 apex, the segments usually toothed : fertile stems erect, simple, 2-4 dm. long, surmounted 

 by usually 2 petioled leaf-blades similar or nearly similar to that of the sterile stem, but 

 attached at or near the margin : pedicel stout, 2-4 cm. long, arising between the petioles : 

 flower nodding : bracelets 3, green, caducous : sepals 6, fugacious : petals 6-9, obovate, 

 2.5-4 cm. long, wax-like, white : berry obliquely oblong or ovoid, 4-5 cm. long, greenish 

 yellow, tipped with the black remains of the style.

 anthers opening by 2 valves. Ovary 1-celled : style wanting : stigma 2-lobed. Ovules 

 numerous, in many rows. Capsule leathery, broadest at the top, opening by a terminal lid. 

 Seeds numerous, each with a fleshy cleft aril. TWIN-LEAF. 



1. Jeffersonia diphylla (L.) Pers. Foliage glabrous, more or less glaucous. Leaves 

 basal, tufted ; petioles erect, 1-3 dm. tall ; blades 2-parted, the segments obliquely reni- 

 form, 5-10 cm. long, nearly entire or coarsely crenate, becoming deep green above, 

 glaucous beneath : scapes erect, about equalling the petioles in length or a little longer at 

 maturity, simple : sepals oblong-oblanceolate, 1.5-2 cm. long, obtuse : petals white, similar 

 to the sepals, often a little longer: capsule obovoid or obconic, 1.5-2 cm. long, short-
