opposita 6:114 (1804) and Sperlingia verticillata 6:113 (1804), identified by Ruurd van Donkelaar in March 1996 as Hoya parasitica (Roxb.) Wall ex Trail. The foliage and venation of these two species are different and the venation did not appear to me to be like (H. parasitica) Hoya acuta Haworth.

Our Journey Begins

...to the fascinating world of all things Hoya.

It is my desire, always, that others use my work to further their understanding of hoya speciation. Constructive criticism is always welcome and adds to the furtherance of our knowledge. One of our weaknesses in studying Hoyas is the lack of statistical data on seedling variation. There have been a few grow-outs of selfed plants or even of plants within a cline, which would bring aid in understanding the genetics behind the variations we find in the field.

I truly hope that you find the information interesting, provocative, and stimulating -- and that you will allow Hoyas to become a beautiful part of your world. Now our journey beings...

Humble Gratitude...

As in all of my work, I owe a deep debt of gratitude to all my friends who over the years have advised me, lent a helpful hand, collected with me and for me, shared their plants and knowledge. I am most grateful for those who have sent me flowers of hoya species that they have bloomed for my microscopic studies, and without these, much of what I present here would not have been possible.

To all of these many friends I say "thank you" and that I really appreciate your help and support. I will look forward to your continued support, corrections, and additions.

My wish is that the material here will add to our understanding of this genus, and that it may become the basis of further study by those who will follow along our path of discovery.

Thank you as readers, students, contributors, and interested individuals. Enjoy the journey!
