5a. Arabis Georgiana Harper. Biennial. Stem 3-5 dm. tall, with few erect 

 branches mostly from the base, minutely hirsute below, glabrous or nearly so above : basal 

 leaves 6-8 cm. long, in a flat rosette ; blades oblanceolate or spatulate, coarsely toothed : 

 cauline leaves spreading or ascending ; blades 3-6.5 cm. long, oblong-lanceolate to lanceo- 

 late or linear-lanceolate near the inflorescence, sessile and half-clasping, bright green, the 

 lower surface and the margins sparsely pubescent with both simple and forked hairs : 

 racemes becoming 3 or 4 dm. long : pedicels ascending, glabrous, becoming 1 cm. long : 

 sepals ovate, 4 mm. long, acute, narrowly scarious-tnargined : petals 9-10 mm. long, white, 

 obtuse : style 1 mm. long : pods linear-filiform, flattened, 6-7 mm. long, about 1 mm. 

 wide, erect or nearly so, the valves 1-nerved : seeds narrowly winged, in 1 row. 



On shaded banks, along the Chattahoochee River, Georgia. Spring. Differs from A. patens in the 

 longer pods and the glabrous upper surface of the leaves and the upper part of the stem, and from A. 

 hirsuta in its larger corolla, evident style and longer pods.

 " except in Liquidambar." 



Page 502, extend the range of Lepuropetalum spatulatum to Texas and Mexico. 



Page 522, in fourth and fifth lines of the key under Geum, interchange the words 

 " glabrous" and " bristly." 



Page 555, in fifth line under Crataegus dispar, read " petioles" for "pedicels."

4. Medicago sativa L. Stem decumbent or ascending, 3-5 dm. long, more or less 

 branched, usually sparingly pubescent : leaflets 3, the blades cuneate-obovate to cuneate or 

 oblanceolate, mainly 1-1.5 cm. long, sharply toothed near the apex, rather prominently 

 but finely veined : racemes several-flowered, peduncled : calyx 4-5 mm. long ; lobes 

 nearly subulate, about as long as the tube, sparingly ciliolate : corolla violet or blue, 7- 

 8.5 mm. long ; standard oblong-obovate ; wing-petals each with a hooked spur at the base 

 of the blade : pods 2 or 3 times spirally twisted, finely pubescent, the valves delicately re- 

 ticulated. 



In fields and waste places, Quebec to Manitoba, Virginia and Texas. Naturalized from Europe. 

 Summer.

26a. ARAGALLUS Neck. 



Herbs or shrubby plants, similar to species of Astragalus in habit ; but keel petals acu- 

 minate, abruptly pointed or appendaged at the apex. 



1. Aragallua Lambertii (Pursh) Greene. Stems very short, several from a branched 

 caudex, clothed with the persistent leaf-bases : leaves erect or ascending, 0.5-1.5 dm. tall ; 

 leaflets several, the blades linear or nearly so, 1.5-2.5 cm. long, acute or slightly acumi- 

 nate, silky on both sides : scapes 1.5-3 dm. tall, silky strigose : bracts narrowly linear-lan- 

 ceolate : calyx densely pubescent, 10-11 mm. long ; lobes nearly subulate, the lower one 

 markedly longer than the others : corolla violet, purple or white, 16-19 mm. long ; stand- 

 ard rounded at the apex, cuneately narrowed at the base ; blades of the keel and wing-petals 

 longer than the claws, about thrice as long as broad : pods narrowly conic, 18-20 mm. long, 

 subulate-tipped. 



On plains, the Northwest Territories to Minnesota, British Columbia, Texas and New Mexico. 

 Spring and summer.

9. TRIPHASIA Lour. 



Shrubs, with smooth green branches, more or less thorny. Leaves alternate, persis- 

 tent, 3-foliolate, the leaflets with leathery shallowly toothed blades. Flowers perfect, 

 regular. Sepals united into a 3-5-lobed shallow calyx. Petals 3-4, narrow. Stamens 6 

 or 8, borne at the base of a fleshy disk : filaments dilated at the base : anthers narrow. 

 Ovary 3-celled : styles united. Ovules solitary and pendulous in each cavity. Berry rela- 

 tively small, 1-3-celled. Seeds imbedded in pulp. Embryo with unequal, often lobed, 

 cotyledons. 



1. Triphasia Aurantiola Lour. A much-branched armed shrub. Leaves numerous, 

 glabrous; leaflets 3, the blades ovate to nearly oblong or oval, 1.5-3.5 cm. long, obtuse,
