HOYA NEW Oh There it is ! Hoya imbricata photo on Palawan Is., Philippines A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Editor: Dale Kloppenburg Volume 2 Issue I 1 January 2014 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. The following new species are presented in PDF format with ISSN number. 1. Hoya espaldoniana Kloppenburg, Siar & Cajano 2. Hoya pubicenta Kloppenburg, Mendoza & Ferreras 3. Dischidia bulacanensis Kloppenburg, Mendoza & Ferreras 4. Hoya heuschkeliana subsp. marionii Kloppenburg & Ferreras 5. Hoya mindorensis subsp. mendozae Kloppenburg & Ferreras 6.

This new species seems most similar to Hoya anncajanoae Kloppenburg & Siar in having similar leaf structure but more linear. The sepals here are ovate ciliate 0.15 cm x 0.8 cm vs. sepals 0.15 x 0.17 widest, diameter flattened smaller 1.24 cm versus 1.70 cm, the corolla is otherwise as in Hoya lucyae ; flower diameter flattened is larger and the lobes of the corona are longer 0.25 cm versus 0.15 cm, and the pollinium are shorter 0.42 mm versus 0.55 mm. Pedicel: curved, terete, glabrous, reddish colored, 2.0 cm long, 0.06 cm in diameter. Enlarged ca. 52x. Calyx: side view enlarged ca. 25x. Sepals are sub oval, apices obtuse 0.15 cm long and - 0.08 cm wide near the base. Ovaries: are columnar, glabrous 0.10 cm tall and base pair 0.07 cm wide. 3 Calyx and ovaries top view, enlarged ca. 18x, sepals are ciliate, cells scattered and relatively long, sepal surfaces are glabrous inside and out, small overlap at base, no ligules observed. Calyx attached to the flower ventral side, enlarged ca. 12x, corona revolute, glabrous ventral, apices of corolla lobes also glabrous. Cilia visible on sepal edges. Corolla: outside (ventral) surface, enlarged ca. 15x, this surface is granulate- glabrous. Sinus - sinus 0.30 cm Sinus - center 0.25 cm Sinus - apex 0.42 cm Apex - center 0.62 cm Widest 0.35 cm Corolla inside surface (dorsal) enlarged as above, this surface is pubescent except for a small apical area. Note the raised ridges from the center to the anther sinuses. 4 Corona: ventral view, surfaces are glabrous, lobes are channeled part way toward the central column which is surrounded with bilobed bulbous protrusions, anther wing apices protrude just slightly at sinuses with rounded apices. Enlarged ca. 20x. Corona dorsal view enlarged as above is bilobed with center raised, inner lobe spatulate reaching and covering the center, dorsal composed of two structures (center portion darker colored and linear convex from base of inner lobe to near outer apex; side shelved along edges, further bilobes start along the sides at the widest portion (about half way) with rounded sides nearing the outer apex and turning sideways to touch at outer apices. Back of raised darker portion of lobe center. •m. . — v Lobe side shelf begins here. . . -s. Bilobed extension inner end. Bilobed outer apex. Outer apex of the coronal lobe. Spatulate inner lobe. 5 Corona lobe ventral view, channel is open at outer apex, edges rounded and rolled under, channel open toward central column (upper left). Note the bilobed protrusions from the column base pointing outward toward the lobe groove. Enlarged ca. 27x.

Inner lobe is centrally creased below. 6 Dorsal surface of a coronal inner lobe, the surface is linearly very finely sulcate, there is a channel on the under side that in the photo above appears as a channel. Projection from upper left is the anther apex. S Coronal lobe dorsal section just out from inner apex, here a raised central (convex) portion of lobe extends to outer lobe apex, below you can see the thin ' shelf that is part of the lobe, the lobe has a granulate- sulcate surface, lighter portions (above and to left) are the beginnings of the bilobed extensions. Coronal outer dorsal apex, with bilobes extending beyond the blunt (center lighter color) outer apex. Bilobes have rounded edges and flat- cupped in inner sides, touching or nearly so at outer apices. 7 Pollinarium enlarged ca. 170x. The pellucid edge barely extends to the pollinium inner apex and not to the inner apex nor to the caudicle attachment point. The translators are surrounded with irregular ovate non- clear tissue. It appears the translators are linear but also have short perpendicular extensions, are the irregular shaped portions the caudicle or are they hidden by these structures. A very unusual and rare structural combination. Pollinium: length 0.42 mm and widest 0.18 mm widest Retinaculum: length 0.10 mm; shoulder 0.09 mm; wide, hip and waste similar extensions 0.04 mm.

In respect to the species {Hoya mindorensis Schltr. 1906) is alike in pedicels, similar in the corolla being reflexed and with the tufts of hispid hair cells on the dorsal surface, and the conduplicate lobes at the sinuses (Dr. Schlechter’s comment: This spices is very remarkable in the two auricles that exist between the corolla lobes.) and the corona being horizontal with the dorsal keeled and the same outer apex, dorsal divided keel and crease, the anther wings shaped like a sickle. It differs in not having ovate calyx lobes, having a larger corolla 1.10 cm contrastre 0.90 cm, with the anther wings not extended and the pollinaria shorter 0.50 mm contrastre 0.57 mm. It differs from the subspecies H. mindorensis subsp. superba Kloppenburg 2005, in having the coronal lobes reaching the center and being horizontal not curving downward at the outer apex, again the sepals are not ovate, the corolla is much smaller 1.10 cm in diameter versus 1.60 cm and the pollinia are shorter 0.50 mm versus 68 mm.
