17 . Botany— New and rare plants 
of Maryland near Baltimore. 
By C. S. Rafinesque. 
Many rare or Southern plants be- 
gin to appear near Baltimore. I no- 
ticed many in 1804 and 1819. Also 
in my visit and herborizations this 
year. 
Some are preserved in the herba- 
rium collected by Mr. Elias Durand 
(now of Philadelphia,) presented to 
the Academy of Natural Sciences 
of Baltimore, where I saw them. 
Such are the. 
Andromeda marginata of Duhamel. 
— Acuminata? Duh. 
— — — frondosa of Wildenow. 
Ascyrun pumilum. 
Inula or Diplogon argentcum. 
Chrysogonum Yirginianum L. this 
very rare plant 1 found in West 
Yirginia also. 
In the Herbarium of Dr. W. Fish- 
er of B. are some other rare plants, 
such as 
Helonias angustifolia. 
Stachys hyssopifolia. 
Calamintha caroliniana. 
One of both Herbals were quite 
new undescribed and nameless. 1 
shall therefore name them and cha- 
racterize them as follows. 
Pyrola (or Chimaphila ) durandi 
Raf. Leaves few, shortly petiolate, 
ovate remote serrate, acute, unspot- 
ted. Stem naked above uniflore, 
flower nodding, calyx 5 toothed, ob- 
tuse. 
Discovered and collected by Mr. 
Durand. It belongs to the S. G. 
Chimaphila very near to P. macu- 
lata; but differs by broader unspotted 
leaves and uniflore stem. Is ft a 
variety of it? Only 4 or 5 inches 
high, with only 3 leaves, calyx short 
with obtuse teeth, petals white ob- 
ovate obtuse, stamens bifid short, 
stigma sessile thick depressed. 
Orchis (or llabenaria ) Croce a 
Raf. Stem angular, leaves lanceolate 
acuminate, spike short cylindrical, 
bracts lanceolate equalto flowers, 
spur slender equal to ovary, petals 
ovate acute, labellum nearly similar 
hardly longer, entire. 
Discovered and collected by D. 
W. Fisher. Yery different from 
0 . citiaris , flowers smaller, saffron 
color, not ciliated. Slender plant 
15 inches nigh. Probably an Habe- 
naria. 
18. Six New Firs of Oregon. 
Lewis and Clarke discovered and 
noticed without names, many years 
ago, several fine Fir trees of the Ore- 
gon or Columbia country. These I 
named and characterized in 1817 in 
my Florula Oregonensis, and since 
sent them to Prof. Becandolle. I 
now give here my names and speci- 
fic characters of those 6 new sp. of 
the Genus Mies of Jussieu, &c. 
1. Miestrigona R.' Gigantic Fir 
(First Fir L. C.) bark and branches 
scaly, leaves densely scattered, pe- 
tiolate trigone acuminate and stiff— - 
Stated to be the largest tree of North 
America, some reaching 300 feet 
high, 200 without branches, and 42 
feet around. Petiols trigone also, 
leaves 3-4ths of an inch long, l-10th 
wide. 
2. Jlhies heterophylla -R, Odd 
leaved Fir (Second Fir L. C.) bark 
rimose, leaves distichal petiolate 
very unequal, sulcate above, glau- 
cous beneath, cones terminal ovate 
minute flexible— Reaching 180 feet 
high and 6 feet diameter. Leaves* 
from 1 -4th to one inch long, but all 
l-20th wide. Is it a variety of the 
Spruce Fir? 
3. Jlbies aromatica R. Aromatic 
Fir (Third Fir L. C.) branches bul- 
late balsamiferous, leaves densely 
scattered, forming S rows, sessile, 
lanceolate obtuse, flexible, sulcate 
and shining above, gibbose beneath. 
Reaching 100 feet high, blisters on 
the branches filled with a fine aro- 
matic balsam. Leaves very small 
1 -8th of an inch long, 1-1 6th wide. 
4. Mies microphylla R. Small 
leaved Fir (Fourth Fir L. C.) bark 
rimose, branches not bullate, leaves 
densely scattered, forming 3 rows, 
sessile, sublanceolate acute — Reach- 
ing 150 feet high. Like the last, 
but yielding no balsam, and with
