IO76 APPENDIX. 



P. 456, after Dentaria maxima, insert: 



3a. Dentaria incisifolia Eames. Cut-leaved Tooth-wort. Much 

 resembles D. maxima, the rootstock similar, with fusiform joints. Stem- 

 leaves 2, opposite or nearly so, similar to the long-petioled basal ones; 

 leaf-divisions sessile (stalked in D. maxima), incised-dentatc; pedicels 



3 cm. long or less; petals about 2.5 times as long as the sepals (about 

 twice as long in D. maxima). Sherman, Conn. \_D. incisa Barnes, not 

 Small.] 



Dentaria anomala Eames, from Plain ville, Conn., growing with D. diphylla and D. 

 laciniata, may be a hybrid of these two species. 



P. 457, after Physaria didymocarpa, add: 



2. Physaria brassicoides Rydb. Cabbage Bladder-pod. Root 

 thick and deep, the tufted leaves forming a large rosette often 1 dm. in 

 diameter and resembling a small head of cabbage. Basal leaves sinuate- 

 dentate, long-petioled, the blades obovate to nearly orbicular, obtuse, 

 the petioles margined; flowering stems ascending, about 1 dm. high, 

 their leaves small, spatulate; fruit nearly obcordatc, acute at the base, 

 deeply lobed above, grooved, 8-10 mm. long, densely stellate-canescent; 

 style about 5 mm. long. Rocky places, western Ncbr. and N. Dak. 

 June. 



P. 465, before Erysimum asperum, insert: 



3a. Erysimum repandum L. Repand-leaved Erysimum. Annual 

 or biennial, 2-4 dm. high, more or less rough-pubescent. Leaves lanceo-

 upper repand-dentate or entire; pedicels short, stout; flowers about 



4 mm. high, yellow; stigma slightly 2 -lobed; pods narrowly linear, as-

 places, Ohio, Mo. and Ariz. Adventive from Europe. May-July. 



P. 482, after Heuchera villosa, insert: 



Heuchera macrorhiza Small. Big-rooted Heuchera. Similar to H. 

 villosa, but stouter, the rootstock thicker and woody; pubescence of the 

 stem and petioles denser; leaf-lobes shorter and broader, their margins 

 copiously villous-ciliate; pedicels more villous than the turbinate calyx; 

 capsule longer, twice as long as the calyx. River-banks, Term, and Ky. 



P. 513, after Rosa setfgera, insert : 



ia. Rosa bracteata Wendl. Evergreen Rose. A shrub with dark

 to oval, 1-2 cm. long, often cuncate at the base, retuse, truncate or 

 apiculate at the apex, serrate, shining above; flowers few together or 

 solitary; sepals acuminate, reflexed when old. persistent on the fruit;
