closely contiguous parallel cells lateral or slightly introrse. Stigmas, or styles, 

 Btigmatic down the upper side, recurved-diverging from the globose ovary, 

 long and thread-form, deciduous. Berry globose (dark purple), 3-celled, few- 

 seeded. — A perennial herb, with a simple slender stem (1-3° high, clothet. 

 with flocculent and deciduous wool), rising from a horizontal and tuberous 

 white rootstock (which has the taste of cucumber), bearing near the middle a 

 whorl of 5 - 9 oboA-ate-lanceolate and pointed, sessile, lightly parallel-ribbed 

 and netted-veiny, thin leaves; also another of 3 (rarely 4 or 5) much smaller 

 ovate ones at the top, subtending a sessile umbel of small recurved flowers.

Sepals 3, lanceolate, spreading, herbaceous, persistent. Petals 3, larger, 

 withering in age. Stamens 6 ; anthers linear, on short filaments, adnate, usu-
