 above, curved : scapes solitary or 2-3 together, wiry-filiform, 1-2-flowered, usually over- 

 topped by the leaves, decumbent or procumbent at maturity : bracts subulate : perianth

2. Hypoxis micrantha Pollard. Corm globose, 5-8 mm. in diameter : plant about 

 1 dm. high : leaf-blades very narrowly linear (1 mm. to nearly 2 mm. wide), channeled, 

 hirsute with copious slender spreading hairs, the base only slightly sheathing : scapes very 

 short (3-7 cm. ), 2-flowered : perianth when expanded about 6 mm. broad : sepals an*d 

 petals, and anthers, similar to those of H. juncea, but relatively more narrow. 



In wet woods, Carteret County, North Carolina. Spring and summer. 



3. Hypoxis Curtissii Rose. Corm small : leaf-blades glabrous, linear, much elon- 



fated, 3-5 dm. long, 10-20 mm. broad, weak and spreading : scapes rather short, 

 -flowered : pedicels slender, erect: bracts elongated: sepals and petals (in fruit) erect, 

 narrow, 6-8 mm. long : capsules oblong, 6 mm. long, many-seeded. 

 In sandy soil, northern Florida. Spring and summer. 



4. Hypoxis grandis Pollard. Plants clustered, 3-4 dm. high, a number growing 

 from a single large corm : leaf-blades linear, with a maximum width of 7 mm., sparsely 

 hirsute, prominently 3-5-nerved, their lower portions expanded into broad membranous 

 sheaths : scapes rather stout, equalling or somewhat shorter than the leaves, 5-9-flowered : 

 perianth 1-2 cm. broad, densely hirsute without. 



In clay soil, southern Alabama. Spring and summer. 



5. Hypoxis hirsuta (L. ) Coville. Plants usually solitary: leaf -blades linear, 1-4 

 dm. long, often slightly involute, attenuate, the midrib impressed above, forming a keel 

 beneath : scapes solitary or several together, 0.3-5 dm. tall, simple below, usually umbel- 

 lately branched above : pedicels 1-2.5 cm. long, subtended by linear-subulate bracts : 

 perianth pubescent without : sepals and petals oblong or elliptic, 6-7 mm. long, yellow 

 within, greenish without : capsules globose or obovoid, 4-5 mm. long : seeds oblong or 

 subglobose, 1.5 mm. in diameter, black, minutely granular-papillose. [H. erevta L.] 



In dry or sandy soil, Maine to Ontario, Assiniboia, Florida and Texas. Spring to fall. 



4. MANFRED A Salisb. 1 



Fleshy herbs, the plants arising annually from bulbs borne on more or less thickened 

 rootstocks, and dying down annually. Leaves mainly basal : blades neither spiny-edged 

 nor spine-tipped. Flowers in narrow terminal spikes or racemes. Perianth rather incon- 

 spicuous : sepals and petals partially united, the lobes nearly equal. Stamens 6 : filaments 

 more or less adnate to the perianth-tube : anthers versatile. Ovary 3-celled : style slender. 

 Ovules in 2 rows in each cavity. Capsule 3-celled. Seeds flattened. FALSE ALOE. 



Filaments adnate to the base of the perianth- tube. 



Capsules longer than broad : leaves green. 1. M. Virginica. 



Capsules broader than long : leaves purple-blotched. 2. M. tigrina. 



Filaments adnate to near the top of the perianth-tube. 



Stamens much longer than the perianth-lobes : stigmatic lobes rounded : capsules 



much longer than broad. 3. M. variegata. 



Stamens about as long as the perianth-lobes : stigmatic lobes notched : capsules 



about as broad as long. 4. M. maculosa. 



1. Manfreda Virginica ( L. ) Salisb. Basal leaves 6-15 ; blades lanceolete, oblong 

 or oblong-spatulate, 1-3 dm. long, 3-5 cm. broad, herbaceous-tipped, obscurely and rather 

 irregularly serrulate, not mottled : stem 8-18 dm. tall, simple : bracts as long as the ovaries 

 or shorter : raceme loosely flowered : perianth greenish or brownish yellow ; tube narrowly 

 funnelform ; lobes linear-oblong, 10-12 mm. long : filaments narrowly clavate, adnate to 

 the base of the perianth-tube : anthers 12 mm. long : capsules 15-20 mm. long, longer than 

 broad : seeds 4-6 mm. long. 



In sandy soil, Maryland to Missouri, Florida and Texas. Spring and summer. 



2. Manfreda tigrina (Engelm.) Small. Basal leaves several ; blades lanceolate or 

 oblong-lanceolate, 3-5 dm. long, 5-7 cm. broad, acute or cuspidate, with herbaceous tips, 

 mottled with green and purple : stem 10-25 dm. tall, simple : raceme several-flowered :
