ORCHIDACE.E 

 basis of priority Mr. Rolfe is justified in taking up Cordula, but 

 surely we may hope that Paphiopedilum will be added to the 

 list of genera which one must retain regardless of priority. Cor- 

 dula, if adopted, will be most inharmonious in a group which 

 has been distinguished by uniformity in the termination of its 

 generic names. 



Two of Pfitzer's subgenera of Paphiopedilum are represented 

 in the Philippines. 



I. Subgen. ANATOPEDILUM.

2. Paphiopedilum philippinense (Reichb.f.) Stein Orchideenb.

 Botanical Magazine, t. 5508. "Associated especially with Cym- 

 bidium Finlaysonianum on open cliffs and boulders, above reach
