ORCHIDACEiE 



linear, abruptly rounded, obtuse or subacute at the apex. Lip, in- 

 cluding the basal auricles, about 1.5 mm. long, 1.35 mm. wide 

 across the apical lobes, pandurate, at the base thickened and 

 concave in the middle, extended back into two broadly rounded 

 auricles, gently narrowed to the middle, abruptly dilated above 

 the middle into a pair of spreading lobules which are suborbic- 

 ular, obtusely and irregularly erose, separated by a deep sinus. 

 Ovary cellular-tomentose. 



This is a plant with many related species, hence the name. 

 Oberonia masarangica Schltr. has much longer denser leaves, 

 shorter stems, and erect racemes, but very similar flowers. O. 

 Oxystophylluvi J. J. Sm. has denser, often longer, less falcate 

 leaves, rather smooth perianth, and much smaller lip. O. hispi- 

 dula Ames, while similar to this species in general appearance, is 

 very different in lip features. O. McGregorii Ames has smaller 

 flowers, markedly ciliate sepals, and a different lip. There are 

 several other species related either vegetatively or in flower 

 structure. However, the narrow spreading linear-falcate loosely 

 disposed leaves and the long arcuate racemes are diagnostically 

 characteristic. Great variation in size of leaves and height of stem 

 is manifest. (Plate 89.)
