PsATllYROTES riLiFERA. P. annuce et P. ramosissimce affinis, 

 pube quasi intermedia, sed foliis lato-rhomboideis basi cuneatis 

 semper iiitegerrimis pilis longissimis araclinoideis multi-articulatis 

 ciliatis; involucre oblongo, bracteis fere linearibus erectls ; acheniis 

 (immaturis) oblongis pilis brevibus hirsutis. — S. Utah, near Kauab,

Lu.piD0SrARTU3i SQUAMATUM. Tetradymia (Lepidosparton) squa- 

 mata, Gray, Proc. Am. Acad. ix. 207, & Bot. Calif, i. 408. I find 

 it impossible to retain this singular shrub in Tetradymia ; and the 

 regularly imbricated chartaceo-scarious bracts, along with the acutish 

 style-lips, give good gejieric characters. 



Cacaliopsis Nardosmia. This striking plant, which I at first 

 named Cacalia Nardosmia, in Proc. Am. Acad. vii. 3G1, and later 

 fviii. 601) followed Benth. & Hook. Gen. PI. ii. 247, in referring to 

 Adenostyles, finds its wliolly appropriate position in the subtribe 

 Tussilaginece, between Petasites, of which it has the habit, and Luina. 

 The style is not altogether that of EupatoriacecB, although approach- 

 ing it, and the flowers are yellow. The anthers are quite entire at 

 base, but otherwise as in Luina. While the specific name indicates
