H O YA NEW A photo by the late Mary Ann Cajano, Los Banos, Philippines, as yet unpublished. Oh There it is ! A pdf publication devoted to the Genus Hoya ISSN 2329-7336 Volume 8 Issue 2 July 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 1 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. Hoya matiensis Kloppenburg 2018 2.

Pedicels: 2.0 cm x 0.1 cm enlarging toward the apex. Calyx: top view enlarged about 8x, large and with overlapping sepals, ligules long. Sepals, ovate 0.36 cm long and 0.30 cm wide; about the center, glabrous. Ovaries: narrow cone shaped 0.16 cm tall 0.10 cm at base of pair, glabrous. Top view of a flower enlarged about 8x, corolla lobe extending to bottom of picture. Outside is glabrous inside puberulous may be papillose ? Sinus - sinus 0.60 cm Sinus - apex 0.57 cm Apex - center 0.95 cm 3 Bottom view of the corona enlarged about 8x. Lobes are very plump, channeled to near sinuses, Anther wings with broad sides and prominent, outer apex subacute. Thickened central column. Apex - apex 0.40 cm Apex - center 0.44 cm Widest 0.24 cm Aw. - aw. 0.20 cm Top view of the corona enlarged about 8x. Inner lobes do not quite reach the center, are extended round to sub spatulate.

Similis sp. sed pedicilis longior 2.0 cm contrastre 1.5 cm et sepala non ciliatus ovatis; corolla diametro complanatus brevior 0.5 cm contrastre 0.9 cm, differt. In addition the pollinia here is not as in Dr. Schlechter’s drawing. Here again we have a species that is highly variable, many color variations that also have many differences in the flower parts. This subspecies differs from Dr. Schlechter’s type in that the sepals here are shorter. The pedicels here are longer 2.0 cm vs. 1.5 cm, also here the corolla flattened is only 0.50 cm in diameter vs. 0.90 cm inside. Pedicel: enlarged about 16x. 2 cm long 0.09 cm in diameter, curved, terete, glabrous, enlarging as it approaches the calyx. Calyx: enlarged about 16x. Sepals are 0.16 cm long and at the base 0.15 cm wide with a slight overlap, thickened in the center and ciliate otherwise glabrous, outside granulose. Ovaries: are columnar 0.13 cm tall and base pair 0.12 cm wide, glabrous drying dark in color. Bottom (outside) view of the flower enlarged about 8x. Ends and sides of the corolla lobes turn under are dark in color dried, center greatly thickened, with a collar protruding outward 0.04 cm long. Sinus - sinus 0.25 cm Sinus - center 0.25 cm 7 Inside (top) view of the flower enlarged as above. The coronal lobes are sharply keeled above and touch in the center. Here the anthers are not compressed and creped between the lobes but have loosened up and expanded. They are thin membranous 0.15 cm long and at the base 0.12 cm wide. The coronal lobes exceed the corolla sinuses. Corolla inside pubescent. Pollinarium enlarged about 165x. Pollinium length 0.63 mm widest 0.29 mm ext 0.05 mm Retinacula length 0.55 mm shoulder 0.25 mm Translator length 0.30 mm depth 0.03 mm Caudicle 8 bulb, diam 0.07 mm Translator/caudicle type: ls/o Pollinia inner end type: R Measurements difficult, pollinium of different width possibly the one on top is folded a little. Retinaculum globose and hard to discern features. The translators appear to twist as they exit the retinaculum. 9 Hoya pseudobicolensis Kloppenburg 2018 ISSN 1655-3179 Hoya pseudobicolensis Kloppenburg sp. nova, holotypus 5294 (CAHUP) hie designatus. Similis Hoya bicolensis sed foliis ellipticus et apicie apiculatis non ovato & apice subacuminatus, aliis partibus breviora. Corolla diametro complanatus brevior autem pollinia iam 0.40 mm-0.42 mm contrastre 0.35 mm, differt. This new sp. is similar to Hoya bicolensis Kloppenburg, Siar & Cajano 2014 and Hoya camphorifolia Warburg 1904 but the foliage is different. Most parts are smaller except the pollinia are longer. Collected by Blass Hernaez on 17 March 1990, UP Landgrant, Quezon, Philippines. . Determination: closest to Hoya bicolensis Kloppenburg & Siar but possibly in Sect. Otostemma sp. Internodes: 5.5 - 10 cm. long Foliage: elliptic apiculate apex acute, base slightly rounded, glabrous, triplinerved, blade 7.8-12.6 x 3.5 - 5.4 cm.; petiole 2.7 cm. long glabrous.0.90 cm contrastre 0.94 cm, Peduncle: extremely short here with rachis fasciculate. Photo and data 3/29/99. Pedicel: filiform, terete, glabrous 1.0 cm long 0.05 cm diam. Calyx: short, broad, triangular sepals, ciliate, outside surface granulate, glabrous. Ovaries: dome shaped 0.07 cm tall and base pair 0.05 cm wide, glabrous. Flower, corolla dark, with corona in center sitting atop a column, flowers very small appear to be in Section Otostemma. Outer lobes raised above the center, dorsal surface sway backed with center raised, outer apex rounded, thin, prominent anther wings. Inner lobes round (dentate?) sloping outward, dorsal with central ridge. Sinus - sinus 0.18 cm Sinus - center 0.15 cm Sinus - apex 0.30 cm Apex - center 0.45 cm Widest 0.25 cm 10
