branaceum, Hemsl., but differs in having larger leaves which are entirely 
devoid of stellate hairs on the upper surface, in having very sparingly 
hirsute not tomentose petioles, and finally in having from 6 to 9 lateral 
veins on either side of the midrib instead of 4 or 5. 
Valeriana calcicola, n. sp. An erect herbaceous annual: stem 
simple to the inflorescence, springing from a subterranean tuberous root, 
8 to 9 dm. high, densely puberulent below, glabrous above: radical 
leaves not seen: stem leaves 1 to 3 pairs, bipannatisect, oblong to ob- 
long-ovate in general outline, 4 to 9 cm. long, one-half as broad, glabrous 
or under a lens slightly puberulent beneath ; segments linear to linear- 
oblong, 4 to 15 mm. long, 1 to 3 mm. broad, obtuse; the uppermost 
pair of leaves much reduced: inflorescence a terminal paniculate eyme, 
when fully expanded 2 to 2.5 dm. long, 1 to 1.2 dm. broad; bracts 
short, narrowly ovate, 1 to 3 mm. long, acute, often subconnate at the 
base: flowers sessile, perfect, proterandrous: corolla subcampanulate, 
2.5 to 8 mm. long, 5-lobed to the middle, purple; tube strongly gibbous 
at the base, densely villous in the throat; lobes at first erect, later 
reflexed: stamens 3, at the time of dehiscence of the anthers subin- 
cluded, later exserted : fruit somewhat flask-shaped, 3.5 mm. long, 2 mm. 
broad at the base, compressed, plano-convex and usually pubescent om 
the side of the fertile cell, 3-ribbed and glabrous on the other side 
with the lateral ribs prominent and rounded on the back ; the persistent 
plumose calyx-teeth as long as or longer than the body of the fruit.

Valeriana macropoda, n. sp. An herbaceous perennial: stem 
simple, about 3 dm. high, rising from a tuberous root, glabrous or very 
sparingly puberulent : leaves pinnatisect with numerous mostly crowd 
primary divisions and linear obtuse to acute ultimate segments, rather 
thick and firm in texture; radical leaves including the petiole 10 a 
18 em. long, 3 to 6 em. broad, rhachis rather broad and continuous 10 
breadth with the petiole, the latter 6 cm. or less in length; stem-leaves 
1 to 2 pairs, the lower usually petiolate, the petioles ciliate and frequently 
connate, the upper pair of leaves sessile and much reduced often to mere 
bracts : inflorescence cymose, either simple or subcorymbosely disposed 5 
bracts small, lance-linear, 2 mm. or less in length, acutish, greet with 
scarious margins: flowers essentially dioecious, sessile: corolla of the 
staminate flowers tubular-funnelform, somewhat unequally 5-lobed, white 
or roseate; tube about 3 mm. long, slightly gibbous at the base, spat- 
ingly pubescent within; lobes ovate-oblong, about 1 mm. long; obtuse +
