Arkansas, April 27, 1905, and distributed as Adelia pubescens (Nutt.) 

 Ktze., may be taken as the type of this variety. Mr. Bush's speci- 

 mens were in flower and young leaf. The pubescent variety is also 

 represented by the following additional specimens in the Arnold Arboretum 

 Herbarium : 



Arkansas. Van Buren, Crawford County, E. J. Palmer, No. 21008, April 29, 

 1922, with young fruit; Fulton, Hempstead County, B. F. Bush, no. 5458, April 5, 

 1909, with flowers, young leaves and pubescent old branchlets; Miller County 

 (opposite Fulton), E. J. Palmer, No. 22268, October 11, 1922, with old leaves 

 densely pubescent beneath, and pubescent branchlets. 



Louisiana. Richland, Rapides Parish, R. S. Cocks, No. 19, June, 1908. 



APOCYNACEAE 

 Trachelospermum difforme (Walt.) A Gray. Low woods, thickets and 



borders of bogs. 



VERBENACEAE 



Callicarpa americana L. A rather common shrub found sometimes in 

 openings of low woods, but more abundant in the uplands and sandy 

 section. 



BIGNONIACEAE 



Catalpa speciosa Engelm. Several small specimens of this species were 

 seen along a small sandy creek near McNab, but I am inclined to think it 

 is a recent introduction here from cultivated trees. 



Campsis radicans (L.) Seem. Growing along small streams in the sandy 

 section and sometimes along open banks throughout. 



Bignonia capreolata L. A high climbing vine, not uncommon in woods. 



RUBIACEAE 



Cephalanthus occidentalis L. Very common in opening of low woods 

 and in swamps and bogs. 



Cephalanthus occidentalis var. pubescens Raf. The pubescent form is 

 sometimes found along sandy streams and in sandy bogs. 



CAPRIFOLIACEAE 



Viburnum rufidulum Raf. A common small tree growing both in bot- 

 toms and uplands, but most abundant in thickets and openings along the 

 escarpment. 



Symphoricarpos orbicularis Moench. Sometimes found in thickets and 

 openings in woods, but not very common. 



Lonicera sempervirens L. Found in thickets along small streams, es- 

 pecially in the sand hills section. Some of the specimens collected here 

 have rather narrow oblong leaves, finely pubescent beneath, and small 

 flowers, and may represent a distinct variety. 



Sambucus canadensis L. Often common in open woods in the bottoms 

 and in thickets alonsr small streams. 



t> 



Sambucus canadensis var. submollis Rehd. This pubescent form is 

 often abundant along small creeks in the sand-hill sections.
