18. EEYTHRONIUM L. Adder's Tongue 



Stem short, simple, scapose, from a deep-seated and elongated membranous- 

 coated eorm. Leaves 2, basal or nearly so. (Before coming into flower, first or 

 second year, the plants are stemless, producing simply one broad long-petioled 

 leaf. ) Flowers large, nodding, solitary, or several and racemose ; perianth- 

 segments distinct with longitudinal nectar-bearing groove and 2 or 4 sac-like 

 or bulbous processes at base, or only the inner segments so provided. Stamens 

 6, hypogvnous, shorter than the perianth. Style 3-cleft with 3 stigmas, or entire 

 and stigma 1. Capsule somewhat 3-angled, loculicidal. — Species 12, North Amer- 

 ica and Europe. (Greek eruthros, red, the color of the flowers in some species.) 



In the Er_vthroniums the bulb (eorm) is annual. The bulb produced last summer will 

 this spring develop the stem and leaves; during the summer a new biJb forms by its side, 

 and by autumn the old bulb will have shrunk to a hard knotty sear, attached on the one 

 side to the new bulb and on the other to a chain of like scars, which form a pseudo- 

 rhizome representing the growth of preceding years. — Carl Purdy, Flora & Svlva, 2:250 

 (1904).
