218 VALERIAN FAMILY. 



LIX. VALERIANACEJ!, VALEKIAN FAMILY. 



' Herbs, with opposite leaves, no stipules, calyx coherent with 

 the ovary, which has only one fertile, one-ovuled cell but two 

 abortive or empty ones, and stamens always fewer than the 

 lobes of the tubular or funnel-form corolla (1-3, distinct), and 

 inserted on its tube. Style slender ; stigmas 1-3. Fruit small 

 and dry, indehiscent ; the single hanging seed with a large 

 embryo and no albumen. Flowers small, in clusters or cymes. 



* Lobes of the calyx many and slender, but hardly seen when in flower, being rolled 

 up inwards around the base of the corolla ; in fruit they unroll and appear as 

 long plumose bristles, resembling a pappus, like thistle-down. 



1. VALERIANA. Corolla with narrow or funnel-form tube usually gibbous at the base 



on one side, but not spurred, its 5 spreading lobes almost equal. Stamens 8. Akene 

 1-celled, the minute empty cells early disappearing. Boot strong-scented. 



* » Lobes of the calyx of a few short teeth or mostly hardly any. 



2. VALERIANELLA. Corolla funnel-form, with 5 equal or rather unequal spreading 



lobes. Stamens mostly 3. Akene-like fruit -with one fertile and two empty cells, or 

 the latter confluent into one.
