Poltgonum: Hartavrightii, n. sp. Persicaria, Digyna; strigoso- 

 hirsutum vel glabellum ; caule subpedali erecto striato ad apicem usque 

 crebre as [ualiter folioso ; foliis lato-lanceolatis utrinque acutis vel ob- 

 tusiusculis breviter petiolatis ; ocbreis medio foliigeris hypocraterimor- 

 phis, limbo foliaceo brevi reticulato repando setoso-ciliato ; pedunculo 

 erecto eglanduloso spicam plerumque solitariam densam cylindraceam 

 gerente ; bracteis pedicellos superantibus ; perigonio eglanduloso roseo; 

 staminibus 5 ; stylo profunde bifido. — Sedgy bogs, New York, from 

 Herkimer to Yates County, and Michigan. — Fruit unknown. I col- 

 lected this almost forty years ago at the head of Cayuga Lake, along 

 with the remarkable P. amphibium var. MuMeribergii of Meisner, 

 which is widely distributed in North America. I saw it several years 

 ago, in company with the Rev. Professor Paine, in a high bog near 

 the southern borders of Herkimer County, but not in flower. I have 

 also a well-developed specknen from the State collection in Michigan. 

 Not regarding the stipules, it had been taken for one of the various 

 puzzling terrestrial -varieties of P. amphibium, or, when the stipules 

 were noticed, for an undeveloped condition of P. Careyi. But my 

 attention having been called to it by Dr. S. Hart Wright, of Perm Yan, 

 who finds it in open bottom land, among Carices, at Dundee, Yates Co., 

 New York, I am desirous that it should bear his name, as the real 

 discovei'er of its specific characters.
