310 PAT AGONIAN EXPEDITIONS : BOTANY. 



1. ZEPHYRANTHES Herb. 



Glabrous herbs, with a bulb sending up narrow leaves, and a hollow, 

 leafless i -flowered scape. Perianth funnelform, usually with scales in its 

 throat. Style 3-lobed. Capsule subglobose, 3-lobed. 



Species 30, New World, from Tex. southward ; i in W. Afr. 



1. Z. ANDERSONII (Herb.) Benth. * 



Stamens unequal, declined (but often normal). Perianth-scales united 

 into a membrane at the base of the filaments ; anthers dorsifixed. (Fig. 

 in Eng. & Prantl, ii, 5, p. 107.) 



(Argentina) ; N. Patagon. Has golden-copper-colored flowers ; and 

 springs up commonly after rains. 



2. Z. MELANOPOTAMICA Speg. 



Euzephyranthes. Bulb ovoid, mediocre, fuscous-tunicate. Leaves nar- 

 row-linear, long, green, not synanthous. Scapes erect, more or less 

 elongate, terete, glabrous. Spathes elongate, bifid below the middle, 

 more or less long-connate, whitish. Flowers solitary or paired, erect, 

 pedicels shorter than spathe. Perianth turbinate, mediocre, its leaves 

 oblanceolate, acutish, white, twice as long as the unequal glabrous sta- 

 mens, basally short-tubular-connate. Interstaminal scales small, pectinate- 

 ciliate. Style rather long, included, trifid. 



N. Patagon., in dunes along Rio Negro. Differs from Z. mesochloa 

 Herb, by the leaves not being synanthous, and by the ciliate-pectinate 

 character of its interstaminal squamules. 



2. HIPPEASTRUM Herb. 



Coated bulb sending up a fistulous stem with strap-shaped leaves, and a 

 2-many-flowered umbel (rarely i-flowered), often large; with 2 distinct 

 involucral bracts, often enclosing i-many inner linear or filiform bracts. 

 Perianth-tube short or long, the limb often zygomorphous. Filaments 

 short; anthers dorsifixed, versatile. Crown of scales about or between 

 the stamens small. Ovary 3-celled. Seeds many, black. 



Species 50, in subtropical Amer. Section Habranthus has broad fun- 

 nelform flowers, few in the umbel, and narrow leaves.
