folious spikes or racemes ; pedicels short ; bracts membranous, rather 

 broad, concave above, appressed to legume, sprinkled with glandular 

 dots, subscarious or setaceous ; bractlets {North, Central, and Andine 

 America, Chili 1 ). 



99. Marina? Liebm. 2 — "Lobes of calyx nearly equal, dentate 

 ciliate. Standard long-unguiculate, obovate rotundate ; wings fal- 

 cate obovate ; keel cucullate, shorter than standard or wings. Sta- 

 mens 10, all connate into a sheath cleft above; anthers uniform. 

 Germen sessile 1 -ovulate; style filiform glabrous; stigma simple. 

 Legume included by calyx, membranous indehiscent. Seed sub- 

 reniform. — A herb, tender annual diffuse, sprinkled with violet 

 dots ; leaves imparipinnate ; leaflets oo, very small, quite entire, 

 minutely stipellate ; stipules broad scarious dentate ; racemes 3 extra- 

 axillary or leaf-opposed ; peduncle filiform ; bracts minute scarious" 

 {Mexico*). 



100. Petalostemon Michx. 5 — Calyx gamosepalous and rather 

 inflated at base ; teeth or lobes nearly equal, more rarely posterior 

 one larger than others. Petals very dissimilar ; standard broadly 

 cordate or reniform, concave or cupulate ; claw thin slender ; wings 

 somewhat similar to and often shorter than petals of keel, very 

 oblique, oblong ; claw thin, nearly free or adnate to base of andro- 

 ceum. Stamens 5, oppositipetalous ; filaments scarcely perigynous, 

 connate at base into a sheath cleft above ; anthers uniform, often 

 surmounted by a dorsal gland. Germen sessile or scarcely stipitate ; 

 style subulate, much inflexed in aestivation ; stigma terminal, usually 

 minute and not thickened. Ovules 2, amphitropous, collaterally 

 descending ; micropyle extrorse superior. Fruit small, included by 

 calyx, membranous, usually indehiscent, 1 -seeded. Seed reniform
