XYI. TOFIEkBIA. TOFIELDIA. 



Herbs, with creeping rootstocks, grass-like, chiefly radical leaves,

 and small yellow flowers in terminal spikes. Perianth of 6 distinct seg-

 Ovary 3-lobed, with 3 distinct styles. Capsule small, 3-lobed, with 

 several small, oblong, brown seeds. 



A small genus, chiefly North American, extending along the Andes 

 to tropical America, and westward across northern Asia to Europe. 

 In its free styles it shows some approach to TriglocJiin in the Alisma

 by a little globular or ovoid spike or head ; the perianth not quite 

 a line long. The very short pedicels are each in the axil of a mi- 

 nute bract, and within that bract is a still smaller 2-lobed or 3-lobed 

 one, sometimes quite imperceptible, but never placed at the top of
