I believe that this southern plant is specifically different from 
P. Caroliniana, Michx. As pointed out by Hooker, the stam- 
inodia are very slender and exceed the anther-bearing stamens; 
the flowers and leaves are usually larger; Hooker further remarks 
that these characters are retained in cultivation. I have never seen 
elongated staminodia in our common northern plant, and am very 
familiar with it in the wild state. The identity of DeCandolle’s 
and Hooker’s plants appears to be satisfactorily established. 
_ We have it from North Carolina, (Rugel, Dr. Gray) Florida, 
(Chapman). DeCandolle’s plant came from the Cherokee country, 
and Hooker’s from Louisiana. There may be some doubt as 
to whether this, or what we are calling Caroliniana, is really the 
plant of Michaux, because the specimen of it is missing in his 
herbarium at Paris. 4 
AMMANNIA KOEHNEI, n. sp. Ammania humilis, B. T. & G. 
Fl. N. A. i. 480 (1840). 
Erect, glabrous, 6/-20/' high, at length freely branching. 
Leaves obovate, oblonceolate, or somewhat spatulate, obtuse or 
obtusish at the apex, the upper ones clasping and more or less 
auriculate at the base, the lower narrowed and sessile, or taper- 
ing into a short petiole; flowers 1-3 together in the axils, sessile; 
petals purple? fugacious; stamens very short, not exserted ; 
style very short; capsule enclosed by the calyx. 
In swamps, Hackensack marshes, New Jersey (Torrey ; 
Leggett) to Florida. Named in honor of the distinguished 
monographer of the Lythrariez, Dr: E. Koehne, of Berlin. The 
species cannot be referred to A. /atifolia, L., which has auricu— 
late, linear-lanceolate leaves and no petals. 
Epilobium lineare, Muhl. Cat. 39 (1813). 
My remarks on this species in reviewing Professor Trelease’s 
recent Revision of the North American Epilobia (BULLETIN, 
this volume, p. 226), where I suggested that the name £. o/igan- 
thum, Michx. (1803) should have been taken for it, are quite 
wide of the mark, for the original in Michaux’s Herbarium is £. 
palustre, L., as determined there by Haussknecht. 
Epilobium glandulosum, Lehm. 
Professor Trelease included this species in his treatment of 
the East American members of the genus in the sixth edition of 
Gray’s Manual, but in his Revision, published subsequently, he
