branaceum, Heinsl., 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 cyme, 

 when fully expanded 2 to 2.5dm. long, 1 to 1.2dm. broad; bracts 

 short, narrowly ovate, 1 to 3 mm. long, acute, often subconnate at the 

 base : flowers sessile, perfect, proterandrous : corolla subcampanulate, 

 2.0 to 3 mm. long, 5-lobed to the middle, purple; tube strongly gibbous 

 at the base, densely villous in the throat ; lobes at first erect, later 

 refiexed : 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 on- 

 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 crowded 

 primary divisions and linear obtuse to acute ultimate segments, rather 

 thick and firm in texture ; radical leaves including the petiole 10 to 

 18 cm. long, 3 to 6 cm. broad, rhachis rather broad and continuous in 

 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 ; 

 bracts small, lance-linear, 2 mm. or less in length, acutish, green 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, spar- 

 ingly pubescent within ; lobes ovate-oblong, about 1 mm. long, obtuse :
