Michaux’s plant, preserved in the Paris Herbarium, came 
from Lake Mistissini. We have specimens collected by Dr. 
Richardson in Arctic America, and by Kennicott on Elk River. 
The species is thus indicated as high northern in distribution. 
Valeriana pauctfiora, Michx. FI. Bor. Am. i. 1803. 
__ The pappus of this species is not described so far as I am able 
to ascertain. One of the essential characters of Valeriana, as 
the genus is recognized by recent authors, is the development of 
the calyx-teeth into plumose bristles. In V. paucifora, however, 
I'find no indication that this is the case, even in fruit which 
seems to be perfectly mature, which I have from Professor Por- 
_ter, collected by him at Millersburg, Penn., in 1865. In this the 
calyx-teeth remain short and inrolled, are slightly ciliate, and 
about 0.5 mm. long. Inthe related V. Arizonica, A. Gray, the 
fruit of which was not known to the describer at all events at 
the time of description, but which I have from a specimen col- 
lected by Dr, Rusby on Bill Williams Mountain, Arizona, in 
1883, the similar short inrolled calyx-teeth occur. Now both 
these species differ from all other Valerians that I have at hand 
_ 0 examine by their large, slender, elongated corollas, resembling 
in this character the European genus Centranthus. They do not 
agree with Centranthus, however, in other important particulars, 
this genus having an elongated pappus and only one stamen. 
Tam printing this note to call attention to the fruit of V. 
Paucifiora, in the hope that some one may be able to examine it 
when perfectly mature, and to determine whether it ever devel- 
°pes the copious pappus of other species. 
Stevia ovata, Raf. New FI. N. A. iv. 73 (1836). 
A specimen of this plant, which Rafinesque says was collected 
by Walton in “ Texas and Arkanzas,” is preserved in the Col- 
umbia College Herbarium, with Rafinesque’s own label. It is 
quite the same as other specimens labelled Stevia ovata received 
from Meisner and grown in the Basel garden, and from the Liver- 
Pool Botanic Garden sent to Dr. Torrey by Mr. Stead, collected 
in 1820. Whether or not these specimens are all the same as 5. 
ovata, Lag. Nov. Gen. et Sp. 27, which Mr. Hemsley records 
Only from South Mexico, I have no means of ascertaining other
