BOTANY. 
branclilets nodding as in that species. Indians are said to use the berries as food. Travellers 
call this and the following species Sweet-berried Cedar. The seeds are as large as a small pea, 
and the shell is very thick and hard. The hranchlets are about a line and a half in diameter. 
Leaves nearly as broad as long, very closely appressed, (there are no acicular ones in any of our 
specimens), obtuse, or sometimes rather acute, convex and marked with a depressed gland. 
Juniperus pachypieuea (n. sp.): arborea ; foliis omnibus squamiformibus ovatis incrassato- 
gibbis acutiusculis, dorso glandula elliptica impressa; ramulis obtuse quadrangulatis, fructiferis

in Sitgreaves’ Report , p. 173. On the Zuhi Mountains, Western New Mexico. This is the 
thick-harked Juniperus of Captain Sitgreaves. It seems to he undescribed, and is distinguished 
from the preceding species by the character of the hark, and by the berries (which are also very 
large and sweet) being 3-seeded. From the gland of each leaf a little drop of turpentine exudes. 
It is possible this may be J. Mexicana, ScMecht., which has berries half an inch in diameter ; 
but in that species the leaves are acuminate, and the berries conspicuously tuberculate, espe¬ 
cially at the apex. 
Juniperus occidentalis, Book. FI. Bor.-Amer. 2 ,p. 166. J. Andina, Nutt. Sylv. 3, p. 95, t. 
110. Common on the mountains of New Mexico, in various places along the route as far as the 
Zuiii mountains. The glands are very obscure in the young leaves, but are plainly to be seen, 
in the older ones. The berries are larger and the branclilets much stouter than in J. Yirginiana. 
Juniperus Yirginiana, Linn. Spec.p. 1471; Michx. Sylv. 2 ,p. 353, t. 155. Near Zuiii, Western 
New Mexico. Resembles the eastern plant, except that the leaves are all scale-like, and the 
berries are a little larger. 
LEMNACEiE. 
Lemna trisulca, Linn. Spec. 1, p. 1376 ; Kunth, Enum. 3, p. 5. Stagnant waters, near San 
Francisco ; mixed with Azolla Caroliniana ; also on San Gabriel creek, California. We have 
never seen North American specimens of this species in flower or fruit. 
Lemna minor, Linn. 1. c.; Kunth, l. c. On the surface of running water ; Williams’ Fork of 
the Colorado of California ; not in flower. 
. TYPHACEiE. 
Typha latieolia, Linn. Wet places, near Shawneetown, on the Canadian ; August; in fruit. 
NAIADACEZE. 
Potamogeton HYRRiDUs, Michx. FI. 1, p. 101. In tributaries of the Canadian River ; August; 
with mature fruit. Easily distinguished by its cristale spiral fruit. 
Potamogeton pectinatus, Linn.; Torr. FI. N. York , 2, p. 257. With the preceding. Nutlets 
obovate ; the pericarp very thick, with a small lunate cavity. 
JUNCAGINEiE. 
Triglochin maritimum, Linn.; Torr. FI. A 7 . York, 2, p. 261 ; Kunth, Enum. 3, p. 145. Low 
places in reach of the tide ; San Francisco and Corte Madera, April. The fruit, in some of the 
species, agrees very well with Nuttall’s T. elatum, which we fear is not distinct from this species. 
ALISMACEJE. 
Damasonium Calipornicum, Torr. in Berth. FI. Hartw.p. 341 :* foliis oblongis sen lanceo-
