A New Species of Fryllania. — Frullania Pe/msylvanica, n. sp. 
Dioica. Caulis e basi araphigastriorum repens^ dichotomo-ramosus; 
folia imbricata, plana, ovata, mucronata, rarius obtusa, integerrima, 
cellulis valde chlorophyllosis, marginem versus minoribus basi valde 
dilatatis, plus niinusve regulariter hexagonis, parietibus validis ; in- 
crassatio angulosa subnuUa. Auricula denudata, e margine folii ori- 
unda, oblique a caule distantia, majuscula, cucuUato-rotunda, sub 
orificio leniter contracta, ultra folii marginem demissa ; araph. sub- 
imbricata, plana, late ovata, caulem excedentia, profunde partita, 
sinu angusto obtuso, laciniis ovatis, longe acuminatis, conniventibus; 
amenta mascula elongata, laxe foliosa, in ramulis parvis lateralibus, 
bracteis complicatis, lobis sub^qualibus ovatis obtusis; perichaetia 
in ramulis longioribus apicalia, saepe ad basin dichotoraiae, fob iny. 
complicata, integerrima, lobulis (ventrale minori) ovatis, acuminatis, 
basi valde angustatis; amph. invol. magna, carinato-concava, pro- 
funde partita, laciniis ovatis, longe apiculatis, integerrimis vel uno 
alterove dente munitis. Perianthia desunt.

The plant is of about the size o{ Frullania dilatata, but the color 
is a dull olive-green. The tufts are depressed, and creep over rocks 
or over other Hepaticse. According to the diagnosis of Mr. Austm s 
F^ Leana, our plant must stand near it. I am not, however, in pos- 
session of the latter plant, though I do not doubt that they are two 
distinct species.

Gerardia tenuifolia, Vahl, parasitic— To my knowledge, only 
those species of Gerardia that belong to the section Dasystonia (such 
as G. flava and quercifolid) have thus far been proved to be parasitic 
(cf. Gray, Struct. Bot, p. 38, and Flora of N. A., p- 291). I have 
recently found that Gerardia tenuifolia, Vahl, section Eugerardia, has 
its roots amply provided with haustoria, the structure of which I 
hope to be able to describe at some future time.

Note on Abutilon. — The involucre, so common in Malvace(E, is, as 
every one knows, omitted in Abutilon^ which, however, retains an in- 
teresting reminiscence of it in the joint seen in the peduncle some 
little distance below the flower. To-day one of my students sho^yed 
me a specimen bearing one minute bract at this joint in the Abutilon 
striatum of the conservatories.

Pinus rigida in Minnesota. — In my note on Pinus Banksiana, in- 
cidental refererxe was made to Pinus rigida. I saw but young trees 
without cones in these outskirts of the forests' westward march. 
Prof. Sargent, who is very familiar with the forestry of that region, 
kindly suggests that the trees were of Pinus resinosa — the former 
species not extending so far. Thomas Meehan.
