prominent beneath; fruit orbicular, about 2 mm. long, constricted at the 

 commissure. In wet soil, Va. and Ky. to Fla. and La. June-Aug. 



ib. Cicuta occidentalis Greene. WESTERN WATER-HEMLOCK. Similar 

 to Cicuta maculata, the oval to oblong fruit constricted at the commissure, 

 the ribs all projecting about equally, while in C. maculata the fruit is not 

 constricted at the commissure, and the lateral ribs are much the largest; 

 veins prominent on the lower surface of the leaflets. In wet soil, S. Dak. 

 and Neb. to Idaho and N. Mex. June-Sept. 



P. 685, for " Cymopterus montanus T. & G." read " Phellopterus mon- 

 tanus Nutt." The genus Phellopterus Nutt. differs from Cymopterus Nutt., 

 as shown by Coulter and Rose. 



P. 687. Substitute for genus 44. PEUCEDANUM L., the name LOMA- 

 TIUM Raf. As shown by Coulter and Rose, the Old World Pcucedanums 

 are generically distinct from the North American plants which have been 

 so called. Our species, according to these authors, are as follows: 



1. Peucedanum nudicaule = Lomatium orientate C. & R. 



2. Peucedanum foeniculaceum = Lomatium foeniculaceum (Nutt.) C. 

 & R. 



3. Peucedanum Kingii is referred to Cynomarathrum Kingii (A. Gray) 

 C. & R. 



4. Peucedanum villosum = Lomatium daucifolium (Nutt.) C. & R. 



P. 749, at end of Asclepiadaceae, add: 



7. PERIPLOCA L. 



Woody twining plants with entire opposite leaves and middle-sized 

 flowers in umbels. Calyx 5-parted, glandular within; corolla deeply 5- 

 parted, the segments obtuse, dextrorsely rotate, villous on the inner sur- 

 face; corona adnate to the base of the corolla, with 10 broad or 5 slender 

 elongated, entire or lobed scales or appendages; filaments short, free, 

 conniving at the short appendiculate apex; pollen granulose, loosely 

 aggregated in two masses in each anther-cell; follicles slender, glabrous, 

 generally united at the apex; seeds comose. (Greek, twining.) 



i. Periploca Graeca L. Glabrous; leaves ovate-oblong, acute, paler be- 

 neath; umbels cymose; peduncles shorter than the leaves; corolla-seg- 

 ments dull brownish or greenish, with a darker line down the middle and 

 a whitish spot at the base within; appendages of the corona slender, ligu- 

 late, 2-toothed at the apex. A handsome woody climber of the Old 

 World, escaped from cultivation, Mass, to Kans. Native of Syria and 

 the Grecian Islands. Called SILK VINE. 



P. 782, after Teucrium occidentale, insert: 



2a. Teucrium littorale Bicknell. COAST GERMANDER. Pale and canes- 

 cent, 3-5 dm. high, erect or assurgent, often with ascending branches; 

 leaves thickish and rugose-veiny, narrowly oblong or sometimes broader, 

 narrowed into the petiole, closely fine-serrate or becoming unequally 

 dentate-serrate, 6-n cm. long, 1.5-4 cm - wide; petioles 5-10 mm. long; 

 spikes narrow, often interrupted; bracts about the length of the calyx; 

 calyx small, 4-5 mm. high, becoming somewhat gibbous-urceolate, the 

 teeth short, the upper ones obtuse; corolla pale pink, about 15 mm. long, 

 loosely pilose without. On or near the coast. Me. to Fla. July-Aug. 



2b. Teucrium roseum Bicknell. MAINE GERMANDER. Rather stout and 

 deep green, 3-7 dm. high, the stem soft-pubescent or downwardly villous; 

 leaves broadly oblong or oblong-ovate, cuneate at base, acute or acuminate 

 at apex, irregularly dentate-serrate or somewhat cut-serrate, hoary- 

 tomentose beneath, softly pilose-pubescent above, 6-9 cm. long, 2.5-4.5 

 cm. wide, the slender petioles hoary-pubescent, 10-15 mm. long; inflores-
