1. Valeriana scandens L. Foliage glabrous. Stems slender, climbing, branched : 

 basal leaves with entire broadly ovate cordate blades : stem-leaves with mostly ternately 

 divided long-petioled blades, the segments ovate, or deltoid-ovate, acute or acuminate, un- 

 dulate or distinctly and shallowly toothed, the terminal one truncate or subcordate, the two 

 lateral ones oblique at the base : panicles axillary and terminal, 1-2 dm. long, its branches 

 zigzag, the ultimate divisions being spikes : flowers very small, their bracts 1-2 mm. long : 

 corolla short-fuunelforra, about 1.5 mm. long : fruit narrowly ovoid.

 or rarely entire cordate long-petioled blades ; upper stem-leaves with pinnately divided 

 blades, with large segments and 1 or 2 pairs of smaller ones, one of which is near the base 

 of the petiole, the larger segments ovate, toothed like the lower leaf-blades : corymbs 

 terminal, 5-10 cm. long : bracts 4-8 mm. long : corolla white or pink, about 2 cm. 

 long ; tube very slender, funnelform above ; lobes about as long as broad, rounded at 

 the apex.

2. VALERIANELLA Moench. 



Annual vernal herbs, with fleshy tissues and usually glabrous foliage. Stems dichot- 



omously branched. Leaves opposite, the basal rosulate: blades entire, toothed, lobed or 



rarely pinnatifid. Flowers perfect, in terminal clustered or corymbose cymes. Calyx

more or less enlarged, sometimes confluent, rarely bursting. Corn Salad. 



Corolla blue or purplish : fruit about twice as broad as thick": species introduced. 1. V. Locusta. 

 Corolla white : fruit about as broad as thick : species native. 



Fruit with the fertile portion fully as wide as the sterile portion. 



Fruit 3-angled. 2. V. amarella. 



Fruit 4-angled. 



Fruit ovoid-tetragonal, with a broad and shallow groove between the sterile 



portions. 3. V. radiata. 



Fruit oblong-tetragonal, with a very narrow groove between the sterile 



portions. 4. V. stenocarpa. 



Fruit with the fertile portion much smaller and narrower than the sterile portion : 

 Empty cavities broad, bladder-like by the infolding of the edges and form- 

 ing a cross-shaped umbilication. 5. V. umbilicata. 

 Empty cavities never infolded so as to make a bladder-like body. 



Empty cavities dilated and divergent, forming a saucer-shaped body notched 



at both ends. 6. T^. patellaria. 



Empty cavities contiguous, with an oblong depression between them. 7. V. Woodsiana. 



1. Valerianella Lociista (L. ) Bettke. Stems erect, 1-4 dm. tall, simple or branched 



throughout : leaves fleshy ; basal and lower stem-leaves with spatulate or oblanceolate 



blades ; upper stem-leaves with oblong or oblong-lanceolate, entire or sparingly toothed 



blades, all obtuse, 1.5-7 cm. long : corolla blue or purplish, funnelform ; tube not longer 



than the diameter of the limb : fruit about twice as broad as thick. [ V. olitoria Poll.] 



In waste places, woods and meadows, New York to New Jersey, Pennsylvania and Louisiana. 

 Spring and early summer. 



2. Valerianella aniar611a Krok. Stems erect, 1-3 dm. tall, usually much branched 

 throughout, or sometimes simple : basal and lower stem-leaves with oblanceolate or spatu- 

 late blades ; upper stem-leaves with oblong or oblong-oblanceolate blades, all obtuse, more 

 or less undulate or crenate, sessile : corolla white, funnelform : fruit 3-angled, with fertile
