Dendrobium leytense in general habit resembles D. piesto- 



:ulon Schltv., from which it differs in its broader leaves and more 



rongly complanate stems. The labellum is not at all fleshy, or 



ickened at the tip, in dried specimens. Besides the type I have 



:amined many specimens collected by Wenzel (0415) in Leyte, 



hich bear flowers 1 cm. long with lips 9 mm. long. From the 



aterial at hand the sepals and petals appear to have been yel- 



wish, the labellum tinged with pale purple.

 height. Altitude 60 meters above sea level. Flowers greenish-yellow and
