ORCHIDACE.E 



obtuse apex, bluntly irregularly and deeply erose on the lateral 

 margins, separated from the middle lobe by a deep scarcely 

 noticeable sinus ; middle lobe porrect, divided as far as the mid- 

 dle by a deep broad sinus, into two oblong rounded spreading 

 lobules, a small triangular tooth at the base of the sinus. Ovary 

 hexagonal. 



Clemens 328 shows several specimens that are smaller than 

 the mature plants of the type. The plants from Lobong Cave are 

 less mature than those from Kiau, with shorter broader leaves 

 (up to 1.2 cm. wide), which have a more fleshy texture. 



Oheronia kinahaluensis is very similar to O. Coste?'iana J. J. 



Sm., but with generally smaller laxer leaves, salmon instead of 



brown flowers, and a very different mid-lobe of the lip. It has 



much narrower leaves, petals which are twice as large, and longer 



lip than O. dubia J. J. Sm. It is almost identical in habit with 



O. ElmeH Ames, but varies in the petals, lip, and color of the 



flowers. (Plate 89.)
