H O YA NEW Hoya archboldiana C. Norman 1937 Photo by Monina Siar, UPLB Los Banos, Philippines Oh There it is ! 1 A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Volume 8 Issue 1 June 2018 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. The following new species are presented in PDF format with ISSN number. Check posting on my website “http//.hoyardk.wix.com/Kloppenburg” under publications. 1.

This sp. was collected by Glen Spence 19, March 1977 from Mt. Avila, Tutuila, American Samoa, elevation 1000 ‘. In elevation this species is similar to Hoya betchei (Schltr.) Whistler but very different in many respects. Here the leaver are more broad, not as linear with a much more rounder base. Sepals are linear & ciliate and much longer relative to the corolla. The coronal lobes are here more linear and longer, with narrower inner lobes. See details below for more precise measurements. View of the corolla back with calyx and pedicel showing enlarged about 16x. This is a white cup-shaped flower rather deeply cut vs. Dr. Schlechter's drawing of H. betchei on his holotype sheer (B). Sepals is very small only 1/3 way to the corolla sinuses. Pedicel, calyx with ovaries enlarged about 16x. Pedicels are long and slim 3.0 cm. long 0.11 cm. in diameter, creamy-yellow- white, glabrous, terete. Calyx is small, outside granulose, inside smooth shiny, centrally thickened, edges ciliate. Top view of the calyx with ovaries enlarged about 16x. The sepals are small, linear to somewhat triangular, apex - base 0.21 cm., apex - center 0.29 cm. and widest 0.13 cm. Edges ciliate and membranous centrally thickened. Ovaries 0.17 cm. tall 0.11 cm. wide ate base pair. 7 Inside view of the corolla enlarged about 16x. This surface is pubescent decreasing toward the center, puberulous under the corona. Center with stellate hair cells pointing centrally. Sinuses somewhat conduplicate.

Retinacula plainly visible. Tower sides of lobes shelved and these reach the outer apex. Bottom view of the corona enlarged about 16x. The lobes are channeled with sides diagonally sulcate. Center column is thickened. Scale outer apex obtuse. Anther wing ends narrowly blunt. 8 Side view of a scale enlarged about 32x. Inner lobe is sharply raised, Anthers exceed the inner apex. Outer apex is blunt obtuse and indented. Anther wings are not deeply scythe shaped. All surfaces are glabrous. 9 Pollinarium enlarged about 165x. The pollinia are long and narrow, translator arms short triangular. The arms and caudicle seem to enter the retinaculum near its waist. Pollinia length 0.72 mm. widest 0.24 mm.

Roll 89 Hoya linapauliana Kloppenburg, sp. nova, holotypus 19258 (CAHUP) hie designatus. Similis Hoya odorata Schlechter sed differt: pedicillis 1.9 cm longis vs. 2.0 cm , et calycis segmentis triangularibus, apicie acutis etium margine sparsium ciliates et 0.16 cm longis vs. lanceolato-oblongis obtusis, margine sparsim ciliatis, 0.2 cm longis; et corolla 1.8 cm diamentiente vs. 1.7 cm. Coronie lobus non horizontalibus sed et erexit centrum, et 0.6 cm longis vs. 0.4 cm differt. Pollinara quanto alia. See below. Schlechter’s Type sheet with drawing at end. Initially it would appear that this sp. would be a subspecies of Hoya odorata, however the coronal arrangement is so starkly different as to negate that assumption. Here the coronal lobes ascend toward the center in at least a 45 degree angle and are spatulate not acute and I see no umbo on the dorsal surface. The stark difference here and with the pollinaria leads me to place it in a new specie category. I have named this sp. after Tina Paul, originally from San Francisco CA now living in Escondido, California and she is an avid Hoya person. Pedicle calyx and ovaries side view. Enlarged about 8x Pedicel: 1.9 cm long 0.06 cm in diameter. Surface with sparse pubescence enlarging toward the calyx. Calyx: sepals triangular, 0.16 cm long and widest 0.16 cm edge wit a few cilia, edges hyaline, Inside glabrous and slick., no overlap at base, no ligules observed. Ovaries: very stubby 0.11 cm tall and abase pair 0.16 cm wide. 13 Inside surface of the corolla, this surface is pubescent. Lobe apex acute, broad in the center. Sinus - sinus 0.55 cm Apex - center 0.90 cm Widest 0.60 cm Corona. Inner lobes raised and spatulate, dorsal surface cupped, outer lobe obtuse, anther wings with ends thickened and extending a little beyond the sinuses.

Scale thin even when soaked in Kew solution, Inner lobe long and narrow, outer lobe with rounded apical area less so. Anther wing very thick at the apical, lower area. Pollinarium enlarged about 165x. Pollinia wide and short, retinaculum with distinct head, waste area. 14 Pollinium length 0.51 mm widest 0.21 mm Retinaculum length 0.19 mm shoulder 0.12 mm waist 0.08 mm hip 0.10 mm ext. 0.05 mm Translators length 0.10 mm widest 0.04 mm Pollinia inner ends: T Retinacula, with broad hips.
