 blades narrowly elliptic to obovate-oblanceolate, 6-8 cm. long, 9-11-nerved, the margins 

 translucent : racemes slender, 2-4 dm. long : perianth white, obovoid, 5-6 mm. long ; 

 lobes ovate, converging : filaments adnate to a little above the middle of the perianth : 

 style very short. 



In pine lands, Jacksonsville, Florida. Spring and summer. 



2. LOPHIOLA Ker. 



Caulescent herbs, with slender rootstocks and more or less pubescent foliage. Leaves 

 mostly basal : blades narrow, entire. Flowers in terminal dichotomous cymes. Perianth yel- 

 lowish, persistent, pubescent : sepals and petals 3 each, relatively long, nearly equal. 

 Stamens 6 : filaments adnate to the base of the perianth : anthers not versatile. Ovary 

 3-celled, half-inferior : style subulate, partly seperated at maturity. Ovules numerous, in 

 2 rows in each cavity. Capsule ovoid, loculicidally 5-valved at the apes. Seeds ribbed. 



1. Lophiola Americana (Pursh) Wood. Foliage glabrous below, woolly above. Stems 

 5-8 dm. tall, terete, corymbose above : leaves equitant ; blades linear, much shorter than 

 the stem, glabrous or nearly so, the upper reduced to narrow scales : cymes dichotomous : 

 perianth yellow and glabrous within except a tuft of hairs near the base : sepals and petals 

 linear-lanceolate, 4-5 mm. long, acute, woolly without : capsules 2 mm. long, included in the 

 perianth, about as long as the persistent style. [Lophiola aurea Ker.] 



In pine lands, New Jersey to Florida. Spring and summer. 



3. HYPOXIS L. 1 



Acaulescent herbs, with corm-like rootstocks and usually pubescent foliage. Leaves 

 basal : blades narrow, grass-like. Scapes solitary or tufted, terete or flattened. Flowers 

 solitary or in umbel-like clusters. Perianth often yellow within, withering-persistent : 

 members 6, equal or nearly so. Stamens 6 : filaments short, adnate to the base of the 

 perianth : anthers erect. Ovary 3-celled : stigmas 3. Ovules numerous, in 2 rows in each 

 cavity. Capsule subglobose or elongated, circurascissile. Seeds laterally short-beaked.
