appear to be sufficiently distinct. The first two species are decidedly 

 arborescent, the trunk of S. pallida being often 6 feet high, while the 

 whole plant is often 12 or 15 feet high, and of a much more erect 

 manner of growth than S. cyatheoides. S. squarrosa, on the contrary, 

 is diminutive in comparison with the two others, usually having but a 

 very small trunk-like caudex, or none at all. I have seen specimens 

 not over a foot high, including caudex and all, in luxuriant fructification.

 — It is not improbable that a form of the last species (if the two are 

 really distinct) has been taken for this, in referring it to the Hawaiian 

 Islands. Menzies is, so far as I know, the only authority for this 

 habitat.

 Perhaps this is what Hooker refers to under A. falcaium when he 

 credits it as " very small, whole plant not 4 inches high," to the Ha- 

 waiian Islands. — It is with some hesitation that I have altered this 

 name, but the protensum of Schrader has six years the precedence of 

 that of Kaulfuss. The species under consideration appears to be
