NO. 62  Paphiopedilum rungsuriyanum
Olaf Gruss, Niwat Rungruang, Yongyouth Chaisuriyakul
and Ibn Dionisio

 A very interesting new species Paphiopedilum rungsuriyanum was found from north-Laos and described by Mr. Olf Gruss et al. This new species near related to Paphiopedilum canhii AVER & O.GRUSS but differed by the differebt color of the flower, the shorter and the wider petals, the wider lip and the folded near ovate staminode.
The story is as follows. In the last few years, a large number of plants of the genus as well as other species, came from Laos on the market in Thailand. Frequently in the past few months, a number of very small size plants of the genus appeared as in the trade. Niwat RUNGRUANG, a grower from Thailand also received a number of plants from these collections and when the plants came to bloom in May 2014, he was surprised because he realized that these Paphs were not. Therefore Niwat RUNGRUANG sought contact with slipper orchid specialists in Thailand and Germany and asked for an analysis and identification of the plants, based on several owering plants and detailed picture material (in particular by Olaf GRUSS in Germany).
 Plant: Lithophytic or terrestrial plant with 3 - 5 opposite leaves, a short stem, hardly any distance between the individual shoots. Leaves: Narrow elliptic, rounded off at the tip or indistinct three-lobbed, 10 - 15 cm long, 1.5 - 2 cm wide, sharp unterseits gekielt; the surface is clearly dark and pale green marbled on the bottom gray green marbled, with few hairs at the leave base. Inflorescence: Upright to slightly drooping with 1 or rarely 2 frowers with a length of 5 - 8 cm, 8 mm in diameter, dark purple, covered with whitish to translucent hairs. Flower: 4 - 5 cm in diameter,Petals: Oblong oval, rounded at the end, spread out, 2 - 3 cm long and 1.8 - 2 cm wide, at the
edges whitish translucent hairy, on both sides intensively red-purple veined with wide redpurple edge with whitish color.
