2. NOTES ON CRITICAL SPECIES. 
IRIS VERNA L. Sp. Pl. 39. 1753. 
I have seen two collections of the spring Iris during the past 
season, both from North Carolina; the one was made by Mr. A. 
M. Huger in the mountains and the other by myself in the central 
part of the State. I find that two of its striking features have not 
been recorded: first, the remarkable elongation of the leaves, which 
often reach a length of 3-4 decimeters, and second, the odor of 
the flowers, which almost exactly imitates the fragrance of sweet 
violets. 
ANEMONE TRIFOLIA L. Sp. Pl. 540. 1753. 
While walking along a small stream just west of the Falls of 
the Yadkin river, last spring I was astonished to find fine plants 
of Anemone trifolia. The species has only been known to exist in 
America on the higher parts of the Alleghanies, chiefly in the 
Southern States, but here, in the central part of North Carolina at 
an elevation of only 200-300 feet above the level of the sea, the 
species appears as typical as anywhere. 
_ CARDAMINE PARVIFLORA L. Sp. Pl. Ed. 2,914. 1763. 
Virginia seems to have been the southern recorded limit for 
this species but now Mr. A. M. Huger sends us good specimens 
from the mountains of Polk County, North Carolina. 
DiaAMoRPHA PUSILLA Nutt. Gen, 1: 293. 1818. 
The geographic range of this curious plant is gradually ex. oes 
panding. I have recently found the species at various points in 
northern Georgia andin 1894and 1895 met withit on Dunn’s Moun- . 
tain in Rowan County, North Carolina. The outlying stations zi see 
its distribution as we pave it haahcaayons Py. specimens are:
