herbaria ; and more diligent collecting and collating of Oreo- 
carya in particular, from all parts of the wide range of country 
which the genus occupies, is greatly to be desired, and will 
doubtless lead to the due recognition of several more species 
than we can now define. 
OREOCARYA. 
Inflorescence leafy-bracted, thyrsoid, (in one or two species 
rather racemose-paniculate); pedicels filiform, persistent. 
Calyx 5-parted to the base; segments lanceolate, their mid- 
vein seldom obvious, pilose-hispid, in fruit more or less 
spreading or recurved. Nutlets smooth or tuberculate or 
rugose, not carinate, their margins acute or scarious-winged, 
ventral groove usually closed, and at base divarieate.—Stout, 
coarse biennials and perennials, canescent or pilose-hispid ; 
leaves mostly radical. Plants of the mountain districts of 
western North America, from Chihuahua to Manitoba and the 
eastern borders of California and Washington Territory.—
