Nemopanthus Celastraceae 653 



but with a limited amount of field study I am not able to determine 

 whether these differences are ecological or morphological. 

 Mass. to Minn, and southw. 



4615. NEMOPANTHUS Raf. 



1. Nemopanthus mucronata (L.) Trel. Mountain Holly. Map 1356. 

 In swampy and boggy places about lakes and in wet woods in the lake area. 

 Infrequent. 



Newf . to Wis., southw. to Va. and Ind.

4618. EVONYMUS [Tourn.]]L. 



Petioles of terminal pair of leaves over 4 mm long; capsules smooth 



1. E. atropurpureus. 



Petioles of terminal pair of leaves not over 4 mm long; capsules tuberculate. 



Erect or ascending shrubs; terminal leaves ovate-lanceolate, thin, capsules Spinel 



Red (Ridgway Standard) 2. E. americanus. 



Creeping shrubs with upright or ascending branches; terminal leaves obovate, firm; 

 capsules scarlet- or orange-red (Ridgway Standard) 3. E. obovatus. 



1. Evonymus atropurpureus Jacq. Wahoo. Map 1357. An infrequent 

 to frequent shrub on the alluvial banks of streams throughout the state. 

 It is rarely found far from water courses or in dry situations. 



N. Y. to Minn., southw. to Fla. and e. Tex. 



2. Evonymus americanus L. BROOK EVONYMUS. Map 1358. Found in 

 a few of the southern counties where it grows in low, flat woods with sweet 

 gum, beech, and pin oak, and rarely in dry ground with black and white 

 oak. There is an ascending form of this species that has leaves inter- 

 mediate between this and the next species but it grows with the species 

 and has the typical fruit. This species has been reported for some of the 

 northern counties but I think all reports from there should be referred to 

 Evonymus obovatus. 



N. Y. to 111., southw. to Fla. and Tex. 



3. Evonymus obovatus Nutt. Running Evonymus. Map 1359. Infre- 

 quent in rich, moist soil, mostly in beech and sugar maple and white oak 

 woods. It is to be noted that we have no records for the extreme south- 

 western counties although I have botanized this area intensively. 



Ont. to Mich, and 111., southw. to Pa. and Ky. 



4625. CELASTRUS L. 



1. Celastrus scandens L. American Bittersweet. Map 1360. Rather 

 frequent throughout the state in moist or dry soils. Mostly along fences 

 and more rarely in thick woodland except in the sandy woods of the south- 

 western counties. 



Maine to Man., southw. to N. C, Tenn., and N. Mex.
