linear-lanceolate acute segments.

Canons on Williams’ River, a branch of the Colorado, western New Mexico; February 8. In the 
memoir above quoted, Mr. Nuttall does not express any opinion as to the affinities of this genus, 
owing to the embryo being unknown, the seeds in all his specimens being imperfect; but he 
says that it “may well form a Suborder Crossosomese.” On the ticket of a fragment of this 
plant, which he sent us, he has written : Nat. Order Pmoniaceae. Unfortunately, our specimens 
are only in flower, and the ripe seeds are still wanting. Although the stamens are decidedly 
perigynous, and the seeds are furnished with an ample fimbrillate arillus, the plant may never¬ 
theless belong to the tribe or Suborder Paeoniacere. We were once inclined to refer it to tribe 
Spiraese of Rosaceee, to which it has some resemblance in the flowers; but it is destitute of 
stipules, and arillate seeds are not found in that order. We should place this remarkable plant 
in Dilleniaceae, were it not for the perigynous stamens. These are inserted in several series into 
the upper part of a thin disk which, lining the tube of the calyx, projects in a somewhat 
tumid border around the base of the pistils, as in Prnonia.

Mexico.

agrees pretty well with Delessert’s figure, hut we are not confident that it is distinct from B.

This plant occurs also near San Francisco.
