HOYA NEW Oh There it is ! A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Editor: Dale Kloppenburg 1 Volume I Issue I Nov. 2013 Contents This first issue will be devoted to the publication of some new hoya species from the Philippines. I have accumulated a backlog of unpublished species and feel it necessary to publish these species namely in the name of conservation. 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. The following new species are presented in PDF format with ISSN number. 1. Hoya marvinii Kloppenburg, Mendoza & Ferreras 2013 2. Hoya unica Kloppenburg, Mendoza & Ferreras 2013 3. Hoya cupula Kloppenburg, Mendoza & Ferreras 2013 4. Hoya acanthominima Kloppenburg, Mendoza & Ferreras 2013 5. Hoya salmonea subsp. pallida Klopp., Mendoza & Ferreras 2013 6. Hoya nakarensis Kloppenburg, Mendoza & Ferreras 2013 NOTE: please see the Website publication of these species at “www.rare- hoyas.com”.

This new speeies is similar to Hoya brittonii Kloppenburg but different. The pedieels are longer with a wider diameter 0.50 -1.4 em versus 1.0 - 0.05 em, and the ealyx lobes are different, also longer and wider 0.12 em x 0.09 em versus 0.08 em x 0.08 em; the eorolla diameter flattened is larger 0.92 em versus 0.70 em; the lobes of the eorona are longer 0.21 em versus 0.1 1 em. * Hoya brittonii is listed in IPPN as unresolved, for reasons I do not know nor understand. The speeies was eolleeted by B. B. Britton at Badoe, Calapan, Mindoro Cr., Mindoro, Philippines 5 May 1953. The type sheet #19519, PNH was labeled by someone else as Hoya gracilis Sehltr., that speeies is from the Celebes and is a bilobed speeies Hoya Seetion Aeanthostemma whereas the speeies on the sheet has a eoronal skirt so is in the Hoya Otostemma Seetion.

This new speeies is in the Seetion Otostemma (Blume) Miquel, having a skirt as part of the eorona, There are only around 20 speeies in this seetion the majority being found in the Philippines. There is only two other speeies with a eoronal length (Apex -apex) that measures 0.17 em long and they are Hoya pseudoleytensis and Hoya microphylla Sehleehter 1913. There is no other published hoya speeies with a pollinia that is 26 em long and 0.10 em at the widest. There are some other unusual eharaeters about this speeies as noted below the apiees of the ovaries are unusual (granulated lip like eireular ends), there are only a few speeies where the eorona is sunken into the eorolla and also with a pentagonal thiekening on the eorolla dorsal surfaee extending from sinus to sinus. Finally there are only a few speeies with dimorphie foliage, here most are elliptie with euneate bases and aeuminate apiees but also a few small rather round leaves with obtuse bases and aeute apiees.

Sinus - sinus 0.18 em Sinus - eenter 0.18 em Sinus - apex 0.23 em Apex - eenter 0.34 em Widest 0.22 em Corolla dorsal surfaee enlarged as above, this surfaee is very densely puberulous exeept the very lobe apiees and less under the eorona (eenter area). At anthesis it is rotate with the lobe edges and the apiees are turned under. Corona is sunken into flower eenter. Corona: ventral view enlarged ea. 40x. The surfaees are glabrous, lobes are ehanneled, sides are diagonally suleate, ehannel begins slightly inward from the outer apex leaving a triangular or dimple like area. The lobes do not reaeh the eentral 0.05 em long eentral thin walled eolumn that has relatively thiek sides, surrounding area is smooth. 35 Dorsal surface of the corona enlarged as above, lobes are shallow boat shaped. Inner lobes are short spatulate keeled, dorsal is concave with a forward umbo, edges are rounded, outer apex obtuse and thin where channel below begins inward. Anther wing apices are acute.

Coronal seale side view. The seale surface out from inner lobe is suleate, here the anther (right) is bent down below the inner lobe apex, seale is relatively thiek.
