Hah. Isle of Leyte, Cuming, n. 310. — Mr. Smith implies that he had under his 

 eye more than one plant which he has called Sagenia calcarea. Dr. Mettenius's 

 figure exhibits one of these, and which clearly indicates what he intends. It 

 seems very different from any other of this difficult group. 



{The following species here brought under § Euaspidium, 58-75 are for the 

 most part referred to Sagenia* by Authors.) 



58. A. (Euaspidium) Pica^ Desv. ; caudex ? stipes a span 

 to a foot long and as well as the rachis and principal costae 

 beneath intensely ebeneous, frond cordate with a deep sinus 

 puberulous firm coriaceo- membranaceous 6-18 inches long 

 simple or trifid or 3-5-foliolate, lowest pair half-ovate bipar- 

 tite or deeply pinnatifid in the lower margin, intermediate 

 pair broad oblong-lanceolate more or less adnate at the base, 

 terminal pinna very large petiolate subrhomboid trifid, the 

 terminal segment large lobato-pinnatifid, primary veins 

 springing from the costae flexuose conspicuous, the rest of 

 the venation anastomoses into hexagonal areoles with lesser 

 ones within them including free short veinlets some of which
