HOYA NEW Oh There it is ! Hoya sp. American Samoa Palmate attenuate leaf 1 A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Volume 2 Issue 2 May 2014 Editor: Dale Kloppenburg Contents When a species is collected from the wild, I feel it is wise to identify it, propagate it and name it. In this way it will eventually get it into commercial channels, be distributed to all those interested in this genus and thus be preserved. If in the future the species is lost through natural causes or forest destruction it will still be here on earth in your collection.

This new species is much different from Eriostemma ciliata Kloppenburg & Gilding, the flower color here is pale green not nearly black and it also does not have grooved leaf petioles and the petioles, pedicels, and sepals are much more ciliate or pubescent (hirsute) and the coronal column here is very long and prominent not “very short” among the many differences. This new Eriostemma species is named in honor of the collector. Dr. Franz Seidenschwarz is a Chemist and Botanist from Munich University (LMU) in Germany. Conducted his Dissertation about pioneer vegetation in the upper Amazon basin. He worked as a consultant and professor at the University of San Carlos in Cebu City, Philippines for 21 years (1987-2008), conducted many projects in the field of biodiversity preservation and watershed management (indigenous tree program, nature park designs, survival habitats for endangered species, plant and animal inventories), he was honored as an adopted son of Cebu City on 23 April 1997. Since April 2009 he has been assigned as the German honorary counsel in Cebu City, Floral parts follow: 11 Pedicel: section enlarged ca. 12x.
