Apparently only collected once. Close to Philibertella 
elegans (Decne.); but differing in its slightly less acute corolla

stamineal crown in Piilibertella elegans are vertically flattened, 
acute and almost petaloid, whereas those of P. Zorreyi are truncate, 
rounded or flat on top. 
Original locality, Rocky Hills on the Cibolo, a tributary of 
the Rio Grande, southwest Texas.

Plants from Nez Perces County, Idaho. 
By A, A. HELLER, 
(PLATES 309, 310.) 
Four months of the season of 1896 were spent in northern 
Idaho by Mrs. Heller and myself, during which time many inter- 
esting species were collected. Among these a dozen or more 
seem to be new, and have already been distributed as such, 
although not yet described. As soon as possible a complete re- 
port on the work will be published, with descriptions of the new 
species, and notes on all of the others. The following new and 
noteworthy species are discussed in this paper : 
POA SCABRIFOLIA n. n. 
Poa filifolia Vasey, Cont. U.S. Nat. Herb. 1: 271. Not Schur. 
The very appropriate name which Dr. Vasey gave to this 
beautiful species, is not tenable on account of the earlier Poa fil- 
folia, published by Schur, in Enum. Pl. Transs. 768. 1866. It is 
plentiful at the type locality, on the left bank of the Clearwater 
river, near the Upper Ferry, east of Lewiston. 
RANUNCULUS ARCUATUS N. n. 
Ranunculus tenellus Nutt.; T. & G. Fl. N. A. 1: 2 * 1838. 
Not Viviani. .
