3 inches to a span long petiolatc, from a broad base broad- 

 lanceolate finely acuminate into an incised Cauda, secondary 

 pinnae 1-3 inches long, ultimate pinnules and segments 

 small for the size of the fronds 3-5 lines long cuneate vindi- 

 vided or deeply pinnatifid or 3-lobed, the lobes or segments 

 generally narrow-cuneate sometimes Inroad incised or toothed 

 at the apex, veins flabelliform nearly erect parallel, sori 

 linear rather short 2-1 on a pinnule or segment, often exactly 

 opposite to each other and opening face to face, involucres 

 membranaceous. (Tau. CCIII.) — Lam. Encycl. p. 310. Sw.

 appears to me to be a more compound and luxuriant variety. If this form were 

 peculiar to the East Indies, as it was long supposed to be, that might have favoured 

 the view of the species being distinct, but now Mexico is found to produce the 

 same form, iiccording to Liebmann, and my Portorico specimen diifers in no respect 

 from true laserpitiifoliian.
