SOME CAUFORNIAN MAPLES. 249 



and indument as are the maples of the whole of Atlantic North 

 America. Of this condition, and of the falsity of that name 

 ^ for any California maple I became very clearly apprehensive 



r while still a resident of the State twenty years since, but only 



recently has my attention been called again to these Californian 

 I, trees, and this time with far more copious material available 



\ than all that I had myself gathered in former years. The fol- 



lowing new species are very clear ; and there are mdications 

 of half as many more in the National Herbarium and in my 

 own, of which the incompleteness of the material precludes 



the satisfactory establishment of the species. 



Acer flabeli*atum. I^eaves on elongated petioles of 3 to 

 6 inches and large, 4 to 6 inches long, widest a little above 

 the middle, there measuring 5J^ to 7^ inches, the base abso- 

 lutely truncate without the suggestion even of a sinus, cleft 

 to the middle only, the 3 main lobes subquadrate-obovate, 

 shortly and broadly lobed at summit, the sinuses very nar- 

 rowly V-shaped, upper face deep-green aud sparsely muricu- 

 late, the lower showing very prominent veins and veinlets and 

 everywhere glabrous except at the forking of the veins, there 

 exhibiting a tuft of short hirsute hairs, but the margin un- 

 evenly hairy with softer hairs ; samaras uncommonly divergent 

 for the group, as well as narrow- winged, fully 2 inches long, 

 the body shortly but stiffly bristly as well as tomentulose, the 

 bristly hairs in shorter form and appressed extending to the 



y2 



undulate.
