8. Archidium Hallii, 7. ss —A congeneribus flore masc. in caule 
(vel ramulo?) proprio terminali distinguitur—Texas, Wa//.—Leaves 
with the areolation very lax (much as in A, tenerrimum, Mirt.), the 
margins often obscurely recurved, the base (as in all the species) 
more or less echlorophyllose, the costa often long excurrent ; calyp- 
tra of the genus. 
9. Archidium Ravenelii, . s.— Paroicum; caule brevi in- 
ferne arena abruto magis minusve diviso, foliis inferioribus dissitis 
ovatis minutis appressis vel (et illis in innovationibus sterilibus) 
majoribus apertis breviter laxissime areolatis, superioribus raptim in 
rosulam vel gemmulam congestis multum majoribus arctissime im- 
bricatis late ovatis vel ovato-lanceolatis mmagis minusve acuminatis 
acutis vel sepe obtusis integerrimis concavis margine versus basin 
spatio lato hyalinis, costa sub apice evanida vel breviter excurrente, 
reti laxissimo rotundo-ovali vel rhombeo versus basin longiori et 
paulum latiori; capsula calyptraque generis.—South Carolina, 
Ravenel ; Florida, /. Dounell Smith—Nearest to A. tenerrimum, 
but, judging from a few stems taken from Drummond's Southern’ 
Mosses, No. 11, and kindly sent to me by Mr. James, that has the 
longer sterile stems clothed with much narrower, erect, very acute 
leaves with a rather close areolation; while the comal leaves of the 
fertile plant have a narrower areolation and a longer, more excurrent 
costa. . 
1o. Sphagnum serratum, ~. s.—Habitu foliorum forma et tex- 
tura ab Sph. cuspidato haud notabiliter dissimile, distinctissimum 
tamen caule strato corticali triplici et ultra e cellulis majusculis for- 
mato et ab ligneo vix distincto, ramulis magis tereti foliosis, foliis 
caulinis majoribus, ramulinis seepe latissime marginatis etiam tota 
longitudine (vel spe solum parte superiore) distinctissime remote 
serratis siccitate margine minus distincte undulatis.—St. Augustine, 
Florida, 7. Dounell Smith. : 
The lower branch leaves are sometimes entire on the margin, 
while the upper ones are always serrate above the middle. Those 
of the comal branches are often, if not always, serrate to the base. 
Some of the leaves are broadly margined, while others on the same 
branch are either scarcely at all or interruptedly so. The apical 
leaves are remarkably long and narrow (almost linear), and more or 
less spirally contorted above the middle. Pores very small and in- 
distinct or none. 
§ rs0, Pinus Mitis.—The attention of Botanists living in the 
Middle States is directed to this tree, which has become rare in the 
North. As one of the most valuable of North American timber 
trees, attention has been drawn to this species as suitable for forest 
culture, in many parts of the United States, and it is desirable to 
procure seed for this purpose from as far north as possible. . «.. 
According to the younger Michaux Pinus Mitis was found, in his 
time, in New York, Connecticut and Western Massachusetts, and Mr. 
Lapham includes it in his catalogue of Wisconsin plants, but there 
is no evidence that this tree grows so far north at the present time.
