J. DiLATA r TA. Shoots creeping: leafits doubly tiled, with little scales 
underneath: branches broader towards the end.

*— Mich. 6. 6— Neck. Meth. 1. 3, at p. 273. 
Leafits circular, in a double row, Neck.; convex, smaller, and shoots nar¬ 
rower than in J. complanata. Involucrum terminating the branches^ 
three-cornered ; Neck.; colour dark green, or reddish. Fruit-stalk one 
line long. Weis. Shoots strap-shaped, lying on one another, forming 
dense roundish patches. Branches distant, winged. Involucrum mostly 
terminating, half a line long. Fruit-stalk very short. Capsule minute, 
globular. Pol. 
(The barren fructification may be seen on the same individual as the fertile, 
though it is far more abundant on separate plants. In this instance, (and 
* some others,) the genus is to be considered both monoeciousand dioecious.

J. tamaris'ci. Shoots doubly compound: fruit-stalks terminal: leafits 
roundish, with appendages underneath: stipulse egg-shaped, 
notched.

Greatly resembles J. dilatata, Neck.; but the shoots are much longer, 
crowded and lying one upon another, more slender, more branched; 
branches of a uniform breadth, blunt at the ends, not closely attached to 
the tree on which it grows, but rather hanging down. The mid-rib is 
more exposed to view, and on the under side appears jointed, and 
covered with small scales cloven at the end. Fruit-stalk terminating, 
very short. Capsule brown yellow. Weis. Dill. Leafits circular, very 
entire. Capsule very minute. Pol. (By no means so common as the last. 
Patches conspicuous from their purplish colour, varying to green in shady 
situations. Hook. E.) 
(Tamarisk Jungermannia. J. tamariscina. E. Bot. J. tamariscifolia . 
With. Ed. 3. &c. Hooker alledges sufficient reasons for adopting the 
alteration now made : considering the name tamarisci , as used by Lin¬ 
naeus in Syst. Nat. and Sp. PI. (though not in FI. Suec.) as most applicable. 
E.) Trunks of trees and rocks. (A rare plant in Lancashire, but found in 
a fir wood near Childwall. Mr. Shepherd. Covering the Juniper bushes 
on the Pentland Hills. Greville. E.) P. Feb.—March. 
J. ex'cisa. Shoots creeping, branched: fruit-stalks terminal: leaves 
tiled, concave, notched at the end: sheathing involucrum in¬ 
versely egg-shaped. Dicks, ii. 11. 
(Hook. Jung. 9— E. Bot. 2497. E.)— Hicks. 8. 7. 
Shoots cylindrical, closely tiled with leaves. Involucrum toothed at the top-
