4 (a). O. vespertilionis : stemlcss; bulb solitary, scaly ; leaves 3-foliolate, 

 and, with the whole plant, glabrous; leaflets dilated, broadly euneate at the 

 base, 2-lobed; the lobes oblong, divaricate; scape S-S-flowered, longer than 

 the leaves; pedicels 2-3 times as long as the flowers; sepals linear-oblong, 

 with 3-4 glands at the tip; petals (violet) narrowly oblong, entire; filaments 

 glabrous, toothless, the longer ones much shorter than the hairy styles. 



Texas, Drummmul ! — Bulb about the size of a ha7.el-nut, clotiied with 

 brown scales. Petioles 3-5 inches long. Leaflets about an inch wide and 

 scarcely one-third of an inch froni the base to the inner angle of the notch; 

 the lobes rather obtuse. Peduncle 5-8 inches long : longer pedicels an inch 

 or more in length. Flowers smaller than in O. violacea. Se])als witli 

 several confluent orange-colored glands at tlie tip. — Apparently allied to 

 O. latifolia, Kunth, but differs in being quite glabrous in the narrow lobes of 

 the leaves, and in the toothless filaments. From O. violacea it is readily 

 distinguished by the form of the leaves. 



Order XXXI (a). OCHNACEiE, DC. 



Sepals 4-5, persistent: aestivation imbricate. Petals hypogy- 

 nous, as many as the sepals or rarely more numerous, deciduous, 

 spreading, imbricate in estivation. Stamens as many or twice 

 as many as the petals, or sometimes indclinite, inserted on the 

 hypogynous disk : filaments persistent : anthers innate or introrse, 

 usually opening by pores. Carpels equal in number with the 

 petals, distinct or sometimes more or less combined, seated on the 

 enlarged tumid fleshy disk (gynobase) ; tlieir styles combined into 

 one, which springs directly from the disk between the bases of the 

 ovaries : ovules solitary, erect or sometimes pendulous. Fruit of 4-5 

 or more drupaceous carpels, articulated with the torus. Seed 

 anatropous, destitute of albumen. Radicle short : cotyledons thick.

 stipulate leaves.
