 Bourbon, Herb. Mits. Paris, in Herb. Nostr., Bory. — A fine handsome species, 

 with intensely black polished stipes and rachis, and principal costac beneath ; 

 long confounded with Aspid. trifoliatum, but very distinct and peculiar to Mau- 

 ritius and Bourbon. 



59. A. (Euaspidium) alatum, Wall. ; caudex creeping?, sti- 

 pites rather distant 1-2 feet long but winged a long way down 

 sometimes almost to the base and there subulato-paleaceous, 

 fronds subcoriaceo-membranaceous 2-3 feet and more long 

 oblong deeply pinnatifid with 4-5 pairs of distant oblong 

 (6-18 inches long and 1-2 wide) or strap-shaped acuminated 

 segments, inferior ones entire or bipartite, primary veins 

 horizontally patent slender, connected by transverse zigzag 

 secondary ones forming areoles which include anastomosing 

 veins with free veinlets, sori small very copious scattered 

 without order arising from reticulations (hence compital) not 

 extending to the margin, involucre small, but I believe rather 

 cordate than orbicular peltate (as erroneously represented
