Order 79. PEDALIACEiE. 



Herbs, with cJiie/h/ opposite simple leaces, and jloicers as of the preced-

 the latter fleshy-drupaceous, with wingless seeds and thick- entire cotyledons.

1. MARTYNIA, L. UxicoRN-ri.ANT. 



Calyx 5-cleft, mostly unequal. Corolla gibbous, bell-shaped, 5-lobed aud 

 somewhat 2-lipped. Fertile stamens 4, or only 2. Fruit fleshy, the flesh at 

 length falling away in 2 valves ; the inner part woody, terminated by a beak, 

 which' at length splits into 2 hooked horns, and opens «at the apex between the 

 horns, imperfectly 5-celled, owing to the divergence of the two plates of each 

 placenta, leaving a space in the centre, while by reaching and cohering with 

 the walls of the fruit they form 4 other cells. Seeds several, wingless, with a 

 thick roughened coat. — Low branching annuals, clammy-pubescent, exhaling 

 a heavy odor, stems thickish; leaves simple, rounded ; flowers racemed, large.
