ORCHIDACEtE 



bifurcated. In O. surigaensis the margin of the labellum is den- 

 ticulate up to the deeply retuse tip, some of the teeth being 

 conspicuously bifurcated. In dried specimens the labellum is pale 

 orange, the sepals and petals nearly white. 



Mindanao, Surigao Province, C. A. Wenzel 01159^ June 4, 1917. 150 

 meters altitude. Epiphyte in forest. Flowers red. 



LIPARIS L. C. Rich. 



Liparis jarensis Ames sp. nov. AfF. L. Glossulae Reichb. f., 

 sed in habitu satis dissimilis. Herba epiphytica. Rhizoma repens. 

 Radices elongatae, patentes, albidae. Folium 2.5-4.5 dm. Ion- 

 gum, 2.3-5 cm. latum, in sicco prominenter nervosum, petio- 

 latum; lamina oblongo-lanceolata, acuminata, acuta, in sicco 

 chartacea, in petiolum elongatum sulcatum 4-6 cm. longum 

 contracta. Scapus cum racemo usque ad 3 dm. longus, quam 

 folium brevior, infra racemum paucibracteatus, bracteis acutis 

 3-4 cm. distantibus. Flores virides, in racemo laxo dispositi, 

 bracteis subtendentibus anguste lanceolatis, circa 1 cm. longis, 

 in sicco scariosis. Pedicelli graciles, elongati, cum ovario usque 

 ad 17 mm. longi, vix adscendentes. Sepala lateralia 1 cm. longa, 

 2 mm. lata, anguste oblonga, acuta. Sepalum dorsale angustius, 

 11 mm. longum, 1.5 mm. latum, acutum. Petala linearia, 13 mm. 

 longa, 1 mm. lata, uninervia. Labellum suborbiculare, 9 mm. 

 longum, 7.5 mm. latum, apiculatum, denticulatum, basim versus 

 cuneatum, prope basim columnae callus late crescentiformis 

 Stat. Columna valde arcuata, super medium alata. 



The flower indicates affinity with Lipaiis Glossula Reichb. f., 

 but the leaves are much narrower than in that species. In several 

 specimens examined the leaf and flower shoot arise from between 

 two erect, rigid, ensiform foliaceous sheaths. By the time the leaf 

 has reached its normal size the flowers produced on the subtend- 

 ing scape begin to expand.
