MEXICO.— SUPPLEMENT. 



[Pistiacecc. 



rect in referring the species to Mr Don's P. radiata, the leaves are constantly quinate, a foot long, slender, 

 slightly scabrous at the margin : the sheaths 2 inches long, brown. The leaves were unknown to Mr Don. 

 P. patula of Cham, and Schlecht. has the leaves only ternate or sometimes quaternate. Good specimens, 

 foliage and fruit of Mexican Pines are much to be desired.

Had. Between San Bias and Tepic We regret there are no glands of this oak, of which we can find no 



description, nor any fertile flowers. The leaves are 4-5 inches long, terminated by a very evident but brittle 

 awn, 2 or 3 lines in length, generally broken on the older leaves.
