Var. B, pubigerum (D. C. syst. 2. p. 28. prod. 1. p. 110.) 
petioles pilose; nodes very hairy. X. H. Native about Con- 
stantinople. Perhaps a proper species. 
Alpine Barren-wort. Fl. March, May. England. Pl. 4 foot. 
2 E. prnna'rum (Fisch. in litt. D. C. syst. 2. p. 29.) radical 
leaves pinnate ; scape leafless. 2.H. Native of Persia, in the 
. province of Gilan. Flowers erect. Fruit pendulous at top of 
pedicels. 
Pinnate-leaved Barren-wort. PI. 4 foot. 
3 E. nexa’npruM (Hook. fl. bor. amer. p. 30. t. 13.) radical 
leaves twice or thrice ternate ; leaflets cordate, bluntly 5-lobed, 
somewhat pilose ; flowers hexandrous; sepals 8; scape leafless. 
. Y.H. Native of North-west America; common in shady pine 
forests at Fort Vancouver on the Columbia, Puget Sound, and 
North California. Caulophyllum gracile, Dougl. mss. Petals 
6, oblong-obovate, cucullate at the apex, each furnished at the 
base on the inside with a spatulate concave yellow appendage.

Cult. The E. alpinum succeeds well in any common garden 
‘soil, and is readily increased by dividing at the root. The Æ. 
pinnatum and E. hexdndrum have not yet been introduced; but 
if they should, it would be advisable to keep them in pots, in a 
mixture of peat, sand, and loam, until their hardiness is ascer- 
tained. 
VI. ACHLYS. (achlys, dimness; obscure plant.) D. C. 
syst. 2. p. 35. prod. 1. p. 112. Hook. fl. bor. amer. p. 30. 
t. 12. 
Lin. syst. Polydndria, Polygynia. Calyx wanting. Corolla 
wanting. Flowers naked, disposed in a dense spike. Stamens 
numerous. Anthers didymous, globose, almost unilocular, bila- 
biate. Stigma dilated, hence concave. Ovary ovate, smooth,

the cell. Herb with a creeping perennial woody trunk, with 2 
or 3 leaves rising from the same root, which are ternate. Leaf- 
lets large, fan-shaped, sessile. Flowers in spikes; those at the 
base of the spikes are rather remote. 
1 A Tripny’tLa (D.C. 1. c. Hook. l.c.) yw.H. Native of 
the North-west coast of America, in shady pine woods among 
moss; common near the shores of the Pacific, about the mouth 
of the Columbia river and at Fort Vancouver, Leéntice triphylla, 
Smith, in Rees’ Cycl. Leaflets with very unequal sides ; upper 
side, or front, coarsely sinuate-toothed or lobed ; lobes blunt, 
finely rayed with nerves. Scapes longer than the leaves, erect, 
slender. 
Three-leaved Achlys. Pl. 1 to 2 feet. 
Cult. This plant will succeed well in any common garden 
soil; and it may be increased by dividing at the root. 
VII. DIPHYLLE'TA (from ĉc, dis, double; and viov, 
phyllon, a leaf; in allusion to each stem of the plant only bearing 
two alternate leaves.) Mich. fl. bor. amer. 1. p. 203. t. 19. and 20.

Lin. syst. Hexándria, Monogynia. Sepals 6, naked on the 
outside. Petals 6, naked on the inside. Stamens 6. Style 
searcely any. Stigma capitate. Berries nearly globose, sessile, 
1-celled, 2-3-seeded: Seeds ovate-oblong. A smooth perennial 
herb. with the habit of Leéntice or Podophyllum, with 2 large 
alternate lobed leaves on each stem. 
1 D. cymosa (Mich. 1l. c.) Yy. H. Native of North Carolina, 
Virginia, Georgia, on the borders of rivulets, on the tops of the 
highest mountains, and on the banks of Columbia river. Leaves 2, 
alternate, large, kidney-shaped, usually profoundly 2-lobed at the 
apex. Flowers white, cymose. Berries roundish, of a bluish- black 
colour. ,

Cymose-flowered Diphylleia. Fl. May, June. Clt. 1812, 
Pl. 1 foot. . 
Cult. This plant will grow freely in any light rich soil, in a 
shady, moist situation, and is easily increased by dividing at the 
root, in the spring. 
Orver VIII. PODOPHYLLA'CEZ. (plant agreeing with 
Pcdophiyllum in many important points.) D. C. syst. 2. p. 31. 
prod. 1. p. 111. . 
Calyx of 3 (f. 33. a.) or 4 sepals. Petals 6-9. (f. 33. b. c.) 
disposed in 2 or 3 series, each series containing the same number 
as there are sepals, the outer series alternating with them. 
Stamens equal in number with the petals, or double that number; 
filaments filiform ; anthers terminal, opening lengthwise on the 
inside by a double chink. Ovary solitary, crowned by a thick 
peltate stigma, which is nearly sessile, (f. 33. e.) Carpels 1- 
celled baccate (f. 33. e.) indehiscent, or capsular opening round 
the circumference at the apex. Seeds numerous, ovate-glo- 
bose, inverted, fixed to the lateral placenta. Albumen fleshy. 
Embryo straight, basilar. Herbs with rhyzomatose roots, 
stalked, peltate-nerved lobed leaves, and 1-flowered bractless 
peduncles. Flowers white. This order is closely allied, on the 
one hand, to the herbaceous species of Berberideæ, but differs 
from them in the anthers not opening by an elastic valve, and they 
are terminal, not adnate. It differs from Nymphidcee in the 
parts of the flower being ternary, or quaternary, as well asin 
the torus being narrow, and in the albumen being fleshy, not 
mealy, and from Papaverdcee, in the plants yielding a watery 
juice, not milky, and in the unilateral disposition of the seeds, as 
well as in the albumen being fleshy, not oily. It differs from 
Ranunculdécee Vere in the anthers bursting inwardly ; but per 
haps the Ranunculdcee Spùriæ ought to be associated with this 
order on account of the dehiscence of its anthers,—Plants inhabit- 
ing humid and shady places of North America, from whence the 
roots are easily imported in a living state, as well as the seeds. 
The roots are purgative. The herb is narcotic and poisonous. 
The berries are eatable, but sour.
